Horsepower Calculator

Do you have our 1000cc high-z injectors? How about our 1120cc low-z injectors? Are you dreaming of upgrading to our 2150cc or 1100 high-z injectors? If you want to know just how much power you can make with what you’ve got (or what you’d like to have) it’s as easy as plugging a few details into our horsepower calculator below:

The number of cylinders in your engine,

The BASE* fuel pressure you will run (your fuel pressure at idle), *our calculator assumes a 1:1 rising rate fuel pressure regulator for turbo applications

Injector flow size – make sure you select cc/min or lb/hr in the drop down, (The amount of fuel you can supply your engine directly affects the amount of power that engine is capable of producing.)

Engine aspiration, {Turbocharged, Supercharged, and Naturally Aspirated engines have different BSFC’s (see Glossary of Terms for definitions)}

Maximum injector duty cycle (IDC) (In order to be conservative, Fuel Injector Clinic recommends a maximum duty cycle of 90%.)
