sorry if my comments were negative or had a negative "jist" but i jus wanna know, maybe you can pm me the negative effects?

 

NO NO NO I'm sorry, I only meant to explain my concern on this, lol. Do not worry, I never sense anything negative about your post. I was just explaining myself....

 

ABout PMing you, of course as soon I have any negative effects I will post them.

 

Ok so I just orderd the pulley set (water pump, under drive, alt) I am wanting to know what is the horse power gain? Is this mod worth the money?

 

suppose to be 10whp, I don't have actual Dyno sheets, but those are the claims.

 

Excellent thread - since this is an easy mod with very good performance output, then we need to know if there are any problems....very happy to hear that they are running strong.....after my header/spipe....NST will be the final touch!
_NEEDS TO BE A STICKY_MODS

 

Just to keep it alive for now, any else have a personal opinion, it doesn't have to be over 50,000 or 60,000 miles, It can even be any one that has them. Just your opinion over the product and if you had any problems. If not then say what pulley you have and your results and opinions. Thanks.

No bashing please.

 

I have over 80K miles on my tC, I'm not aware of how many miles are on my 3pc. set from NST, but the set itself is nasty.. I love it. I have had no issues since my engine rebuild.

 

^^^ Well if i remember correctly you had engine failure at around 60,000 miles and you put your NST set on like right after that ? So im guessing 20,000 miles or so.

 

Could very well be Thanks, I really didn't feel like doing math

 

just got mine on yesterday, its the NST underdrive. it most def pulls harder in the mid to upper range. not much of a diffrence or power but enough to feel it. dont expect a night and day diffrence

 

But some people do feel a difference from night and day, makes me wonder. Do you have any other mods?

 

For who ever wanted a dyno:



It made 11.6whp and 18torque. Dynos were done within 15 minutes from each other, only difference was the crank pulley. (By the way, this isn't my car, just one I found on ZPI's forum)

 

^Thats yamaha16bw car. He had an S-pipe, mid pipe, and i think CAI, along with the ZPI pulley

 

All added at the same time of the dyno or before the pulley dyno..?

 

In ZPIs web, does it say from what car it is, and what mods does it have?

 

The beauty of the internet. People also say they feel a world of difference from a CAI in an xB. My car goes VROOM now instead of vroom so there's a difference :\

Take internet opinions just as that....opinions.

 

I have had the NST pulley on for about 5K miles. Car has 10K miles on it.

 

Accounted for the next update.

 

The first dyno is with all of the mods except the crank pulley.. The second dyno is with the crank pulley added.
