  • Check all fuel injectors share the same part number.
  • Check each fuel injector has the same coil resistance.
  • Fuel injectors are mounted onto flow bench and leak test performed. (30 seconds@5 bar).
  • Flow rate testing at either 2 or 3 bar pressure, 50% duty cycle for 30 seconds.
  • Check spray patterns in a static (wide open) mode.
  • Check spray patterns in dynamic (pulsed) mode at a set open duration and speed.
  • Fuel injectors are placed into the ultra-sonic cleaning tank for a minimum of 30 minutes.

RACE ENGINE FUEL INJECTORS

Race engine fuel injectors, whether it’s circuit or drag racing, spend a large proportion of their duty in the upper RPM range. Therefore, the fuel injector is a crucial and integral part of the engine’s performance. At such high RPM, even the slightest issue or deviation from its programmed operation could cost you the race, or worse.

Depending on the duty requirements of the fuel injector we recommend a clean and a full range-test at a minimum, once per season. But for ultra, high-performance applications we can offer a full programme of pre-race testing.

We can replicate almost any engine / cars data. For example, engines RPM, voltage, fuel used, fuel pressure or duty cycle.

PERFORMANCE ENGINE FUEL INJECTORS

Clean fuel injectors are paramount for top engine performance, fuel economy and engine emissions. If your fuel injectors are clogged and dirty, they cannot deliver a normal dose of fuel and performance, economy and engine emissions are all affected.

Dirty fuel injectors cannot flow as much fuel as clean injectors, which means they are unable to deliver the optimum spray pattern – important for effective engine combustion and horsepower.

In high performance engine applications its very important to maintain, and keep, engines in balance. It is recommended to clean the fuel injectors every 25,000 to 30,000 miles, to keep them flowing at optimum performance.
