Direct port questions. I got my truck up and running. 408, ported heads, 230/230@112, etc. I recently purchased a NX direct port kit 80000EFI. It is a high fuel pressure system but, the jet charts are rated at 40psi instead of 55psi. I was wondering if any of ya'll have this problem. With a 200 shot, I was going to down size the fuel pills from a 14s to 12s.
My best 1/8 mile time is a 7.39@94.98, with a single nozzle and some 150 pills. (This was with no weight reduction.) I have to wait until right before the 60ft mark to hit the juice. I am hoping with the 200s and a better 60ft I will hit some 7.0xs. I will also change from TR6s to some TR7s.
