FAST Precision-Flow injectors are your best choice for fueling your hot rod, race car, or anything in between. These injectors are precision flowed and sorted to ensure that you get consistent fuel delivery at all pulse widths and duty cycles. FAST Precision-Flow injectors are dynamically, multi point tested, and sorted in sealed sets of 8 with a tolerance of +/- 2 percent at all points. This flowing and sorting process gives you consistent cylinder to cylinder fuel delivery for even Air/Fuel ratios across all cylinders and accurate fueling. Your engine gets the amount of fuel it needs to each cylinder for smooth, reliable performance. Full injector characterization data is available for each part number. Features: * Dynamically flowed at multiple pulse widths, then sorted and sealed in sets with +/- 2 percent maximum variance * Include large LS style lower O-ring but can be used in applications with a 0.550 in. injector bore by swapping lower O-ring * Available in flow rates from 30 lbs./hr. to 245 lbs./hr. (rated at 58 psi) * Available as singles or sets of 8 * High impedance * Compatible with ethanol and oxygenated fuels * Part number and flow rate etched into each injector for easy identification * Complete plug-and-play characterization data available for most OEM and aftermarket engine control systems
