okay guys here is what i got.
I have the GT 6152e 2.5 inch outlet i think has a stepper hose to my rjc FMIC pipes.
here is my combo. I currently have a big set of ported irons with big valves. ported intake with egr delete, a lunati 200/200 cam 1.65 roller rockers, stock TB and plenum with rjc power plate, The block is .040 over with studs in the bottom and top. Fast B2B, the trans has been redone with red clutches and steels with a 9x11 3200 stall( the stall speed @ zero vac is 2650 rpms from the fast datalog.)
the time it took the turbo to go from 2.8 psi to 25.1 psi is 2 seconds. this is a very fast spooling turbo.
I can't imagine a BB version spooling way faster. Do you think this turbo is too small for my combo ?
i have ran a best of a 7.36 @ 96 MPH with the boost 25 in first gear and 22psi in the rest of the gears. I have trouble with my waste gate in first gear because the rest of the gears it stays @ 22psi throught the rest of the run. What could be causing this?
Also on that 7.36 run i still had the stock cam and intake on the engine @ the time.
