ATI super dampner

I hear those Rattler are awful after 7,000 rpm's. Up to 5,500 or so they work very nice.

Some crank makers claim Rattler dampers snap off crank snouts.

You think it be easy to make great dampers but doesn't seem like it.

I hear Nascar teams tested them (read 9000+rpm) and wanted to run them but because of the moving parts in them Nascar banned them. This is from a P/S tuner in Ca.
This guys know's his $hit and has helped a few teams this year with their engines.

Only way to know FOR SURE is to test yourself otherwise it's just hear-say.
