Bad ***! You are right! It’s timing and tune!

I'm 10.6 to 1 with 20 psi I can run 50% ethanol and no meth with no issues. I only added the meth to experiment with it and then fell in love with the benefits. You will not get over 20 psi on that motor with the F1a. I'm only a 377 with stock heads spinning an F1a-94 to max recommended impeller speed hitting 20 psi. These can safely be spun higher and probably gain a little more, but with that motor you have it's going to be more efficient than my little motor with crap heads so you will not get over 20 psi out of that blower on that combo.

Like mentioned it's the tune not the boost level. Too much timing for the combo and yes you will have issues.

What does the fuel system consist of ?

TrendSetter

it looks like the blower inlet is up against the radiator where its only going to get 200 degree air

Yeah; I have an original pro-charger hat, with a large cut square hole on the bottom of the hat to let the blower breathe.

Had this set up on the last motor. Blocks all the hot air from the top and lets the blower breathe. Cold air is taken from the bottom.

Hot air is blocked from the top.

When is the dyno scheduled? I'm curious what it puts down. I'll guess 1001 rwhp.

Line lock is getting installed, and some other last min details. I think next week we may be able to get her dynoed..

1000 RW would be cool!
