NST (NonStopTuning) Pulleys. Info, Specs, User Data...

[chesspirate]

I purchased my underdrive crank pulley a couple of months ago, and have driven approx 10,000 miles since so this review is not "I just got it and it revs better".

I've thought about what to say, how to describe it, what the benefits are and all the blah blah blah. But if someone wants to know if they should purchase the product or not they need something a little more like...

There is no reason not to buy this product.

:thumbup:Hoping to have mine installed CR-Lite Pulley Set on Monday!

2008 Yaris LB 5-speed

I am running the NST 10% Underdrive CR-lite pulley. My only other HP-related mods are a Thunder axle-back and a TRD CAI w/WeaponR Secret Weapon dry filter. I just made 107 WHP and 106 TQ on a Mustang Dyno this saturday, in mid-70's (degrees F) weather.

I also am very pleased with the SSK.

hi. i'm about to install an underdrive pulley tomorrow morning and was reading over the diy from the other site. there mentions a tic tac sized dowel that makes me slightly nervous. was wondering if i could get one ahead of time just in case i lose this from napa or the dealer and what it might be called there. thanks in advance!

[ozmdd]

It's not hard to keep track of, but you REALLY don't want to lose it.

It's very easy to keep track of and is called the KEY :smile:

[redglare45]

I just got the CR-Lite Pulley Set installed. Great product. Butt dyno says there's some gains in HP. Also, seems to me that it revs quicker. Oh btw, they were the BLUE pulley's I bought from a board member.

Wow! Blue ones were made for a very short time, they're pretty rare.
Thanks again for the review and the kind words, good luck with all your projects!

Hi guys, i just installed the underdrive pully on my auto yaris!

On first test drive right after installing, i felt the engine idling is smoother. As i slowly accelerate to move off, i can feel the engine is having less "load" than before!:wub:

Now when i tried to apply more harder throttle, immediately the engine downshift and rev to the near the redline easily and happily!!!!!:burnrubber: :wub:

All in all, the underdrive pully is giving me better low-mid range power!:headbang:

P.S. I will like to take this chance to special thanks to Garm for his fast response on email, lighting fast shipping & nicely bubble wrap the pulley to ensure pulley is all round protected from any mis-handling by postman. Kudos to you, Garm!!:thanks:

[jonismyname]

time to say my part. installed my 10% UD pulley in about 15-20 minutes in a garage with air tools. if you're a little person you'll prob have troubles getting the alternator loose... and i found removing just the two upper screws on the plastic fender thing was enough to get to the pulley...

immediate boost in throttle response, and acceleration. car feels lighter and more lively. i've done a number of mod's on the cheap to my car, including modified intake and axle back, and nothing has done more for my performance than my pulley i installed last night, regardless of cost. very happy with product and will recommend at every opportunity.

Thank you.

[*MAD DOG*]

Just had the NST CR Lite Crank pulley installed at a mechanic. They quoted me $90 labour an hour. They did the job in just under 30 minutes and charged me $45 woot. :thumbsup:

First thing I noticed was when I put my foot on the gas pedal the car responded quicker and appeared to take off from a stop start faster and easier.

Then I drove around for a while with a big grin on my face and was very happy when a set of lights turned red (another chance for a take off test). I'm very happy with the NST product and would recommend it to anyone and everyone with a Yaris.

My wife has a 1.3 litre Yaris, I think the biggest gain would be on her engine. Maybe I’ll talk her into one of these and then get the 10% underdrive for myself. :biggrin:

NST FTW!

[Astroman]

The bodyshop at the dealership noticed my NST pulleys and asked me all sorts of questions about them and were quite impressed. I think my Yaris is the only one they've seen that has just more than aftermarket wheels on it. Over 50k miles so far on my pulleys and I couldn't be happier. :biggrin:

[ozmdd]

11K miles on my NST Underdrive pulley. 15 autocross events, 3 time trials. Zero problems, dyno-proven HP gains (see dyno thread), completely satisfied with the quality, aesthetics and performance of the product.

[Aothachos]

I'm not sure if this is normal, but I was checking the pulleys I installed, well the waterpump nst pulley is starting to get engraved into. Meaning the belt is digging into the pulley so that theres an engravment from the belt in it is this normal if anyone knows what i am talking about?

Yes, that is normal, everything will wear off eventually, even the strongest materials, just give it enough time and friction. The OEM water pulley is painted black, but when I took mine off it had a shiny strip where the belt makes contact.

Think of it almost as an infinite polishing machine :wink:

so eventually overtime I will have to replace the pulley? Is there a set certain amount of miles that NST recommends to replace it if so? It has been about 25-30 thousand miles since I installed these. I think it is also why my belt is squeaking everytime i start up because it is loose due to friction engraving its place in it lol

Hmm, honestly, I don't know, but then aluminum is lighter and softer than steel, so I wouldn't be surprised at all if it wears off much quicker. Can you really see/feel a groove where the belt sits? If it's just polished shiny I wouldn't worry too much. It would be interested to compare with an older OEM water pulley, see if you get the same wear after a while.

My belt is squeaking too, 1 in 10 starts I'd say, because I couldn't get it as tight as it should be. But I'm working on adapting the Scion xD belt tensioner to the Yaris and if I can make it work, I'll post the DIY :smile:

no the groove is pretty deep i say about 1-2mm, u can feel the edges perfectly where the belt sits on the pulley

[jouna]

is there a big difference installing the power pulley set versus the underdrive pulley alone? i mean is it worth it?

[NonStopTuning]

Yes, there is a difference and it is worth it.

Hi NST,
i just want to enquire something. ur parts here in this side of the world isn't so common(Indonesia) i needed more information, if i have the Thai's built yaris, would i need a different set that is intended for the asian built ones? i know that waterpump doesn't fit right away but requires some sort of spacer if im not wrong, correct? can you please elaborate and maybe provide more information on the other crank underdrive as well as the alternator. thanks.

[Yariz]

can someone point me to the new DIY for this, I keep getting the one that has moved.

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

I have posted this info several times in this thread, but will post for you again...


IFFF your 1.3 or 1.5 Yaris has a single-row (one belt) crank pulley, then you can order pulleys from our Yaris page on our website.

IFFF your Yaris has a two-row (two belt) crank pulley, then you will need to order pulleys from our Scion xA/xB page on our website.

Yaris 1.8L pulleys are also listed on our website on the Yaris and Scion xD page.


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

:thumbsup::thumbsup:

[Yariz]

Thanks guys, I got it...

[NonStopTuning]

I have a question, if the crank pulley has the same diameter as the one that comes origin OEM, whats the thing about changing the belt in the case of the ones that do not have AC? it does not make any sense

[Astroman]

I agree. If the belt is still in good condition you can keep using the same belt. I have AC and used my belt for another 60+ thousand miles after my crank pulley install. I just replaced it last week because it was finally starting to crack and wear after 80k miles. It was the original belt that came on the car.

[WeeYari]

I have a question, if the crank pulley has the same diameter as the one that comes origin OEM, whats the thing about changing the belt in the case of the ones that do not have AC? it does not make any sense

Comments about changing the belt are specific to the installation of the 10% UD pulley, not the CR Lite. In cars without A/C there is not enough swing on the alt bracket to achieve proper belt tension with the 10% UDP installed. Therefor a smaller belt is required.

[Nets]

but my car has te same crank pulley as scion xA xB and it does not have AC so the diameter being the same it does not make any sence to change the belt

WP and ALT pulleys are much smaller and sturdier. I'd be willing to bet they're impossible to break.

[*MAD DOG*]

It's strange there has been no reply from Mike from NST. I've sent him a pm and a pm on facebook. Has anyone else tried to contact him about this?

[Vioz]

Damn that is crazy now I'm worried about my WP pulley because the belt is making a grove into it and I'm afraid its going to give in any day now, but my friend is a mechanic he said it's fine.

This is something I can't stand. You would at least think he would reply in some way, even if it's a simple "We're looking into the problem.".

[tk-421]

If you take the time to review this very thread, you can see how Mike always answers all posts. Just give it some time.

[*MAD DOG*]

If you take the time to review this very thread, you can see how Mike always answers all posts. Just give it some time.

I'm not slamming Mike. I know he answers questions about his products. Normally this is done promptly and within a day. This time no response as yet. Maybe he's on holiday or something. I'd just like too see what he says about this issue.

From what I've been told we don't need a dampener on these pullys. But that pulley that's come apart looks like metal fatigue, maybe caused by no dampener.

A lot of us have this product or similar, so we all have a vested interest in Mike's response. I need my car to get to work, I know how much better it performs with the CR Lite Crank Pulley, but if it's going to shatter and smash into pieces in my engine bay doing damage, maybe I should go back to stock pulley.

I am aware that the failed pulley shown is the water pump pulley. I have not heard of a failed NST crank pulley.

[tk-421]

From what I've been told we don't need a dampener on these pullys. But that pulley that's come apart looks like metal fatigue, maybe caused by no dampener.

The dampener/no dampener subject has been discussed and rediscussed ad-nauseaum on this very thread.

Additionally, the dampener/no dampener subject only applies to crank pulleys. The broken pulley in question is not a crank pulley, hence there's no point in bringing it up. The stock WP pulley does not have a dampener.

I am aware that the failed pulley shown is the water pump pulley. I have not heard of a failed NST crank pulley.

Exactly. No need to worry over nothing. Every product out there is prone to damage due to various factors -- some could be attributed to the manufacturer, others to the consumers and the way they (mis)use them.

[*MAD DOG*]

....The broken pulley in question is not a crank pulley, hence there's no point in bringing it up. The stock WP pulley does not have a dampener.

Ummm i've already stated it's the water pump pulley Bernie.

Bernie,

I'll choose what, when, why and how I worry over things, I always have and will. Why are you making a mountain out of a mole hill? This is for Mike to answer, isn't it?

[tk-421]

Ummm i've already stated it's the water pump pulley Bernie.

I know that, buddy. Which is why there's no need to bring up the dampener subject, is there?

I'll choose what, when, why and how I worry over things, I always have and will.

That's fine and dandy. I'm just trying to avoid you a headache over imaginary problems. Worry away if you must. :smile:

Why are you making a mountain out of a mole hill?

As you can see, it is not me who is making said mountain (or interested in doing so). I am, however, trying to help protect a brand that I happen to be a supporter of.

Having one (allegedly) faulty pulley (out of hundreds if not thousands of pulleys made by NST) potentially damage the reputation of a company that is backed by the tuning/performance scene in general but also these forums in particular doesn't seem like fair treatment to me, especially since we don't have enough facts about this particular case to reach any kind of conclusion either way.

Also, having someone post a potentially damaging post without consulting with the fabricator first doesn't seem fair to me either. But I guess that's just me.

[*MAD DOG*]

This is for Mike to answer, isn't it?

Yes, yes it is.

[goliath1812]

Also, having someone post a potentially damaging post without consulting with the fabricator first doesn't seem fair to me either. But I guess that's just me.

Seems perfectly fair to me. He's just trying to show everyone what happened in his case. Is it only fair for people to rant and rave about products, but when one fails, you're not allowed to tell anyone about it?? This is a simple "be aware of" thread, and sure, it would be nice to have contacted Mike first and he would be getting a replacement right now, but it still deserves to be info that is available for everyone to see what happened in this case.
It doesn't seem to be ruining Mike's reputation, we have pages and pages of nothing but praise for his pulleys, this it just another view on the subject of what can possibly go wrong.

[d1nzfe]

If u can still see my past posts, i did post on this thread before asking about this pulley. I have post some doubts on the wear and even post a pic on it long ago.I have great confidence in the product. But it fail me after 50000km++ so its the end of NST road for me. This is a fact.

[shinlee]

I think he's being perfectly fair about his statements over the pulley breaking on him. If I bought something somewhere, and it broke on me, I'd be damned sure to tell EVERYONE that I knew who might buy something there as well. That being said, I still fully endorse NST pulleys, as I've had mine for almost 2 years now, and I still love them. Just nobody can make something 100% perfect, there will be some problems somewhere, sometime.

[Astroman]

60+ thousand miles on my full set and no problems. Perhaps the bolts were improperly torqued? Not bad seeing 1 problem out of thousands of users.

[suiller]

and for my "poor" 1NR-FE also known as 1.33 (101hp)... which pulley should I look for ??

[evo165]

Hi to all, can anyone Thai made Yaris mount on the water pump & alternator pulley without any problem. All Thai Yaris with this mod, PLEASE advise & confirm... :redface:

About NST (NonStopTuning) Pulleys, does anybody know if they work in a yaris sedan 1.5 a/t? I also ordered but not intalled OBX headers, K&N Typhon intake, Magnaflow muffler and the sprintbooster (electronic throtle accelerator).

I'll apreciate all your comments.

Thanks

[modelista]

For those who have the full lite pulley set, would anyone care to give their impressions? I'm interested in these.

[yaris2010RS]

^ hey aurora, i have a cottage there (ninth line area)

as for the pulley set its really amazing. there is such a huge difference with them on. only issue is getting them on :p crank pully wasnt too bad to put on but holding it while tightning the blot was a challange. i also have lite water pump pully which took some time too get on but was very happy with the results none the less.

[WeeYari]

For those who have the full lite pulley set, would anyone care to give their impressions? I'm interested in these.

The biggest bang comes from the crank pulley. The others in the set are mostly cosmetic.

[modelista]

^ why are the others in the set cosmetic? Is there anyone that started with just a crank pulley and added the other two pulleys later? I'm definitely going to get at least the crank pulley, but I'm on the fence on the other two.

[yaris2010RS]

i put just my crank on first and tested it out and i noticed a massive difference. put the water pump pully on and noticed nothing. the water pump pully i got was also grey so its not cosmetic at all..... i recommend only getting the crank and if i could do it all over again thats all i would get. the stock water pump pully is maybe only 1lbs difference then the lite one but the crank is almost a 20 lbs difference

[Klink10]

^ why are the others in the set cosmetic? Is there anyone that started with just a crank pulley and added the other two pulleys later? I'm definitely going to get at least the crank pulley, but I'm on the fence on the other two.

Yes....however it was when they introduced the crank first. Then the others came out. I believe cheaper prices were in back then also.

[why?]

hey, when you are talking about things that rotate every ounce counts. It might not be a ton, but the lighter those pulleys are, the less effort it takes to spin them, meaning more power for what really counts.

[sito]

MR/MRS NST,

Please reply to me back in email if you see this.

I sent dozens of emails to you, asking when will i get back my replaced water pump pulley. It's been 3 months and i'm still waiting for my PULLEY.

THANKS!

[ilikerice]

even though its not really a huge wieght difference.. i compare it to running wide open with the A/C turned on and then doing it again with it turned off.. i got all 3 and i like it alot.. i really wanna do the lightwight flywheel and clutch set when i do the LSD also.. i hear that is a HUGE difference, 3x then the crank pulley

Anyone able to contact Mike from NST? I sent emails to NST and they didn't reply me anything till now. Can anyone help? Thanks.

Looking at the http://www.nonstoptuning.com/NSTPULLEYS/pKitToyYaris.html
website and i am not sure which to put into my 1.5L 3 hatchback Yaris.
I believe the 10% under drive pulley would make most sense but I'd like to hear someone's thought about this decision.
what is the WP-Lite & ALT-lite KIT for?

[car_buff]

Water pump and alternator. They are not underdrives, just awesome looking lighter version of own equip. Lighter means faster response from your engine.

[ilikerice]

water pump and alt pulleys are more cosmetic.. they are lighter, yes. but not enough to make a difference.. i got the 10% crank pulley and the waterpump/alt pulleys as well. i barely can tell the difference from the oem.. but they look cool!

I am a bit on a budget, would it be worth just getting the "NST 10% Underdrive Crank Pulley 1.5L" only?

[cali yaris]

^ Yes. if you're on a budget, get the crank pulley. There is no downside to the underdrive version (you'll even use your stock belt with it), unless you are (1) supercharging or (2) bumping a huge, demanding sound system.

If I remember correctly, NST is not an official vendor on YW anymore, so you'll have to try to go directly to their website and contact them through that...

Most people have had very positive experiences with NST, Mike has been very patient explaining things, emailing additional instructions, etc...

Hi fmicle,

The last email i received was 5 months ago. NST told me that my pulley was replaced and will deliver it back to me soon.

And during these 5 months, i keep on waiting. Nothing was delivered and I sent tons of emails to their official website asking them where is it and there's no reply from them... :mad:

[skootdog]

Does it affect the timing of the engine?

no, its on the accessory belt not timing chain

I thought since they are the official wholesaler, nothing will go wrong. But i was wrong. If this is their way of doing business, ignoring internet users like us, i guess there is nothing we can do. Perhaps i can lodge a complaint against them using legal means, since i got the full emails of our conversation and receipts of my local courier.

nstonaim is his AIM username. I haven't been on in quite a while, so I don't know if he's ever there anymore or not. You can give it a try though.

Long time no see YW!

As many of you know, and have on your cars, we set up design and development on Yaris pulleys back in 2007 and ran the original GB here:

http://www.yarisworld.com/forums/showthread.php?t=3239

Unfortunately, due to lack of demand and slow market conditions, we had to stop mass production on our Yaris pulleys and make them available only as special order items, a couple years ago.

We are considering a Dec/Jan group buy on a run of crank pulleys, at a discounted group buy price, if the community is interested.

All pulleys would be the same lightweight aluminum we've always used and a special run of colors would be made available: red, blue, black, gold, purple.

Would you guys and girls be interested in such an offer?

[47_MasoN_47]

You just missed me, I just bought a complete set a couple days ago from CTScott.

[Jerkratt]

Mike I've been trying to get in touch with NST. I'll message you

[cali yaris]

Mike, have you made any substantial changes to your designs? There are quite a few broken NST pulleys (crank and water pump) out there now with the old design.

Maybe start here: http://www.yarisworld.com/forums/showthread.php?t=46987&highlight=broken+nst+pulley

with some customer service. :rolleyes:

[Lars]

Would you guys and girls be interested in such an offer?
Any chance I can get'em in Germany without crazy shipping prices? :tongue:

[ilikerice]

my water pump pully has a really DEEP groove worn into the pulley from the belt. Is there maybe a exchange that could be done with broken or worn pulleys?

[NonStopTuning]

Every NST pulley has always come with a one year warranty. Out of thousands of pulleys we've sold, a few have had issues and those few have been replaced. We have tried to work with those outside the warranty periods as well. No one has ever been told, "sorry, you're out of luck" when the proper steps have been taken. Warranty claims and questions are best handled, and a mutual solution for both parties is always best reached, via one-on-one communication through email, not through internet forum posts.

I encourage customers with issues to please email us. Trying to hurt our reputation/sales on the forums only makes matters worse and makes it more difficult for us to try to assist you.

Our design on our crank pulleys and water pump pulleys has changed slightly. Our new pulleys have holes in them, rather than slots. Holes seem to hold up slightly better in the long run, though there is not a huge amount of difference. There are thousands of NST customers running pulleys with slots in them since 2005. Are there a few cases where pulleys have cracked? Yes. Are there thousands of other very happy customers? Absolutely.

If we move forward and the community wants to support our products, we would be happy to offer a group buy discount and move forward with this idea. If not, we will continue to offer pulleys on a special order basis, as we have over the past few years.

Many thanks, best of luck with all your projects everyone!

My 10% underdrive crank pulley came to me in 2008 and has been great for me however the one question I do have is whether or not you have a pulley that can handle 7-8k rpm operation without coming apart? Right now my research and past experience by another member is that once you really get into the more extreme rpm range you are pretty much going to have to use a stock pulley because these "upgraded" pulleys cannot handle the stresses at that level. Thoughts?

Just received my CR Lite Crank Pulley on special order. Took awhile but really hoping it was worth the wait. Thank you NST...

Thanks bud, I appreciate the kind words.

Your NST crank pulley should be able to withstand RPMs higher than the OEM range. I realize there was a case where one of these pulleys cracked on a higher RPM engine, but I also know based on my personal experiences with our pulleys on several high revving race engines of our own, our pulleys have stood the test of time on several race engines constantly banging limiter, at 8,000 rpm and above.

The NST AE86 ran a Toyota 4AG turbo setup (OEM 4AG 100hp 7500rpm) making over 350hp and going past 8,000rpm from 2007-2012. Same setup, same NST crank pulley, no pulley failure. Our current Formula Drift AE86 runs a Honda F20 turbo setup (OEM F20 200hp 8500rpm) and makes over 500hp going past 9,000rpm.

This has also been the case with other NST race cars, 4cyl, V8, n/a, turbo, supercharged, Toyota, Honda, Nissan, etc.

Side Note: IF in theory, the NST crank pulley is not able to withstand higher than OEM RPMs, then neither should the OEM pulley be able to withstand such RPMs, being that the prevailing thought pattern has always gone down the road that, "the Toyota pulley is designed for this engine, the displacement, and the RPM range." Real world data and theoretical discussions are not always the same.

Best of luck with all your projects!

There is something odd going on with the 1NZFE at high RPM that causes it to reject aftermarket crank pulleys. Lost one of yours at 7300rpm on one motor, had an issue with a Beatrush pulley on another.

The OE pulley has been running solid at 7500rpm.

Perhaps a solid (no holes, no slots) lightweight crank pulley is worth a try, something that we have the ability to produce for race use - going past 7500rpm.

For street cars, our regular Underdrive Crank Pulley and NST CR-Lite Crank Pulley should be, and have proven over the years to be, sufficient.

The slots/holes were not the point of failure for us, it was the mounting point. There is very little cross section around the mounting hole, once the unit failed we could see that. The front and back cuts in that area left very little material in the corner, it was not as thick as the face of the pulley, and this is where it cracked.

After the NST failure I went back to the OE piece. Some time later we found the Beatrush unit, tried it on another motor and the Micro Image piece on our 2012. The Beatrush unit was much beefier, but ultimately still had an issue - I was very disappointed when we got it because we were given the impression it had an elastomer damper, but it did not, and it was nearly as heavy as the OE piece. Once we noticed a problem with the Beatrush (took almost a year) we went back to stock on both cars. It just wasn't worth the risk for us.

I believe the issue may be accessory related. Not having a self tension belt system on the 1NZFE means there is nothing to help absorb the vibration once you eliminate the dampened crank pulley.

I sure would like to see ATI or Fluidampr build one.

Our NST (the exterior damage is road rash from when it popped off and passed me on the track):

Beatrush, has a more material around the bolt area, but still has issues beyond 7300rpm:

When Micro Image designed its pulley they addressed the cross section/mounting point concern, and still managed to build a very light pulley, but we never ran one long enough to see if it would let us down:

This is probably a dumb question but would like to ask anyway: What happens when a crank pulley, wp or alternator pulley fails on the road at speed..?

When the crank pulley goes your engine will overheat, necessitating a head gasket replacement - really if any of them goes you are screwed because the belt is no longer spinning the others.

[Astroman]

My NST lite crank pulley has been working great for years however I'm not racing and have the stock rev limiter. My NST waterpump pulley though had a crack and a very very deep grove wore in from the belt and I replaced it with another NST pulley that was used.

[cali yaris]

What happens when a crank pulley, wp or alternator pulley fails on the road at speed..?

What Jason said, plus the fact that pieces of metal could be flying around either in your engine bay, under your car, or on the road. In Jason's case, they were also winning.

hahahaha ^^ he got beat by his own pulley lol
