In for results. 26 PSI? I'll guess 383.

If you were going for an over/under on that, I'd take under, but probably not by much. I can't wait to see what the plot looks like with the calculator I posted up

375 on pump (91) he said he was "limited by fuel" so I'm assuming octane and not his fuel system.

I guess they're gonna do some pulls on "race gas."

He may actually be limited by injector size. IIRC he and I are on the same 650cc injectors. Take that 375hp with a BSFC of .60 and .80 DC on 4 injectors and you are looking at required 743cc worth of fuel. The 60psi base pressure in the NB puts him at 763.39cc for actual injector size. So if you believe the RC calculator, its completely feasible that he did in fact run out of injector.

The numbers listed are optimal, obviously not taking into account plumbing losses and such. I'd have to dig through the thread and figure out if he went boost reference on the FPR or if he stuck with the stock system, because that will have a significant effect on things as well.

Either way, 375 is absolutely nothing to sneeze at

The result is in!

375WHP 319WTQ

This is on a Mustang dyno at 4000 ft elevation. I had plenty of fuel. The power level was affected by timing was being pulled by the knock sensor. The power was around 358WHP when the timing was pulled. The tuner said that 400 is achievable with more timing and race gas or E85 and bigger injectors.



I have videos and logs of the pulls. I'll post them when I get out of work.
