You reference fuel flow ( consumption) of 290 lb/hr
Is this figure CALCULATED from Injector duty cycle times injector flow rate , or MEASURED in some manner ?
.
Next question is more directed at the Expert tuners/ DYNO operators: Which ON CAR parameter best tracks (approximates) flywheel horsepower:
MAF or Injector flow(duty cycle) ?

My mindset is that Airflow doesn't matter as much as you can have richer AFRs (boosted motors). Using the fuel usage and the correct BSFC should be more accurate.

Yea all nozzles aren’t the same, that’s for sure. I’m def. not claiming to know what other company’s nozzles flow at pressure.
I strictly used the old school DEVILS OWN style wall mount (5 micron) irrigation nozzles. They were all rated at 100psi. (Most irrigation nozzles are). We use to pick them up for $5 each at a garden supply site.

Larger you go on the nozzles harder it will be for the pump to keep up and the lower the pressure will be. (another bonus of spraying pre turbo). Most of those 200-300psi pumps won’t pump anywhere near that with a pair of “larger” nozzles inline. Believe I saw 160ish with twin 10gph nozzles on the devils own “250psi” pump.
Smoke and mirrors if you ask me! Its just a misting nozzle!
Only way to know for sure if you have unknown nozzles and pressures it to flow what you have in a container of some sort and either weigh or measure the CC per min @ X pressure. Make sure to get a pressure gauge with a “snubber” on it as well. Otherwise the pressure is all over the place.

Do u have a build page for this car, from what i see in the pictures it looks to be a c3 vette i could be wrong but those front fenders look very distinctive, if u dont have a build page/forum on it can u post a couple of pics of the car……a boosted LS swapped c3 is a build i wanna do next,
