Installing my ASP " piggyback" pulley this weekend. My car is completely stock ( 22,000 miles ) and i was wondering if any of you guys have done this mod? Notice any gains?
Thanks

did mine a while ago, have had no problems with it charging in case you were curious.

as for an improvement...hard to tell, seemed to rev a bit faster, but for actuall improvement..it's mostly in your head, very hard to feel 5 or 6 hp.

 

ttt want to see some feedback

 

I have heard the gains are very minimal and have heard of people have charging issues.

Not an ASP, but a pulley is a pulley.

 

I had the march pulleys on my 97z, I didn't notive any gains except at nigth when all my lights where on and I'd come to a stop they would dim a little. Nothing serious I ran them for over a year and had no probs with the battery. As for the install, I just went to autozone and rented there puller. The balancer was quite hard to get off, I though I was doing something wrong it first. So don't let that stop you. Once you get it off the rest is simple.
