Anyone out there installed the ASP 25% UD pully? Mine has a serious vidration in drive at a stop. Just wondering ....since this is a TECH forum.

 

What year is your stang? Cus the 25%ers are for 98 and earlier. 42% is 99+.

 

Not according to ASP..the 25% is what they sell for an 04 3.8L...I do have the 42% pully from another vendor....you think changing them out will help?

 

WOA! I would change it out. As far as I know, the 25% pulleys are for the pre 98's cus they have a lower HP rating. When the 99+ splitports came out, they made the 42% cus the enging was more powerful. I'd change it out for damn sure.

Do you really think it makes a difference?

 

Ok, I believe you. But DAYUM? Seroiusly, why put a 25% on when they make a 42%? Also, it could be that you got a defective one. I've had absolutly no problems with my 42%. You may want to contact ASP and ask them for advice. That's what I would do. Maybe they will trade you up to the 42%.
But then again, I got the MotoBlue pulley.

 

Hey yellow where did you get your motoblue pulley from?

Yea, put the 42% in, but I've never had a problem, are you sure everything is tight?
