Interested in UDP. My older brother had a 2001 Max SE, when he put his UDP on, the belts would make noises, like it wasn't fully running tightly, He changed the belt twice to different sizes but couldnt get the squeaky noise to go away. Is this normal cuz I want to put it on my 2002 max se. Please advise. Thanks
What are the gains too?

 

No, maybe the belts were to tight? The pully does wine (very low) but the belts should not squeak.

Check the deflection.

I get good gains at low RPMs, a few HP.

 

The main thing about the pulley is you loose some unwanted pounds, thus freeing up more power!

 

did absolutly jack siht....its a mod to say that u have...i have an 01 but i didnt feel any diff or hear any noises....

 

loose some weight on your buttocks and you shall feel it

 

It does have provable gains via dyno, and it makes engine response faster as well...

 

I've had mine for 8 months, no sqeaking ever. Gains are there proven by my race (at the track) with a stock 2k2 SE auto. I pulled on him thru 1st gear (where gains from the UDP are most substantial)
