EFI pump with nitrous I have a 98 Camaro with a carb LS. Car has a stock EFI pump with -6an feed and return. Return style regulator set to 6.5psi. Question is, would it be safe to run a 150-200 wet shot with the stock EFI pump? I know that pump is more than sufficient for a stout carb motor, but wondering if it is OK with nitrous. Engine is an LM7 with forged pistons. Custom grind cam, with 706 heads milled .020 and ported. Holley intake manifold and a 750 mech secondaries.

on my FI pump it's a 340, and it can do it on a smaller shot like 150. Just have to watch the gauge and see. Just remember unlike hi pressure fuel it can take a few drops in pressure and still be safe, unlike low pressure, loose a pound or 2 and its LEAN, See what happens on the hit? maybe up it to 7 1/2 so it drops to 7? I know my fuel card on low pressure has settings for 5lbs, 7lbs and 9lbs.
