How much boost and how hard are you turning it?
Debating just doing this to my 383. Vic jr heads, super vic intake and solid roller(would have to be swapped) and going to e85 blow thru.
Would the gt4788 make more power?
I'm running 22psi and 6500rpm .
C-16 at the track and timing locked at 36º pulling it back to 26º at 22psi
AFRs are 12:1 ...... Using Water / Air intercooler , AITs in the hat are 100º at the top end . Compressor temps are 300º + .
