FAST Precision-Flow Fuel Injectors

FAST Precision Flow 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 FAST precision flow fuel injectors can be higher than other fuel injectors on the market.

It is important to select the correct FAST precision-flow fuel injector that will both physically fit your engine (connector and body type) and match the engine 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. 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).

FAST Precision-Flow fuel injectors are available starting at around $50 each and can reach over $1800 for a set of eight, depending on the type and size.
