Need a check on my Nitrous Barracuda setup

I tried the the setup I had, did 3 hits. One in 2nd gear and two in 3rd, seemed to do pretty good. Broke traction in second tho gonna need more tire.

Might be pushing it with the 93 octane.. but your static compression isn't crazy high. Other than that, everything else sounds shiny.

Yeah I was a little worried with about the 93 octane, I wound up putting a can of that race gas octane booster in and it seemed to do good.

I would top it off with a splash of 110 leaded until you get the hang of things.

You need to switch the plugs out to a non projection tip. I would have to look up the number for a 5/8" extended reach plug. NGK is your best bet.

I would waint to turn the kit on until at leasr 3800 rpm. You don''t want to lug the engine spraying. Turning the kit on at too low an rpm is a recipe for disaster. You don't want a nitrous backfire and definitely don't want to beat the main bearing out of the block.

Target AFR on spray is going to be more like 12.8-13.2. 12.0 is way rich spraying.

What are the ring gaps set at?

I have a photo of the plugs I have in there, I feel like they are non-projected. When I checked them right after the hits they had an orange coloration to them, except #8 and it looks like the one in the picture. I can't use leaded as I have O2 sensor would VP MS109 be good? I will work on the tune and bring the NOS on at 3800 seems like a small window (3800-6000)? and I will take closed loop to 12.8 AFR. Think I should tighten up the NOS AFR limit cuts to a more narrow band? Engine was built with NOS in mind, forged pistons,.030 ring gap and floating wrist pins.
