When raising the base fp up to 50 or even like you did 55, do you have a gauge in the car to watch what it does at redline? or is 10-12psi not enough to worry about it going to high? I know all jr's cars pull off great #'s with not the largest injectors because of raising base fp

my setup is a rotated std 30r .82, with the 2.5i mani, kelford 199-c cams, I should be good with the same 1400 injectors and the walbro 460 hard wired like you pulled off I assume, e85 as well, Im very anxious to see what the larger mani and cams do to my powerband, wondering how far I should rev before power dies, 75-8k too much for a 30r? This set-up was balanced so feel a little better about raising the redline a touch

we ran into %100 on my old sidefeed dw1100's and dw301 fuel pump at 19-20psi, But I dont think I had the fuel pressure set-up correct, when checking/adjusting it, between the line pinched and not pinched, stock fp is 39 and 43.5, correct? do I pinch the line from the fpr or not when I'm adjusting "base" up to 50-55?

The redline is going to really depend on the short block build, the head work and the cams. I have a MPS LR 2.5, built heads +1mm valves and R199B cams. I'm running a Blouch 3.5XTR with the Walbro 465 hard wired through the stock FPC, FPR at 50 psi and IDks. Junior tuned my XTI in December at PnL with some bad/ unbalanced 1100cc injectors. We made 535 WHP/ 490 WTQ by 7 k and 80% IDC's. Now with the IDk's he bumped the redline up to 8k. The motor is 8500 capable. The heads flow well enough for 8500, we're just not sure the turbo will make more power up there! We'll see what she does. I have to run more logs for him when the weather allows. On the road on E85 it makes 28 psi by 3600 and holds it all the way to redline.
