I said myths didn't I? well the nitro blowing your motor isn't a myth but that all depends on percentage, 20% in a meth bottle and then shutting the injection off and letting the engine run the nitro out after the run should prevent it. Watching top fuel guys rip plugs out of an engine frantically flushing it to keep it from going boom is great. If only the nhra had the stones to allow hydrazine lol

Also I am assuming you have a wideband A/F ratio gauge to make sure you have the proper jets, I would recommend one with logging capabilities and you can tune your A/F ratio by swapping jets.

Also if your jets get clogged you will notice you are running lean and could save your motor. Its important to have the proper instruments

How reliable do you think the torque app would be for a/f, it shows me rich now so I don't think I'll be changing anything until I get a tune even them I may just stay with the 75, I would love to show big hp numbers but I have so much wheel spin now I don't see the use for it

Torque is very accurate as the reading you are seeing is exactly what the ECU sees. There is debate that the Nissan sensor isn't accurate and blah blah blah, but your ecu makes adjustments based off the stock sensor not some wideband that's welded in and connected to a gauge.

What's your AFR when you're spraying? Also how does the 75shot feel?

That's good news to me the app actually seems to work really well, I just bought a phone to keep in the car,the afr off spray is reading 13.6 or so on spray it's running 13.4, I didn't mention before that I ran the nitrous line thru the firewall on the drivers side because the additional 36" or so of line will help with lean spike.

The 75 shot feels good it's not throw u back in the seat it anything, more that the car revs quickly there's isn't any waiting to shift I guess

is the zex kit for the 350z the same for the 370z?...i was planing to go dynotune kit!!...are they a good brand to go with?

LNATKFRNG

The one everyone is using from zex is the 350x kit for the later models, from what I can tell zex's attraction is the wot switch is unitized with the soleniods other than that I think there isn't much difference I know there is a lot of brand loyalty, so if your buddies are using one brand and u get another prepare to argue

I am a fan of nitrousoutlet.com. Well made universal kits with jetting rated at actual whp/wtq like NX.

Has anyone tried Nitrous and FI?

megalapagas

Op are you running colder plugs or may I ask what plugs are you running (Preferably part number please) as ill will too go that route but 100 shot?

As I'm staying with the 75 shot I did not step down my plugs everyone does recommend stepping down at 100 though I don't have enough traction with the 75 to even worry about more maybe when the stockers wear down I'll step up in the tires

Finally others doing spray on this car! OP u may want to consider a progressive controller to flatten the initial torque spike in the early rpms and/or eliminate wheel spin when moving beyond the 75shot.

More pics of the layout (switches, bottles, fuel tap, etc) would be nice for others.

Thanks! more solid advice, as I said the traction is a small issue it's wiggly in third so a progressive controller beyond the 75 should probably be done, and yeah I don't see why more aren't spraying their car when like every other car forum is full of nitrous lol

I would tune your kit to run 11-12AFR @ WOT for safety on a stock motor, especially WHEN you decided to move up to 100-150 shot :P
