Finally got the truck putted back together and torrie did the tuning. Couldn't be happier. She exceeded our expectations. Final number was 830hp 893tq @10psi on pump gas. Shes is a handful on the street. Super happy with the truck now. Track #'s coming soon.
Man, your beast sounds like you did everything right. Thinking about some of the same treatment but at 71 am feeling I probably have all I can handle. Good luck and do keep us posted.
I have a larger crank pulley. I believe its 8.25 inch. Im in the middle of re doing my fuel system. Then another tune and off to the track.
Nice. I'm hoping to get to those numbers with mine when I get it tuned this summer. I ended up doing a custom dedicated belt drive. I'm hoping to be around 10-12 psi "fingers crossed". If I get her into the 8xx rwhp I will be very happy
After talking to the guys Paxton im already at max impeller speed with my set up. Any more than 10psi and you will risk blowing the seals on the headunit itself. Plus your gonna be dealing with belt slip. Right now im running a 112"belt. But i added 1inch spacers to the ac compressor bracket to pick up the slack from the tensioner. So far i have zero belt slip. Fingers crossed. I'm also in the middle of redoing my fuel system. I was only running one 525 walbro. I didn't think i would pass 750hp. At 800 the we started loosening fuel pressure. Im going with an additional walbro 450, some fuel rails from justin at jmb on a return style set up. Then a retune maybe next month.
KOOL! Already have the forged lower end, 4 degree adv. crank gear, Comp cam, ported heads, manifold, headers. Crank keyed, clearanced, ready for Paxton/Novi. What LB/Size injectors are you using? [email protected] Need your engine built? Calipers fixed? No drag!
