Man! These pulleys are DEFINITELY off the chain! I can feel the quicker throttle response throughout the WHOLE rpm range (mostly low end though). Even respondes quicker when on the highway in 5th gear and you press down the pedal.

Now if I can just get some poly mounts and get rid of the "oversteer" and "wheelhop" I should be good to go.

Thanks once again Pete!

If you're gonna go with Tranny mounts...PM Pole120 and get his mounts, definately the best way to go...

i read that the underdrive pulleys were bad for the motor since they dont have a damper for the crank. wich one did you use?

Thats's only if you use the crank pulley, and YES you are right, the crank pulley WILL do damage to the engine. However, after much discussion, it has been decided that underdriving the alt. and p/s pulleys will add the desired hp without doing any damage.

That is a GREAT question! I just so happen to be able to answer it once and for all, so that anybody that searches for this answer can find it right HERE:

#K060730

You see, there have been many belt sizes mentioned when this question has been posed, and I have read anywhere from a #K060725 to a #K060735. Apparently any of these three belts will work.

However, I originally bought the #K060725, and when my UDPs were being installed, the mechanic couldn't get the belt to fit. In a last ditch effort, we had to call in a #K060730, and this belt slipped RIGHT on.

#K060730, final answer.

I also REALLY needed the new belt. Got rid of the squeaky noise emitted when the engine was cold.

Oh yeah, for the record:

I have experienced absolutely NO engine vibration (NVH) at all whatsoever. I read about the NVH caused by UDPs in multiple threads, and it was something that made me consider NOT installing them.

However, my car runs smooth as a baby's bottom with a few more ponies to push.

Maybe they were talking about the crank pulley causing the vibrations (NVH) and not the alt. p/s pulleys.
