E85 question

[Tech @ BG]

when you get the carb figured out you will need to make sure you can feed it enough fuel, around 240 to 280 gpm , your fuel usage will go up with e85, if you are getting 15 mpg you could drop back to 10 to 12 mpg , but its 105 octane and you can run more compression.

Not sure where you're getting your fuel flow numbers from, and if you're looking at for the fuel pump or carburetor but based on your numbers you'd be looking at enough fuel for somewhere over 100,000 HP.

Mathematically it takes a 1/2-pound of fuel to make one HP for one hour on Gasoline. That would be 1 pound of fuel to make 1 HP for an hour on Methanol. And about 3/4 of a pound of fuel to make 1 HP for one hour on E-85.



240 GPM would equal 14,400 Gallons Per Hour.

A gallon of fuel weighs about 6.6 lbs. So 14,400 Gallons would be 95,040 lbs of fuel.

95,040 lbs of fuel would be able to support 126,720 HP on E-85.

Now you've got to take G-force into the equation, as well as parasitic loss, and the opening and closing of regulators and N&S assemblies. But a 600 HP E-85 engine would want on average a fuel pump capable of flow about 240 to 250 Gallons Per Hour.

Most likely you meant GPH, not GPM.
