Pathetic dyno results, NA vs nitrous

I've read/heard that some nitrous companies rate the HP gains on thier systems according to FWHP (NOS for example), while others rate the HP according to RWHP gains (NX)... I've never done any nitrous tuning on the dyno... I tune the nitrous system at the drag strip for track conditions and weather.

What was your fuel pressure before you added the 2-3 psi?

And you should make it a priority to get a bottle psi gauge in order to maintain consistency and to accurately log your results in reference to a/f ratio compared to bottle psi... the higher the nitrous psi, the leaner it will run. A bottle heater is a must IMO... again, to maintain consistency.

According to my calculations... I'm getting a full 200hp gain from the wet kit currently being used on my 'stang... to the wheels, that is. Through tuning you'll find your HP gains... I prefer the drag strip (and reading plugs) when it comes to tuning nitrous oxide.
