Zex kit install 100 shot

V8Killer

Sorry for getting back so late, I am still in Afghanistan. Okay so Yes Direct Port is the best way to go but those are usually used for bigger applications around 250 plus which obviously I am not doing. I should have stated running a wet kit is preferred b/c as you know dry kit you only spray nitrous, wet kit you spray nitrous with fuel. I am no where saying I am a nitrous guru and I get your playing devils advocate. What is the biggest shot you have done with dry? In my experience I generally don't hear a lot of people going big with dry kits. It is to my understanding that when you run a dry shot you are betting on the fuel system to compensate on it's own? That means your putting all your trust in the vehicle figuring out what to do once nitrous is added vs the fuel already going in with the nitrous at the same time.Your application is going to dictate which kit to use. I believe that wet kits are safer, and they are also highly recommended and if you ever want to go FI you can keep your wet kit and apply it to your setup. In the end no matter which way you go TUNING will always be the deciding factor.

So just an update, I bought a motor from Z1 b/c well it was easier then going through to see what was messed up in the old motor. I bought a new bottle bracket with a built in heater that will come with a kit to dictate how long the heater stays on depending on the bottle pressure. I will still be going with 150 just gotta find the right guys to tune it once everything is set up. Bought a few other misc. things like a bunch of red silicone hoses, back up light, stealth blinker lights, twm short throw shifter and I am sure I am forgetting a few things. Should have the vehicle running in about 3 weeks. Then back to tuning. Those of you still running nitrous I'm jealous! Has anyone gone beyond 100? Numbers on a dyno?

I think my uncle use to run 150 shots dry on his Z31 N/A(id have to ask him again to be sure) and i did run 100 shots dry on my eclipse before having to remove the kit and sell it(ref ticket) but with the n2o tune i had, it would retard timing and make the car run extremely rich(had 600cc injectors) so when i was spraying, the AFRs were just right

I havent really looked into N2O since then but to do anything with dry kits, you have a **** ton of tuning to do but once its set, it should be just as reliable as direct port(theoretically at least) because each cylinder is either getting enough or more fuel than it really needs, the only reason i say that is because if you went with a wet kit(not dp), there might be a chance where the intake manifold isnt flowing enough fuel into one or 2 cylinders, so those will run lean while the others will run either run just right or rich

dont get me wrong, after i supercharge my Z im going to put a wet kit on but i'm not going to run alot(maybe 50 shots) just because it will require less tuning but dry kits can be reliable if its done right and tuning is spot on


anyhow ill stop derailing your thread XD
good luck with your build, im really interested to see how it turns out

I ran nos on my mustang anything below 50shot it fine dry
75 - 150 wet kit just make sure your getting a good spray pattern with the kit
I was getting lean conditions on the rear pistons and rich conditions on the front pistons because the spray pattern was not that good
Direct port is the best way to go as to not get lean or to rich
I never sprayed below 3k and stopped spraying 500 rpms before redline in case of a miss shift
And because 150shot is like 200-225 additional torque i used a kit to bring the nos on 25% then ramp up to 100%

Just got to stay on top of the spark plugs and your good
