Awesome! :tup: but how many sprays per say till I have to change the plugs again?? And

None in my opinion. The least risk is tuned AFR @ (x) bottle psi for any shot combo. If the AFR is off you can melt ground straps, may be damage rings. Do not believe everything you "read". There is a member here that burned up his plugs on 75 shot Zex and damaged a cylinder.

If untuned I would say read plugs after each initial pass ideally. Typically want to spray at WOT then shut the car off and pull plugs. Want to have limited idle time so as not to hide the WOT activity, timing marks, etc.

Lmao no no jo I'm tuning that's fot sure hahahaha its horrying just looking how our engines are and I can't get my hands in there if I'm Dragging lmao....anyways I'm tuning and I'm going for a 100 shot but ill just ask the tuner then as an estimated guess more or less like 3 or 4 passes.. idk just guessing here.....

I think you guys are overreacting a bit much. There is no magic number as to how many times you should check the plugs after each pass. That's why you have UpRev. Monitor your conditions on each pass.

Do you know how long it takes to access the plugs? You have to remove the brace, intake manifold and the throttle bodies if I remember correctly. It was not a quick job that's all I can say. Doing that at the strip will take forever.

This is why I don't usually post because there are a lot of different opinions, or people who no first hand experience, or people who just recently sprayed and have gotten a false sense of security.

Read other forums besides here. Read all the knowledge. Buy all the safety precautions. Learn how to use them, know what they do, know the ranges each readings should be at.

Remember every car has the same risks when going F/I, the key is knowing the limits and knowing the ranges things need to be at. I've ran through more than 30 bottle refills and several passes down the drag strip with no issues for 3 years, take it for what it's worth. GL guys I'm out.:tiphat:

Yes -agreed the plugs are a beeotch to change. Same dilemma on my 350z. I was only suggesting for the first few passes on upon a new install it might be worth it. I say this because I experienced on my 100shot (with uprev tune and standard 4degree ignition retard) that my timing was still too much, and I had black (and slight shiny diamond metallic ) speckling on the porcelain - a strong indicator of detonation. I dropped the jet to 75 to confirm, ran a pass, and had good timing mark and no speckling - then I had my map changed to take an additional degree out.

Sometimes it is better to know what going on outside of blind faith in the tune. To change plugs constantly, yeah agreed not practical.

Nice to see some are N20 on here, albeit the minority for sure - all great info.

So your saying i wont feel at 50 shot at all????

The Z is fast enough for me. Its turning into a weekend car soon anyways.

Just looking for something that slightly feels a bit quicker with out having to worry if my motor is going to blow.

So people are running 75 shots with no tune? Can the ECU compensate for the changes?

Im a noob when it comes to nitrous guys. fill me in :)

That's correct, research your *** off and you will find that folks are running the 75 just fine on stock everything, it's always best to get tuned for any mod especially nitrous, to ensure u aren't hurting anything but the purpose of the wet kits it just that, to keep additional fuel supplied. I suppose you could set up a 50 shot, but IMHO I think would b a waste if time, you ARE going to step it up as soon as you are satisfied that everything is ok! Just go with the 75, and do t spray all over town.....just to say it, zex doesn't even suggest jet sizes equivalent to a 50 shot.

This may not be much help, but I tried the app anyway so lots of wheel spin I tried to feather the pedal to keep it down that I think explains the 13.5et but not the 113.1-1/4 speed

Take any type of app or rating like that with a grain of salt. Track conditions, temp, DA, etc. Play a large role in ET and trap speeds.

Run it at the track as I would like to see what exactly a nitrous Z does at a prepped tracked with better conditions than here.

Does anyone have a step by step instruction on how to set up a nitrous kit on a 370z with a switch and everything?

Hey OP, got any vids man of drag racing etc.???

Still looking for instructions on how to set up RPM switch relay? anyone?

I also bought my nmu from some other than the oem u can down load the instructions from their site I'm sure, as for the zex rpm window switch it was pretty easy just tapped the #1 coil, the WOT switch I tapped at the TPS I'll try to get pictures of those spots for you tomorrow, with your system I don't know if you will have the same set up but I had to bypass the window switch while programming the WOT, if you need that I'll walk you through it. I also found a diagram on the forum of a relay set up that helped me I'll look for it. Also check out the 350z forums they have been spraying those for years and you will find a lot of info

As for videos I have none, I plan on hitting the strip by the end of March with it, just to see where I've ended up with it, I'll post a slip when I do.

Please get me the pictures man. Will give rep :)

Im really interested in setting up a kit but only if i can do it on a RPM window switch.

Any chance on getting pics yet?

Hope they are good enough, the TPS wire I tapped the green wire, used a T-tap so it can be unplugged from the window switch and hooked to a T tap in between the window switch and the WOT switch effectively bypassing the rpm window for programming WOT

The #1 coil orange wire I tapped for rpm

Coil

Get this fuel tap z1 if you don't have one. Don't cut your fuel line

im confused on the first picture :(

Sorry used the phone for them, the first pic is of the passenger side tb I used a t tap on the green wire to pick up throttle position voltage the reason for using a t tap wS so that it can be unplugged from the window switch and plugged directly to the TPS sensor on the zex nmu. You will need this for both initial programming and in the case of dead or disconnected battery

Hey OP, I have the same Intake Setup as yourself, Where did you drill or "Tap" in for the our Dual Nozzles??? I was thinking right after our MAF sensors???? Thanks and can't wait to see vids unless I beat ya to it hahahaha Kuudos!

Isnt this a wet kit?

Do you ever come to tampa man? you are near me! would be nice to see it in person

Mega- zex recommends 6-10 inches from the tb mine are on the bottom of the silicone tubes at about 8 inches I used the same type of pipe reducer to adapt them as most systems use but I used a nut with nylon insert on the inside of the tube and thread locker when u get it tight the profile of both the in/outside part of the reducer is minimal

RW- yes it is a wet kit, wouldn't spray dry on a motor that's expensive.
I do get down to Tampa once in a while next time I do I'll pm it's always good to get to see some other z fans

Mind taking pics of this for me??

btw, how do you program the spray setting at certain RPMS (on & shutoff)

btw thanks for all the info so far- rep

Appreciate the Input OP, That's what was bugging me and didn't want to change intake setup hahaha

Here is the best pic I could get with them on

RW- what type of rpm window switch do you have? The zex switch was pretty easy to set up just two buttons to toggle thru I downloaded the instructions from their site

do you mind backing the camera up? im trying to get a general idea as to were you placed the nozzle :(

If you have the z1 tubes like I have measure 2" from the "z1" toward the throttle body.

k sounds good :)

I was under the assumption you want the nozzles close to the throttle bodies. can anyone chime in on this?

Nope you do want some distance from the tb's but too far and you increase the chance of your mixture "puddling". The zex recommendation was 6-10 inches from the tb I don't think I would go further away than the z1 logo

Is there a dyno on this yet? I want a 100 or 150 shot. What's best route/setup for a 370z?

Try a 50 - 75 shot first. It might surprise you.

You sure? I've driven an 800whp C6 Z06 lol

Long story short....

A dyno tuned 75-100 dry shot. Nitrous cutoff + Window Switch set to open at around 3500rpm and close at around 6500rpm am I missing something? What gears? 2-5?

Never mind... go for direct port.:p

Nah I wouldn't dare with this block. Gotta keep it as safe as possible....so throw in nitrous lol.

What's the highest shot anyone is spraying on here? Hopefully I'm beating that lol. I throw insane amounts of nitrous on my cars
