Just starting to learn about this stuff so I aplogize in advance for my lack of intellect...

I was researching a IC sprayer and afer reading up I am happy I didnt go with this kit...

I am thinking about spraying nitrous...

Can someone explain to me the following..

A bottle warmer what does it do? Do we need them for our cars?

How does nitrous affect a dyno tune? I am getting dyno tuned this spring by AMS and I dont really want to have it just tuned for nitrous... Do you just add the nitrous or do you tune around it or what? :confused:

Do you guys spray it out of the hole? Do you spray it with the button or full throttle?

Anything else I should know??

Thanks in advance!!
 
You have a lot of options with nitrous as to how you use it, but lets first go through the actual parts of the system.

All cars are the same as far as this goes:

A bottle warmer does exactly waht it says. It warms up the bottle, and nitrous, which in turns raises the pressure inside the bottle. This is beneficial to you, because a higher pressure in the system will insure that it works in the manner you want it to.

A purge line is such that there is no air in the line that would cause the car to run rich in between when you start adding extra fuel (assuming a wet system) and when you actually are getting more oxygen into the manifold to need that extra fuel.

a remote bottle opener is just so you don't have to physically open and close the bottle valve everytime you want to use the nitrous.


as for how you apply the nitrous, here are a couple popular options:
If running a large turbo, you can use a small (35 shot) amount to help spool the turbo. this gives you a rediculously long power band, however after first and maybe second gear, doesn't do to much.

If you use it with boost to help control temps and add O2 you would use a small jet setting with this as well, especially if you don't have much of a fuel system yet.

As far as controlling it, i would either use something like DSMlink, which has a seperate nitrous control that is very effective (you set rpm, TPS setting, and it actuates it)

or if you want to be simple, a WOT switch (or button on the dash), that also has a seperate "system" on off switch.
 
Well I have everything ready to go for AMS dyno on the 25th mods are in profile, motor is broke in.... no tune :)

Looking for options...

Sorry to be a bother.


Can someone explain the diffrence between a fogger and direct port...

i know a wet shot is "safer" or so im told.

I would like to spray a small 50 shot... Can I just add the shot after the toon or do they need to tune around the nitrous??
 
A fogger kit has one nozzle, a direct port kit has multiple nozzles and are plummed on the intake manifold. The advantage of a direct port kit is that it mixes nitrous/fuel in each cyl in the engine.

Either way with a turbo, if you get nitrous, you should get a wet kit. If you get a wet kit, I recommend Zex.
• Designed to work safely on stock type engines, but is also engineered to perform flawlessly on highly modified turbocharged and supercharged combinations. The ideal nitrous system for any fuel injected vehicle.

• All major components are factory pre-assembled inside the "Nitrous Management Unit". Easy, plug and play, two-hour installation.

• ZEX Nitrous Systems have an advanced, patented feature called "Active Fuel Control". This feature monitors nitrous bottle pressure and adds or subtracts enrichment fuel so the engine never runs too rich, or too lean, when you engage the nitrous system.

• ZEX "Wet" nitrous systems activate at wide-open throttle using advanced electronics that monitor your engine's throttle position sensor. This makes using your nitrous system very easy and reliable.


I started a thread on her about IC sprayer bars where a shop did tests on 3 different products. http://www.dsmtuners.com/forums/showthread.php?t=206296

These were the results, some people believe it, some people don't.
DEI CRYO2 kit : 12.5HP gain
NX N-ter Cooler kit : 10-12HP gain
NOS Intercooler Spray Bar kit : 18.6HP gain and chunks of ice on the intercooler.

EDIT:
Just checked your profile, on second thought WHY THE HELL DO YOU WANT TO RUN NITROUS ON A FP RED? Just turn the boost up.

If you want faster spool then spray a small shot like 35 as drive music now said. But if the nitrous is for track use, why bother? You'll be launching from a stop at 4500+ RPMs anyways.

I agree totally, and you posted the very same link that I was going to. :)
 
Turbo + Nitrous = more power....

As far as tuning with the nitrous it's not really a big deal if you don't, althogh if you have it installed when you go to AMS I would have them setup the nitrous maps for you while your there.

That's not necassarly true bro.

You have to compensate with tuning for when you spray because the cold intake charge temps will cause your boost to shoot up a few more psi.

I run 20 psi off of spray, and then when I spray it goes to about 22 psi, and 22 psi is all that I can run on turbo alone without timing getting pulled drastically on pump 93, and if your timing is getting pulled drastically on a 2g, your knocking. :)

Perhaps you are going lean on your 550's (quite a strain running 22psi and a 75 shot on injectors only 100cc's bigger than the crappy stockers) and that is why it is pulling timing.

Well... you have to keep in mind that a wet nitrous kit doesn't depend on injectors for it's fuel supply. You tap into the fuel line for it's source of fuel, in which my walbro 255 pumps plenty of fuel for my nitrous kit, and my injectors.

And yes... anything past 22psi would cause timing to be pulled, according to my logs on my logger. That's why I said that 22psi is all that I could run on turbo alone without timing getting pulled.

Anyways... I'm not even running a FP B28 turbo anymore, for I have now went on to a FP Green turbo, so now I'm in a whole different ball game. :)

Then I would guess that the inefficiency of the B16G compressor at 22psi may have been heating the intake charge and causing the issue. The switch solving the problem is an indication of this.

I don't know what I was thinking then about the fuel.

Aaaahh hell.... you were just trying to help with a problem, and that's what it's all about!! :thumb: :thumb:

You have a good looking GSX, you need to modify that thing!! :thumb: :thumb:

I've got something very big in the works, I just have to work out a few more details and get my 60,000 mile service performed. Hopefully by January or February at the latest there will be some very heavy, and unconventional modification going on. That's why I started looking into these threads: I'm very interested in nitrous, water injection and pump gas setups (meaning using all three in conjunction.

Since this thread is all about stupid nitrous questions, I'll go ahead and ask what ET differences certain sized shots will have on typical DSM setups? Say a mid-high 11 second car and a decent sized shot. I ask because the spray isn't constant, so it's affects aren't consistent across the powerband and it has some very interesting side affects (like the boost spike Gen X was mentioning) and charge temperatures. What about using it in conjunction with water injection?
 
I saw a 5 tenths and 7 mph gain from a 75 shot. The sooner I sprayed the better ET got, without much change in mph. Eventually I ended up engaging the nitrous at 25 mph, IIRC, and went 11.52 at 122 with my evo on the stock turbo. Non-nitrous runs have consistently been 12.0 at ~114 mph for over a year.
