"The ASP is probably the lightest compared to others, but is not known for it dampening ability."

Is there a gain on A4? dyno proof? not I can feel the difference...
Then there's this OD pulley question, do you really need an OD pulley?
"prostock_bigblock" sais you do, but there's a lot of guys on here that running the u.p. without the o.d.

Personally I don't think the SLIGHT weight difference between the steel SLP/powerbond pulley and the lighter aluminum pulley's will make a hp difference. I think the size of the pulley is where 99.99999% of the gains come from. As far as spark knock, the steel powerbond pulley won't distort over time like some of the aluminum pulley's have and cause KR. The SLP site says that the powerbond pulley won't cause KR, and it doesn't. I have the SLP pulley and data logging show's that I definately don't have any KR issues.
