what a/r is the 42R? the one we are using is alot smaller. than 1.xx a/r but it is a 76mm turbo...a bit larger also.

I was comparing it to the the 42R of joe simpson's and the Super T76 has more of broader power band IMO....its at 800whp for about 2700rpm or so.....

Joe, do you know how many rpm's the 42R produces 800whp on your friends car?
