Fuel Calculator
Find out what flow rate your fuel pump needs for your target power – or how much power your existing pump can cover.
Base Values
These values feed into both calculators below.
Target Power → Flow Rate
How much LPH does my pump need for my target power?
Flow Rate → Covered Power
How much power does a pump with a given LPH rating cover?
Find the right injector size for your power goal – or check what your existing injectors can handle.
Determine Injector Size
How large do your injectors need to be at minimum for your power target?
Power Potential of Existing Injectors
Up to what power output are your currently installed injectors sufficient?
Convert injector flow when the system pressure or fuel type changes.
Flow at a Different System Pressure
Known flow at a reference pressure – how much flows at a different pressure?
Switching to Ethanol / Methanol
How much more flow do you need at a given ethanol or methanol content? Estimated by linear interpolation between the E5 baseline and the E85 / M85 reference values.
