On my NOS wet kit I'm using a 55 n and a 36 f on 60 psi fuel. it goes from 11:60's to 10:98's consistent. Seems a little lazy coming out and running rich. So I bought a 34 f jet to try but looking at some nitrous calculators its showing a fuel jet all the way down to 28 f. Am I running that over rich? I know NOS runs there systems rich to be safe. Am I leaving a lot on the table? 6 tenths sounds about right to me for 125 or should I be picking up more et. any info appreciated.

I run a 52 nitrous & 33 fuel jet when I run a "125" shot. This is on a 40psi system though. I think most company's run their jet sizes on the rich side.

Also, .6 seems like a good pickup to me considering you're starting at 11.6's already. The faster you go the more it takes to go faster.

thanks, I'll try the 34 F and check the plugs. I'll go 1/8th mile track first.

With 60 psi you should run around a .028 fuel jet assuming everything else is up to par.
