It's a Zex wet shot sytem, with optional pressre gauge and purge kit and bluue purge light. The bottle is mounted in a custom fiberglass box in the trunk and the purge comes out the driver side fender vent. It's a diffenitly noticable when it sprays and it's only a 55 shot. I will have more detailed pics tomorrow sence it's raining here. Plus I'll have video and some track times by saturday.

more, I'll post more tomorrow

looks pretty sweet:)

thats awsome but out of curiosity what gear would you be in when you spray it
and do you think the sealls will take the preasure

How does it ride?

and do you think the sealls will take the preasure

Charles Hill's does with no problem.

Oh wow I like it

Very Impressive. Congrats on the installation! Eager to hear the results of your track times.

it rides great! I sprayed getting on an on ramp and hit 90mph before I got to the end of it and that's about an 1/8th of a mile. The purge is even as cool as the ride. the switches are mounted in my ashtray, put it in 1st andnever have to take your hand of the shifter!

First we saw nitrous from charles, then turbo from Jeff & Jon, now more nitrous...
I wonder who's gonna try them both first:)

The whole package looks great...

Don't tempt me like that!!!

Very Impressive. Congrats on the installation! Eager to hear the results of your track times.
I'm eager to hear yours as well, I had planned on getting the Greddy kit, but then a great oppurtunity for a FC buildup came along so I bought a different turbo, Turbonetics T70! :cool:

Nothing quite like a bit of gas........

Turbo then nitros sounds fun!

Don't tempt me like that!!!

:D Why not? :D

I'm a total n00b when it comes to nitro, but how long does one spray last? Is it configurable?

W/ this setup the spray is trigured by WOT, so as long as your at WOT, yes the shot sizes can be changed bigger shot more HP

can we see interior pictures im always interested in switches.iunno why,nice setup

I noticedyou have the K&N intake installed. Wont you getbetter performance w/the stock intake?

sorry, dump question, WOT means 'wide open throttle' am I right?
...but isn't it better to have a button to push? I don't know much, mostly what I've seen from movies, like 2f2f...

Yup Yup, you are correct.


...but isn't it better to have a button to push? I don't know much, mostly what I've seen from movies, like 2f2f...
That's what I would think as well, but to each his own. If it works better for him to activate when WOT, then he should use it. Either way, it's still nitrous ;)

from what I have read you trigger at WOT as the engine managment isn't using the o2 sensors to correct the mixture so the mixture you set with the wet NO2 system stays constant.

the WOT is better NOS newbies because it keeps you from spraying at the wrong time and damaging your engine, plus one less thing to worry about.

Yes that is correct.

have anyone try using the Nitrous Express RPM window switch or Maximizer with the ZEX system ?

Sorry no times, w/ spray. Trying to get my all motor runs constant ran around 9.8(1/8th mile) and on my 5th run, hit three quaters of the way down the track, shifted into third and the radiator gave out and just threw it's guts up. Antifreeze everywhere! called Tripple A put it on a flatbed and carried it home, got it jacked up and will try to get it fixed tomorrow so will have to wait for times with the nitrous till next weekened.

I still thinkyou should compare the performance w/the stock intake

it's a pain in the ass to put back on and then refab the nitrous kit and make the stock filter work with the kit. But, Charles R. Hill has the setup with the stock intake.

So you have a constant spray when you floor it?
How often would you have to refill the bottle? (i drive pretty hard, pretty generic question, but i just want to get a feel for often ppl normaly refill their bottles.)

Is there more stress on the engine / drive chain to use nos instead of turbo? since you increase the hp instanly?

..

..

The spray is constant while at WOT. I have been spraying and purgeing since mid week and I have gone from 700 to 500 psi. It's a hard question to answer, they both put more stress on the engine, I guess it would depend on what shot size you use (ie. 55, 75, 100, 150, 300).

Thanks for the good explanation Charles. So, from what I gather the reason why people go with sc / turbo instead of NOS is mainly due to operational costs? It seems to me that they do exactly the same; slam more air into your engine.

It seems to me that NOS might stress the internals more since the increase in
HPS is not linear but immediate. But the stress is probably close to that with a
turbo which suddenly slams 5+ psi more air into your engine, or does the turbo
add air with less PSI when you are under lower RPM?

If the NOS only comes on at WOT it sounds kinda dangerous, if you are going through a curve and suddenly you have 55+ more HPS at the wheels. From what I gather turbo / sc keeps on slamming air into the engine even when you are not under WOT, so it seems to be a more friendly for the "end user" who does track and not just straight line racing. Pleace arrest me if I'm wrong.

What I have trouble understanding is how the ECU can work this out properly. From what I have read the ECU uses static maps when it is under WOT, and it
does not read data from the o2 sensor. So how in the world can we tune properly? Is it just "to be on the safe side, let's go way rich" type of tuning or?

*ponder*

...I installed a Blitz SUS steel mesh air filter with a custom fabbed/rigged reducer to use in my R.E. system and the engine runs great...
...a local idiot with a 440 h.p. 350Z almost crashed the car...

Charles do you have a picture of this intake of yours? I'm curious to see it...
And when you say 'almost crashed' you mean he totalled the car?
Thanks

I completely agree with Charles, you should learn to drive the car and "be at one with the car" before you try adding things like Nitrous/ Turbo/ Supercharger. And keep in mind all these things do require extra matience and upkeep, not so much with the nitrous, but FI requires lots of upkeep. As Charles siad this system is idiot proof, it doesn't take long to install. My install took much longer due to the extras and the fiberglass bottle holder. But basicly run the lines from the trunk threw the drainage plug, there are factory hooks under the car where the fuel lines run and there is an extra one which is great to hang the nitrous lines. Mount the box, switches, wire them up, tap the fuel line, put the nozzle in your intake, tap on to the Throttle positioning sensor, and select the correct fuel and Nitrous jets for the amount of power you wish to run. And that's it "Your Spraying". The process becomes more complex once you go above the 55 shot since timing has to be adjusted and you might want to look into some different spark plugs. I'll get some better pictures as soon as may car gets back from the dealership, looked at it and as far I can tell the radiator seperated, so rather than tearing into everything and braking it and since my RX-7 still doesn't have an engine in it I just flatbedded it to the dealership, this way I will have my means of transportation back a hole lot quicker.

I’m going to sign up for driving academy at Nashville Speedways (it is normally a nascar oval, but they have a track course in the center of the oval) in late February to learn more about my car, myself and how to drive properly. Depending on how well / bad that goes I will decide weather or not my car needs any upgrades.

NOS / FI is far down on the list though. My first upgrade is going to be new tires and possibly rims. Then sway bars and new flywheel. Then new springs and lower the car a tad. If the car still behaves nicely I will consider nos / fi.

Point of order - FI requires NO special upkeep; just change the oil as you would normally, and don't treat the car like you hate it. Now, the car DOES require the operator to monitor things; but as far as maintenance goes, its little different than before.

Also, I doubt ANYONE here has had their car long enough to 'be one with the car' - what we have is a few owners who are simply 'good drivers'. Good drivers can drive well in any car. If this forum follows trends, i'd say 5% of the membership is a 'good' driver. 15% are 'accomplished', 60% are 'average', 15% are 'below average', with the remaining 5% being 'poor' drivers.

Sometimes even poor drivers have enough will and money to add power to their cars. And frankly, adding 50hp to the car won't make it into an Enzo-killer. A mid-high 13 second car is quick, no doubt, but especially with N2O, that power is more-often applied ONLY during straight-line acceleration. Thru the twisties, the power, especially N2O, likely won't be the difference-maker.

:D

everyone listen to charles and dmp.
Remember this is a car that is home on a road track. That is the enviroment it was engineered for--hence the almost mid engine mount, the dual gastanks mid car, the awesome stock brakes etc,etc. Yes you can make a straight line redlight to redlight car out of it(charles can make anything!) but you cannot take the road track out of this car. Therefore horsepower alone does not necessarly make this car faster for its designed purpose. Nos has its advantages,FI has it's advantages,porting has it's advantages. For one I would not recommend any major horsepower upgrades until you put in some track time and see where you with your individual driving style needs the improvement.
The list of mods are now growing after we have been waiting for over a year and the individually of the cars are going to become more and more apparent.as it should be.

Yes, but some times owners can't even do that, and I would hate to see an someone purchase a turbo a ruin it, plus there are other things like a turbo timer, if you don't have a turbo timer pulling up and cutting the car off can damage a turbo, there are a lot of mistakes you can make that will kill a turbo, there are very few that will kill the ACTUAL Zex system. Plus it is no easy plug and play job for an unexperienced mechanic.
Also, I doubt ANYONE here has had their car long enough to 'be one with the car' -
It was just an exression, hence the quotation marks and also, I don't think it takes many people over a year to figure there car out and "become on with the car". I race formula ones and it doesn't take but a few races for me to become adjusted to a new car/ setup.

I realize that someone who has the money can go out and buy the kit with out any preperation it was just a piece of advice. And yes 55 extra HP isn't a great differnce but is one none the less and if you use it wrong you can damage your engine. Yes as others have stated Nitrous isn't popular in road course racing, but in DRAG Racing which is also a popular form of racing it is, why is it everyone thinks that Drag racing is so bad, and everyone thinks that if a car is built for, or handles right in one aspect it can't be changed for another. I have seen Dodge Caravans go out on Drag Strips, where they weren't designed for from the factory OHOH :eek: , and walk down other cars, it's all about what YOU want it to do, build it right and it will do it. Has anyone seen the 20b powered RX-8 in the NHRA which happens to be doing pretty well.

I am interested to see how a RX-8 with Nitrous and FI will do, sence I am interested in doing it as well.

I have the nitrous express intercooler spray kit, and greddy turbo kit on the way. It will be at at Archer Racing all of march getting installed, tuned, dyno'd and whatever it takes to run flawlessly. I'll let you know how it goes. I have the type rs bov, pro fec b boost controller, and having archer replace my apex seals, and i'm going to have two boost settings, 8 psi, and 12 psi.

Are you using MazdaManiac's avatar?

heh, I thought it was Jeff posting for a second there...

how much was the whole setup??

I get everything for cost, being I work through Pro Motion Distributing. I got the greddy turbo kit, type rs bov, greddy turbo timer, pro fec b boost controller, egt and boost gauge, and nitrous express intercooler spray kit with a 10 lb. bottle all for 4,167 dollars

how much was the whole setup??

The ZEX kit was, $600 since they had to custom cut the lines since they don't actually make a kit for the RX-8. After Purge kit, blue Purge light and Bottle pressure guage it was another $200.

I had to also fab my own fuel line, which took about 20 minutes. Other than that it was strictly a bolt-on affair.
Why did you have to fab. a new fuel line?Im going to order this kit soon and was wondering if I will have to do that.Also do I have to get a purge kit or does it work fine without?I know I will get a tank gauge but Im thinking that is all I will need extra.
Thanks,Shark

I did the same fuel line mod, it just makes it easier to tap into. The purge just clears Nitrous and condensation from the lines. I would suggest it, so you don't get water in your engine. Earlier when I said the lines had to be custom cut I meant ZEX cut them to length at the factory. They don't give you much extra.

Sounds good,I will try to add the purge to my order.Thx

Sounds good,I will try to add the purge to my order.Thx
I think you will like it, it's a fun little show. Everyone was betting I would waste my first bottle on purgeing. I got the blue purge light, so my purge cloud actualy lights up blue. :cool:

I would like to see a picture of that :):):)

I'll try to grab some more photos tonight. Some time next week I will get to a dyno and see what I am laying down.

My guess is that Horse will see about 240 rwhp with the nitrous on the dyno. Let's see how close I get.

CRH
I guess we will find out next week! :D

watching with interest

This is kinda along the lines of what I've been thinking about doing... :D

I skipped all the extras like a purge kit. I have my own way of doing that, anyway. I purge when I open the tank and release the pressure when I close it. Works like a charm and no extra parts are needed. The factory rubber-covered vinyl line needs to be replaced with some EFI line from a parts store like NAPA. About three feet should do it. I got four incase I messed up somewhere. Cut the factory line off of the red "quick-connectors" using care not to damage the factory O-rings and replace with the EFI line. Install the T-fitting from the Zex kit properly so as to feed the fuel solenoid. Voila! The fuel supply is done.


My guess is that Horse will see about 240 rwhp with the nitrous on the dyno. Let's see how close I get.

CRH
So are you replacing the lines with EFI lines to keep condensation down in the lines or?
Could you explian more on how you purge the lines again?I would rather save the money and get something else like a cold air intake on the same order and install it all at one time.
Shark

Well, I have to admit it is fun to show. But your method for purgeing is basicly spraying the Vapor and air in the lines intothe engine so actually you are doing the same thing if you didn't do your "purge". I suggest the purge kit to properly keep water vapor from entering the engine, after long time abuse this can damage your engine. As I said before Nitrous is only bad for the engine if you use it improperly.

http://www.zex.com/Information/Products/PurgeLight/PurgeLight_002.wmv

vid of the purge light. high coolness factor.

Very high coolness factor, I still suggest you get the purge kit but that is just my opinion.

First we saw nitrous from charles, then turbo from Jeff & Jon, now more nitrous...
I wonder who's gonna try them both first:)

The whole package looks great...
I'm getting the porting first, then turbo and tuning next, and last ill get the nitrous. ALL I NEED IS THE CAR!!!!!!!!!!!!! :mad: :mad: :mad: .

I must admit, I might change my mind at some point on the purge issue. I am also wrestling with whether or not I should re-circulate my BOV because I just don't like to advertise the h.p. lurking under the hood. Those Mustang and Camaro guys are easily beaten when things are nice and quiet, and I could use the cash to offset the expense of this car.

CRH

Well, I still suggest using the purge kit, I talked it over with some people last night and they told me what you are doing is a BAD idea, and also that the water injection analogy makes no since because in that case it is not being sprayed into the engine through the throttle body with trash. Just purge before you get to the line, then when you are coming down the return lane when no one is watching.

So how much power did this nitrous kit produce?

I don't see how this method of purging is a bad idea. A purge is a purge pure and simple. If you close the tank and do a quick run with the nitrous on to empty the line, it's just like running out in the middle of a race. So you run rich for a second. Big deal. I don't see how filling it back up when you go out is bad either. You need some form of purge. There's more than one way to do it. You don't necessarily need a purge valve. My friend's Z-28 has a 150 shot with no purge valve. When he starts the car up and wants to do some runs he blips the throttle a couple of times to make sure the line is full. No harm done and it works. No telltale fog for others to bitch about. That's cheatin' ya know! ;) When people purge, they usually hold it too long to show off anyways. That's paid for horsepower getting shot out in a white mist of waste. It only takes a fraction of a second to clear out. When pressure is that high, gas travels very fast.

Well, looks like I may be the first to run Nitrous and a Turbo. I have a Greddy Turbocharger on the way and should hopefully be on by Friday.

I'm not sure, I don't have alot of experience with computer tunning, I'm learning though I have a Haltech unit on the way for my RX-7 dragracer, I'm excited about both. I just love being able to plug right in and tune the engine. I'll probally get my sponsers to setup the map as a base map and then we can tune it from there just like we are doing with the RX-7. Well, the turbo won't be on by Friday, the deal my sponsers offered me has changed and it is actually worse than I can get it retail, so I have to do a little work with them. But either way I will have it on within the next three weeks. I'm leaving town for an event on Friday and if by Monday we haven't come to an agreement I will order it from someone else.

sure, your help is always welcome.

Is it easy to switch between the two maps, ie a button, or do you have to plug up your laptop to switch?

With the GReddy Profec E-01 you point and click and the maps are switched.

CRH

Hey CRH, will the Profec work with the CZ units?

CZ plus E-01 = CZ Stage 3

Kev...It won't work with the gold E-manage units though :(

Thanks Dan - looks like I will NOT upgrade to Gold E-Manage after all, because I wanted to use the E-01 myself one day with Nitrous like Horse and Charles have done.

Hey Horse, you mentioned that you have the purge installed, any pics of it?

sorry no pics at this time currently the system is out of order, I over tightened the AN fitting and busted it so I have to get it cut off and a new one crimped on. What's the differnece between the Gold Emanage and the blue one? I have already got my E-01 and my type RS BOV this afternoon I am ordering my Greddy Turbo Kit. So I suspect since the said they have 3 in stock that I will get it about next Friday, and will be finished with install by about that Wednesday, if nothing goes wrong.

I am not sure if I ever mentioned but I did get a few runs in before the car broke and then the Nitrous lines broke. While Spraying my 1/8th mile times dropped a full second.

Any news, Charles? I ordered my turbo saturday so it shouldn't be long before it gets here. I doubt that I will continue to spray on a turbocharged engine, but who knows.
