BSFC for one horse power per/m

Hello People,
What is the BSFC for one horse power gal per/m.
Trying to calculate how much fuel a 1500 gas engine consumes

0.5 lbs of fuel per hour per horsepower...

It all depends on how efficient the engine is: total combo carb,intake,compression ,cam and exhaust. A BSFC of .50 ( 1/2 lbs fuel per hour per HP.) 800 hp engine would need(consume) 400 lbs of fuel in one hour at a BSFC of .50 or 66.67 gallons assuming VP C-12 with a specific gravity of .717.
But if the same 800 hp engine has a BSFC of .390 the fuel needed would only be 312 lbs or 52 gallons in one hour with VP C-12.
Assuming a BSFC of .50 is safe any performance engine should be able to achieve that number.
What is the engine ?

Hello People,
Just wanted to let you know that I found the info in detail,
Use a calculator and plan on .5 lbs/hp-hr. (gasoline). Methanol alcohol requires about 1.0 lbs/hp-hr. Use .7 lbs/hp-hr when planning a gasoline system for nitrous assist.
EXAMPLE: You have a 650 hp engine. 650hp x .5 = 325 lbs/hr. (gasoline). Although you need to know how much your fuel weighs, assume for this example that it weighs 6.2 lbs/gal. 325 lbs/hr. ÷ 6.2 = 52.42 gal/hr. Dividing by 60 (minutes per hour) yields .847 gal/min (GPM).
:idea:

10 gallons per hour per 100 hp. 150 Gallons per hour. Divide by 60.

10 gallons per hour per 100 hp. 150 Gallons per hour. Divide by 60.
That would be a BSFC of .6 I'm not going to say that would be a two stroke but it certainly wouldn't be much of a performance engine or if it were it would be running awfully rich. Maybe a pain ass stocker.

SleeperI wouldn't want my motor to run there, but for purposes of figuring a fuel pump, I think it's definately safe.
