Holley Fuel Injectors

Holley fuel injectors are made from high quality components and assembly making them very reliable and consistent, along with providing long service life. Due to the high quality, the price for Holley injectors can be higher than other fuel injectors on the market.

It is important to select the correct Holley fuel injector that will both physically fit your engine (connector and body type) and match the engines fuel needs. Once the physical fitment is confirmed, the fuel injector size has to be determined. This is based on the amount of horsepower of the engine, number of fuel injectors, induction type (normally aspirated, supercharged, etc.), fuel type, BSFC (brake specific fuel consumption), and injector max duty cycle. The Holley fuel injector calculator states that injector size (in cc/min) is equal to the (estimated horsepower x the brake specific fuel consumption (about .50) x 10.5) divided by the number of fuel injectors times the duty cycle (typically .80).

Holley fuel injectors are available for $50 each and can reach just under $2000 for a set of eight, depending on the type and size.
