KStang3.8 Posted March 2, 2010 Report Share Posted March 2, 2010 What is the difference between a 42% and 25% underdrive? are there any negative effects on my car with either one? Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted March 2, 2010 Report Share Posted March 2, 2010 42% is to much for the street...wont charge hardly. stay away from the race sets like that Quote Link to comment Share on other sites More sharing options...

CRed05 Posted March 2, 2010 Report Share Posted March 2, 2010 I'd say there's a 17% difference Quote Link to comment Share on other sites More sharing options...

AJ Posted March 3, 2010 Report Share Posted March 3, 2010 i have 25% on the vette and no problems. its made by powerbond. Quote Link to comment Share on other sites More sharing options...
Zipline Posted March 3, 2010 Report Share Posted March 3, 2010 Stay away from 42%. I've heard good things about the ASP pulleys. Never looked into the Steedas but you'll probably pay an extra 20 bucks just because it says Steeda somewhere on it. In the end, a pulley is pretty much a pulley. I'd get whichever one is cheaper.

Guest Removed Posted March 3, 2010 Report Share Posted March 3, 2010 the thing with the 3.8s tho is, its part of the balancer Quote Link to comment Share on other sites More sharing options...
Zipline Posted March 3, 2010 Report Share Posted March 3, 2010 Well shit. Do they sell a kit that contains all of the pulleys besides the crank pulley? That would probably be easier if it's part of the balancer. Quote Link to comment Share on other sites More sharing options...

That would probably be easier if it's part of the balancer. last one i did on a v-6 car was just a crank pulley assembly , but some places have there standard pic of pulley's , and that nots how it works on these Quote Link to comment Share on other sites More sharing options...
Zipline Posted March 3, 2010 Report Share Posted March 3, 2010 Yeah the 4.0 doesn't have this difficulty as far as I know. Just a few bolts and a torque wrench. 4.0 > 3.hate Quote Link to comment Share on other sites More sharing options...
