Flow Rate Conversion

Use this calculator to convert to and from gravimetric (lb/hr) and volumetric (cc/min) systems of measurement. Fill in either of the fields below.

Fuel Injector Size Calculator

Use this calculator to determine the best size injector for your setup.

Fuel Flow Calculator

Use this calculator to estimate changes in flow rates when a change in fuel pressure is made.

*Brake Specific Fuel Consumption (BSFC) if unknown, can be estimated as .4 to .5 for naturally aspirated, and .5 to .6 forced induction. Consult your engine builder for more accurate estimates.
**Limit maximum injector duty cycle to less than 90% for safe operation.
***Most injectors are rated at 43.5 psi. DeatschWerks recommends keeping your base fuel pressure below 60-65 psi in most situations.
