Zex is the safest. NX just tells you how much your putting to the wheels.

zex is by no means the safest.

Why not?

 

Zex is booty. Go NX.

Come on guys, give reasons why. Don't jump on some damn bandwagon and talk **** without backing it up. I say ZEX because of the throttle switch. The nitrous kicks in a few short feet out into the track giving just enough time for the slicks/drag radials to hook. It is also the safest and most consistent kits because it regulates fuel pressure according to nitrous pressure. The only thing I can find wrong with the ZEX kit is that it's shots are rated at the flywheel, not the wheel, but who cares? Just go with a bigger shot if you're not satisfied with the WHP.

 

i am running an nos wet kit wit no troubles. the nx kits have a great rep though. the hardware is supposed to be much better than nos. i like zex for ease of install, cleanliness, but i would prob go nx for upgradability.

What do you mean by upgradability?

 

I dont like the purple box setup where it runs off bottle pressure. bottom line is it runs of your injectors cause its a dry shot. suppose the box fails, peace out motor. i like a good setup wet kit where it run off n20 and a separate fuel source. i would never run a zex kit on turbo car. its like the venom kit where it runs of the box. its supposed to be the safest out there cause it detect lean conditions and shuts off the n20 if it runs lean. problem is if the box fails, peace out motor. if you run a good wet kit the variables that can fail are much less. if you learn how to drive the car with nitrous on the button, you can have it come on anywhere down the track for traction and then if you lose traction you can let off the button and get back on it. NX is the highest quality kit i have seen yet in my opinion. wet kit also hits much harder.

Peace out motor if your fuel solenoid fails. Same thing, ZEX box is just a fancy solenoid. With a dry kit all you have to worry about really is your injectors and fuel pump. With a wet kit you have to worry about injectors, fuel pump, and fuel solenoid. So if you think about it, there are more variables that can fail with a wet kit.

 

I don't like turbo because if your wastegate fails, peace out motor.

I don't mean to mock, but that is really what I'm reading from all this. If you have something bad to say about the Zex kit, tell us what is wrong with their industrial suppliers of solenoids, LM2907, and LM339 that go into their kits.

Wet kit or dry kit, it's like a hat you wear. What sort of hat do you like?

I've got a DIY NO2 kit sitting on the floor here, complete with RPM window switches and DSM 450cc - gonna switch ECU chips via high speed relay for alternate fuel and ignition maps. I've even got it down so that the fuel flows a few ms after NO2 is shut off, as I'll be injecting the NO2 in front of the throttle plate a few inches away from the injectors.

On a side note, anyone ever play with water injection and NO2?

 

Nope, never tried water injection and nitrous. I'm assuming you're using a dry kit if you're upgrading injectors and using different fuel maps for on the bottle. What size shot do you plan on running with your setup?

 

It's going to be for the 89 DX hatchcrap, have to swap in a D16 and go for it.

I'll start with the usual 50 shot, and see what water injection does to the EGTs. Based on how that works I'll move on to a 75 or 100 shot and try to **** the bottom end.

 

Sounds, like fun. So it is a dry setup then? The D16 bottom end will hold on to 75 shot for a long time, but 100 shot is risky, might not hold on too long. I am building a stronger D16Y8 bottom end to safely run 100-125 shot.

not if you are watching your boost gauge anyway, if the zex kit is so great why is not one car running in any pro nhra class running it?? the nx kit uses the bigger pro fogger like the big shot nos kits. they dont lock up. it is a dummy proof kit yes but not the safest sorry.

 

So I should use a BFH (Big ******* Hammer) for those little itty bitty problems? I need the ability to run a 250 shot on a stock D-series?

Mike, you're a great guy to know when it comes to building obscene power. You're also fairly out of touch with reality when it comes to what the regular enthusiast wants or needs... not that I am either on the other end of the diehard DIY or die spectrum here, so I think that's a fair statement about you to make. Takes one to know one.

For the casual user, who isn't that up on NO2 theory, who frankly doesn't know wtf is going on (wow, this describes 90% of NO2 users I've met), I posit the ZEX kit is better than your brand of choice. In this case, idiot proof outweighs everything else by a factor of ten.

Am I making any sense here?

 

Even though it's idiot proof, it's still a great kit beyond that. I will be using it for a 100-125 shot before the end of the year. The ZEX kit is still a good kit for a application of up to 125 shot, not something I would recommend to an idiot, so it is a good kit for non-idiot users as well.

Becuase it's made for the streets, not pro . I know your smarteer than that .

 

I think the safest and baddest system would be hondata nitrous control direct port, how many other nitrous systems will pull timing for you and add fuel? RPM windows, MPH windows, engine load options, plug and play. You could run a direct port and add no fuel through the hondata, just jet your mixture right. As far as the safest systems and components in those systems it's pretty easy, no matter how you inject nitrous/fuel there is always some type of switch or solenoid that will release it into your motor, any of which can fail, some may have a higher failure rate but there is always a chance no matter what system you run.

Spray it till it pops mang!

oh sorry, didnt know they sold the zex kit as a street kit and not to be used by professionals for track use

Damn I forgot too .

We seem to swing hammers everywhere these days.

 

fwiw, with a wet kit you don't have to worry about the fuel injectors.


with a wet kit just get a fpss and you are better than zex just my .02. i like the safety and reliability of a wet kit, upgradablity too...
