It's the thumper with a 1.0 ar.


Thank you, also forgot to ask... Is it a cast comp. 106 or billet?

I would like to do twins on a pulling truck and was thinking a Garrett 106mm Thumper for the atmosphere, but didn't know if I should go billet... What kind of RPM does that thing spool at with the S475 primary?

Thanks again,
Matt
