[Yoda]

its like 118 on the NST website tho

[battleversiontc]

thats only for the crank pulley i have all three the crank water and alt pulley for 250 shipped its 118 on nst plus the 160 so total 278 and idk how much shipping is for them if its free or not cause microimageonline is freee shipping

[Yoda]

o ok i just want the crank pully tho

[battleversiontc]

he sells them for 112 free shipping on his website

[cleong]

INFO for Thailand Yaris:

The alternator pulley is different than US version.

The rest is sooooo goooood!
So much better for throttle response and engine REV up.
(I've post it before and I don't mind posting it again now)..

NST FTW!


Does that mean the NST Alternator pulley won't fit? Did you buy the 3-pulley kit but was only able to fit 2 of them?

I bump this question.

Gains are very similar on both auto and manual cars. Weight reduction is very noticeable, and the principle of underdriving also applies equally, regardless of transmission type.

We have done A LOT of testing with automatics, and gains have always been there across the entire RPM band.

:thumbsup::thumbsup:

[battleversiontc]

Engine braking is a little better but is negligible. I have no idea about the auto. Anyone care to comment on the auto?

engine braking is still the same no change it actually was noticable just with the intake that add alot of engine braking but the difference is noticable on the auto but the engine braking is more back to stock i have all three pulleys. but love it going up hill is like butter now. exhaust and headers are next then ill work the suspension after

YUP.. :frown:
Now it's only good for paper weight. I've tried to sell it to Swift owner (it seems could work with that alternator).. but so far, no luck. :tongue:

[lamdog]

received a underdrive pulley from Gram today..
tried to fit it, but no luck... the bolt is freaking hard.
i have also tried an electric drill to take it off, the bolt did not move at all.
sighs... gonna take the pulley to my mechanic this weekend, i cannot wait....

[battleversiontc]

yeah i had to use an impact gun to remove the bolt for the crank
and a 10mm wrench for the water pump pulley along with a thick srew driver through the holes to loosen the water pump pulley bolts and i just impacted the alt pulley it was all good after that

[lamdog]

got my underdrive pulley on today...
took it to my mechanic, it was just a piece of cake with air tool....
i could notice that the throttle is much lighter right after the pulley was on...
no unusual vibration after.

[NonStopTuning]

Thank you sir :thumbsup::thumbsup:

im waiting to find out the differences with the mpg on these i hope to see alot of improvement on this since now i dont really push the gas down as much now

Here are the official results of an honest back-to-back dyno test of the NST pulleys (crank, alt & WP). Car was run on the dyno with stock pulleys and then we swapped out the stock pulleys for the NST (I believe 10% under driven) though sizing on WP and Alt looked the same. Pulleys were definitely worth some power as indicated by grpah. Note also the power numbers (123 wheel hp) is a new NA record-posted elsewhere with description of mods.


Thanks again Richard, your hard work and dedication is much appreciated :thumbsup::thumbsup:

Is that dyno a stock car vs the same stock car with stock pulleys removed and NST pulleys (including 10% underdrive)? Were there no other engine/exhaust mods?

[RagnaCaT]

One with pulleys and one without thats about 3hp!:drool:

There are a lot of other modifications on that Dyno chart. Intake Manifold, custom long tube header, and others.

However, is important to mention that NON of those other mods modify in no way the output / gains provided by the pulleys.

That means that the 3whp gain all across the power band will be the same on an unmodified car.:w00t:


And yes, that is a complete pulley set including the 10% underdrive crank pulley.

[whooppee777]

i know this was discussed once before, and was probably lost due to the hack.

i will be boosted with the blitz supercharger most likely after christmas and i was wondering if a different pulley could be made or maybe even a light weight pulley could be made for the blitz supercharger? if a pulley were made to make more boost wouldnt u have to retune whatever fuel managment comes with the blitz kit?

[NonStopTuning]

Please contact us when you have your BLITZ charger installed and I would be more than happy to chat with you and answer all your questions.

There are options for the SC.

[whooppee777]

well if you made a pulley you would probably need a pulley from the kit in order to make a different one correct? and if i install mine my pulley it isnt coming off cuz i this is my only daily driver. so if anything could be done you would need the pulley before i install it. if you used me as a test dummy. perhaps i could talk cali yaris to send me the pulley from my kit he is holding for me so u could possibly get a head start. would that be cool?

but i am right in needing to have the Fuel management remapped if i went with a different size pulley right? cuz i would b changing boost levels and consequently needing more fuel.

but if you made a light weight pulley, in a bitchn anodized red to match my other lite pulleys, boost levels wouldnt change. just a slight increase in responsivness of the supercharger kicking in right?

[NonStopTuning]

I have already seen the BLITZ SC pulley. This pulley has a clutch type mechanism attached to it, and can not be reproduced feasibly in small numbers.

We are looking at options for raising boost via the crank pulley. Using a slightly larger crank pulley would raise boost, and could possibly work without needing any reprogramming of the ECU. We won't know until we have a test car to play with.

This is all just theoretical at this point... we won't know until we are able to try, which means we would need someone to step up to the plate and help out. Like I said, contact us once your SC is in your car and is fully operational.

Thanks again!

We actually have quite a few automatic owners out there...
unfortunately about 30 pages of the testimonies and feedback was lost in the recent hack.

The principles of weight reduction and underdrive apply in both auto and manual cars.
Dropping weight from the rotating assembly = increase in response and power delivery.

Hey Mike,

Just a little report for your records.


The NST SSK does NOT fit in the new (2009) 6 speed tranny.

The new Yaris TS comes equipped with a brand new 6speed MT and I verified last week that the SSK wont work on this new tranny.

I believe that Toyota will be using this same tranny also for the Euro 2009 Yaris 1.3L and other compact models.

I was thinking of getting the NST pulleys, but didn't want the invest in the whole set yet. As it cost queit abit. I was just wondering from what i've read the Underdrive Crank Pulley would provide the most gains? Is there much of a difference in gained power from say Crank+Alt+Water Pulleys and just Crank Underdrive by itself?. Im thinking of just getting the Underdrive first and might skip the rest if they don't provide as much of an improvement.

[Klink10]

Ruimond

I wish I could give you a solid answer on that, but it would be from the Butt dyno vs real world figures. I did mine with the regular crank pulley plus alt. and WP from NST until they came out with the underdrive. Then I went to that. NST should have some figures somewhere here on the breakdown in gains...where I don't know. Send them a msg. and ask. Or ask Calis Yaris at Micro Image he lists their products and I'm sure can give you an answer or steer you to what you want to know.

[NonStopTuning]

The Underdrive Crank Pulley is definitely the way to go if you can only afford to pick up one pulley.

Let's put it this way...

Want the ABSOLUTE best gains from your n/a or turbo setup? Pick up the Underdrive Crank Pulley along with the Alternator and Water Pump Pulley Kit.

On a budget and want 65% to 70% of the performance you would get if you had the FULL setup? Then go with the Underdrive Crank Pulley alone and pick up the other pulleys in the future.

The majority of our customers pick up a crank pulley and then come back for the other two pulleys a few months later, once they experience the gains from the crank pulley.

Good luck and have fun with all your projects!

im not sure if i posted this or not but i picket up the complete set on ebay when you sold them there a few weeks ago. shipping was excellent and the items arrived in perfect shape! the install was easy (i have access to air tools though) and straightforward. the car revs a bit quicker and feels stronger through the whole powerband.

this is a perfect first mod!

Went to my mechanic today to get the underdrive pulley and shifter cable bushings installed.

First impressions of the underdrive pulley, it felt alot lighter then the stock crank pulley. Which was good. Installation was fairly quick about 30-40mins tops.

One problem my mechanic mentioned that he had the push the tension to the max setting which could require a shorter belt in the future if it started making start up noises/squeeks. But none the less he said it was good for now anyway.

Started the car up. No sound issues. Driving impressions were good, it felt abit smoother to get up to speed. The throttle response was abit more revvy, but i did not get to fully test it. So it did not seem like it was a huge difference, but there is definately abit more punch.

Onto the shifter cable bushings, my mechanic installed the fairly easy. Moving it around for the first time after the bushings were installed it felt very stiff, i almost could not move it. Haha, but after a few shifts while the car was sitting, the movement came back. I have the NST Engine Short Shifter and i must say that they work well together. It feels alot more firmer then it was, which makes it alot better to drive now.

Overall i'm pretty satisfied with these products, but i'll have to give the pulley abit more testing :burnrubber: :laugh:

[PetersRedYaris]

Do we have any new NST Pulley owners with user reviews or comments to share?

:burnrubber:

Yes, I just installed the CR lite pulley on my Xb today. I have some positives and negatives.

Positives- I emailed NST to ask about a pulley for the Xb because it was listed as "special order". The good news was they has 2 in stock, a grey one and a red one, so no 5 week wait. I ordered the grey one and received it on monday (1/19).

The materials and workmanship are superb. It spins so smoothly I just had to watch it idle for like a minute. :wub:

Negatives- I see NST has listed the other red pulley they had in stock on ebay for $25 less than what I paid just days earlier. :thumbdown:

I installed it today, everything went great, but the power steeering belt is a bitch to both loosen and tighten.

Now for the wierd stuff. I left my brothers shop following installation of the pulley and drove about six miles on the interstate and began to hear a sort of rhythmic vibration most notable around 3000-3200 RPM's. The noise got quite loud and freaked me out so I took an exit and pulled into a parking lot to inspect. The noise was now audible at all engine speeds and (having opened the hood) was clearly coming from the pulley area. I was now pissed and jumped back in the Xb to go to my brothers shop to swap it back to stock. By the time I got back the noise was almost gone. I even took my brother for a ride so he could hear it, and by the end of that short ride it was completley gone. :iono: I decided to keep it installed and see what happens. 14 miles home, no noise. Then I just drove to work (where I am now) and it was buttery smooth, no noise, and I could definitley feel the extra Zippiness in the lower gears. Anyone experience this following installation of their pulley?

Final negative is the NST pulley weighs 1lb 9.2oz while the stock weighs 3lb 11.3oz, so just a 57% reduction in weight. Not bad, just not as much as many other pulleys they have listed.

Overall I am very happy, just concerned what the noise was and wondering if it will return.

Edit- See post #331 for an explanation of what caused the noise.

Hmmm... very strange. I can honestly say that I have never heard of this (noise) issue. That having been said, I can only speculate as to what the noise may have been...

I would suggest double checking your belts, making sure that they are both routed propely, and that neither was pinched during installation. Also, how many miles do you have on these belts? Belts are wear and tear items, and do need to be replaced from time to time. Again, these are just some things to check... I am not saying this was the cause of the noise.

Otherwise, I would keep an eye on your engine bay to make sure everything is in the right place and working as it should be.

You are more than welcome to take off the pulley and return it to us for inspection, should the noise return.

I am always available via PM, Email, AIM, and of course PHONE.

Thank you again for your interest in our site and products, we certainly do appreciate it. Good luck and have fun with all your future projects!

[PetersRedYaris]

Yeah, it definitely was a noise, I shouldn't have said vibration as I couldn't feel anything or see anything while it was idleing with the hood up. I guess it was more of a rhythmic ringing. Very wierd...:iono:

The belts are origional and have 59,000 miles on them, they looked fine so I reused them. I'm sure the routing is correct and belt tension is on the low side as I would rather have a belt slip than over tighten it.

I can't explain it. It drove home from work perfect as can be. And might I add I got to really feel the difference in acceleration. :burnrubber:

My garage is too full to pull my car in (hence the reason for going to the shop to install it), but if we have a warm day I'm going to pull off the passenger wheel and inspect everything just for peace of mind. And of course should it do it again I'll remove it and send it in for inspection. I just fear it's not the pulley (i don't see how it could be).

Oh and one last negative, it has no NST logo etched on it. I was a bit dissapointed by this. :cry: Just the smooth anodized grey finish...

[bzinn 1]

could be the belt on the new pully........I had a pontiac that i put pullys on and it made a nasty noise the first 5 miles which took me an hour to drive as i pulled over to look for issues every 1000 feet too.......check the alignment of the pully and make sure it is not on to deep or shallow....that was what my first thought was on mine,but ended up being old belt no like the new pully.

[NonStopTuning]

I would suggest using a new set of Gates belts. 59K is a lot of miles for one set of belts, and the belts have surely stretched and aged a bit by now.

Even if they aren't noisy anymore, it would probably be a good idea to replace them. After all, belts are wear and tear items and should be replaced from time to time.

:burnrubber:

[PetersRedYaris]

Well, I'm quite certain I've found the problem, which brings both good and bad news. The good, the NST pulley in no way has caused the problem. The bad, the water pump has some dried antifreeze "crust" below it, indicating a failing water pump. I did some searching on Scionlife and found this.

http://www.scionlife.com/forums/viewtopic.php?t=242265&highlight=water+pump

Watch the video... Wow, a similar noise. Why mine decided to make the noise when it did and then go away is beyond me. Coincidence I guess. And according to the scionlife thread, it seems earily common to have a WP go out at about my mileage.

So, long story short, I'm not replacing it tomorrow as I have found zero fluid under the car after it has been parked and the noise has not returned. I'll get a genuine pump (and some belts I suppose) from Sparks Toyota and keep it ready for when the noise returns or a faster leak developes.

Oh and here are a couple pictures.
Heres the Pink "crust" under the WP-

How much does it weight ?

[CtrlAltDefeat]

I see installing the underdrive pulley means you need to re-tension the belt... how do I do that? and how do I know what the tension is supposed to be?

[NonStopTuning]

The alternator is used as the main source of tension for the belt.
When in doubt... more tension is better than more slop.

:burnrubber:

[jkuchta]

Carefull!!! Too much tension will damage the waterpump!

[Klink10]

I see installing the underdrive pulley means you need to re-tension the belt... how do I do that? and how do I know what the tension is supposed to be?

There was a DIY posted that included a method which I also used. Prior to loosening the alt., mark it with a line using a felt tip at the point where the bolt goes thru the bracket. This way you have a line on the alt. and the bracket. Without smearing the marks in the process, do your replacement and then realign the marks and secure. If you are also putting on the 10% underdrive crank your bolt position will move approx. 1/2 to 3/4 in. As far as tool used to achieve the tension, I used a wrapped prybar placed carefully.

Don't forget to allow for stretch if you are doing a belt change. Your marks will not align and to much tension to get them too will or may cause damage to other parts.

Hope that helps.

Now this is my question.... is there any of those pulleys available for the 1st generation Yaris or Echo (whatever makes you happy)? we have a small crew down in Panama city, Panama very interested on that but we are not sure if we get them, are they going to fit or to work in our engines? 1.3L 2nz-fe

[NonStopTuning]

... and now I've had a few days with a properly working car and I really only have one word for the underdrive pulley...

:eyebulge: WOW! :eyebulge:

It's hard to believe one little upgrade could make such a difference... It revs better, accelerates faster, even sounds nicer, I think. One thing I know, the shift points have moved. With the stock pulley, shifting into 2nd happened at 30mph and shifting into 3rd at 60mph. It's changed to 33-34mph and 63-64mph respectively. And getting to those shift points is much quicker. In stock form hitting 85mph (http://www.youtube.com/watch?v=m8Gbb8WteQg) was like an event. (that's my video btw) Now I find myself pulling it back from 80 all the time... I down shift to pass someone, and suddenly I'm on my way towards 90... To tell the truth, with stock suspension I think it's almost a little scary! :eek: I took my coworkers to lunch yesterday, and thought it was kinda funny to watch their heads snap backwards. :biggrin: I think I'm going to take another 0-85 video when I get a chance and post it here...(maybe after my springs are installed) In closing I must say

NST FTW! :biggrin:

Glad you are enjoying your pulley!!!

Yes, these same pulleys fit the 1.3L. Many international Yaris owners are using these pulleys.

Whats is the diffrence in performance between the light CR and the 10% under light CR pulley.

[NonStopTuning]

Whats is the diffrence in performance between the light CR and the 10% under light CR pulley.

CR-Lite can be used in n/a, turbo, and supercharged applications.

Underdrive Crank Pulley is designed for n/a, and turbo, and will free more power for these applications.

I'd think anodized aluminum would handle it better.

You might wanna check on something else if you are getting salt that far up into your engine compartment though :D

[whiteghetto]

wow, way to much info here.
But I don't think this question has been answered
I can either get the light crank pulley or they 2 pulley set from cali yaris.
what would yeild more benefits?

2007 LB w/CAI. and a small sub amp (about 600 watts)
Will also be getting a rear sway bar, just want to know what pulley to order :)

any help or info is greatly appreciated

I will copy and paste the answer I gave you via Email earlier tonight...



I have a, hopefully, pretty straigtforward question.
I am wanting to know what setup would provide better results in MPG and HP

1) crank light pulley(NST09010)
2) Pulley Combo (NST09025K)

My car in a nutshell
2007 Yaris LB w/auto w/CAI w/600 watt sub amp

thanks for the info :)

John




Hi John,

Thank you for your interest in our site and products, we appreciate it.

The setup that would provide the best results in MPG, HP, TQ, and throttle
response would be one that would provide the MOST weight reduction along with a
small amount of underdriving of the accessories.

So you should consider NST09010 Underdrive Crank Pulley + NST09025K Alternator
and Water Pump Pulley Kit. The more NST pulleys, the better the overall result.

Thanks again, and good luck!

Hold your horses guys!!!

The 1.5L and the 1.3L pulleys are the same as long as they are the same generation Yaris.

For the first generation Yaris (echo) either the 1.5 or the 1.3 you need to look for the Scion xB (first gen) pulleys.

Your cars have a double belt design crank pulley that is not a match with the Yaris pulleys offered by NST.


However, don't feel bad... NST has pulleys for the first gen xB that should fit your cars!:headbang::headbang:

Last I checked, Garm at MicroImageOnline had the NST CR-Lite in stock and ready for immediate shipping. I would suggest checking with him.

We do not build the CR-Lite very often anymore because the majority of our customers prefer the Underdrive Crank Pulley. Compatible with the OEM belt and better performance for n/a or turbo applications.

The ALT & WP Kit includes two pulleys that are the same size as the OEM pulleys they replace. The NST versions are roughly 70% lighter than the OEM pulleys and this weight reduction leads to better throttle response, quicker acceleration, and better MPG.

No one using NST pulleys should be worried about the performance of the a/c, the alternator, the water pump, or any other accessory. We take the performance of all accessories very seriously when doing our research and development. We build products that will provide you with excellent performance gains, while keeping ALL your accessories functionality in tact.

Go with NST and go happy :thumbsup::thumbsup:

You can read through the many pages of this thread, as your questions have been answered many times, in much detail.

Short version...

If you plan to stay naturally aspirated you should use
NST09010 plus NST09025K

If you plan to go supercharged you should use
NST09158 plus NST09025K


We are currently sold out of our crank pulleys (till May 2009), but you should be able to order these pieces from MicroImageOnline.com

Good luck and have fun with all your projects :thumbsup:

I'm not quite sure what type of comment would be warranted here.

Unfortunately we have never tested with any Yaris that did not have a/c. And as far as I can tell, you are our first ever customer to use one of these pulleys on a Yaris that has no a/c.

Based on past experiences with other cars I can see how you may need a slightly shorter belt with your setup and it sounds like you have found your solution.

Buying a new belt is a small price to pay in exchange for picking up a few extra ponies :thumbup:

Any other owners out there running around with no a/c, please feel free to comment.

You're not alone. I'm planning on getting the pullies soon and I don't have AC. I'm glad I popped over to this thread first.

[NonStopTuning]

So I drive pretty spiritedly. I used to get about 35-36 mpg when i used to do a mostly freeway commute. Now because of my new job i drive in stop and go traffic to and from work. And usually get 29-31 depending on how i drive.

I would assume with the NST pulley since it is lighter and less rotational mass one who does more stop and go driving would benefit more from it than someone who does mostly longer consistant speed commute. Since it requires less power from a stop to go than it does to keep at a constant rotational higher speed.

And my last tank jumped to 35mpg. The most i ever got for months. I am hoping its not a fluke as there are many variables. But im awaiting to post my results again the next fuel up. If its the same than the pulley will pay itself of in fuel ecnomy alone especially if gas prices rise. I drive very aggresively so i can imagine if i backed off the throttle a bit i would get even better results. I hit redline on a daily basis.

Installed mine a few weeks ago, certainly can feel a bit more response on the lower end (went with the underdrive pulley). Noticed a bit better fuel mileage than before, not a drastic change or anything of the like, but anything is appreciated!

[gmodder]

Got my set installed Friday...Definetly a nice improvement...Iam also seeing better gas mileage. Engine is just as smooth as before if not better....

As far as the performance. Well my heavy ass 17" wheels are kind of killing that..LMAO..

i was just hoping it could be noted somewhere that a new belt is req'd if you don't have a/c

I'll note this for my store - Do you know the part number of the shorter belt that worked?

[Klinton]

i just finished putting mine in its sweet thanks micro image again for being great

[eii]

I ordered one from garm last week, its coming in a couple of hours. I killed some time by getting off the stock crank pulley manually with no impact wrench and well....I must be the strongest guy on YW cause that has got to be the easiest thing I've done on my car. I literally did it while lying on my back...ha! All the bolts were super easy for me to get off, that or my car didnt come out of the factory with the bolts torqued properly, lol. First time I've really been excited to see the weird UPS delivery guy. I'll post pix soon!

EDIT:

4 hours later ups arrives...then install! I havent gone to bed yet so I was too tire for pix, sorry. Anyways heres what happened when I first got in the car...

First thing I noticed was the idle was almost unoticeable. It felt as if my car wasnt even running. Definitely a lot quieter too, it was scary at first haha. Throttle is more responsive, the shifts are so clean and smooth in my auto. Power increase within the mid range, hrm...need to drive more tomorrow to see more...hehe.

Thanks NST, garm, and chinocharles' diy.

Really, the lite pulley frees up HP from the crank that would otherwise be wasted moving a considerably heavier pulley. Seriously, you could use the stock pulley as a boat anchor (albeit on a very small personal boat, but still you get the idea.) Also a plus on the automatic is it helps resolve "gear hunting" up hills. :thumbsup:

I have JUST the light crank pulley and it made a world of a difference. I had the battery disconnected while I was working on the pulley and some electrical stuff so I guess it took the ECU a couple of day to 'learn' the new revs. Theres a definite increase in power all throughout the power range. I could only imagine the addition of the WP and ALT will increase power even more. Honestly just the difference you feel at idle and shifting is worth it, I just consider the HP a cool bonus. :thumbsup:

The stock pulley is way heavier than the NST one. I was playing with the stock one earlier today and dropped it on my foot...OW..:mad:.

I did notice on my auto sedan when going up a hill it didnt do that stupid gear hunting :thumbup:.

[severous01]

hey, i was thinkin about underdriving but it's seriously not suggested for my camaro as a daily driver. i was wondering what you would say as a economical standpoint on the underdrive. i'm worried about longevity over power...i have a 500hp camaro for power...

any way, i'm going with the alt and wp pullies as well, but dont know about underdriving.

any way, PM or reply here pls.

[scape]

i'm confused here, some are stating smoother idling, and someone in a thread even reported it being dead-quiet..but others are stating rough idles...my guess is the belt tension, but I'm just curious what's up

[bikegerm]

Well after putting them on a chain and wearing them like "bling" for a few weeks, my complete underdrive pulley set was installed today !! Now when I take off from a dead stop I have "Zing" !! There is definitely a difference with initial "launching" and in throttle response when I shift between gears.

Second, I can't believe the difference in pulley weights. When I put a factory pulley in one hand, and a NST "RED" in the other, the weight difference was so significant that you could "guess" that the NST pulley "felt" 40-50 percent lighter. Don't know exact specs, but I do know it's amazing how much lighter they are !!

SHOUT OUT TO MIKE NACARATO :clap:
Went to his house this morning and he had my complete set installed in 90 minutes. He's got all the tools, know how, and passion for what he's doin'. I got to ask questions and torque the water pump pulley while he loosened it! This is what Yarisworld should be about. Fellow members helping each other out for the common coolness of cars!! This just got me more excited for the Import Alliance gathering in July.
ONCE AGAIN, THANKS MIKE !! :bow:

It does however help when I'm on the freeway doing a downhill pull but the the pulley doesn't do much until 4-5k when your almost out of run to do it.

Underdrive pulley does have negative effect on AC. it's the only thing I noticed after installing it. Ac isn't as cold as it used to be but it's something I figured would happen. I'm pretty sure though this lightened pulley will open up horse power for later boost applications though.

Not trying to bash NST or anything btw. I have their SSK and it's frikken sweet! but I just don't think the pulleys are what everyone on the forums hype it up to be.

Hi NST pulley users, I would like to know if you guys have this sign of wear and tear on your WP-lite pulley?

This is typical and happens with all pulleys over time. Nothing to be concerned with, or worry about.

Good luck and have fun with all your projects!

I just have something to ask all the guys that have installed the NST pulleys. I am currently driving a sedan auto. Will installing either underdrive pulley or the lite pulley effect the top speed of my car? I know that it will help in the early pick up but what about the top speed?

Good question.

NST Pulleys do not change the top speed of your Yaris, but they will allow your engine to rev up to speed more quickly, thus reaching your top speed more quickly and with less effort.

NST Pulleys lead to better throttle response, better hp and tq delivery, quicker acceleration, and better fuel economy.

NST PULLEY OWNERS, please feel free to chime in. We would greatly appreciate it!

[severous01]

ok, i'll ask again since noone wants to answer in a week or two...and a PM box is still full.

hey, i was thinkin about underdriving but it's seriously not suggested for my camaro as a daily driver. i was wondering what you would say as a economical standpoint on the underdrive. i'm worried about longevity over power...i have a 500hp camaro for power...i'd rather keep my alt n wp in tact as well as AC. plus i dont want any flickering lights.

any way, i'm going with the alt and wp pullies as well, but dont know about underdriving.

any way, PM or reply here pls.

so anyone with any long-life problems underdriving other than a weak AC? like, lights flickering or low charge on battery...overheating engine or higher temps???

First, thank you for your interest in our site and products, we appreciate it.

Second, then answers to all your questions are here in this thread.

So I will try to give you the short version here...

1. Underdriving on certain applications is not recommended. Furthermore, the older, more traditional pulley kits out there used to underdrive the accessories by a very large amount... ie. 40%-50%. Especially on muscle cars, where the majority of owners were thought to be purchasing such kits for RACE applications, not street. Even the majority of the older kits that were made to cater to Japanese imports were built this way.

2. NST stepped into the picture in 2005 with the understanding that the majority of our customers who are modifying small imports these days, are doing so with their daily driven cars. Our Underdrive Crank Pulley for the Yaris underdrives the accessories by only 10%. NOT enough to cause any premature problems with any of the accessories, but enough to provide a few extra ponies to drive the wheels.

Again, MUCH of this info, and a whole lot more, is provided throughout this thread.

Furthermore, we have THOUSANDS of happy customers on the following forums...

www.YarisWorld.com
www.ScionLife.com
www.8thCivic.com
www.Club4AG.com
www.MicroImageOnline.com
www.86Garage.com
etc etc etc


THOUSANDS of user reviews when it comes to NST Pulleys, 99.99999% of them positive.

The horror stories that applied to our grandfathers' pulley kits do not apply to NST pulleys.
Not all pulleys are created equal, and NO OTHER pulley is an NST pulley.

Good luck and have fun with all your projects!

I read on this thread that installing the pulleys your a\c will not work as good. How much of a difference will i notice.

[mikenacarato]

i didnt notice any difference. pulleys have been on for a few months now with nothing but good results. i also have the underdrive set and a system installed in the car and have never once had any slight electrical issue with it being underdriven.

dont think....just do....do nst pulleys today!

There are SEVERAL reasons, with one major reason being cost.

Toyota also does not offer high performance camshafts, exhaust systems, suspensions, turbo or supercharger kits, etc.

Just because Toyota does not offer these pulleys does not mean that you should shy away from them.

[dallas]

McDonalds has thousands of happy customers too, but does it mean your eating healthy LOL. :biggrin:

I believe the reason why they are not fitted at the OEM level has to do with harmonic vibration control, something a solid pully does not do as well. The Society of Automotive engineers has some good papers on this subject. Correct me if I'm wrong but I'm not aware of one O.E.M manufacturer using a solid aluminium crank pully. With car companies under pressure to meet Corporate average fuel economy requirements, if all the benefits out weighed the negatives you would see them on all cars.

Now if your willing to accept some negatives like the ones mentioned by others, the car will pull noticably harder with a underdrive pulley, It feels rev happy. On other applications I have used underdrive pulleys for over 50,000 miles with no engine failures. Just like any performance mod, there is always some offs.

To dallas - you can decide to get it or not, its up to you, but when Mike says we have positive feedback on the pulleys (all 3), he means it. There is a member on here w/ NST pulleys on his Yaris sedan, and he has over 330k miles on his car...Has he reported a problem on his Yaris in terms of the pulleys failing on him after all those miles? NO

Here is the thread of the member, plus his video w/ exhaust, header, intake, AND under-drive pulleys..http://www.yarisworld.com/forums/showthread.php?t=16416&page=2

So please take it into consideration what Mike has to say about his products. He isnt sounding conceited either~

I'm one of the few worried members putting on aftermarket parts on the car, as I pay for everything myself, and i dont need any additional expenses coming my way in this horrific economy....

In todays times, the only real statistics that hold up are those of actual peoples w/ the product....not paper printing out data~

do they void the warranty?

[Astroman]

No, unless toyota can prove that the part has caused the malfunction, or you damage something when you do the install (had a professional mechanic friend do my install.) I'm well past the factory warranty, but when I was I had warranty and non-warranty work done and they never said anything. To date there hasn't been a single malfunction in any yaris with NST pulleys.

You will get increased engine response, weight reduction, mpg increase of about 1-3mpg, insane decrease in the auto with "gear hunting", awesome customer service, and better 1/4 mile times.

This has been my experience anyway. :burnrubber:

my friend is a toyota mechanic and he was replacing a blown motor on a toyota yaris and they sourced a motor from a salvage yard. the motor they brought into the shop had these pulleys on it and they installed the motor into the customers car without the pulleys.


my friend whom is a toyota mechanic didn't seem to think there would be any problem with the scrapes and scuffs, but i'm just getting a second opinion.

The Underdrive Crank Pulley is our most popular. This pulley, combined with the Alt & WP kit, offers the BEST all around performance and fuel economy for any manual or auto Yaris... n/a or turbocharged.

The CR-Lite Crank Pulley is the way to go for supercharged owners.

Reading through the many pages of this thread will explain these concepts further.

I just ordered my pulleys this morning, the underdrive crank pulley and the other two. I read this entire thread over the last couple of evenings and the feedback cannot be ignored :-) I decided to go with the gray ones, so they aren't that obvious in case someone takes a peek at my engine. In California they are not legal unless they have a C.A.R.B. E.O., if I understand this correctly. But oh well, how can improved HP and gas mileage be bad for you or the environment? :-) Having said that, I can't wait!

The Short Shift Kit and the shifting bushings are also on the list :-)

Mike,

I got a question for you, how hard/tricky is to install the pulleys for a typical DIY enthusiast? What I am most concerned about is to get things like belt tension correctly after I'm done and not break anything in the process :-)

I've installed a Radio/CD/MP3 player, towing hitch, electrical towing harness on my Yaris so far and I'm installing a cold air intake this weekend. But the pulleys seem to be by far the most "advanced" project - kinda pushing the limit of my comfort level. But on the other hand I want to do it myself, so I can bragg about it later ;-) What are your thoughts? If I get stuck, the auto shop is right around the corner I can push the Yaris over there ;-)

Oh and I got the rear windows plus trunk window tinted today... sweet! The ICW Racing wheels have been ordered and expected to arrive some time next week, yeah baby! :-)

[NonStopTuning]

fmicle,

Thank you for your interest in our site and products, we certainly do appreciate it.

NST Pulleys DO NOT change the engine's breathing or exhaust system, and
therefore do not change the air fuel ratio, nor the ECU's engine control
characteristics/programs.

Due to these reasons, there are no CARB or "smog" issues to worry about. As a result, no CARB sticker is necessary. DO NOT let anyone tell you otherwise.


Installation is not very difficult, and there are a couple good DIY installation guides on YW. The most difficult part of the process is breaking loose the crank pulley bolt, the one bolt that holds this pulley in place. You should be able to break it loose with the proper tools and will need a torque wrench to reinstall your bolt back to roughly 120lb ft torque.

Your belt tensioner is an automatic piece, which will make belt installation a breeze. Just install the NST pulleys, install your OEM belt, and tighten everything up.

Having said all of this, we recommend that everyone seek the assistance of a trained professional if they are at all uneasy or concerned about proper installation. NST pulleys have been proven to work time and time again, and we can not be held responsible for any damage caused by improper installation or any accidental damage during the install process.

Thanks again, good luck and have fun with all your projects!

:burnrubber:

[fmicle]

Alright, I just finished installing the underdrive crank pulley and the water pump pulley. I must say, I was afraid I was going to have difficulties with the crank pulley bolt, but it came off easily for me. Tightening it back together was a whole different story though :-) I was lucky that my neighbor came home as I was struggling and trying to figure out a way to prevent the damn pulley from turning, so I improvised with a rope and he held onto it, so I could torque it up to spec.

The water pump pulley was a bitch... Much more difficult to install than the crank pulley in my opinion, because it's much harder to get to. Anyway the 3 screws don't need that much torque though, so I managed again with the rope setup by myself.

Since I got the underdrive pulley, the mark I had made on the alternator support groove was useless, and I had to pull the alternator farther toward the front of the car to take the slack from the belt. After I tightened the bolt I felt it with my hand and it didn't feel as tight as before... But I took a test drive and everything seems good. I will admit that I didn't feel much of a difference, maybe because it's late and I'm tired or because I had my expectations a little too high... nevertheless I am happy, I thought it felt a little zippier on the freeway though... but it could all be in my head :-)

Unfortunately, I didn't get to install the alternator pulley, since I don't have the right tools. That seems to be a little tricky, it looks like I need 2 wrenches at the same time, one to hold onto the axle and the other to unscrew the nut.

Anyway, if anyone has a few words of wisdom regarding the driving belt, it will surely be appreciated.

I even turned on the AC on my test drive and everything was fine, no squeaking or funny noises. I remember my previous car (1998 Jeep Cherokee) used to squeak like hell when the engine was cold if I had the AC on (and I always thought the driving belt was a little loose, but was too lazy to get it fixed).

[lilredrocket]

Hey I just did my first auto-x with my u-drive pully yesterday and leaving it in second gear was great the car actually responded when I punched it in the lower RPM range. Thank you for the great product Mike!!! NST FTW!!!

Got a pulley set from Garm the other day. Great quality. Very light. Put them in today. Couldnt feel a difference. Must be better for manual transmissions. Will have to drive the car a bit harder.

[AznGouki]

Can you explain why the CR Lite pulley is better suited for supercharged cars? Like will there be a issue if I use that pulley? I plan on getting a supercharger down the road and I don't want 2 pullies. If you could explain the difference between the CR Lite and the Underdrive, I think I can finally make a decision haha. Also I believe I read that the underdrive pulley is smaller than stock and since I have no A/C I will have to get a shorter belt. Is the CR Lite pulley the same diameter as stock?

Also I believe I read that the underdrive pulley is smaller than stock and since I have no A/C I will have to get a shorter belt. Is the CR Lite pulley the same diameter as stock?

The underdrive pulley is a little smaller, so it ends up spinning the water pump, alternator, A/C compressor, etc a bit slower (10% in the case of NST underdrive crank pulley). This is enough to free up a little bit of power and at the same time not affect the other functions. Unless your stereo or some other electrical app requires a lot of power, you won't feel the difference just because the pulleys are spinning a little slower. It's like changing your driving style to 10% less rpm...

The basic idea is that smaller and lighter needs less energy to spin (accelerating and decelerating), so your engine will feel more responsive.

You don't need a shorter belt, you just need to adjust the alternator on the groove, pull it a little to take the slack out of the belt after you install the pulley. At least that's what I did on mine and so far it's been working fine.

[AznGouki]

Fmicle do you have A/C? I think it's Barber that has the underdrive installed and had to change his belt. Would there be a draw back if I use the CR Lite w/o a supercharger? I would imagine not since I'm thinking all it is, is a pulley that is significantly lighter.

[NonStopTuning]

The NST Underdrive Crank Pulley is intended for n/a or turbo applications. This pulley should not be used with a supercharger because it would lower PSI on such an application.

You can use the NST CR-Lite on n/a, turbo, or SC applications.

You can use the CR-Lite now and keep it installed once you install your supercharger.

Yes, I do have A/C and just got back from a trip to L.A. (from San Jose), and I had the A/C on 90% of the time. I must add that the car performed excellently, exceeding my expectations in terms of acceleration and speed. And the gas mileage I got on the way there blew me away. I will refuel on Tuesday and post my results to this thread.

I wouldn't call it a "drawback", it's an improvement either way, it's just a slightly better improvement with the underdrive than with the "lite", if my understanding is correct.

All I can say is WOW...NST CR Lite Pulley

So I incorrectly thought my car was quite quick with the mods that I had installed, but after taking it out today for the first time with the NST CR-Lite pulley, I have to say I was sorely mistaken...

Now it's FAST... (O.K. excluding Garm...)

The crank pulley absolutely has changed everything...

The feeling that revving up first gear is going to blow up my engine is gone...It revs up nicely, and allows more time to prepare for second gear, which I felt was a trouble spot off the line before the pulley install...

Above 4000 RPM up to redline is just so much stronger, and more importantly smooth and effortless...The car is just nuts (my face literally switches between this and this ) now at 5-6000 RPM...

I'm actually glad I did this after all of my other mods; I didn't think there would be as much noticeable difference as compared to the postive feedback given by relatively stock guys doing this swap...

Cheers

Well, this is a lot to try and sort through. Guess I'll just ask anyway: what is the potential downside (if any) to using the underdrive version rather than the CR Lite?

Just ordered, updates when received and installed.

Took almost exactly 45 minutes with electric impact ratchet. Had a friend throw it in 5th and hold the brakes while I torqued her down (actually had to jack the car up higher just to get the clearance and a proper angle for the torque wrench).

Noticed a slight difference in revs and a very noticeable difference while passing in 3rd. Made the investment for fuel economy more than anything (my daily commute is 35 miles of mixed driving with a heavy foot, getting 35 +/-2 mpg now. If the results impress me at the pump, I might consider the Alt and WP pulley.

Anyone have anything to comment on upgrading from solely crank pulley to the combined 3?

Yup. Got my u-drive pulley installed on Friday, and I think it was closer to 30 mins, but maybe 45. I was excited! Same thing; had to jack the car up a bit more to get really good torque leverage. Its about as easy as anything you do on a car. The impact wrench makes it easy. Hardest thing is loosening the alternator lower-bolt.

Love the improved response and definitely better power in mid-gears. Not a huge increase, nut definitely noticeable from the get-go. I think driving on the regular commute route will reveal more as I approach the same roads I drive every day. No argument about the bang-for-the-buck argument; it is worth it.

Told you these pulleys rock!!!

Told you these pulleys rock!!!
Yeah I thought that would be a good idea, so that in combo with a cai, and good exauhst it should make a reasonable bit of difference.:w00t:

My next purchase is the larger sway bar from micro or NST if I can get a hold of them.:burnrubber:

[NonStopTuning]

Any new NST Pulley owners out there?!

Just got my Used Grey NST CR Lite Crank Pulley from tk-421. Thanks Bernie. It's in as new condition. I've done a bit of a search but I can't find a DIY for install. Is there one? I'm not even going to try to install this myself as i'm not mechanically minded, but i'd like to see how it's done and I have friends who are mechanically minded who could do it with instructions.

If there is no DIY how long would it take a mechanic to intall one?

I've been quoted $90 an hour labour and been told it may take an hour-an hour and a half!

Thanks for the info. Why would the DIY op delete his thread?

Because he decided that he no longer wishes to be part of YW.
