Default Re: Fuel Injectors / Rail
per HDDP...

"I finally got the specs on the SRT6 injectors from my SPY at Bosch I must say, they have a HUGE flow difference from the NA engine and now I have to figure out how the SC engine is regulating the flow, whether by pulse width or pressure regulator.

NA ENGINE: 17 lbs/hr at 3.8 Bar, or 55 psi/ 14.5 ohms.
SC ENGINE: 51.6 lbs/hr @ 55.1 PSI / 14.5 Ohms based on 380 kPA = 3.8 bars = 55.1 PSI

But, this leads me to wonder if the NA engine would benefit from an injector swap..."

So the SRT6 injectors are WAY TOO BIG to run on a regular naturally aspirated motor.
What I'm still looking for is the Bosch/M-Benz part number of an injector which will flow
SLIGHTLY MORE than the OEM Crossfire injector. Something which will take us from 17 lbs/hr up to 22-26 lbs/hrs of max flow. The 3.2 SOHC V6 was used in some big sedans and in a SUV application. Perhaps one of those part numbers will work. Do I need to start trolling in the M-Benz forums or does anybody around here have an answer ?
