One aero 340 in the tank, -10 out of the top of the tank, new holley billet dominator dual pump, 12-1400, rated to 975hp at 60psi. And the 340 is rated at like 400hp. They tee together and go single -10 to the front. It's barely enough pump, when the car was 9.6:1 air fuel the first few pulls, the pressure would rise to about 70# then drop to 65 or so, butafter leaning it out to 11.4-11.6, it was demanding alot less obviously, and didn't drop pressure.

Pretty much, it'll overheat in stop And go traffic if it's above 90* and takes about half hour of it

At night time recently, I it 65* out, it'll run like 195-205

Yea I will eventually go bigger, and mainly bc I need a bigger bore for a better cylinder head. Nobody believes what the 5.3s can do, and do it better than the 4" bore stuff, the heads stay down alot easier on these. We will see what the future brings

No, the largest/biggest/baddest 88mm currently is the Precision X275 large frame 88mm.

Damn that's awesome. I'd love to see the graph overlayed with RPM vs. MPH tho. Any chance you've got that too?

Blwn1. Are those precision turbos the biggest baddest turbos before or after the turbine wheel shears off and flys thru the side of the exhaust housing and or the fender?
