I'm adding a nitrous system to my car and I'm wondering if anybody here has used this plate, it's a 4150, high hp plate, lowest it goes is 150. Chart says to use 65 jets square with 9lbs flowing fuel pressure, anyone stagger the jets and run less fuel pressure?

It is a older plate, Shows a 65 square for the 150 shot, 73 for the 175, says to have 8.5-9lbs flowing fuel pressure on pump or 7 5 on race gas. I also have a standard cheater plate that I know you normally stagger so may run with that, But was curious about this pro flow plate.

Square jetted w/ that much fuel pressure is gonna be really rich. A 10 jet spread (fuel smaller) at 6 psi is a good start point.

Its been about 20 years since I juiced my car, and always used the 8-10 spread on a cheater plate, so when I got this and it showed square with that much pressure, I was a little confused. My Cuda is a mid/high 10 car,and is heavy, going to hit it with 150, see what it does. I'm putting this on for a event at Pomona next month, always wanted to run there, and its normally only open twice a year for the NHRA races, so us street guys are SOL. Thanks for the advice and heads up guys...

Lots of tune ups thrown out here, no one taking into consideration what nitrous sol is on this kit, what orifice size and what feed line etc. the sol orifice plays a part in the overall flow of the system.
That said, follow the tune up and be prepared to lean it out, either .5lb at a time or 2 -3 jet sizes on the fuel side.
Or the best thing would be to send it off and get it flowed. Induction solutions or PKRE. Getting it flow mapped is money very well spent as you will have a professional to help you after the sale, and they will help a lot !
....BAD A$$ STREET CAR.....

I have the standard #4 trunk line, #3 from solenoid to plate, I'm leaning towards using the Cheater plate, as I have used them in the past, and used a 8 jet size jump between fuel and the nitrous, plan to only run a 150 shot. I have never used the ProFlow plate, so the orifice size and their chart wanted 9.5psi flowing on the fuel side made me a little concerned. I am running the car at Pomona next month, I won't be able to get to a track beforehand, maybe a pass or two at the local street race spot, and see what the wideband says. I'm also installing a Dana, should be finished this weekend.
