Power level before needing a BAP
About how much power should an '03 Cobra fuel system support without a BAP?

Re: Power level before needing a BAP
From what I've been told it can vary quite a bit from car to car. At my current power level, the stock system is operating at around 85%. I was told that with my next round of mods, it would be wise to address the fuel issue, for safety's sake.....

Re: Power level before needing a BAP
I was at 516rwhp with a ported blower/2.76" and was fine. I believe you would need a BAP if you went with a ported eaton upper/lower combo though. What are you planning?

Re: Power level before needing a BAP
Only way to truly tell is to get a datalog system on your car where you can monitor fuel pump duty cycle.
FWIW. I bet you are close to maxing out the stock injectors now

Re: Power level before needing a BAP
Correct me if I'm wrong....
But, in the quest for more power, isnt it the pump and MAF that reach their limits before the injectors become an issue?

Re: Power level before needing a BAP
Ordinarily no, but since the stock returnless system raises fuel pressure to meet demand, I think it's comparable to an electronic FMU, which would allow smaller injectors to make more hp than usual.
