He probably had some sort of progressive controller for it, although still should have had some sort of HP rating on it. N20 definitely requires good fuel pressure and an upgraded fuel system if your running a decent sized kit.From what I understand (and what I remember), it has to do with even the best N20 systems having a tendency to run lean and aluminum heads are supposedly a little more susceptible to warping.
Also, he didn't run N20 with a "shot." He turned it on and from what I remember, it was setup kinda like fuel injection. Timed injections dependent on engine rpm.
Progressive, that's what Mike called it. John's car was the test car for it. I'm not sure if they ever worked out the fuel mixture though.He probably had some sort of progressive controller for it, although still should have had some sort of HP rating on it.

guess his test car didn't work out so well :BangHead:Progressive, that's what Mike called it. John's car was the test car for it. I'm not sure if they ever worked out the fuel mixture though.
Freak, the solenoids do not open gradually. They are either open or shut, never partially. If there is an electric current flowing through the coil, the solenoid will open. A progressive nitrous controller sends a 'pulsed' current to the fuel/nitrous solenoids, thus opening and shutting them.guess his test car didn't work out so well :BangHead:
a progressive controller basically just gradually opens up the solenoid, so you don't get the whole shot at once...works better for traction and a little easier on your drivetrain.
Agreed on the tune. I'm glad to hear the bottom ends can handle a 150-200 shot.Nowadays having nitrous without some tuning is usually not a good idea.
For some reason they'll run lean on the juice, and lean + nitrous = BOOM.
A stock LS3 should be able to take on a 150-200hp shot without modification.
However anything more than a 50hp shot, and I'd certainly want some kind of tune or controller so it doesn't run lean.

Yes, although we're only talking miliseconds, it does have the ability to 'feather' the shot up to the point of full spray.OK.but it produces the same effect, I assume.
