Back in '09 I believe my engine builder did 4 LS7's for us... one was for Filip and the other for my car and other buddies. His car is pretty awesome.
We've gone 163mph in the 1/4 with this turbo I have behind a 6.2 liter LS setup and 2900lb car (RX-7) with a 3" downpipe then at the firewall increasing to 3.5". That's well over 1000rwhp. I feel if I dump it at the firewall when I need bigger power and just run it thru the 3" on low power street mode (600rwhp) that should be fine....
I guess I'll have my fabricator weigh the parts I bought and go from there.
