after getting everything back together a 2.65 pulley on the procharger D1-SC and 80 # injectors...I got it drivable and started doing some pulls...
I Hit 23#'s of boost @ 3500 rpm's going to be a killer set up...

My last set up was 3.10 pulley and 62 # injectors...did 512hp, 14#'s@6000
this set up will be limited to 5350 rpm's what do you think the #'s could be..

Is it rpm limited because you hit the max blower RPM of the D1? That's a pretty crazy step up in blower rpm

Where were your peak numbers before? Will you be cutting it off at the knees shifting it so early? I may have taken a slightly smaller jump up in order to let it rev a little higher but thats just me.

I not concerned with it revving higher...sbc is usually bullet proof to 5500... max impeller speed of the blower is at 5350 so I decided that's were I need to be..
my peak numbers before were never reached because we maxed out @ 6000rpm tuning software max for the ecm
