Foose + little Nitrous...730HP/747TQ
Red got strapped to the rollers today to do some tuning/testing. Have to say,Truck performed just as GM intended 
(poor thing) 10+ 600HP pulls to 150-160 MPH in third. Only real issue was I had some issues loading the dyno and could only make 16.5psi on boost only. I know it's a load problem though as I can make 20-21psi on the street/track. In any case, that 16.5psi made a best of 627HP/650HP.
Next up was a 35 dry shot at 750psi bottle pressure. Truck picked up boost to 18psi and made 699HP/720TQ.
So close to 700, I wanted it. So we heated the bottle up to 950-1000psi. Hit it again, bingo 730HP/747TQ. She likes the cold air!
Love the TQ, how about 747TQ at 4800 on a 293ci engine? What!??
Basic setup is:
4.8L with....
KB racing 76mm Kit, with a Extreme Turbo Systems intercooler
02 LS6 Cam/PAC 1518 Valve springs
Ls9 Gaskets/ARP studs
E85/80lb injectors/2 Walbro 400 with BAP at 17.5 volts
Dry 35 Shot
JakesPerformance 4l80/Circle D tc
Good times!
