which material? not really sure.

i should be getting my slp ud pulley soon ill weigh it if anyones interested...i went with slp because of the thicker walls...had a previous experiance with another brand on another car where the belt would jump off every couple hundred miles...

What does dampening do or mean in regards to the above post..
"The ASP is probably the lightest compared to others, but is not known for it dampening ability."
Thanks. Be kind to the stupid

You need to buy an OD pully too?

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.

gains r between 7-13RWHP .
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.
