Default Crank Pulley Options
Finishing up the 440 build for my T/A. I am looking into crank pulleys and I'd like it to be under drive pulley, but should I be looking into a damper? Balancer? or just a simple pulley. I am asking this because I know of ATIs products...

What would you chose or have gone with and why?

Personally would opt for the 10% to full size. What kind of power do you plan on making? RPM? Don't think of a dampner as a power piece as much as it should be considered an insurance piece. With this "insurance", you protect your investment at high rpm's....might pick up a few too - even at full size

Just read something about 10% vs 25%... 10% it is! Power? I'm not sure what it will make, but will be spun to 7500... I'll grab the 10% w/o A/C.

I've been running a Powerbond/SLP 25% underdrive for years without issue. Numerous builds and combos, all strokers and ZERO issues.
