Me and my boy have used ASP Pulley from our first ls1 head,cam and nos builds with no issues EVER. I have used it on three motors and him two. I have it on my 545hp 402ci and a 200 shot,he has has it on a 383ci w/200 shot and no issues or a thrown belt. Still factory parts holding the belt on for him.

This is good from a performance standpoint, but bad from an engine protection standpoint. But, I am glad you are having a good experience so far.
This is the way I just went after doing the research.
Dont use any of those junkers.. They have been known to destroy timing chains and dont effectively manage harmful engine vibrations.
You need to realize its not just a "PULLEY" its a harmonic balancer / damper.
You need something like an ATI or BHJ or dont waste your money.

^^^ I have to completely agree, the 10% ATI "Harmonic Balancer" has been shown as effective in dyno results as the 25% "pulleys" offered from others just do to the fact that it is a properly balanced to reduce vibration which will also protect you from possible part failure in the future. It comes down to the typical "you get what you pay for"
