The A1000 is a high-pressure fuel pump. You may observe a very, very minor and momentary drop in fuel pressure when the fuel solenoid first opens, but the drop should be less than 1-PSI, and will recover in about 1 - 2 tenths of a second.thanks Pete 63, I hadn't thought about running off the gauge port. Won't there be quite a bit of fluctuation in the reading of the pressure gauge and will that be enough fuel for the nitrous express?
That's what I said!The A1000 is a high-pressure fuel pump. You may observe a very, very minor and momentary drop in fuel pressure when the fuel solenoid first opens, but the drop should be less than 1-PSI, and will recover in about 1 - 2 tenths of a second.
The restriction in the system is the fuel jet. The orifice in the gauge port is much larger than the orifice in your fuel jet, so restriction to fuel flow is not going to be a concern.
Another alternative would be to remove the 13204 regulator and install a 13202 regulator. The 13202 features an inlet, return, (4) outlet ports, and a gauge port. You're accomplishing the same thing any which way you plumb the solenoid.
Been about a year since I've been down a drag strip, and now ours are getting shut down. I've ran through enough bottles to get a fairly decent handle on the basics of nitrous operating theory and tuning. I've ran a variety of systems on a variety of engines and have been very fortunate to have not hurt any parts due to nitrous use. I'm certainly no expert, and learn something new all the time.thanks for the information I think I'll give it a try. Do you race?
You should have a separate regulator for the juice to accurately control fuel pressure, before I had mine dialed in...it was running crazy fat and I couldn't control it correctly. I think you will find most cars are running lower fuel pressure to the nitrous then the carb or carbs. I would recommend flowing 5.5 psi to start and tune from there. FYI, I run 4.5 flowing on my NOS big shot system with staggered jetting!I breezed right past your original post... Guess I was little repetitive.
