These are Goodyear numbers TSP has listed with the 25% UD Pulleys.

The SLP pulley is supposed to be the same as the Powerbond and you will have better luck finding PB cheaper.
Here is thread where Scoggin Dickey said they will create a package deal for $200 (includes powerbond pulley and belts).

I have been running a underdrive pully (SLP) for well over 150,000 miles ... yes I said 150,000 miles with the stock belt tentioner with no problems at all .... the belt tentioner has 197,000 miles on it and its still going strong...if this LS1 would ever wear out I'd build a bigger motor.

considering even the best underdrive only yields <10hp....and probably ~.1sec .....any of them that are the same % should be basically identical.
its not like the difference between shorties and LTs....

The gains should be identical, but it's the reliability(no belt throwing) that matters. I have heard alot of threads where the ASP pulley's have thrown belts. You don't hear that about the SLP/Powerbond pulley, because it has a higher retaining wall so belt throwing isn't a problem. I've had a powerbond on my car for 3-4 years and have never had a problem. I vote SLP/Powerbond.

I am sorry but I do not ever see any threads about ASP's throwing belts. All is EVER hear about is how the Powerbond/SLP has higher retaining walls so it doesn't throw belts. I have a ASP and have never lost a belt, granted I'm only spinning 6k but I doubt I'll have a problem when that is raised to 6700RPM. All with the stock tensioner.

thanks for inputs.
OK, at the track which pulley will lay best et and mph? the 25% UD ASP pulley or the 25% UD SLP pulley?
i'm saying that with correspondance to weight of each pulley since they say the whole SLP pulley are made of steel while i think if i'm not mistaking the ASP are made of aluminum and steel, what are your inputs on that?

ATI I believe is the hands down best UD pulley for LS motors. And they are priced respectively. Im running a Powerbond with no issues. Asp is lighter then SLP/Powerbond. Difference wont matter between the three at the track as far as weight goes.
