i need your help guys
I just ordered a nitrous outlet plate kit

car is a 91 mustang with ls1 6 speed it made 445rwhp n/a and I plan on spraying it a 150 shot

currently running a 255lph in tank pump into a corvette regulator with no problems

I was looking at either buying a 340lph aeromotive in tank pump
or a dedicated fuel system..
I need all the info I can get guys please chime in

i have the same exact car and setup, 42lb injectors, 255 in tank and 150shot put down just about 650rwhp with no fuel issues at all, i have an aeromotive 340 now because the old pump burnt out, otherwise wouldnt have touched it

OK thanks man..I'm gonna order a 340 just to be safe
Did u have a fuel pressure safety switch? If so what psi does it need to cut out at?

Glad to hear about the plate. If you need anything fell free to contact us about any questions.

The 255 pump is usually good from around 550 whp.

also when i swapped my pump i picked up a 94-95 fuel pump hanger because it has a 3/8 feed and 5/16 return

I think you would be fine with just running it off the tank. now if u had two stages then i'd say do a stand alone

I ordered a f body specific nitrous outlet plate kit.
Its in a mustang with-6 fuel line and corvette regulator. Will the 340 stealth pump support 600+rwhp

i have -6 line and vette filter w/ the 255 @640 rwhp, another friend of myne has a very similar set up with a 255 as well around 650rwhp, i highly doubt you will have fuel issues on a 150 shot
only perk of the 340 pump is its quiet as hell, almost cant hear it, and im sure it will flirt with supporting about 750rwhp but that depends on the fuel and motor setup
