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!

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!

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

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.

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.

[auxmike]

Just wondering; If these parts provide so many benefits, why does'nt Toyota install them in the factory from the get go??

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.

25+ pages of positive results here on your forums alone, hundreds more pages, with thousands more positive reviews on other forums.

Good luck and have fun with all your projects

Glad you got one. And MicroImage is an excellent place to order any NST products.

I look forward to reading your review after your install

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/sho...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~
