Different fuels and engine configurations change the amount of fuel required to produce a specific amount of engine power.  The table below indicates most of the variations of fuels and engine setups.  Choose the engine and fuel type that most accurately matches the engine set up in your vehicle.

NOTE: Most supercharger applications require a large amount of power to run the supercharger.  Consult with your supercharger supplier for the amount of power your supercharger will consume and subtract that amount of power from the table below.

NOTE: All Power estimates are for 3 Bar of Fuel Pressure, and are HP and KW at the engine.
