ACCEL 160 lb/hr Performance Low Impedance Fuel Injectors provide precise control of fuel delivery and atomization for increased power and improved throttle response. After all, isn't that what you want in a high horsepower race type application!!! These Performance Injectors are also the new anti-plugging disc type, which will forever eliminate problems that were once associated with pintle type injectors that were prone to plugging due to carbon build up. Benefits: • Provides precise control of fuel delivery and atomization for increased power, improved throttle response. • All-new units, not modified stock, natural gas units or remanufactured from used cores. • New low-mass disc design ensures accurate metering control even at ultra-low and high duty cycles. • Operates at higher fuel pressures without loss of metering control. Great for blown applications where increased fuel pressure and precise metering are required. • State-of-the-art manufacturing processes reduce flow deviations between injectors to improve performance. • Low impedance design for that ultimate control in ultra high horsepower applications. • Can Support up to 2100 HP at 85% Duty Cycle on a boosted V8 running on gasoline. Formula to choose injector size for gasoline powered engines: # Horsepower X BSFC / by Number of Cylinders/Injectors X 1.20 = Required injector size. Naturally Aspirated = .38 to .50 BSFC Nitrous Oxide enhanced = .55 to .6 BSFC Boosted Applications .55 to .6 BSFC 1600HP X .60 BSFC / 8 X 1.20 = 144 lb/hr Injector (I would choose a set of ACCEL 160 lb/hr injectors part number 74160)
