Once you get to the RWHP verses motor your best bet is to climb up on a dyno.
That way you'll know the shot size and you can run a wideband tune.

I believe NX and TNT are rated at RWHP.
NOS is rated at FWHP not RWHP.
Not sure on ZEX, Compucar, Cold Fusion or any other.

Zex IS rated at the FLY.Vry few companies Rate at the wheels. so if u have a Zex KIT the only thing you can do to get the Desired RWHP is to up the jet to a bigger SHOT but becarefull

I Thought NOS was fwhp also but when I dynoed my nozzel kit with the 180 jets I got 175 at the rear wheel, I was really fat in the jetting and that could of made up the extra 5hp. I do know that when I had my TNT f1 jetted at 100hp and then switched to the nozzel at 100 hp there was a big difference. I never got a good dyno with the TNT and never put the nozzel on one with the smaller jets so I cant say for sure, but the SOTP feel was way different.

I recently called NOS for jetting on my combo (kit I desgned for my car). I wanted 180FWHP shot. After doing the calculations on the jet they sugested they must be giving RWHP jet sizes when you call
