crankshaft pullies

Are they worth a damn? What kind of gains do mildly modded cars usually see from them?

Are you talking about underdrive pulleys? If so I have heard both good and bad things about them. Some people claim a 4-5rwhp increase with this mod.

if you can find the used they are a good "every little bit helps" mod in my book.

not much of a hp gain, more of a torque gain.

i experienced no loss of charging either like some people.

oh and by the way...i have mine for sale...lol...PM me
