Personally I wouldnt touch the BBK or ASP. BBK and summit are the same brand and both have a habbit of deteriorating on cars after a short time. And asp may be ok now but a couple years back hey had some quality control issues and the inner rubber hub would separate from the pulley causing some pretty bad damage. The powerbond and the slp are actually the same pulley in a different box an would get my vote if i was going with a lower end under drive pulley.

I personally have an ATI which is regarded as the best ( i only bought it because i got a good deal) it what gm high performance uses on their builds as well as the Katech team. The reason being is that ati is the only "true" damper out there the others like powerbond bbk etc just have a rubber hub in them to help reduce crank vibration. ATI is the only one with a special damper formula to actually get rid of the vibrations of the crank. Now the ATI is only a 10% underdrive but often provides the same if not more hp than the other pullies because it not only underdrives the accessories but it correctly dampens the motor decreasing vibration and thus increasing hp. If you're dead set on a new one then go with the powerbond hands down, if you can ait a but then maybe hold out for a used ATI.
