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.

 

stable track kicked in my tmps light come on and wont let me turn it off. when it does that runs over. track was terrible to.

 

this one i left it in manual mode like a dumbass and it shut down. then i quickly seen the mistake and pushed up in drive.

 

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.
