Let the fun begin....

[largeorangefont]

My pulley is still on the workbench. :frown: I haven't had time to put it on.

[absenter]

I'll be makin an order soon. Did you guyses already do a GB?

[Galavoxx]

I just installed mine today. Feels great!! Butt dyno says Yes!!! :burnrubber:

I'll refrain from ranting and raving about these again... just know that if you don't have one yet, you're missing out.

[absenter]

Dude! Give me two weeks. I already blew my paycheck on fogs and a bunch of other stuff. Oh...my car note? Yeah, I guess it would be pointless to buy stuff with for the car and not the car itself. Hopefully I'll be ranting and raving soon. :headbang:

I had mine installed recently and I love it. Big increase in throttle response. Best $100 mod I can think of:burnrubber:

[RogueYaris]

Damn Chino, you're bumping this thread like it were Paris herself.

I am interested in hearing more personal experience from others about this. I'm very tempted to get one.

[hasher22]

Just get one...its cheap, plus if they say what it does then its worth it.

Im gettin one soon......just need to tell him to invoice my paypal.

[evilreign]

This is definately well worth it. I've got it on my car and the biggest difference I noticed was a much better throttle response also. Highly recommend this mod to anyone who hasn't done pulleys yet.

[Galavoxx]

Having driven the car for a few days now, here's a little update.

The good: I'm still lovin' the NST pulley. Couldn't be happier. Mid-range really is much more punchy. Feels like more than 5 hp but who knows. All I know is that it revs much faster and seems to pull harder. I can't wait for the other pulleys!!

Other than the increased performance, the car idles a little rough, especially when warming up. Even after it's warm I can definitely feel the engine vibrating more than before. This is only at idle.

I have the five speed and I've noticed that takeoff requires a little more clutch than it used to. However, once rolling, accelleration is smoother than before. The last thing is that the car doesn't want to creep as easily at low speeds which sucks in traffic. Buuutt.... accellerating away from the toll booth is a blast!!! :burnrubber: Anyway, my 2 cents.

[PetersRedYaris]

The extra clutch is required as a decrease in rotating mass equals a decrease in torque. Should be better engine braking though. Wonder what it feels like on an automatic?

[PetersRedYaris]

Question: Some new vehicles require a new crank pulley bolt if it has been removed, sort of like a one time use head bolt, because they stretch and are considered a one time use item. Is this true with the Yaris? If the crank bolt worked it's way loose because it was reused when it wasn't supposed to be that would be bad.

I'm going to talk to a service guy I know down at our Toyota dealer and see what his take is on this mod.

[Galavoxx]

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

[Astroman]

As far as using a new bolt on the crank pulley, I didn't need a new one. My mechanic installed it for me (he had the air tools and hoist) and I haven't had a single issue. As for the engine braking in the auto, I haven't really noticed a big difference. I have been trying to use DFCO as much as I can in town, but this was after I got the pulley installed. Can't really say it changed much at all. Also the local drag strip opened up and has a schedule now, I am going to get my Yaris (after CAI) and LeBaron turbo out there and have some numbers soon. :headbang:

I put red loctite on mine. I pity the fool who has to remove it. Probably end up being me... :rolleyes:

[ChinoCharles]

Yeah, I used the blue loctite... just in case it ever does have to come off. :laugh:

[PetersRedYaris]

That red is too strong in my opinion. I always use the blue medium strength and still think it's tough to get bolts undone somtimes.

No. The old Yaris has a 2 belt pulley, from what I understand. You may be able to use a Scion pulley. Ask the Scion guys over on Scionlife.com.

[Doc Zaius]

Hey NST or Chino... are there any plans on making an A/C pulley as well? Heck, I'm not even sure if its replaceable..!

[ChinoCharles]

No, because anyone that wants horsepower that badly can just remove that pulley and get a shorter belt. :biggrin:


No, honestly there are no plans as of yet, but as long as we keep supporting NST... NST will keep supporting us. Never know.

[NonStopTuning]

Hey NST or Chino... are there any plans on making an A/C pulley as well? Heck, I'm not even sure if its replaceable..!

Very good question Doc!

Chino gave you a very good answer there, but I will take it one step further for you. The A/C pulley on most Toyotas is a "clutch-type" pulley. This clutch engages from time to time in order to start your compressor. Building a lightweight version of this type is very difficult and very expensive. And to be honest with you, the gains would not be worth the cost. Those building track cars would rather eliminate the A/C unit.


Other Updates:

We are currently working on a few things for you guys. Some of these are new alternator and water pump pulleys. Keep an eye on our site for a summer release.


Last but not least... Contrary to popular belief, supply of aftermarket products relies much more on the DEMAND side rather than the supply side! And demand does not mean you guys posting on forums and saying "build stuff for us!" Demand means you guys supporting the aftermarket companies that are willing to cater to your needs, build and test quality products, and offering you a great value. The more you support these companies by actually USING their current products, the more they will be willing to build you other products in the future.

Having said all of this, I want to thank all of you who have supported us thus far. I promise you that if you keep supporting us, I will keep working very hard to design, test, and bring new products to the market for you guys.

[Doc Zaius]

Thanks for the answer Mike (and Chino!) re: A/C pulley. :thumbsup:

And with regards to demand driving the aftermarket support, now that its warm out I'm very much looking forward to installing my cherry red NST crank pulley. Just wanna get it on the dyno first for a stock run. AANNNDDD I can't wait for the other pulleys to be released this summer... I'll be in that group buy too! :biggrin:

[sdmf]

well i got a crank pulley from another member on the forum, havent put it on since there are more nst goodies on the way. :) but i would like to know if nst would be making a flywheel anytime soon? am i just dreaming or is it in the process, chino? nst?

[Black Yaris]

Will there be plans for a pulley package? Would it be benificail to wait for the pkg or should I just snag the crank pulley now?

And do you Anodize in Black, if not can you send me one not anodize, and I can get it done here locally

[Astroman]

I would say to anyone who really wants the Crank pulley to get it now. It is well worth it, and the money you give them helps fund R&D for future parts for our cars. NST prices are extremely competitive. Also, I noticed a bump up in my MPG, so you can start saving gas money as soon as you install. :biggrin:

And do you Anodize in Black, if not can you send me one not anodize, and I can get it done here locally

At this time we offer these pulleys in Red, Blue, and Graphite Gray. I high suggest staying away from pulleys that are not anodized, as this is a very important part of the building process.


:) but i would like to know if nst would be making a flywheel anytime soon? am i just dreaming or is it in the process, chino? nst?

Unfortunately there are no plans for a flywheel at the moment, but we have a few other goodies coming your way very soon, so stay tuned :thumbsup:


Thanks again everyone for your great interest and support, we certainly do appreciate it.

[Black Yaris]

The only reason I would want one NOT anodized is so that I can get it anodized in the color I want, since you do not offer black, and I have a guy that does it here in town for me

[NonStopTuning]

Well, I just figured my gas mileage with the NST pulley and using DFCO. With 100% in town driving, I filled up with just over 10 gallons and achieved 31.68mpg. This is the best mileage I have recorded. This was up from 28mpg the last time I filled up.

Sounds very good sir! This type of MPG gain should be typical for most Yaris owners provided they don't go WOT all day. It becomes though with the extra throttle response though :biggrin:

Do we have any other owners with similar results?

:burnrubber:

Im gonna install my pulley now....

wish me luck!!

[YarisGuy]

So it works for both the 1.5 and the 1.3! This thing just keeps getting better and better :biggrin:

[largeorangefont]

I installed my pulley today. Nice little bump in power.

I got a check engine light the first time I turned on the car. I think this was because I turned the engine over with the ratchet while the key was in the ON position BEFORE I started the car. I scanned the code and is was for a crank position sensor malfunction. I cleared the code and the check engine light has not come back on.

Just throwing this out there in case anyone else has this problem. Just clear the code and you should be fine.

Is your Yaris a New generation or old like the echo Hb??

I am very interested about this information becasue my car is a 1.3L 2nd generation (like the one on the signature)

Other thing is that my country is very hot so we always use air conditioner
if i get to install the pulley...will it affect in any way?

Thanks in advance

[Ran Kizama]

The plan is for 2 more pulleys to come this summer.I think I'll wait and do them all at once then. :smile:

[Astroman]

Yeah, you could do that... But buying the CR pulley now helps fund R&D which will get the rest of the pulleys out sooner. You would also save some gas if you bought one now, my MPG improved 1-3. It would probably be more convenient though to get it all done at once. Regardless if you wait for the whole set or get it piece by piece, your going to really enjoy the results
:burnrubber:

[YarisGuy]

I have the NST CR-Lite and could not be more happy with it. Better response and better MPG.

NST FTW! All other copy cats FTL! :respekt:

Even after it's warm I can definitely feel the engine vibrating more than before. This is only at idle.

If I remember correctly, the manual says not to warm up the car, just take it easy till the light dissapears

[Ran Kizama]

I've heard mention of a harmonic balancer when it comes to pulleys. Anyone care to enlighten me as to if the pulley needs one or not?

[eTiMaGo]

well, after now having the thing in 24 hours, I can feel a few differences from before... For one, the engine does feel more responsive, looser, easier to rev up. How can I tell? My ger-changing timing's all off and jerky now, the engine gets up to speed faster, so I'm over-revving by the time I engage the clutch the "old" way. Should take a couple of days to get adjusted.

Although, at low speeds, the engine is a little more shaky, the advantage of a havier pulley and/or flywheel is more inertia, allowing the engine to spin more smoothly... But, that's also just a matter of getting used to it.

Over all, :thumbsup:

[AlphaFox]

I like mine, but yes it does idle rougher sometimes when the rpms drop under 600. overall im happy with it, definatley more power throught the entire rpm range. funny thing is I really notice it when im engine breaking, it definately helps stop faster!

[Terrorize]

Yeah...i feel the same benefits in mine...
However my mechanic was telling me what i might experience after changing the pulley...and he did mention that there might be more vibration now...and there is a bit like you guys mentioned..but nothing i can't get used to..
he said its due to a lighter pulley...plus the OEM pulley had some kinda or rubber gasket on it to help dampen the vibration?

[Astroman]

No such rubber on the OEM pulley. I saved my old one and inspected. All metal & paint.

[curik]

Mike, your link to the DIY installation is dead? Also when will you be releasing the pulley kit (WP and Alternator pulleys) ? I'm interested.

[largeorangefont]

No such rubber on the OEM pulley. I saved my old one and inspected. All metal & paint.

Mine has a rubber ring between the hub and the grooved pulley ring. Most OEM pulleys do. Check yours again and you will see it, and feel it.

[tk-421]

Do you think it might be possible to swap that ring with the new pulley? Would the NST still fit? Or maybe NST would like to add a rubber ring for an extra buck or two?

[curik]

Mike, I saw another pulley kit with the wp and alternator pulleys. When will these be available?

[largeorangefont]

Do you think it might be possible to swap that ring with the new pulley? Would the NST still fit? Or maybe NST would like to add a rubber ring for an extra buck or two?

No you cant swap it out. Adding a vibration dampner to the NST would probably double its price, and add weight. Slight increase in vibration is the nature of the beast with a light, solid pulley. It was barely noticeable on my car.

[YarisGuy]

A lot of these questions where brought up in the original GB thread when we all signed up for these pulleys. The vibration damper in the stock pulley is a think rubber band that hardly does much. After talking with Mike of NST on his screen name (NSTonAIM) it sounds like NST is capable of building pulleys with these rubber pieces in them, but the costs would be 3 times what they are now. The rubber is very over rated and NST has removed it in 99% of the cars they build pulleys for. The rubber has not proven to be a necessary component of the pulley in all their testing and the testimonial of thousands of aftermarket pulley users for the past 15 years or so.

I don't mind having a bit more vibration in the car, especially with the obvious advantages that a crank pulley brings to the table. I guess I just don't understand why a rubber band would increase prices so dramatically.

Well, I would guess a pulley is being made in a two step process (CNC mill, then anodize), but if you want a rubber insert, it would be made in a lot more steps, as two pieces of aluminium need to be made, then a piece of rubber needs to be made, and sandwiched between the aluminium. All these extra steps would need more time, and a lot more labor, and as a result, a lot more money :wink:

Thanks eTiMaGo, you pretty much nailed that one on the head.

Furthermore on the topic of the rubber damper, engine vibrations, or possible threats resulting from elimination of this rubber piece...

On a relatively understressed near stock motor with bolt ons or low amounts of boost like what most of the people on this forum probably run, a solid pulley will not have any life threatening consiquences. The factory pulley with a 2mm (less than a 1/8th inch) damper is primarily there for wide band NVH (noise vibration harshness) supression from the engine and driveline. Removing the damper and replacing it with a solid pulley will lead to minor addtional NVH but will not harm the engine. In fact, most people claim their engines seem to run smoother with NST pulleys.

The engineering reasons are that most modern engines have a short, strong crank with, a relatively high natural frequency. The dangerous second harmonic that can cause damage occurs at an rpm that this sort of engine will never see, in the area above 10,000 rpm. Even the stock damper is not tuned for attinuation at this sort of rpm so the argument is somewhat of a moot point.

Now small engines that are pushing the limit with lots of revs, wimpy cranks, super long strokes, lots of boost and dwelling in the upper rpm ranges for long periods of time can benefit from a damper designed to deal with this sort of operation but our engine is not like this, and probably very few people with this motor on this forum push the envelope that hard. How many 1.5Liter, 400HP, 11,000RPM Yaris motors do we have on these forums?

As far as I can tell, our engine has a strong and stiff bottom end that is well built for our intended use. It has an internaly balanced crankshaft which is less like to break due to torsional vibration.

There are a lot of Nissan guys who use underdrive crank pulleys in road racing series like NASA or SCCA. Road racing is much more punishing on an engine than other motorsports. The engine is subjected to run times lasting 23 to 45 minutes with the engine always in the upper ranges of its rpm limit. One race weekend is the equivlent of hundreds of 1/4 mile passes.

NST sponsors the first ever wheel to wheel Scion tC NASA Road Race car. This car has been using underdrive pulleys from NST with great results since day one.

NST also sponsors two drift cars participating in the professional US drift series, Fromula Drift. Both of these cars have been using NST pulleys with no issues of any kind for the past few seasons.

We could go on and on...

Is a solid crank pulley harmless to all engines? No it is not. Small, super high reving engines, when modified way past the simple bolt on stages may have problems. These engines reach critcal harmonics, past the 10,000 rpm range, an rpm often reached by certain race engines.

A mildly modded inline six will most likely be fine but one subjected to high rpm for long periods of time (90% of its life) with lots of boost will probably suffer. In this case , the stock balancer/damper is probably not adequate either.

Some of the older american V8 engines are externaly balanced and it is critical not to use a solid hub pulley not designed for these applications, or damage to the engine could result.

Our engines and most around here do not fall into the above catagories. Rest assured that your engines will not blow up and die or have a reduced life in street and even racing use with these parts.

I would bet that every "expert" that tells you otherwise has little personal, practical, real world experience with the subject.

[Vanderkitten]

I high suggest staying away from pulleys that are not anodized, as this is a very important part of the building process.


I prefer the look of anodized pulleys, but it has nothing to do with the "building" process, it's a finishing and largely cosmetic step.

**Step 1: RE-draw the stock pulley in CAD or Solid Works
Step 2: Machine out of solid block of 6061 Aluminum
Step 3: Put on car and test- If OK repeat 1,2 and go to 4
Step 4: Anodize so it looks pretty for a while!

Step 5: Sell the $hiT out of these because it is the best bang for the buck!!

**Note, this is MY patent RandD process... :bellyroll:

I'm still running my stock pully even though you-know-who gave me a free one. Ebayed it weeks ago (I'm not a gambling person)... Lost money/time and got NOTHING. :thumbdown:

[Doc Zaius]

You know, something mentioned on the ScionLife thread that I never thought about: how do aluminum pulleys stand up to extreme temperature variations? Up here in Ottawa, we have anything from -30C to +35C in a typical year (-22F to 95F). I know that cast iron is used for piano frames b/c they don't expand/contract much with temperature. If aluminum expands or contracts a lot, how will that affect the pulley performance, and will it put a lot of stress on the pulley itself...?

I'm an NST man all the way but you also have to wonder how much of that is installer error. Maybe the belts were way too tight or the pulley bolt was over torqued. That just looks nasty.

[ChinoCharles]

You have to remember, it is a part that may be spinning at thousands of RPM's when it fails, turning it into a bonafide Dreidel of ultimate despair! I'll bet the side of his block is all jacked up too!

Not a part to skimp on if you ask me.

[tk-421]

OK... I guess I'm convinced. Now all I need to know is wether I should wait for the pulley set to come out or not. Sure, I understand that it's better to support our vendors ASAP so they can come out with products sooner and allathat, but I'm kinda wary about messing with the motor too many times.
I would much rather install the whole set once and be done with it.

[NonStopTuning]

Hi again everyone,

Wow, it looks like there has been a lot of good discussion here lately. This is turning into a very productive thread with some great information.

Here is a little info regarding fitment on the 1.5, 1.3, Yaris, Corolla, etc. There are two versions of the 1NZ crank pulley...

One version, on cars with NO power steering pulley, is a SINGLE-ROW Crank Pulley.
Example: USDM Toyota Yaris 1NZFE... Just one row there...
http://www.nonstoptuning.com/images/NSTtoyYARIS/NST09158RBG.JPG

Another version, on cars equipped with a power steering pulley, is a TWO-ROW Crank Pulley.
Example: Scion xA and xB 1NZFE... See the two rows there?
http://www.nonstoptuning.com/images/NST04180%20pulley%20PICS/NST04180KG.JPG


Those of you with a USDM Yaris, and those internationally who have SINGLE-ROW Crank Pulleys can order pulleys from our Yaris page on our site...

Those of you internationally, and those with TWO-ROW Crank Pulleys can order pulleys from our Scion xA page on our site...

Installed mine last weekend, got a little over 200 miles on it now. Like others have said, faster, smoother acceleration, a good bit more bite in the bottom of 2nd gear, also much smaller "hole" in the top of 2nd/3rd. GREAT $100 mod--looking forward to NST releasing the rest of the set.

About the torque thing though--earlier post said less rotating mass means less torque, but it feels like more... How does less force to get the thing spinning affect torque? Or am I just confused about how torque works? Only explanations I can find online have too many mathematical equations... :confused::iono::confused:

Thanks for the kind words! Your experience only adds to what others have been saying up to this point, and we are happy to hear more positive feedback.

And regarding your torque question, take a look at some of our dyno testing we have done on different applications. You can see that the entire power band has been shifted up at every point in the RPM band. NST kits provide more HP and more TQ at every point you look at. Less rotating mass on the engine itself will always lead to such results...

I am confused now, don't all new yaris have the same crank pulley regardless of it is USDM or AUDM or JDM model? I can't check what the Thai built yaris has single or double row crank pulley yet as I am still in Australia. Anyone can clear it out? Thanks

[ChinoCharles]

gaffo, research ZPI thoroughly.

curik, the reason for the confusion is that we are referring to different engines in different countries. In Europe, for example, there are 1.0L, 1.3L, and 1.5L Yarii. The NST crank pulley only works for the 1.3 and 1.5.

http://www.nonstoptuning.com/infoPageLite.htm

[curik]

Sorry if this is a basic knowledge. Is that the Water pump pulley? If it is then it must weighs a lot, and upgrading it to NST means a significant reduction?

http://i15.photobucket.com/albums/a400/curik/Picture004.jpg

[ChinoCharles]

curik,

That is the a/c compressor pulley. The water and alternator pulleys are located just above it. It certainly does weigh a lot. Other than the crank pulley that is the largest pulley on the 1NZ. If you are planning on tracking the car, the solution that would bring the highest power gain would be to outfit your engine with NST pulleys, find the proper size belt and bypass the a/c compressor altogether. For track purposes it is only leeching your power. Swapping the belt out would only take a matter of minutes, and the benefits of not running your a/c compressor when racing are very tangible. You will feel a difference.

[curik]

Thanks for the excellent explanations Chino! Since the A/C pulley looks massive, why doesn't NST make a replacement for it as well? I mean, it looks more parasitic than the WP or ALT pulleys together.

[cali yaris]

correct me if I'm wrong, but the A/C pulley is on a clutch that is directed by the ECU when to turn "on" and "off"? I think this makes it problematic to re-engineer for aftermarket use.

[Astroman]

You're not wrong, but NST has already said they are not making a A/C pulley. The pulley set will be for the alternator & water pump. Their post is on here somewhere about it. :rolleyes:

[OxyG3nE]

ive not seen a lot of performance car with A/C ... lol

[YarisGuy]

Track only race cars do not have a/c systems at all. And like others have said, if you want to build yourself a hardcore street car you will eventually end up taking your a/c out to save a few pounds of dead weight.

I have the NST crank pulley now and I'm anxiously waiting to get the alternator and water pump pulleys later this summer. I don't think I could ever go without my a/c during the summer heat!

[curik]

We are going off topic slightly here, I was wondering if there are issues for making a lightweight A/C pulley that make it not possible to do. It looks like the 2nd heaviest pulley in the whole system and why doesn't NST consider making it at all?

[Sabretooth]

I want my A/C to blow a whole 2mph faster on max AC speeds!!!

I demand Lighweight A/C pully now!

Actually I dont see why not, it would just mean more $$ in the bank for NST!!
I would buy, but the point is not to use A/C while in High Performance use.

[curik]

I agree with you Sabretooth, but sometimes we want to maximize performance with the least sacrifice in comfort. So if NST makes the A/C pulley, putting a whole pulley kit on a completely stock yaris will be a significant addition in performance and fuel economy. However there will always be trade off like increase in vibration, but this is minor and I am sure it is worth the trade off.

[OxyG3nE]

:barf:

I don't think comparing any board member to a company that has been around for several years is correct. But since you did it, be it directly or indirectly, I will do a comparison of my own.

1) Last time I checked Charles did not take any member's money to build this intake. He tried it on his own dime.

2) ZPI is a company that "builds" products and was paid by members here who ordered a product that should have been tested extensively prior to being released. What did these members get? Products that did not fit, despite returns and adjustments.

3) ZPI does not have any dynos for their products either. And they have no solid record of doing anything productive for YW. Last we heard was that they were ignoring customer e-mails.

ChinoCharles has many posts and threads in which he has done 100X more for this community by spreading knowlege, giving others ideas and assistance. More than almost any company that has come to these forums.

CC has put up a DIY for the crank pulley, he has had at least some sort of hand in getting NST to build new pulleys. He even helped get the ball rolling on a new SSK.

Meanwhile, ZPI has been hiding away because of their bad reputation.

If one is so concerned about shaving weight the A/C compressor would be gone, the A/C pulley it's self does not weigh much it is the cluch that has all the weight. Even if there was a lightened AC pulley you would be adding the weight right back on by reinstalling the clutch so the AC will function properly, and has anyone else here changed a compressor clutch with out breakin open the system? it does not look fun on our car... A lightened AC pulley would be a useless mod, like color matched piston rods

the crank pully has been the most noticeable mod, in terms of power gained. so, yes, it does make quite a difference! :thumbup:

[eTiMaGo]

It's hard to quantify the power gained if any, but the engine did increase in responsiveness, it revs up and down noticeably faster, my whole shift timing was too slow after changing it.

[whooppee777]

i'd like to do this mod, but i'd like to know if there are any cons to this type of mod. does anything get worn out from changing pulleys? changing pulleys changes the cam timing right? how hard is the install? i know theres a diy guide for iton here somewhere i jus want a straight answer from someone who has done it.

[whooppee777]

so i read every lil facet about pulleys on nst's website and these lite pulleys are the same diameter as the oem pulleys so they dont change timing in any way, right? its because they dont weigh as much as the oem pulley that makes better use of the engines output. am i right?

size size just lighter, so less rotational mass = better MPG and more HP transfered to the ground because less is being waisted trying to sping the hevier pulley

[NonStopTuning]

Crank Pulleys and accessory pulleys have nothing to do with cam timing, whether they be underdrive, overdrive, or simply light weight variants. The concept is in regards to the rotating assembly and the transfer of horsepower between the crank shaft and the accessories which translate this horsepower into the services they provide. ie the alternator, a/c, etc.

http://www.nonstoptuning.com/images/NST04pulleyPICS/AE86KITS/NST04015K86.JPG


Adjustable Cam Gears, also called cam pulleys by some, are directly attached to the camshafts and allow the individual tuner to change the timing of the camshafts, thereby changing the powerband of the engine. Adjustable cam gears are usually used in conjunction with aggressive aftermarket camshafts and wouldn't do much for mildly modified engines.

my problem is i have a dumb ass friend who works on cars, who has an accord with a turbo h22 engine, that thinks he knows everything about cars. and my dumb ass listens to what he says sometime and he told me it will change the timing. this coming from some one who works at a local monroe shop, and works on peoples cars while stoned.

[Dezod]

NST rocks!

We are a proud NST distributor and have MORE stock coming in!

[cali yaris]

I got my pulley on today, and there is a nice bump in low-to-midrange. Can't feel much when winding it up, but that's fine.

My only tiny gripe about this pulley is the timing notch is too small, barely there really. Won't matter much until smog time, though, since the car tunes itself. Overall, VERY nice product.

[cali yaris]

are the other two pulleys available yet?

[ChinoCharles]

They are being researched as we speak. Look for the GB coming soon!

That's what I want to see 1st. The Lotus graph looks terrible, what happened at 6k? As for handling my Yaris, I'm sure it's worth a little hp, but I wanna see the curve. I'm also sure that Toyota wouldn't leave more than a couple hp on the table in a market that is so closely matched.

[NonStopTuning]

Gains and dyno results can vary on different cars based on several factors. Supporting mods, weather, humidity, sea level, etc. But most sport compacts that have been tested show gains of about 6-10hp and torque increases with an NST pulley kit. Based on those experiences we can probably expect gains of about 5 HP and TQ on the 1NZ.

NST Pulley Kits provide very good throttle response, and they provide good power gains accross the entire RPM band. Usually an intake, exhaust, or header will only provide gains in one area, maybe the lower, or the higher power band, or maybe just at peak power points. Pulleys shift the entire power curve UP. Meaning the gains are always there. This is in part due to the great weight reduction in the rotating assembly.

Please take a look at the following... These are the results we've seen in some of our testing. ALL cars were 100% bone stock. Before and after runs were done on the same day, same dyno, within a few hours of one another. Some of these cars were even Auto Transmission cars. As you can see, the NST curves are higher than the OEM curves at every single point on the power band...

We have absolutely nothing to hide, nor are we in the business of producing and shoving junk down anyone's throat! I have been working with pulleys in one way or another for the past 10 years and pulleys are what I do 24/7. I take A LOT of pride in what I do, and would not take pride in building junk!

We do not post garbage information, nor do we try to make claims of 11hp and 18tq like some of our competition :barf:
We give you real world estimates seen from real world testing that we have done on real world cars. R&D, test, R&D, test some more, enjoy.


Thanks to all of you who have supported NST thus far. I certainly do appreciate it very much. Good luck and have fun with all your projects!

[NonStopTuning]

That's what I want to see 1st. The Lotus graph looks terrible, what happened at 6k?

Why do the Lotus graphs look terrible? The Lotus Elise and Exige are basically track ready cars out of the box. The Elise has some of the lightest and most efficient OEM pulleys I have ever worked with, and NST pulleys still provided positive gains.

What happens around 6,000 RPM is the Toyota Variable Valve Timing (VVTi / VVTLi) that kicks in. The engine makes a lot more power from 6,000 to redline, as evident in the graphs there.

The same thing can be seen in the dyno chart above posted about the Civic Si and the Acura TSX. Vtec kicks in around 6,000 RPM and power increases significantly.

As you can see, NST pulleys continue to free up power even beyond this point.

[Black Yaris]

well I jumped on the bandwagon and installed my crank pulley.... besides having the little bit of bling under the hood, there is a noticably better throttle responce, those extra 5HP to the wheels you can feel too, and for those of you that have tweeked on the exaust like I have it smooths out that rough idle a lot.... and this pulley combinded with the NST Short Shifter, it makes this car so much more fun to drive! never thought a pulley could do so much, but now that I have the crank pulley I can not wait for the final installment of pulleys

If you do not already own one of these you are missing out

[Dezod]

Mike & NST are a proven gain unit. Their units are reliable, excellent in construction and I personally use their products for my cars! They are an excellent company and we only deal companies that we know stand behind their products as much as we do.

On that note, we have crank pulleys in stock! Come and get em!

[TheCutsman]

One of my buddies said a harmonic balancer is needed to put this on. Is this true?? I saw a few posts about engine vibration and was wondering if maybe not using the balancer had anything to do with that.

[Motorhead6T5]

One of my buddies said a harmonic balancer is needed to put this on. Is this true?? I saw a few posts about engine vibration and was wondering if maybe not using the balancer had anything to do with that.These pulleys do not have a dampening ring,which will lead to more engine vibration down low. Will it have an effect on engine bearing life? Only time will tell I guess.:iono:

Its my experience with toyota you can't kill these things if you wanted to,so I would not be surprized if the engine still went 200k miles + anyways.

I am not trying to dirt NST's product,as I have seen tons and tons of people very happy with their product and actualy not one complaint. I just think people should be informed on all aspects of the modifications they are doing to their cars.

[NonStopTuning]

This is actually the fourth time we are covering this subject of vibrations, balancing, and dampers again. But I don't mind, I understand that your cars are a very large investment for all of you and I prefer that you be intelligent and informed about all your modifications. So here we go again... Please take a few minutes to read everything I have posted here, as I worked hard on trying to give you a good explanation on the topic...

In the past many engines were externally balanced. There was an external balancer attached to the outside of the engine, on the crank snout, used to balance the engine externally. The crank pulley in such engines would then be attached to this balancer. Removal of this balancer is a bad idea. These balancers were most often used on large (6 to 8) V shaped engines of the domestic muscle car era.

Take a look at any modern (1980s and beyond) Honda, Toyota, Nissan, or other japanese inline 4 and you will find no such balancer. These engines are all internally balanced, and this process has improved even further since the late 1990s. So the topic of a BALANCER does not apply here.

What you will find on ALL engines is a harmonic damper. This is a small rubber band, litterally less than 2mm, less than 1/8th of an inch, thick that is built into the crank pulley. OEM crank pulleys are often called DAMPERS. Try placing an order for a crank pulley at your Toyota dealer and your invoice will read damper. This rubber is used to absorb something called NVH, noise/vibration/harshness. Suffice it to say, this rubber is actually not very good at performing its intended purpose after as little as a few thousand miles. What happens to rubber after a couple years of humidity, weather, snow, rain, etc? It often becomes brittle, hard, and crunchy. Can something with these properties actually absorb vibrations very well?

Many many NST customers, including people on your own forums, have reported smoother running engines with NST pulleys. Especially at idle. How is this possible if the rubber is such a vital and super important piece??? Perhaps the rubber is not as important as it is cracked up to be???


Furthermore....


On the topic of the rubber damper, engine vibrations, or possible threats resulting from elimination of this rubber piece...

On a relatively understressed near stock motor with bolt ons or low amounts of boost like what most of the people on this forum probably run, a solid pulley will not have any life threatening consiquences. The factory pulley with a 2mm (less than a 1/8th inch) damper is primarily there for wide band NVH (noise vibration harshness) supression from the engine and driveline. Removing the damper and replacing it with a solid pulley may lead to minor addtional NVH but will not harm the engine. In fact, most people claim their engines seem to run smoother with NST pulleys.

The engineering reasons are that most modern engines have a short, strong crank with, a relatively high natural frequency. The dangerous second harmonic that can cause damage occurs at an rpm that this sort of engine will never see, in the area above 10,000 rpm. Even the stock damper is not tuned for attinuation at this sort of rpm so the argument is somewhat of a moot point.

Now small engines that are pushing the limit with lots of revs, wimpy cranks, super long strokes, lots of boost and dwelling in the upper rpm ranges for long periods of time can benefit from a damper designed to deal with this sort of operation but our engine is not like this, and probably very few people with this motor on this forum push the envelope that hard. How many 1.5Liter, 400HP, 11,000RPM Yaris motors do we have on these forums?

As far as I can tell, our engine has a strong and stiff bottom end that is well built for our intended use. It has an internaly balanced crankshaft which is less like to break due to torsional vibration.

There are a lot of Nissan guys who use underdrive crank pulleys in road racing series like NASA or SCCA. Road racing is much more punishing on an engine than other motorsports. The engine is subjected to run times lasting 23 to 45 minutes with the engine always in the upper ranges of its rpm limit. One race weekend is the equivlent of hundreds of 1/4 mile passes.

NST sponsors the first ever wheel to wheel Scion tC NASA Road Race car. This car has been using underdrive pulleys from NST with great results since day one.

NST also sponsors two drift cars participating in the professional US drift series, Fromula Drift. Both of these cars have been using NST pulleys with no issues of any kind for the past few seasons.

We could go on and on...

Is a solid crank pulley harmless to all engines? No it is not. Small, super high reving engines, when modified way past the simple bolt on stages may have problems. These engines reach critcal harmonics, past the 10,000 rpm range, an rpm often reached by certain race engines.

A mildly modded inline six will most likely be fine but one subjected to high rpm for long periods of time (90% of its life) with lots of boost will probably suffer. In this case , the stock balancer/damper is probably not adequate either.

Some of the older american V8 engines are externaly balanced and it is critical not to use a solid hub pulley not designed for these applications, or damage to the engine could result.

Our engines and most around here do not fall into the above catagories. Rest assured that your engines will not blow up and die or have a reduced life in street and even racing use with these parts.

I would bet that every "expert" that tells you otherwise has little personal, practical, real world experience with the subject.

Again, I understand that your cars are a very large investment and that you depend on them as your daily means of transportation, so I do not take your questions personally. However, this is the fourth time I have addresed this on YarisWorld. If I have to post this info once a month in this same thread, I will continue to do so. I do not take pride in building junk. No NST product is junk. No NST product is designed to cause you any harm or grief. I am not in business to sell junk. PERIOD.

Well you got a good sales pitch and all,but unless you have measured bearing clearances on the crank on high mileage 1nz-fe's and then compared it to normal wear on a engine with the same amount of miles with the pulley,its all speculation and crossing fingers. Road race cars are not expected to live long lives and typicaly don't if they are taken far from stock. So saying the thing lives though road racing is not the type of thing I'm talking about. I'm Talking about spinning a bearing at 120k and being out a motor,loss of oil pressure etc. I'm not claiming to be an "expert",I do however work on engines and know their function.:wink:

Do we have any new NST users with new reviews? Updates from current users? Any other questions/comments?

[eTiMaGo]

small update, something people might find useful, my beslt used to squeak a lot after installing the pulley. But that was because I turned on the air conditioning soon after turning on the engine, and the extra drag would cause the belt to slip and squeak.

So the solution, wait till you're moving to turn on the air conditioner, it's probably better for the engine in the long run anyway :wink:

You could also probably resolve this through tightening the belt by rotating the alternator slightly upward, but I have not been able to loosen the damn bolts :laugh:

Apart from that, I am more than happy with my crank pulley, and can't wait to be able to get the rest of the family :wink:

I cant answer number one, But would definitly like to know the answer.

Two however, if your engine breaks down, I can guarantee if you have the pulleys on, and the dealership sees that, they will void your warranty and blame the pulleys.

Good questions.

1. We use a grade of aluminum which is what the aircraft industry and NASA (cold space adventures) use in building certain components. We then HARD anodize our pulleys for extra strength. No, the main purpose of anodizing is not to make your pulley look pretty. Companies that tell you bare aluminum pulleys are just as strong as anodized ones should not be dealt with.

2. There is a US act called the Moss Act. Basically it states that ANY aftermarket component can be used, and can not void warranty, unless said component can be proven beyond doubt to have caused specific failure related to that area of the car.

2b. I have found through personal experience that dealer service managers will take very good care of their customers when the customers are professional and mature with their attitudes and behavior. Individuals who go to dealerships and act like the dealer owes them the world will be refused for the smallest of issues, others will not.

[NonStopTuning]

I live in the desert and my a/c is ALWAYS on. I think if this piece were to be built, it'd motivate me to do the entire pulley set. :)

Such a pulley would cost more than three times that of the crank pulley. The OEM a/c pulley has a clutch mechanism built into the pulley and unfortunately this design is very costly.

1. I would not feel comfortable asking you to fork over $350 for one single pulley which will not improve your performance.

2. I would not feel comfortable building 100 pieces when 97 of them would sit on the shelves for the next 3 years :eek:

I suggest spending your $350 on the pulleys we currently offer, and saving the other $350 for other goodies which will make your car much more enjoyable. Better yet, save it in your "what will NST build next" savings account. :wink:

[Motorhead6T5]

As far as the warranty is concerned,they will typicaly restrict your warranty if they see parts. The whole warranty won't be voided but the pwertrain might be. And like NST said there is the act that puts the burden of proof on the dealer. Yet your warranty will be restricted before you ever get any of it sorted out. Then I assume you would have to go to court and get a court order making them reverse the restriction. Which is more than a pain for most people with daily lifes with jobs. The car companys have great lawyers too. So their are law on the books to defend us,its no cake walk though. If you modify your car,its better off to assume that your warrany will be voided. Chances are,I don't think they would notice the pulley,if you are concerned get the grey one,so it won't stand out like a a sore thumb.

Edit: If for instense you had an engine problem,I would put the stock pulley back on then they wouldn't ever know. Thats what the mustang crowd does,they get new motors and transmissions all the time by putting their car back to stock before taking it in. Even if you have to pay to have it put back to stock by a shop, its worth it to not eat the cost of a motor or trans.

Unfortunately we have not been able to test the CR-Lite with the 1300cc Yaris, as we do not have any here in the USA. We have however, sold several of these pulleys to 1300 owners internationally and these customers have never reported any problems. My understanding is that the 1500 and 1300 both share the same crank pulley. You should have no problems.
