Minimum Safe N/A Fuel Pressure
Ok guys, I am wanting to program a warning light on my aeroforce gauge to come on when the fuel pressure drops below a certain level. For instance, if I am WOT and the fuel pressure drops below where I am comfortable, I want to know so I can back off.
My problem is, that I can't seem to find a solid answer on what the minimum safe fuel pressure is. Does anyone know? I'm assuming this isn't really a variable answer and should be solid but maybe I'm wrong, so feel free to correct me.

If your dropping below 48-52 you are losing a pump bud.

I'm wondering if what your specifically looking for would not be better acheived by watching the duty cycle of your injectors. If they work up towards 100%, regardless of fuel pressure, your running out of fuel.

Then wouldn't I just be checking to make sure the injectors are able to keep up with the amount of fuel they're being fed? I would rather check on the fuel pressure IMO so that I make sure there is enough fuel getting to the injectors. They could run at 80% but still be starving for fuel.

I did a few WOT runs through 1st and 2nd gear while keeping an eye on the fuel pressure. It did drop down to about 51-52 but it wasn't for long...I guess if I mod anything else I need to get a boost-a-pump or the zl1 pump huh?

52 is what the FPCM commands. Your all good man. If you get sub 50's at wot, the pump is probably showing early signs of failure. On a NA setup like urs, the factory injectors are good to over 600 rwhp NA. The pump will max before the injectors will.
