so i took my car to get dyne tuned, they called me and said i didn't have enough fuel :shrug: on the dyno the pressure would start at 60psi at 3k-ish then drop while rpm's were climbing ( 4k 50psi, 5k 40psi and 6k-sih 30psi). i could actually hear where the engine was struggling to climb rpm. i have stock fuel rails that are hooked up to a fore innovation pressure regulator and fore innovation fuel hat. i would think this is enough fuel, the tuner told me that it could be my fuel rails or a bad pump....im leaning towards a bad pump.
here is my question, how much fuel pressure will the stock 03 cobra fuel rails hold before needing aftermarket fuel rails? how can i test the flow on a fuel pump?
- e85 fuel
- 2 walbro 450lpm pump
- kb boost a pump
- ported eaton
- 2.76/4lb lower
- 80lb injectors
- sct ba2600
- accufab plenum and tb
thanks in advance
