This is where I ended up placing the arming switch for my nitrous kit:

Here is the bottle in the trunk.

The sensation of the added acceleration is bizarre... at first I felt like there was another (faster) car, pushing mine from behind! Or a giant invisible hand pushing the car forward faster! It is really a strange sensation, but I love it! Lots of wheelspin... great excuse to get bigger tires!

Looks great. I like the arming switch there Nice and discret (sp?) have fun with it

 

dude that looks great..i also like where you placed the arming switch...maybe i'm gonna get zex

CL'S

 

i miss my cl :/

 

Welcome to the CL-N2O Club!

I like where you mounted the arming switch.

Congrats on the install, and have fun!

 

very nice install!!
BTW i gotta question for u guys with autos that spray. When u race and u arm the switch and hit full throttle the nitrous is engaged i know that. Usually u would hit a button( like the NOS kits) when u reach a good rpm like 4000 and let off when u shift. But with the ZeX kit its activated at full throttle. So do you guys keep the pedal down even when the car is redlining at 6200rpm shifting into next gear? or does the ZEX "smart" system cuts the NO2 off when the car is shifting? The point is that i think is very bad for the tranny if it shifts while NO2 is spraying. How can u control it to not to spray when the tranny is shifting? I think spraying an auto is harder and more risky than a standard with a conventional NO2 kit like NOS. Let me know wassup. I think im going to invest in a zex kit as well.

 

from what F0de told me, in a 5spd, you have to let off the gas when you shift. If you don't pretty much, when you get into gear again, your intake will explode your air filter. I could be wrong though.

 

Soo..is NOS better for the 2.2's or 3.0's?

 

Whats the worst that can happen with NOS in a 3.0?

 

I was under the impression that it is equally risky for both. That is not saying that it is accident prone, but that there is an equal danger with either cars. Ask Dustbuster4 he has a 3.0 with Nitrous

 

Well i mean its not on my list of things to buy.. . .but i was just courious

 

Congrats welcome to the zex club .

 

NX..

 

Yea u dont want to keep spraying whjen u shift which is my question. In a 5spd u stop spaying when u shift but in the auto when ur at WOT the ZEX sprays. How do u control for it Not to spary when ur tranny is shifting.If ur letting up on the gas than the tranny will upshift. I figure u would want to keep flooring it. So how do u guys do it? Or do u NOT need to control it. Do u just put the pedal to the metal and let ZEX do its thing??? I figure it will be a lot of load on ur tranny when it shifting into next gear while ur spraying. Anyone understand what im trying to ask?

 

i thought most Nitrous kits were "throttle" controlled, with the switch being under the accelerator, depending on the pressure it would spray it??

 

In my auto I just spray the whole race, even while shifting. Its really no big deal at all. I've had my kit for over a year and was probably one of the first people to have a zex kit on this board and I've never had a problem doing it this way.

 

Sorry but you thought wrong. The zex kit is controlled by slpicing the zex control unit to your tps sensor. The zex unit then learns the voltage for WOT and from then on it will spray (when activated and the bottle is open) and WOT. It has nothing to do with your accelerator or the pressure being applied on it.

 

Rick please explain the NOS use on a 3.0 and what you have to do in order to make it work correctly? hows the shifting work and how would you stop it from blowing the intake from "overdoing it"? i want a zex kit but i want to do my research first. i was also looking into a nx kit. lets take a vote ZEX, NX or NOS? and which is better for which application 2.2, 2.3, and 3.0?

 

The zex kit doesn't use a microswitch... it monitors the voltage of your throttle position sensor (TPS) so when you are at full throttle (with the switch armed) it will inject the nitrous.

With an automatic, I guess you could let off the gas by about an 1/8 inch and that would cut out the nitrous, but still be almost full power during the shift, then after the shift foot back in the floor. Probably the safest way to go easy on an automatic transmission.

The injector is supposed to be like 8" to 12" ahead of the throttle body (I don't have the instructions in front of me). And, remember to use the ZEX plugs and to check them to make sure you aren't running lean. Oh, and use 92 or better octane gas. And finally, if using more than +55 hp shot, you must retard your timing. I'm going to use an MSD 6 Plus Digital ignition to automatically retard the timing when I go to +75 hp "squirt".

Someone said "it feels wierd", I agree 100%! It doesn't seem right that your car is moving so much faster, for so little cash and so little work! It's great!

Anyone in Milwaukee: I sell the N2O gas cheaper than anyone around.

Here's the secret to running Zex in the 3.0CL:

Turn bottle on.

Flip "on" the arming switch.

Mash the accellerator to the floor, until desired point (in time or distance) has been met.

The end! :P

Seriously, you can run at WOT without worry of detonation. The Zex unit will manage your fuel and N2O engagement. No need to let off of the accellerator between shifts.

I have not let off of the accellerator at any point during my 20-25 runs at the track this year.

 

thanks for the replys DB4 and thomasio

 

do you spray in 1st gear? i don't know if i could get much traction spraying in 1st.

 

It's all wheelspin in first gear... but it's great for grins!

 

I want N2O so bad , but I know my tranny will go!

 

i've told a lot of ppl about the downfalls of Zex on this board.. but it seems it just keeps coming back for me.. when the zex control unit overheats from excessive use.. it just opens up and sprays.. i've seen it happen to multiple cars.. and engines were destroyed.. nitrous express is more of a manual system.. theres a switch on the throttle cable.. at WOT it uses the BEST solenoids on the market to spray fuel and nitrous.. throught the markets BEST nitrous/fuel nozzle.. which equally mixes both together and then sprays it into your Intake or intake manifold.. NOS is a close second to NX.. but on closer observation of the NOS kit.. the solenoids are a lot smaller.. and break a lot more often.. and most NOS kits are dry setups.. where ALL of NX kits are wet kits.. Nitrous is forced induction.. its bad for your motor. and if you need your car to drive to work or school every day.. i wouldn't consider using it.. i personally had a 75 shot on my cl.. went through a 12.5lb composite bottle a day.. which put me back at the shop refilling bottles every two days.. for about a year straight.. the f22a on my 5 speed cl held it very well.. i ran non platnium spark plugs.. as platnium and nitrous don't mix too well.. and rarely changed my oil.. if you know how to use nitrous.. you'll never have any problems.. but if you don't know exactly what your doing to your car.. and exactly how it works.. you'll end up blowing up your motor.. 6 cylinder or 4 cylinder..
