NX jets: 50-shot 35N/20F 75-shot 41N/24F.

Fuel pressure = 43psi. from the FSM.

That's a handy little calculator that Krazy6 posted in another thread. Its very helpful to be able to calculate whp and what fuel/nitrous jet to use.

Thing works like a champ!

It also tells you the crank hp gain and wheel hp gain.

If you run the NX jet sizes I posted here through the robot, the robot's numbers do not agree with the NX power gains. I have dynoed with those jets and I can verify that the WHP is as stated by NX.

Grey99's next dyno in KC - with nitrous, 8-9-08


Beware of the Robot.

It's not gonna be 100% accurate. The main purpose is to get a ballpark, and then adjust with the fuel jets to get the a/f that you want.
If you don't make the power you want, go up on the nitrous jet. lol

Yeah, but.... A/F has nothing to do with the WHP for a jet combination. I'm saying those calculations are --- off....

This one is good:
