I have a question for any of you currently using nitrous. I have a crate 535HP 460 from Ford Motor Sport with a NOS Cheater. I have installed it exactly how the directions state, with two fuel lines coming out of the fuel regulator one of course the the Demon 850 and the other to the nitrous solenoid. A few different self proclaimed experts at the track assured me when I hit the switch the car is going to lean out and those aluminum heads will fit loosely in a 5 gallon bucket. I have an MSD 6AL and an MSD timing controller with the correct timing retard chip for the 180HP jet. I have one colder range plug and as soon as summer gets here I will also have the racing gasoline that is required.

I spoke with NOS and they've assured me it will be fine but the "experts" say I need to run two pumps and two regulators.
Isn't it Bernoullis principle that pressure is equal on all sides? 6PSI coming out of the regulator is the same in both lines. Is it because one line experiences a pressure loss (solenoid) due to an increase in volumn?
Any thoughts
