Well, it's taken a while but I've finally got it going! I had problems with an EBay seller that jerked me around and my low priority install (had more important things to fix, like broken axle :) .. However, I did the first 'Test burn' last night!

Now, before someone replies with 'Nitrous is not for rock crawlers', let me say:

:flipoff2: - It's my toy, and I'll play with how I want!!! :D

I've always wanted to play with NOx but didn't dare screw with my daily.

So, how about some pics!
Here's the kit I bought off Ebay. I had originally won bid on a Nitrous Express kit. That fell thru after a couple weeks. However, I had already purchased jets for the NX system. When I got the NOS system in, I was able to modify the NOS fogger to use the NX jets…. One problem solved. ;)

Here are a couple install pics....

Notice, I did an Ignition upgrade before installing. The factory coil is mucho weak! MSD blaster II, much better.. :D

And another view...

No shit!!!!! That's cool as hell! The question is dose it work good and if so I want to see video if it in action!!!! :flipoff2:

Now for first impressions… :)

It's been cold and rainy here, and that play havoc on the Nitrous bottle. It needs to be 70 degrees to work properly. So, I used a hair drier to warm the bottle before going out for a test run. I got it up to 750 psi, still cool but hopefully good enough for a first try. First shot was with a 24 NOx jet and 14 fuel jet. That should be good for around 25 HP. I hooked up the EGT gauge to monitor header temp.

Foot dragging on the brake to hold 50mph, 4000 rpm in 4th gear. Hit the button, there is a definite tone change to the motor. EGT is still climbing, so I shut down after a few seconds and go back for jet change. I put in the 18 fuel jet and try again. Hit the button and off we go! After about 2 seconds, the motor start to lay down. EGT is DROPPING.. Ok, I'm way rich. That's a good start. I go back and put in the 16 jet. Now I can give it a real try…..

Hit the button in 1st gear! Oh shit, 6 grand FAST. No spinning tires, but hell they are 33's…. Hit second gear, and it come on HARD! Actually too hard. When I shift, the lines are full of NOx gas, and it fills the intake runner. When I come back on, it's FULL of NOx and goes LEAN…. I think the solution for this is an RPM switch. Shut the NOx off at about 5500rpm, then once you feel the power bleed off, shift and dump it back on!

By the time I made several runs, the bottle was cooled back down below 700 psi. I could tell it was not as effective. I should be running 900 to 1200 psi, so I'm sure I'm not getting a full HIT…. It may not be 20 HP right now, but it sure is THERE! :D

They are calling for 70 degree weather by this weekend! I should get a real test then.

We are headed to Joplin this weekend. There is an awesome gravel hill that I fought with last time.... Good time to do a real test!!!:D :D

And people call me crazy :eek: Cool that your trying something different. Could be a fun way to surprise people at the stoplights :D

any bet's on how long the cast piston's in the motor last :D

I talked with Jayson last night, and he wants us to take the trucks out to Midnight drags at the local track....

I don't know if I'm ready for that yet.. :)

It would be cool to see a bunch of trucks on huge swampers try to make some 1/4mi runs.... :D

I think 1/2 the fun is seeing their face when they see that big ol'e blue bottle sitting the the back.

I've already had a request to hook up a mask for the passenger seat! Maybe I would not be so hard on passengers if they had 'something' to relax them.. ;) :D :D

Man, you just ain't right in the head! :D
Might be kewel for some mud drags, tho

You had better be on the lookout for a Swift GT bottom end... :nuke:

Oooh, that would be cool! Then I could turn it up....

How about a 130HP 1.6! :D :D

Just remember the NOS gets you the same O2 and fuel per second - it gets divvied up between however many intake strokes per second you are currently using. The same 25 hp shot that is fine at 4000 rpm hits the pistons twice as hard at 2000. Just a thought. I like the idea of it. Keep us informed. When ya' gettin' a turbo? :flipoff2: :D

Yes, very important to remember. The ideal setup is to use a window switch, that will only enable the NOx between an RPM range (such as 3K to 6K). Otherwise, you HAVE to remember to get off the juce if the motor starts to lug, or it will :nuke:

For now I'm just gonna watch the tach. If I really like the juce, I'll spend the money for the switch... (in the mean time I'm watching for any bargins on EBay.. ;) )....

Nice! youll have to write up a detailed post of how you installed that, is that a 8v? 1.6? or a 1.3?


As long as you sit on a 25 shot over 3-6K you shouldnt burn anything up, but eventually youll get hot on the sauce and blow something, happens all the time :-)

My lil daily driver 16v would love for nothing more than to get one of those kits :-P I know Id roast my lil 235's at the line :-)

So ya think this is the anwser to making it up waterfall ??????
Just back up and peel out:smokin: :smokin: :D

CJ

Are you runnin a dedicated fuel system as well ?

marcutah - I'm running a 1.6 8V motor. It's got a conservitive 1.3 EFI cam and the compression has been bumped (.020 off head). Built for torque...

Titanium - The NOS is feed from the adjustable fuel pressure regulator you can see in the pic (blue top). I'm running a boost pump (inline) and the stock EFI in-tank. I've got LOTS of flow, and about 70 psi of pressure! That's the reason for the very small .016" fuel jet.. :)

TablerockToy - Na, the waterfall is a finess climb.... The BIG waterfall would require the NOS!! :D :D (snorkle or scuba gear only required if you don't make it ;) )....

Kool, i like the NOS and been thinkin bout it myself, u beat me to it :mad: :flipoff2: Looks like u got ur shit together, a vid would be really kool, ya know.............

I have often toyed with the thought.
I have a 150 hp NOS kit in my dad's basement.
It's a bolt on plate to fit under a Holley 4 barrel carb,
(hard to apply to my Zuk).

Can't tell from the pics.

Where is your raw fuel dumping into?
What's your fuel line pressure?
What type of seal do you have on your air cleaner/intake assembly?
Do you have an arming switch and a switch on the linkage (WFO switch) or a toggle? How are you switching it.

The last time I studied NO2 it was for big V-8's.
Low compression, sewer pipe intakes and exhausts, large cam.
Forged bottom end.

Does that still apply?

We tried a WFO switch on the linkage, It only works when it's WFO.
Bad result, excessive tire spin so you let off, hit WFO again and it's up in smoke. Definately needed a progressive setup for the street.

This is a simple single nozzle setup. It injects in the intake before the throttle body so it MUST have a WOT (or WFO as you call it :) ) swith. For this, I robbed a good heavy duity clutch switch from a parts Sami and mounted it on the peddle assembly inside the cab. This keeps it safe from dirt and water over the engine.

The Nozzle uses two drop in jets to control fuel and NOx flow. That sets the 'size' of the shot. 20 to 25 hp is about min, and you can go up to 150 hp (not on a 1.6L though).. They cost about $5-6 each.

If you have a NOx setup, all you need to do is buy a nozzle and the two SS lines from the solenoids to the nozzle. Everything else is generic. I've found several great online calculators which will tell what size jets to use (or at least get you in the ball park).

I would not reccomend the so called 'dry' setups. They bump your fuel pressure to provide the extra fuel for the NOx. From what I've experienced, the stock EFI pump is not good for the extra pressure and flow. Wet injection is the only safe way to go, in my book...

For big HP gains you need forged pistons, retarded ignition, top rate fuel etc.... However, the general rule is to stay below 40% gain and off the rev limiter and a stock motor will be unharmed. Most motors get destroyed when people get greedy ;). It's just SO easy to change a jet for a bigger boost.. :D :D

Oh yea, the nozzle fit right into a boss that was already on the air duct! It's for the AC high idle, and I moved it forward to the old crankcase vent port. No drilling require... :)

I email Nos dierct 2 years ago and had them bulid me a fogger sytem for mine 4 nozzles 1 for each cylinder drilled and taped into the intake your setup looks alot eayser i was there for a month bidding all those steel lines LOL!!!

try yout bottle at 1400psi seen a @#$ do that on 97 350vortec blew that plastic intake throught the hood .

Nos is like hand guns . Nos doesnt kill your motor its the person operating it.

i still like the must common 1 O NOS are you crazy it will catch fire LOL!!!!!!!!!!!

I spoke with the local "Blower Rebuilder" in my area last year about NOS. I also spent an hour or so on the phone with NOS. Everyone who knew thier stuff loved the idea. Those who knew nothing scowled at the idea. Properly done would be a good deal but ppl think im gonna run my samurai down the 1320 and stand on the NOS for 22 out of 26 seconds......... not the intention. Not the way to use it, obviously. Would really help in thick goo to help turn those big meats. Any idea if forged pistons are available ? Im thinkin 2 second bursts of NOS will keep the rpm up in the goo, will last a while usin it this way.... :eek:

When I was reasearching this project, I did find some info on the Toy board on putting NOx on the 22R. One comment I saw was the problem of even distribution to all the cylinder on that motor. I'm guessing it's caused by the shape of the intake manifold, but I never got any replies to my questions. With 4 nozzles you would eliminate that problem, but I have yet to tell if the Sami intake is going to do that.

Again, keep the hit small, and I don't think it'll be an issue.

I think an RPM window switch is necessary to use the system safely. I'm will get a chance to test the system out this weekend on some chat piles ;). If it's too much to do and watch, I'll raise the RPM switch in priority.. :) From what I read, most motors are destroyed by either going into rev limiter or dropping the RPM too low! Either one can be terminal with NOx..... :nuke:

yep you can get forged pistons for 500$ can even get titauim rods

Dont know if titanium rods are necessary, theyre tough as nails as is.

The verdict is in,,,, I LOVE IT ! :D :D

We went wheelin at Joplin this weekend. They have some chat piles left over from some mining in the area. One real long pull, I fought hard last time, I had my sights set on. This time it went like this...

I lined up at the bottom, turned on the bottle. The gauge read 800 psi. It was about 75 degrees, so that's probably about right, and good enough for some fun. :) I was in Low range and started in 3rd gear. I hit the bottom of the hill at 5500 rpm, within about 6' the motor pulled down to 4500, that's when I hit the button ;)........ The motor quickly ramped back up to 5000 and STAYED! It was probably about a 10 second pull to the top, and the motor never dropped below 5000! (as we say in Okie land) "Just shittin and getting", chunking rocks all the way to the top. :p

The guys watching, said they could hear when I hit the happy gas. The motor tone changed, and it sounded awesome!

I heard one of the locals get on the radio... 'hey, the white Samurai just made it up the rock pile...... On the RIGHT side'...

GAWD, I love it... :D :D :D

Sounds like just the right application of "just a little bit more"...good job.:D

is this thing still running with that wet kit in it??

that single fogger wet kit is a hand grenade waiting to happen. it dosen't distribute the fuel evenly between the cylinders. the fuel will sometimes puddle in the intake and cause a back fire, especially if you are low in the rpm's. i understand why you went with the single fogger. it is the only way to get anything less than a 50 shot. i would've gone with a dry kit and jetted it to a 50 shot and richened it up a little bit. after that you would be looking at around 40hp and it would be alot easier on your motor. wet kits are violent, and with an aluminum block and cast pistons you are asking for trouble. i would really be scared with any kind of bottle pressure. you should also get an air fuel guage and see exactly where you are sitting at all your different rpm's. egt is a little scary for tunning nitrous.


i'm not bagging on your ride!!! i love nitrous but really would like to know how things are going the way you have it. give me the 411!!! take it easy.

A while back on the edelbrock website. I ran along a NOS product. THey called it progressive nitrous. It had sensors to your throttle and adjusted itself accordingly from 0- whatever as you accelerated. It was mentioned as a good way to go for four-wheelers.

Anyone heard of this. I checked the site the other day and couldn't find it. This interests me more than waiting till I need it and hitting it hard. This way I could wait till I approached something I needed Umph for and turn it on and let it do all the work.

THoughts?

you can read more about it on the holley website. holley bought NOS a while back. it is called a progressive nitrous controller. they also make a digital one now.

Sweet thanks! So what do people think about it though. Cool or ghetto?

it's definately cool. but it's up to you if it's right for your application.

the way to go for me a couple years ago was not only nos, but also propane! of course this was on a NA diesel. the rig was totaled not to long after being built, the next step to cool it off was going to be methanol! lol.. dont you love horsepower junkies :flipoff2:

propane works bad ass on diesels!!!!:D
