The 12v injector needs 53psi seat pressure to create 300BAR, the 24v injector needs 32psi seat pressure to create 300BAR. A difference of 0.005" installed height alters the opening pressure 30BAR on the 24v injector. So, to achieve the same rate of the 12v compressioin spring, a 24v injector would need the opening pressure set to ~ 180BAR, and this would soley be a crutch. Needless to say lowering the opening pressure to the common range of 12v injectors being 260-280BAR doesn't even come close. Opening pressure can play into the power that can be made with a certain size nozzle, lowering the opening pressure can lengthen or increase duration therefore increasing the injected quantity. However, this will decrease atomization and efficiencey past a certain point. Response is often better with a higher opening pressure, which is beneficial for a street application, even though the peak number may be a bit lower. -

Hp numbers, no need to back them up on another dyno, just put them in your signature, it's the coolest.

1 bar equals one atmosphere or 14.7 Psi for us metric dummys. -
