So l'm guessing it's not a wet kit? Wet kit is a plate. The wet kit bypass the carb an runs full on 7psi that the mechanical pump puts out with the nitrous when the solenoid hits.
As for timing l ran mine at a solid 38btc without issues but my heads(exhaust guide and springs) and internals(forged) were meant for nitrous/turbo or blower.
An infact it was a 468, but that was 10 years ago.
Oh an l had 2-250 plates but l never hit the second one. Nitrous is fun but it gets old soon.

I’m sorry it is a nx wet kit plate

So basically with the fuel solenoid I do not need to worry about what my carbs running as Long as it’s tuned correctly the fuel solenoid will take care of the rest

I have a buddy with a 408 stroker on juice that has done extensive testing on his car. It's been 9.70 @ 139 on pump gas with juice, 10.58 on motor. He still hasn't thrown a bunch at it, BUT what he found was that most of the recommended fuel/nitrous jet setting from the manufacturer are reversed to keep them safe. Reversing the jets to lean the fuel out made it quicker.....
