way rich.
way rich. went to the track on my new nx 90 kit. standalone 112 leaded fuel all i had in it. then 93 in the car. c6 auto cam stall
.062n and .035 fuel. 58 psi. within seconds it went 10.0 on my afr . no need to pull a plug i could smell the fuel by end off run. whats would u guys suggest. 40 psi.
and go from there or jet down to .033 and 45 psi. cause its not even in the ball park atm.
its all new setup . i was running a hsw 90 plate and same jets off the rail and it was pretty spot on but had a big lean spike off the hit. holley fuel rails. car was runnin 139 mph about every pass.
got 1 decent hit yesterday . (working on shift points most of the day) and went 134 way way way rich.

I'd turn the dedicated down to 52-55psi and run the 33 jet for starters then adjust fuel pressure from there depending on the AFR. I wouldn't suggest going to 45psi right off the bat and running the 33 jet.

k thats about what a buddy suggested. i know u guys have to make them run safe. i can done tell tho its hits way harder then my old setup. its way more intense. once i get it halfway lined out it gonna pull like crazy.
this is on the way home a quick pull to show my motor vs nitrous afr. my afr gauge is off but i know the guy that tunes it had it at 12.6 on motor and on my gauge its 13.3.
the nitrous pass was at 50% for 2 seconds to 100 instantly. u can see once it gets full flow it goes fat quick. once i get in the upper 11 afr range ill start looking at my plugs and go from there up to a .082 n jet. just needed a closer starting point.
