Did you know all Raceworks injectors are dynamically flow matched?

Raceworks injectors all start off as a genuine Bosch EV14 injector. They are all compatible with and warranted for use with Gasoline, Ethanol and Methanol/Alcohol based fuels, for 2 years.

All Raceworks injectors are statically and dynamically flow matched. This is done to accurately replicate their operating conditions in a vehicle. The n-Heptane test fluid is temperature controlled, and the injectors are preconditioned with 10,000 pulses, before being statically flowed at 3 different fuel pressures. They are then dynamically flowed at the same 3 fuel pressures, but with 25 different pulse widths. The injectors are also flowed at 10 different voltages, from 6V-15V respectively. What is most important is the set of injectors aren’t pulsed at the same time, as is the case with many inferior Injector Flow Benches. Pulsing at the same time causes a pressure differential through the rail and isn’t an accurate representation of their true firing order.
