Nitrous questions for my 99 Cobra

[eillob]

Sorry I missed your question about gap. Are you running an MSD or high out put ignition? If not it would probably be a good idea to get one. With nitrous you have to close the gap on your plugs a bit because the theory is that the nitrous has a tendency to snuff out the spark on a plug with too big a gap. A high output ignition will give your plugs a little more ass. Now you still have to close up the gap on the plug but with a high out put ignition you won't have close it up as much. For example stock gap should be around .054 with no ignition upgrade you plug setting with nitrous should be around .038 with an msd ignition it should be around .044

sweet.. am i able to retard the timing with the distributer or do i need a reflash or chip?what do u guys use?

[eillob]

My advice is to yank the chip if your running one. Chips advance the timming, you don't want that. Just retard the timming a bit at the distributer. If your running a 50 or 75 shot 2 degrees should be plenty.

I don't know about reflashing the chip Im a little unfamiliar about that, most shops I talked to told me to remove any kind of performace chips I had before putting on nitrous.

Plugs I would run a one step colder plug an go with the 75hp shot. Then increment till you hit 125hp shot. Keep checking your plugs after to see if there is a need to go 2-steps colder often there is not. Also check the plugs right after using the shot. Like ideally you need to run a 1/4 mile slow down pull over and yank the plugs, not even drive to the pits. A pain in the ass I know but this is what your suppose to do.

I believe the general rule of thumb is 2 degrees retard for every 50HP shot. Since your 4.6 is DIS you have no distributor. You need to get a timing adjuster from steeda etc.., to change your timing. But most nitrous manufacturers know this and usually you can run a 125hp shot on a 4.6 w/o adjusting timing. Also if your running a chip definetly pull it out or get a Diablo chip with multiple settings and have one setting for nitrous.

NOS makes a kit for the Mustang 4.6. It's direct injection and doesn't need the manifold to be machined. It has caps that go over all the injectors and spray N2O and fuel into the chambers. This looks to be the best kit right now and this will give you the best tuning options. The kit of course is not cheap but if I was going to use N20 on a 4.6 I'd save up for that kit.

Congradulations on mentioning the system I talked about on page 1 and look I was even nice enough to include the price.

lol

Waka Waka Waka!

[flex339]

oops...but at least I added to the information given about the kit. I mentioned how the kit works with the caps and lack of machining to the manifold and my personal opinion so at least the post wasn't a complete waste of space like this post BTW the NOZZLE system is 100-300 horsepower.

Way to redeem yourself.... you didn't have to I was just giving you a tough timeLoL. Bottom line with Nozzle system although it is the best I just don't see it being that viable unless your just a nitrous lover!

$1200 plus all the other things I mentioned plus I would still get a bigger fuel pump and you definetly need one for more than 150hp shot. Add it all up and your well near $2000 then think $40 per bottle refill. A S/C for a 4.6 is starting to look more and more interesting at high $3000 price tag and it's there all the time!!!. Also for 150HP+ shot levels I'd feel safer with the traditional fogger set-up as opposed to the Nozzle which is a cheaper kit just a more involved install.

Okay, let me first start off by saying that I am completely against nitrous. I think it is a cheap way to get horsepower without truly putting any work into your car. Now that I have said that let's move on. In an earlier thread someone said that a wet shot is much more dangerous than the dry shot...not true. A wet shot mixes the nitrous directly with the gas and causes for ignition directly in the cylinders. A dry shot on the other hand injects the nitrous with the air before it reaches the cylinders, this makes for a lot more room for detonation. People can run wet shots...reasonable amounts...for a long time on an engine but a dry shot is said to destroy an engine in an average of 4 shots. Don't go for the nitrous but if you do decide you would rather go for cheap power instead of muscle than do a wet shot. A full throttle system, being that it releases nitrous into the mixture only when armed and at full throttle, is the best option in my opinion. Just remember you are driving American Muscle not a little import, use your muscle not steroids...

First off if your against nitrous thats your business and your choice. But for the sake of those who are considering nitrous I have to say that you really have no idea what the hell your talking about. Anyone that thinks its safe to inject raw fuel into the intake plenum with nitrous is completely out of there mind.

Please explain to all of us how nitrous by itself is a detonation hazard in the intake plenum when there is no fuel present. Do you really know what nitrous is? Well is sounds like you dont. Nitrous releases oxygen into the combustion chamber at the right time to increase cylinder pressure which intern makes horsepower. Anyone who thinks nitrous alone will cause detination again has no idea what there talking about because nitrous by itself with no fuel will not burn. A wet shot "unless piped in at the injectors themselves" presents a risk of puddling when injected into the plenum. I said it once I'll say it again the intake plenum was not designed to have fuel in it. So when you put a wet jet into your intake plenum fuel can collect and cause you to blow the plenum right off your car without you even using the nitorus at the time. All it takes is a back fire or heat, and guess what mix that with gas you sprayed in there any bye bye motor. Know if that sounds safe to you, have at it . But let me know where your running so I can come watch the fireworks.

Now is you are afraid of nitrous don't use it.

If you don't know how to use nitrous, read up on it before you use it cause it ain't for everybody.

But if you are against nitrous please don't come preach to us on how to use it.

[GTStang]

Good post that guy obviously has no clue what he is talking about.

[daveshapellSVT]

hey v6 mustang.. thanks for your superior thoughts on nitrous.. You just said what two other ppl have been talking about for about a week now lol " cheap power instead of muscle" power is power.. why don't you tell someone that is running 11's with a 100 shot that they are cheap lol i preffer cheap 11's!
