Alright, when I get my car paid off, hopefully by Christmas, I'm gonna have a little money to spend on it. What I want to do is get a hypnotic tune with the new SCT programmer with the datalogging ability AND get Nitrous...maybe a 50 shot or less if they make them smaller. Seems like I've seen a few 30 shots with adjustability to 50 and 75. What do you guys think about this? I know the basics about nitrous and I know there is a risk involved if you don't know what you're doing with it. I want honest opninions here, do you guys think nitrous is a good way to go or not? The reason I am posting in the SVT section and not forced induction is I want opinions from SVT owners....nothing against the other foci, but I would rather people with SVTF's post on this matter since if I do this it will be on my daily driver SVTF.
09-12-2005, 03:05 PM
Yeah im thinking about doing nitrous just for fun im interested as well but i'll prolly be doing a 75shot.. i think nitrous is a fine way to go but not for daily use proly once in a while and keeping a close eye on internals to make sure everything is running smoothly. You also have to keep up maintaince i believe such as spark plugs and things like that. A friend of mine has been running alot of nitrous in his car but he does have an integra iono if the reliability factor on the motor is involved in how his car is fine.
09-12-2005, 03:11 PM
I wouldn't be using it much at all. I would like to get a kit that used the TPS for activation and have it set up to kick in at WOT or maybe 3/4 throttle. So I wouldn't be using it daily, it would be going on my SVTF that I drive every day though.
09-12-2005, 04:10 PM
If no please explain why you wouldn't do nitrous.
09-13-2005, 04:54 AM
Sorry, what was Nitrous again?...... dang, sorry couldn't resist! [;)] It's 3:30 over here in louisiana, and I'm quite the delirious ff right now.
I'd say that if you know what you're doing, a NOS install could be quite beneficial and really fun! DO it...
09-13-2005, 10:31 AM
Nobody has any reason for their no votes??? From the poll it doesn't look like many people have an opinion of N20.
09-13-2005, 12:09 PM
I say go for it! If, I end up modding the crap out of this little car like I did my stang then I'm looking into a ZEX or NX kit. My first choice would be a good blower but N2O seems like more fun on a little car like ours. If, you go the nitrous route then make sure you get all the recommended accessories and not just the standard purchase kit. Things will work better if you go the distance......

More than likely due to the fact that those folks that use N2O frequent the Forced Induction Chat.
I'll gladly move this to those forums if you'd like.
09-13-2005, 02:49 PM
Well, I guess you can go ahead and move it since nobody seems to be posting here. I just thought I would get the input of other SVTF owners on using N20 since that's what I have...different results and install requirements between the SVTF and the normal focus I'm assuming. But go ahead and move it and see what the FI regulars think. :)
You can probably blame our 10.2:1 compression ratio for the lack of Nitrous users.
I'll move this, and hopefully you'll get some more feedback.
09-13-2005, 07:31 PM
Like anything, with the proper tuning nitrous can be a beautiful thing. A 50 shot is really a drop in the bucket but tune it and don't spray until you got a good program in there or bye-bye valves.
09-14-2005, 08:29 AM
Darn our high compression engines!!! lol That's the main reason I was posting this in the SVT section, I was wondering how nitrous and high compression would mix. Maybe I should just spend my money elsewhere until I can afford a turbo kit or supercharger kit and some low compression pistons for some big boost. Of course that could be a while, that's why I was wanting nitrous, I could probably afford that by Christmas. Oh well, I'd rather save money and mod it up right than mess something up.

if you do a google search you will find that nitrous and high compression are a good thing. they supposedly mix well together.
09-14-2005, 11:18 AM
Agreed, my NOS next spring will be hitting an 11.5-1 engine.
09-14-2005, 02:18 PM
What do I need to do to make sure it is safe? You have just regained my attention. What setup I had thought about is having is a "dry" setup of maybe 30-60hp shot hooked to the TPS for WOT and getting one of those switches that only turn on in a certain rpm range and only spraying say in the range of 3,000-6500 rpms that way if I get rev happy or just accidentally let it over rev it will cut off before it harms anything.

09-14-2005, 03:24 PM
i have a nx 50 shot wet kit, nver use a dry kit. because if for any reason the MAF can't keep up with the amount of nitrous going in and the ECU doesn't add enough fuel then your engine is gonna go BOOM and that's not gonna be a pretty sight. also things to get are #1. WOT switch #2. RPM window switch. and the rest are just goodies. a nitrous gauge might be good because it'll tell you whether it's ok to use it or not.
09-14-2005, 03:34 PM
Along those lines, use an electronic NOS gauge, not a mechanical one. Last thing you need is to spring a leak of NOS in your cabin.
09-14-2005, 03:45 PM
Ok, change that to a wet setup with the wot sensor and rpm window switch and of course gotta have a purge kit [:D] More than likely would get an SCT Xcalibrator2 from Wayne and get a tune for n2o to go along with it. I'm just assuming this, but you can unhook the bottle at any time and store it somewhere else right? I wouldn't feel safe just running around with a big bottle of n2o in my hatch at all times.
09-14-2005, 05:54 PM
Yes, just yank the bottle out
09-14-2005, 05:56 PM
Thats what I would do. I have a NX kit that I am running a 50 shot and a 75 occasionally. I just use the extreme tune software and have wayne send me a tune for the 50 and 75. Not the best to drive around if ur not using it because it is REALLy fat in between 3500-7200. I have a NX pressure gauge mounted on the bottle, but I kinda want one in the gauge pillar but that is a lot of Stainless line to run up there and the Electronic gauge is over 200 dollars. I have the kit installed inline with a WOT switch and a button. So if i hit the button I HAVE to be at WOT and vice versa. I also have the purge by the way, but yea it is a nice thing to have. ALSO dont forget the buy 2 steps colder plugs. Get the MOTORCRAFT AFZS22C i believe something like that, they are 2 steps colder and can be ordered through your local ford dealer. The Iridiums are expensive, but Wayne had an electrode break off in his old ZX3 and bad things happened. lol, Best luck with the motorcrafts, plus they are a helluva lot cheaper. Lemme know if you have any other questions regarding the NX kit or accesories.
09-14-2005, 06:17 PM
i would go for it just be extreamly careful
09-14-2005, 08:51 PM
What exactly is a purge kit?
09-14-2005, 08:59 PM
A button that activates a system that "purges" the line before you shoot for optimal spray

the motorcraft plugs are 2 step colder, but only compared to the regular ZX3, the svtf's are already 1 step colder, so therefore it's only 1 step colder for the SVTF users.

if you've ever watched fast and the furious than it's whats spray's out of the windshield sprayer nozzels. it's like a big mist that comes out and puts on a show for everyone, and also helps purge the line of any air that is there so you get the full shot of nitrous.

So, how much will the whole setup cost me if I get a zex wet kit or a NX kit. I saw an entry level venom kit on jegs for like $498, it didn't have all of the fancy controls but it did have the sensor where if it was running too lean it would cutoff.

that i'm not to sure about, but it all depends on where you live who you know and what not. i got mine used for cheap and it came with most of the stuff, so i end up only spending $250 on everything. but if you buy retail i'm thinking about $600-800, depending on what goodies you want.
09-19-2005, 11:45 AM
I think nitrous is a good "add-on" But I know from past cars of mine that had it. I got addicted. Is it fun? yes, Is it safe? I think so if done right, would I rather have boost? yes. Does having a Vortech w/ nitrous sound even better? Hell yea, To bad I'm going to sell my kit[?|] Why? I don't think I will use it as much as I thought I was going to and there is only 2 places to get it filled here and from what I can tell neither really has a set price they just charge by how well they know you. Since I do not drive a Honda I get charged more.
09-19-2005, 01:26 PM
Most places charge between 3.50 to 4.50 a pound for nitrous. It is a good idea to check around in your area and see if anyone carries it.. We go through a couple hundred pounds a month in the summer at my shop. We charge 3.50 a pound right now, though it is going to go up to 3.75 next month.
09-29-2005, 09:51 PM
Granted I am not an SVTF owner but I have quite a bit of experience in the nitrous field as my ex-boss has setup spray on about 90% of his vehicles. Hell, we even setup a dry kit on a Golf GTI for a kit that was cleaning cars at the car lot.
You can spray dry without too much concern of making your engine go BOOM. It will however melt the tips of your plugs if your fuel system cant keep up. Bear in mind that going dry means relying on your engine's computer system to figure out that in the 1/100th of a second it takes to fire a cylinder and it to disperse that fuel/air charge out the exhaust valve and down the exhaust system to the O2 sensor, it says "holy samolee, i am running LEAN!!" Then it decides to go closed loop on the regulator valve causing the fuel system pressure to go up and thereby adding more fuel to the cylinder. Hopefully, if it is all in tune, it will add it just enough to get the lean out and make your engine's horsepower go SHOOOOOPPPPP^^^^ right on up. To be on the safe side when setting the system up for dry nitrous, start with NOTHING larger than a .030 pill. Make a pass or two out on some dusty back road and hold on to your ass slimbo, its gonna get fun in a hurry. Remember though, that normal solenoids (little ones) weren't made to go longer than 10-13 seconds continuously before developing what is called "coil scorching". That is where that little coil that activates the plunger gets too hot to handle.
Always make a pass or two after changes and check plugs when engine cools down. If you goto hauling ass down some back road and you suddenly LOSE power, you probably melted the tip off a plug. Do NOT have a freak out attack over this. Unless you melted the whole end of the plug off, you did not do any damage.
I say this from experience of several Mustangs, a 3.8 thunderbird, and a 90 lincoln town car with a 5.0. That one was the most fun because I took that big ol boat from an 11.31 motor only on street tires to a 9.43 with 150 horses of wet nitrous on Hoosier Quick Time DOT's. That big sumbiatch was fast when I hit that go fast button.
If your car is a stick shift, probably is being an svt, rely on a mechanical throttle activation switch and RPM activated switch. BUT!!!! Here is the drawback!!! No matter how you set it up, if you miss a shift and hammer the gas, the revs will build and that nitrous will flow if you floor it and it hits the rpm window switch. The only thing that is completely fool proof to keep you from gassing an unloaded engine is NOTHING. We are human and we make mistakes. I watched a guy nitrous backfire through a holley carb on the line with 200 horsepower of nitrous. He started the car up and purged it again, then sprayed the whole track to the time of 27.49 (19 seconds restarting and 1 second saying every cussword cause he pissed himself).
It is not an idiot proof system, but it is cheap horsepower that is VERY easy to install but a pain to setup perfectly. Once you get it perfect though, DONT TOUCH IT. Just keep bottle pressure in the 850-950 PSI range and you should have happy days when you hit that button.
Be cautious of folks selling theres cheap. Check it out, take it apart and see of screens are broken or gone, seals are shot, or the main shaft is discolored from overheating due to some dork spraying a car for 30 seconds. Best thing to do is a ZEX kit because it ties in with the O2 sensor and monitors the system, not just sprays the motor. That is what I want to do with my little ZX3.
Happy ricer hunting and some of those little punks that think that since they have HONDA on their car it means I CAN FLY FASTER THAN YOU hunting.
09-29-2005, 10:01 PM
Forgot to mention this too, Nitrous kits new are usually a lot higher than used. Contradiction in terms I know, but if you find a used system on Ebay or here for about half the cost of a new one, grab it and make sure you find out if the system has a non doa clause to get your money back if the person/dummy before you burnt the system up.
Be cautious, but remember, nitrous is fun and definitely NOT for daily driver use. Quick note also, best place for the half full bottle of nitrous in the summer time is the refrigerator. Keeps nitrous dense and bottle pressure WAY down. If you get a shop near you to fill it, chill the bottle before heading up there and wrap it in a blanket to keep the cold in. It will make filling it MUCH easier and quicker.
Good luck with your decision. hope I have given some helpful advice.
09-30-2005, 04:28 AM
First off, nitrous likes high compression engines. I can't tell you how many tanks of nitrous I have ran through mine. I usually run a 50 shot but have switched to 75 a few times. Just run high octane gas, colder plugs and a small spark plug gap .035 or so. And don't go WOT before 3000-3500 RPMs. And stay away from the rev limiter. Do this and you can run a 50 shot forever. I am on the stock tune as well. I intend to get a tune but haven't have te extra cash since moving to Texas last month. My compression is perfect as well. I check it every few months. I have had no problems with my car other than a bad clutch and valve cover gasket. PM me for more information or email me at
09-30-2005, 11:26 PM
There is a guy here in Northeast Arkansas that told me he would do dyno pulls and burn a chip for $300. Regardless of how many pulls he makes to get peak horsepower. He also said anything you wanna setup before bringing it to him, he could burn a chip for as long as its Ford, for the moment.
If you want his number gimme a shout at firstname.lastname@example.org and I will shoot it to you.
He also said if you make mods and want him to reflash chip, it would be around $150.
03-19-2006, 01:06 AM
he's got an SVT, requires a reflash, no 'chips'
But, I'm running an NX kit with the big solenoids, a compucar purge, NOS remote opener, 50 shot pills in the Shark nozzle, an MSD digital RPM window switch, fuel line tap from CFM, of course a WOT switch.
Currently I run with the stock tune, I have an xcal2, but I don't want to run a nitrous tune, since when the nitrous isn't on, the timing retard would make the car run like crap.
I am in the middle of setting up a Crane ignition system with a retard controller that will pull the timing only while the nitrous solenoids are activated. That way I can run my aftermarket tune with the better timing curve, and it pulls the timing back out once the spray activates.
So far I've run 1 10lb through it, no problems. I am running the denso iridium plugs right now, but have the Motorcraft azf-s22c's sitting right here waiting to go in.
03-19-2006, 07:26 PM

The nitrous is like crack...one or two hits and yer hooked.. it is a nice boost though.. i've learned to use it ONLY if a car starts inching away..then its curtains for the other car (hopefully). I put an azz woopin on a SRT-4 (tuned) about 3 weeks ago... very nice.

08-28-2006, 08:03 PM
In response to Heavy E's comments about the dry kit, I recommend to get wet. I've sprayed wet and dry kits and the dry kits will not put out the power as our ecu's cannot compensate for the extra amount of oxygen since we have no fuel return line. If you're going to spray dry you'll need a tune, which means you'll run extremely rich until you spray.
Edelbrock sells a dry kit. I've told them that this will not work very well, if at all, on returnless fuel systems. They sent me a dyno where they had setup a dry kit to spray through the MAF. The dyno sheet showed gains, however I asked a few questions which were never answered by their support people, even after sending the email 3 times. First question was, "Colder MAF temperatures advance ignition timing. Are you recommending to advance ignition timing while using nitrous?". The second one was, "Did you have any kind of aftermarket tuning done to the car and, if so, what was it?". Third was, "How will the Focus ecu adjust the fuel if it has no return line?". If they are unable or won't answer such questions I would not buy the kit. I'm all for Edelbrock parts, but not answering or being able to answer such basic questions is showing irresponsibility.
Viney wrote up a lot of nitrous information that helped me out in my trials for my zx3. If you're going to get nitrous, do it right. Get a wet kit and have lots of fun. Keep your A/F ratios fairly reasonable and you'll keep your engine happy.
On the other hand, your clutch will hate you [burnout].
10-28-2007, 10:03 PM
I love the NOS. I have used it for a long time and like any forced indution if used and tuned properly it works fine. In my case I have been using a wet kit for the fuel control, DIS 2 to control timming and lets go baby! Plus it keeps me from running my car hard all the time as I used to when it was turbocharged.

11-26-2007, 11:50 PM
^^^^Make sure you have a good tune spraying an SVT, they really need some timing pulled out for the nitrous. The like to eat valves.
11-27-2007, 11:05 PM
I have the DIS 2 pulling the timming at around 3500-6800 RPM's. The nitrous does not come on till 3500 via window switch and WOT Switch. So far it has been working fine for me on a 75 shot.
11-28-2007, 03:59 PM
Ok ok..Im not to fancy on car lingo, but my dads a pretty good Ford guy with engines..so from what Ive read get a Wet kit, with a WOT switch (not sure what that is) and an RPM window Switch as well, as well as a tune (before or after the install)?
11-29-2007, 12:52 AM

I dream 50-75 shot of nitrous and my PowerWorks S/C working really well together. Then I realize I need to build my bottom end and wake up.
09-17-2008, 10:43 AM
Things you should know about nitrous:
Run colder spark plugs
Run 93 octane fuel
Run a WET kit that also sprays extra fuel
Higher than a 50 shot may require an ignition retard while spraying.
If you use a TPS switch, set it to FULL throttle only.( why would you not, you dont need to spray unless youre going all the way?)
A wideband O2 sensor isnt a bad idea either, about 150 more bucks but cheap insurance.
09-17-2008, 06:37 PM
What do you mean by a wideband O2 sensor? U mean a wideband A/F gauge?
