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 ?

Wanted to bump this thread again.

I'm confused..............

You are all saying that the injectors on our NA Crossfires run at 17lb/hr
but as far as i understand our bosch injectors which i know are smaller than the stock slk320 actually run at approx 160cc which equates to 15.5lb/hr.

if this is true where are you getting 17lb/hr from??
