These injectors flow 60 lbs/hr at 43.5 PSI ( 3 BAR ) and up to 85 lbs/hr at 87 PSI!

In addition, these units are high-impedance so no need to add ballast resistors making them compatible with most engine management systems.

Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed driveability.

These injectors are able to function at high fuel pressures and don't exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures.

Engine performance and running quality are enhanced through the optimized spray pattern. Unlike competitors "pencil stream" high flow injectors; these High Flow injectors utilize a multi-orifice tip providing a true 30 degree spray pattern for improved mixture preparation. This results in lower BSFC and better idle quality than many injectors with less flow.

As used by the Toyota Racing Series for all cars for the 2008, 2009, 2010 and 2011 seasons running E85 ethanol.

Fuel battery compensation / dead time table supplied with each set of injectors - makes tuning a lot easier.
