Will the stock fuel system handle a 75 shot of nitrous now?

NoSlow5oh · 02-08-2003

Well, the kits always say the fuel system will handle up to a 150 shot, but its always better to be safe than sorry and upgrade the fuel pump. Most will say 190 lph will be needed. I just bought a brand new 155 lph pump for 50 including shipping, so if you shop around, the upgrade can be real inexpensive. Also when using nitrous, get a fuel pressure safety switch that will cut the nitrous off if the fuel pressure drops below a certain pressure. You can adjust it, but I would set it to atleast 40 psi. With using the fuel pressure safety switch, you could run the stock pump, but I wouldn't recommend it. Thats just my opinion.

ur stock fuel system will handle a 75 shot anything bigger i would get a larger pump

also keep in mind that 1993-1995 5.0L's did not come with forged pistons

TheMolarMass · 02-08-2003

No forged, so what does that mean my limit is?

To be perfectly honost (knock on wood) I'm not worried about the internals of my 5.0 until I hit 400 HP.

i would ask NOS to get the best info they have a very good tech line. as for your fuel system, dry nitrous sytems limit fuel going back to the tank to give you a safe A/F ratio.
