Today’s question is,, is the stock fuel system going to work?. In reviewing this thread:

FRS has a return less system and an in tank pump and regulator that maintains 58 PSI out bound and I assume this pressure makes it all the way to the high pressure pump. Does this sound correct??

Based on charts in the thread listed above (copied below),, at 58 PSI it should flow about 25.5 gallons an hour. Is this what you guys are seeing??

What I read in the Camaro forums 58 PSI at the LFX high pressure pump should work.

Now trying to figure out how many gallons an hour a NA 350hp motor needs. This seems to be the normal formula:
flywheel hp x brake-specific fuel consumption (B.S.F.C.) / 6) = gph

Based on industry standards the B.S.F.C for:
.
Naturally Aspirated:
Gasoline – .45 to .50
E85 – .63 to .70
Methanol – .9 to 1.0
.
Boosted or forced induction:
Gasoline – .60 to .65
E85 – .84 to .91
Methanol – 1.80 to 2.0
.
(350 x .45) / 6 = 26.25 GPH requirement
(350 * .50)/6 = 29.1 GPH requirement

I’m pretty close to the .45 BSF ,, so the questions is,,, do I really need to upgrade the pumps/regulators for the LFX motor?? BTW,,, no plans for E85 at least initially.
