Nitrous questions....

[EagleStroker]

My turn to ask for some advice again. Some of you know, some of you don't but eventually I want to tear the car back down, ditch the blower cams, and jack the compression up. That day is no time soon as my funds just won't allow it, but I'm constantly changing things with the end goal in mind. I've never messed with nitrous, never had a need to, but I'm thinking about biting the bullet and trying something new.

My first question is will I need to upgrade my fuel system? On the Mustang Dyno I'm @ 385 to the rear, so I'm not sure how much farther I'll be able to take it without changing something. I'm thinking that I'll surely need bigger injectors, maybe 39 lbs? Will a pump upgrade be necessary? And if so, it would be majorly overkill, but how about a return style system? Any down side to that?

Second, I'm looking at buying a used wet set up, it doesn't have a window/wot switch so I was thinking about upgrading while I had the chance to something like this:

Worth the cost?

Third, assuming I buy that I'll have to bottles to play with. Is it worth the hassle of hooking them both up or should I just install one and swap them out? The problem to me with running both is the added cost, because it means 2 bottle openers, 2 heaters, etc....

I don't want to half ass it, and have been reading quite a bit on the subject but it's time to ask some questions!

If you are using a wet kit you won't need injectors. You will need a gt500 fuel system, or the Fore Precision fuel system or a BAP. Or a stand alone fuel system and not tax your fuel system supplying your engine. Forget about the return style fuel system K.I.S.S. (keep it simple stupid).

For an example of a standalone fuel system on an 05 and a nano system look here: http://www.nitroustech.com/forums/showthread.php?t=154

A window switch is a must. IMO

You can y the two bottles together or you can look in to a NANO system which will allow you to use more of your bottle keeping you at a constant bottle pressure.

Excuse my ignorance, but NANO system? And I agree a window switch is a must, is that controller what I would need or should I be looking in a different direction?

On the stand alone, I think that is a great idea in itself, but that in itself is more expensive than upgrading my existing pumps. That being said, is it a better way to do things? I actually have a battery relocation kit sitting in the garage, could be the push I need to install it!

I have also talked with Fore about that, I could run a line off my rails and bring a 3rd pump online when it comes time for the shot. In that scenario, what are the best pumps to use?

1) depending on how big of a shot you want to spray you'll need to upgrade the fuel system. Not sure about the size of injectors or the return system but you'll definitely want either a ford gt or similar fuel pump to be able to handle the extra fuel, check lethal performance i know they sell some nice ones

2)everything from harrisspeedworks i've heard great things...I don't have any experience with that window switch but it looks more accommodating than my zex window switch

3)i went with a single bottle setup so i could still use my trunk if need be, so IMO go with the single bottle, depending on the shot the bottle lasts quite a while, and it's nice to have another laying around so you can just swap it in real quick without having the temptation to use both bottles at the same time....


i'm a noob at nitrous as well, i literally just started using mine a few days ago, but ive been picking out parts and building my setup for the past couple months, so ive done a lot of homework on the subject

A standalone will allow you to adjust the nitrous fuel pressure better and doesn't depend on your in tank pump which is a plus imo.

 

[matt texass]

a ford gt or similar fuel pump

The mustang has an equivalent to the ford gt one stock.

I plan on starting small and getting used to the "hit" but would like the option of bumping to a 175-200 shot. The kit I'm looking at has the option of a 200.

Space isn't so much of an issue as I have some pretty good ideas as far as mounting goes. If I go with a single I'll gut my shaker 1000 box and stick it in there, if I go with a dual I'll be making something to go under the trunk carpet. Might raise the carpet a few inches but I prefer things out of site out of mind.

Thanks for your help Matt! That's some good information. How much do those Nano systems tend to run? And I to prefer the idea of a stand alone as it doesn't mess with the existing system, it's just pricey. I wonder if it would be more cost effective to put my own kit/fuel cell/pump together?

If you start getting up into the bigger shots (150+) it will be much easier to run a stand-alone fuel system. You are going to need the higher octane regardless, and you don't want the hassle of driving all the old 93 out of the tank to fill up with 104, just for a few hits of the spray. You will want an upgraded fuel system. Injectors, pump, etc. Your factory injectors are more than likely close to being maxed out as it is right now.

Forgive my ignorance again, but if I add a stand alone where does the need for the upgrade come into play? Seems like the extra fuel is coming from the fuel cell...

Your blower cams will work great with nitrous,no need to pull them.

Would blower cams be better for N2O over n/a cams?

 

[silverstang07]

well if you do the stand alone you will have to have an aftermarket pump anyways, so yeah sorry I left that out of my post. A blower cam will work pretty decent for nitrous, the same concept applies. BEST thing to do is have a custom nitrous grind made for you. I'm going to be running the SPR stage 3 n/a cams in mine FYI

 

[EagleStroker]

These were a custom grind but we were working with roush on the now TVS at the time.

On the fuel system though, if I'm running a pump from a fuel cell directly to the nitrous set up, why is there a need to upgrade anything else?
