Underdrive Pulley Kit - Which One?
I've seen the ASP and the BBK brands. Is one better than the other?
The Pros of installing one are well advertised. Are there any cons to having one?
Are you guys seeing the claimed 10-13RWHP gains?

I just (tonight ) finished installing a POWERBOND under drive damper. I installed a pinning kit and used an ARP Bolt to install it. Its a QUALITY piece! Unless your going to spent=d the extra dollars for an ATI rattler or one of the other active dampers,,,,POWERBOND is an outstanding damper. Its already got a key way machined in the hub for a pin!
I heated the hub with a heat gun to 140-150 deg and used an install tool to press it on. Went right on!!
