Default Underdrive pullies.
Which companies make them for the C5? Who sells them and what is a decent price?

Thanks for any and all responses,


S.

I bought one from MTI once. They sell the ASP which is a very good pulley (no knock sensor problems.) www.motorsporttech.com

They really aren't worth the hassle in my opinion. If you really must have one, MTI makes them and sells them for a few hundred bucks.

various vendors sell the ASP pulley...can add 8-10rwhp but best to add when upgrading cam so you can save on labor. Good thing about u/d pulley is they add power across full power band and not just peak.

We keep the ASP pulleys in stock. It is a good performance upgrade as previously stated but the labor for the install is usually high because the rack has to come out.

Thanks for the replies! I have the car in the shop now for routine maintenence things (40k mile check up) and one of the pullies makes a lot of noise when the motor is cold (squeaking). I figured that is this stuff has to be worked on anyway why not just throw on new pullies while we are at it.

Thanks again,

S.
