Anyone know about NX jets?

I just bought a used NX kit and the jets in it are 88 and 78. What power rating is this? I'm guessing about 200. It is a plate kit for the carbed cars by the way.

well it was either a 275 shot at about 2.7psi of FP or a 350 shot at 7psi of FP, all these figures are a 950psi bpttle pressure.

WOW! I don't need that much. Someone else told me today that it was a 300 hp shot.

Thanks for that site. It's really awesome. My calculations are about 325 hp.
