Quick question on Fuel Requirement Formula

[Xeiros]

Very stupid and obvious question (as I'm sure I likely know the answer already) but the Fuel requirement Formula

(Power x BSFS) x (1 + Saftey Margin) = Pounds/Hour
Pounds/Hour / 7.25 = Gallons/Hour
Gallons/Hour x 3.785 = Liters/Hour

is refering to crank HP correct?

Also, around where would 250whp fall? I was thinking somewhere around 300-310 at the crank possibly.

The reason I ask, is because I just purchase a 14b, and with the stock FP rewire I'm looking at a max of about 300hp with those calculations before my stock pump is max'd out at 140lph.

Just buy a 190 LPH and not worry about it. You can run the stock injectors and FPR with that and be fine

Really? I wasn't aware we could squeeze out an extra 90hp out of these injectors w/o worrying about it. Anyone else confirm that?

The injectors were there the thing I was more worried about. Yeah needing the pump to run 130lph when it's max is 140 is pushing it, but as long as voltage doesn't drop below 13.5v I'd be fine, and that's factoring in a 30% safety margin on calculations as well.

I would believe that you are going to need a bit more for injectors. I usually go off of the Road Race chart to help determine my injector size.

Yeah, I generally consult that too, which is why I had a hard time believing that I'd be fine on stock injectors. We've got 93 octane here, but it's pushing it without upgrading the injectors.
