i bought the bbk u/d pulley. never dynod the car, but i did take it to the track b4 and after. i did see an .1 drop in et and gained 1 mph. i dont have any afermarket in my car, and my lights dim if im not on the throttle. it has shut down if i have the wheel turned all the way sometimes. part of that has to do with my alternator needing replaced. i have always had charging problems, and the pulley didnt help.for 60$ i think it is worth it. with the right tools it should only take 20 minutes! gl with ur choice

 

Hey electronblue. I have a under drive pully with a new belt. neither one have ever been on a car, you can have if you pay shipping. the only thing you would need is the longer studs to bolt it on. Lg motorsports will sell the bolts for $10.

Been there, done that, took it off and went back to stock. Not worth the electrical hassle.

 

I'll take it. Email sent.
