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...

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!
