Some suggestions about nitrous please

[gyger]

Ok well I've been thinking about getting a nitrous set-up for
awhile. And I think I'm ready. I own a 2000 MTX returnless style Cougar
and I was wondering what would be the best kit for me. Besides the
Venom VCN-1000 or the VCN-2000 in which I can not afford. I don't want to
push my motor to the brink of destruction but I would like to have maybe 50
more extra horses. I already did a SEARCH (http://www.fastcougar.com/forums/searchresults.cfm?requesttimeout=500)
and I noticed the majority of people that are on our forum that have nitrous set-ups
also have return style cougars. Mindtrip and Gary do not but they also spent
close to 1500.00 on their set-ups which I can not afford.
From what I've seen it doesn't matter but, I have 19lb injectors, Calibrated Pro-Flow MAF
and of course SVT parts and I/H/E. I think I'll have to buy 2 stage cold plugs or something like NGK's
and maybe run higher octane gas. Not sure. Any kit advice would be great.

Thanks
Mike

You could get the basic NX kit for around $500. You wouldn't need all the extras that I purchased since you would only like to use a 50 shot. With you having a MTX I would still recommend a window switch no matter how light of a shot you use.

What made my kit so expensive is the digital progressive controller. It tolled in an additional $500 on its own.

With the basic NX kit can I still raise the shot from like 50-60 or 75?
What's a window switch?
And with the NX kit would it be a dry kit?

[mindtrip1016]

I believe that all NX kits are wet. The size shot is all variable by the size jet that is used. A jet is simply a peice of brass with a tiny hole in it which fuel or nitrous is forced through. The larger the hole the larger the shot.

A window switch is wired to the ECU's tach signal. It tells the nitrous system what rpm to start spraying and what rpm to stop. This is used so that you do not over rev the engine while spraying. We all know that there is a fuel cut off point and when nitrous is used with out added fuel, kaboom!!!

Ok after some more searching what I have gathered is that I can NOT use a
dry kit. So I have to Buy a wet kit. Which will tap into my fuel system and then
I'll tap into the side of my Intake tube with a nitrous line. Is the wet kit safe for my
car? I always heard dry kit was the safe way to go. But like I said I don't know much
about nitrous yet. Also I already have my Fuel pressure gauge line running to my shrader
valve. Will it be ok to run some type of splitter fitting on the shrader valve so I can hook up
two things to it? Wow I have a ton of questions

thanks
Mike

I have never seen a shrader valve splitter. You could always run a T fitting into your fuel line if needed.

I believe the big fuss about wet kits not being safe was because of fuel puddling in the uim. Of course the people that were saying that did not have a nitrous system in their vehicle. So they wouldn't know. The NX shark nozzle atomizes the nitrous/fuel mix and at the same time the engine is sucking in all the air that it can at WOT. There is a mist and a hard sucking engine, how is fuel going to puddle? In theory, I believe that it could puddle, but no one is going to run that large of a shot on a Duratec. If they did run that large of shot, they would be using a direct port system, which bypasses the UIM all together.

Ok So I am going to have to find a way to run both my fuel pressure gauge
and the line from the NX solenoid off my fuel line. And don't worry I've read
all the discussions on wet kits pooling and I know it won't. Especially not with
a 50 shot. Has anyone on here ran a mechanical fuel pressure gauge with a
wet nitrous kit???
So a wet kit takes fuel from the fuel line/shrader valve and mixes it with nitrous in the
nitrous solenoid and then sprays it into the intake through a jet????
Is this correct? I thought it just sprayed nitrous into the intake.

Puddling can be a possibility, but honestly on a low shot not sprayed for days in a row, I highly doubt you'll have a problem. Pull the UIM a few weeks after use and check it.

The NX kit comes with jets from 35-150hp...on a V6, it'll be 35-75hp. With a 35 shot that'll be more that good for you.

The basic kit isn't too expensive, and honestly I'd add a bottle heater at min, otherwise you'll feel like the bottle is empty at like 35-50% full.

Window switches are also a good idea as said, to start the Nitrous spray at WOT from 3000rpm to 6250, and it'll cut it before the redline in case you hit it.

NX kits range from like $550 -$750 (depending where you search).

With a 35 shot that'll be more that good for you.
what do you mean? you think it'll be to much strain on my motor?

Has anyone on here ran a mechanical fuel pressure gauge with a
wet nitrous kit???

Yes and no. It gets the fuel from the fuel line or shrader valve, then goes to the fuel solenoid. There are two solenoids, fuel and nitrous. There can also be a third if you choose to purge. The fuel and nitrous run in separate stainless steel lines to a two port nozzle. Between the nozzle and the ss lines are where the jets reside. Within the nozzle is where the nitrous and fuel are mixed together and sprayed into the intake 4"-6" from the tb.

I think I am going to take some pictures for you so you can get a better idea of what is being said. A picture is worth a thousand words, right?

Ok this is the info I got from Summit Racing.
$559.95 for a NX (Nitrous Express) kit Includes solenoid and lines and jets ranging from 35-150 shot
comes ready to go at 100 shot I think he said it came with a window switch and a bottle (obviously)
It's labeled as an All Ford EFI Nitrous kit and I'm pretty sure he said it was a wet kit.
I told him I need a wet kit and my car was returnless with no FPR.
Part # 20922-10

[mindtrip1016]

I am surprised to read that the kit comes with an rpm switch. Mine sure didn't. Does that price include shipping?
I added a couple of pics. One of a jet and the other of the nozzle. I would post pics of the solenoids, but the n2o is behind the coil pack and the fuel is behind the master cylinder, so I have no way to even see them with out removing the uim.

[gyger]

Well I was surprised to hear that it came with a window switch too. So I called
NX and their tech told me that it did NOT come with a window switch.
But it's Part # 189595
Bottle Warmr # 15939

Does that price include shipping?
No shipping, I live like a couple miles from Summit Racing, I live in Summit County:biggrin:
That's why I'm always broke.
Thanks for the pictures now I understand how a wet kit works.
My wife and Parents don't want me to get a Nitrous set-up, cause last year at Compact Nationals
some dude was sitting in line (in his car) waiting to get in the gates behind my parents like 4 cars
and something happend with his Nitrous kit and his hood blew open and came off and smashed his windshield.
I heard it and I was over a 1/4 mile away, sounded like a shot gun blast. I still don't understand
what he could've done to have that happen. But the guy that works at Norwalk and that was clearing people
out told my Dad it was a nitrous problem. I know this sounds like some BS but I believe my parents and they
saw his hood and busted up car.

[mindtrip1016]

I have heard of things like that happening also. The culprit is usually having the bottle heater on, but having the bottle closed. With the bottle closed, the bottle pressure sensor can not detect the pressure and does not know when to turn the heater off.

When I was at Mopar I found a Universal NOS Kit that has all your basics; bottle, lines, switches, etc and it was for 400.

Sorry to chime in so late, but after reading everything posted, I was wondering about the "window switch"...Is this something you buy directly from NX or another source? What is the approximate cost?
Thanks!
