To keep it simple n2o is liquid turbo/supercharging. Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight) wich is more oxygen then the air we breathe. During combustion n2o breaks down and releases oxygen. This extra oxygen will increase the power output of the engine just like craming more air in with a turbo or supercharger by allowing you to burn more fuel as long as you can supply it The nitrogen is a bonus and helps keep the combustion chamber pressures under control. Nitrous also has a intercooling effect by reducing intake temps. I have seen it reduce my charge air temps by as much as 80 degrees but you must becareful because some fuels will return to droplets and cling to the wall when cooled to much and screw with your air fuel ratios.

I have found that when tuning 2 degress retard for every 50shot of nos will get you in the ball park and as long as you can maintain fuel presure the wet system will enrich the mixture enough but always start with a step up on the fuel pill.

Hope this helps,

Thanks D..

So if am wanting to spray Nitrous, What do i need to do?
Where I get started??

Thanks.

BTW: check your pm

 

hehe newbe question all N20 does is add more oxygen to ur fuel mixture but doesnt that mean that you would lean out and possibly blow ur motor. which also means u should be looking at new ecu and lots of cash. i dont kknow i think id just go for the new ecu and for a little more a bigger intercooler, force air n the fun way

 

Not only does it add more Oxygen..
It greatly reduces intake temperatures.

See my MOD list in SIG..

I just want some tips, and where/what to do
to spray some Nitrous...

YES I know the debate: Get real power, Turn up boost,
get this and that port job and etc.. At this time.
I basically got all the Bolts on.. SO be it I can
maybe upgrade some of my MODS.. BUT other than
getting a rebuild with PORTING, and either upgrading
my turbos or go single.
I am basically as far as I can go.. ( I plan on getting TUNE asap on current set up).

Some of you may wonder. WHY?? go the nitrous route.
IF you ever go to the TRACK 1/4.. Youll realize,
that EVERYONE else is SPRAYING, From Supras,
RX7's to Civics.. PERIOD.. YES even RX7's spraying
Won't say who but i am sure many do...

So if you have 2 equal drivers 2 equal cars with same mods, THE ONE with NITROUS is gonna WIN..
And to be competititve to even think about reaching
9s 10s even 11's.. Nitrous is the edge to beat/win
competitions..

 

I'm going to butt in and say, why go drag when RX7s were made with handling in mind.... anyway...

Peter's blue XS FD uses nos also. Think he's in the mid 10s or high 10s.

if you are still on the stock twins, I think you should just invest the money on a single turbo, then go from there.

The only time I don't mind nitrous is when it isnt the only thing that makes the car fast.

 

Tips? Put the nitrous bottle and some gauges under the passanger seat like in the fast and the furious.. And then just lift up the bottom of your seat right before the race..

If you want nitrous then go ahead but I personally would say get at least a street port first..

Ernie knows alot about it because I think he was considering running non-seq with a 50 shot(I think) to get him down into the low 11's.

True nitrous is cheaper but it's not power that you can consume all the time(or I wouldn't suggest it) and you still have the price at around $4.00 a pound to refill the bottle everytime you run out. X's that by a 10lb bottle and you have about $40.00 a pop everytime you run out.

Pulling the motor and having it streetported is much more expensive especially without a hookup or paying someone else to do it but IMO it's more worth it then spending 1k on a nitrous setup..

 

anyone , on the forum that have actually use
nitrous??? Any advice?? Can Nitrous be used
with stock injectors??? anyone??

for all those that opposes using nitrous..
I understand where you are coming from.
I used to be a Nitrous NON Believer also.

Unless you guys are strictly bracket racers,
or don't even go to the track, and just
speed on public roads.. NOS is not for you.

But if you race, and want to be competitive.
and DSM's, Civics, 300GT's, Supras and everyone
else is running 11's 10's some even 9's and all
SPRAYing.. Then what other choice does one have?

Racing these days without Nitrous, is like going to a
GUN fight with a KNIFE..

Eventually I do plan on geting a rebuild with BIG Port job
run non sequential, and even go SINGLE TURBO and etc.
BUT EVEN with ALL THAT.. with out NITROUS. You are DONE, can't win..

Nitrous maybe a cheap way to faster times and etc.
BUT i am to the point i have no other choice..
My motor is OK, doensn't need rebuild.. and SINGLE
turbo Cost toooooo Much at this time..

If you guys don't wan tto respond, can you guys
give me a LINK to some FD3S with nitrous???

Thanks

 

Yes nitrous only add oxygen, you need to supply more fuel or you engine will pop. Nitrous come 2 ways wet or dry.

Dry system only insert n20 and use the stock fuel system to add fuel. Can be okay for small power increases, but I don't recommend it.

Wet systems supply n20 and fuel proportionally. Usually you just put a t in the fuel line and run it over to the fuel n20 solenoid. This is a much better way of doing it, less chance of popping your motor.

One advantage of n20 is you can spray it off the line to give your car power while the turbo is spooling up. If you have a large turbo it may not reach full boost till 5K, nitrous can give you power right way. It also cools the intake air making more power.

N20 gets a bad rep similar to the way the rx7 did, idiots not knowing what they are going.

 

I think that most are using it to spool large turbos, and are only spraying a small abouts. I think that spraying on the stock turbo will qiuckly shorten the life of your turbos, by causing them to over spin.

 

You are going about it all wrong, if you want power, upgrade your turbo's and get a street port to keep up with the 9 second civics you are racing.
RX-7's run 9, 10, and 11 second runs everyday with out the use of Nitrous.
If you think you can run it off the stock fuel system you are kidding yourself.

May I suggest two big scuba tanks full and a 250 shot???

 

NOS

 

Yes, yes... to Glassman you listen.

You say you can't afford a big single turbo yet.... well, then wait. You are gonna cost yourself more $$$ with n20, something tells me.

Think how much cooler and more proud of your car you will be making a 10 sec FD with a 13b, withOUT N20. Ported motor, single turbo, slicks, loosen up ur springs a little to nose raise up at launch and make it sit back and take off better. It's all in 60' times. Get ur 60' times down to just over a sec. Mastering the launch with an FD is huge...

 

Thanks MKoch and Forcefed7.

Finally somebody with real input.

So basicallly you just get a bottle of N02.
and pipe it to T it to the Fuel line.

So do you try to maintain the a/f ratio of
11.3:1?? under no2 shot?

Under turbo boost. How does the N20 effect the turbos.
So if the turbos are maxed at 12psi, would the no2 shot make the boost creep and hit your boost cut??

BTW: Other than the major tuners like Pettite, PFS, KDR, SR motorsport and etc.. Who has a 9 or even
10 sec FD3S, single turbo or twin with out NO2??
Something I would have to see to believe.

 

You must not be in the drag scene too much. There are alot of 10sec RX7's without Nos. Hell, I'll show next week Abel runs 7's without it and Ray runs 7's without it. Its not needed as much as you think it is, especially if ya run 40lbs of boost.....

 

Charlie I need 2 bottles of NAAWWWWWWWWWWSSSSS the big ones, and i need em by tonight.

 

alright, that's it. I'm confiscating all of yalls FnF DVDs immediately. ;-)

 

Here's a link to a 7 using a nitrous system. I believe Rob is/use to be a rather resected guy here?

Look here for info on a 75 shot install.

http://www.rx7turboturbo.com/robrob...ous_install.htm

Looks like it works rather good, the Zex system is a "smart" system so it regulates the fuel pressure for you. I'm going to look in it probally.

later Gun

 

I got an idea. You can hide the cannisters beneath the passenger seat! And hide your stage 2 in the AC button!

 

You need to buy the nozzles and selniods(use the jets to adjust the amount of fuel and n2o for the amount to hp you would like to have) Now there are alot of diffrent types of nozzles, do a search about them. The ones I have both the n2o and fuel shooting out it the tip. Tap the inlet elbow and place the nozzles somewhere out of the way. I would use hard line (like brake line or copper)to pipe the n20 and fuel. Tap into the fuel system inside the engine bay and wire the selnoids to a switch. thats the short of it


I plan to do all this after I get my tranny fixed

 

But what about the hazard button???

 

Well, there you said it - Nitrous (let's get off the NOS stuff) is like Steroids (without you stating the obvious explicitly), I've always thought the same thing.

Unnatural, a cheat, a temporary fix, a cop out. At least in my book. I don't think turbos are quite the same. Nitrous is a quick fix, like a shot of heroin - hell they even use the word shot . Turbos are a permanent apparatus.

I can't even get myself to go single so maybe I'm an odd man out, but nitrous for me is for Civics and the like that need it. I prefer to associate my car with the NSX and Vipers of the world. I must be getting too old....

 

Nitrous might be cheaper now, but later you will be rebuilding because of the nitrous. Just save your money and get a bigger turbo. When it is time to rebuild, get a street port done or maybe a brige port with that new turbine for you 10's.

 

You should also remember that a properly set up nitrous system is not going to be cheap. There are other things besides a basic kit that you really need to do it right. Bottle heater, purge valve, and a pressure gauge. A remote bottle opener is not needed but nice to have. And as already stated, you need to make sure you have plenty of fuel... You end up spending quite a bit of money by the time you are done plus you have to refill. I only would consider it after I have done everything else.
I tried to take a short cut with nitrous once and it cost me a motor and a tow home from the track. I may eventually go back and do it right but only after I am done with everything else and exhausted all other ways to get more power.
