Saw Holdener thew a n* stsv blower on a 4.8 and made 600 on 11ish psi. The gt500 m122 I run and the stsv blower run the same rotors I believe.
I have 10 psi on my setup with the 2.75" pulley where he has 11 on a 4.8 with a 3" pulley. I have my 2.55" pulley sitting on the shelf I haven't run due to chassis (rear end) issues we're all aware of here....
I have 70 cubes on top of his test.
It's a bit apple to oranges but he ran 23 degrees of timing on E85, and I think I'm at 16 before I 'naded my diff last fall.
If I have 70 cubes and 7 degrees roughly on the table, I might be tapping on the door to 700hp. Almost a bit freightening....
I know 'if wishes were fishes' but damn, those are some stellar results. +30hp on corn without timing adjustment.
