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?

 

C'mon you know better....lol. This subject has seemed to be beat to hell lately. Harmonics, harmonics, harmonics. ATI seems to be somewhere (always) on top.

 

Fineeeeeeee I'll use the search. lol.

 

Lol....didn't want to be that guy.

Here's some help buddy. Best one I've read in awhile.

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.

The ATI 917239

 

Will be waiting for results....

 

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