I'm wanting to step up my game a little,....and I need some GOOD advice on my N2O set-up.

Currently,.....
My engine is as follows,...
598"   14.4:1 compression
A-460 Heads (18-bolt) stock un-ported
A-460 new style Intake Manifold (slightly ported WITH Cloverleaf still intact)
Quick Fuel 1450 Carb
NGK -9 plugs
116 Renegade Fuel

Engine in N/A form made,.... 995hp @6500, 859tq @5900

My truck is HEAVY,.....around 3800lb w/ me in it.
Runs in the upper 5.80's @ 116 N/A,......and on a baby shot (100hp N2O),....it runs on the low end of 5.70's @122  (best of 5.72)

I'm currently using a Nitrous Express Gemini Twin Plate kit. http://www.nitrousexpress.com/60070-10-dominator-gemini-twin-stage-6-50-100-150-200-250-300hp-with-10lb-bottle.html


The truck has a MSD (6520) Digital 6 Plus ignition,.....which I'm using to pull timing out on the hit.  Initial timing is (Locked) around 34 degrees total,.....and I'm pulling 6 out through the box on the 100 shot.   Tried 150hp jets,......pulling 9 this past weekend and the truck didn't seem to like it.   Pulled the plugs,......and nothing looked out of the norm.  (And honestly,.....I'm not worth a shit at reading plugs,....LOL)  ANYWAY,...I replaced them with new,...and went back to the old 100hp tune up and it did fine.

I'd like to ease into a 200 or 250 shot,........BUT,... I'm not sure if I should keep this NX plate,....OR,.....switch to different one,.....perhaps from Steve Johnson.    I've also been considering a Fogger set-up,......but I don't know if that would be overkill for what little nitrous I want to use,........Not to mention it's more expensive and have to deal with the hassle of removing the manifold and sending it in for the work.

Any "GOOD" advice and/or suggestions would be greatly appreciated.   Wink

A plate system will support 200+ HP easy. I would pull the timing down around 22* and C14, nitrous plugs tune from there

Are you using a progressive controller, or going with a "full hit"??

you say the truck didn't seem to like it, what did it run? you could be running into a situation where as you go up in the jet chart the nitrous mixture gets richer. don't be afraid to lean out the nitrous tune, too rich can hurt the motor just as much as too lean IMO even more so. What was your total timing at?

There are a few things I don't see mentioned. How is your fuel system supplying the fuel side of the nitrous, and at what PSI are you running? Suspect What jets are you using and the spread N/F? I am guessing you are just using the canned tune that came with the kit, the kit should easily support what you want to do but the tune is everything. I would focus on the fuel side, and rather than changing the kit, send it to Steve at IS and have him flow the kit you have, or sell that one and buy one of Steve's kits and get some proper tunes for your application.

I know this is an old post but from the size of a bbf intake I would switch the plate to a single entry NX RNC plate. Your current solenoids are probably fine. If you need anything hit me up, 903-870-8109. We flow and tune nitrous every day.

Induction Solutions X-275 Direct Port kit.   I had it flowed from 200 to 500.

Should be a hoot,....after I get it installed & dialed in,....
