Fuel Calculator

Formulas used by the calculator are taken from the Aeromotive Technical Bulletin #501
Use the following information as a guide. The actual BSFC can be determined through flywheel dyno testing.
Naturally aspirated engines are normally most efficient with a BSFC between .4 and .5 lbs/hp/hr.
Nitrous combinations use a little extra fuel and often develop a BSFC from .5 to .6 lbs/hp/hr.
Forced induction engines are usually least efficient and BSFC ranges from .6 to .75 lbs/hp/hr.

The formulas used in the following air filter calculators are based on the information in the K&N Filter Facts page.

A K&N filter minder can be used to monitor the filter restriction.
