this jetting too rich??

I have a NOS kit on my firehawk as of now with a sigle nozzle setup. I am currently switching it over to dual nozzles as I have maxed out just using the one. I am jetting it 51N/40F in both nozzles (was told this is going to be a 150 RWHP jetting setting) . My question is this going to be too rich with bottle pressure in the 950-1000 psi range???

51/40 is way too rich and 2 51 jets is like a 200-250 shot.

Just for reference, 62/33 is a 150 shot on a single nozzle.

You'll be lucky if you car runs with those jets in your car.

I was told that those jets are for a 175 shot which will equate to about 150rwhp by a NOS tech rep when i called their tech line. It seemed like it was a little much to me and i even asked him if he is sure that is correct like 3 times and he insured me that on my car with dual nozzles that i need 51N/40F. i dont know, thats why im asking.

qty 2 51 jets should be around 200hp, but maybe the NOS guy was right saying 150 to the wheels, because of all the black smoke dumping out the tail pipes from the 40 fuel jets.

Ask another NOS rep, see what they say. Also I see they visit this board from time-to-time, maybe one will chime in.

*Also important* what size solenoids do you have?
