Chris Moore said on this bike they have a 1 gallon tank on the front rack and an external pump under the seat because the lines give extra volume.
Do you know what fuel pump you’re going to run?
You can calculate the Brake Specific Fuel Consumption, BSFC. The formula is
BSFC x HP = Pounds of fuel per hour.
Aeromotive says methanol is 1.8-2 lbs/hp/hr.
2 BSFC x 400 hp = 800 lbs of fuel per hour
800 / 8 injectors = 100 lbs of fuel per injector. This is the flow rate required for each injector.
That seems like a lot of fuel to me so I’d go on the side of having a slightly larger tank.
This is the math that EFI University is teaching to size injectors. I’m curious to hear how that aligns with the experience of someone who uses methanol.
