2.8 with nos?

[ImArider]

i drive a 2.8 and the only power upgrades i hear of is catback exauhst, supercharger, and a couple of other little things. why has no one ever mentioned nos? (except fo that guy who always says "my nos aint nossin right")

[AUD-A4]

hmm,thats a good question!!!has any one ever done a nitrous hookup on their 2.8??

i dont know why nos is always considered rice these days, or affiliated with fast and furious...

nos has been around alot longer than that movie... and is a good power adder when all else fails...

just be smart with it...

[AudiRacerS4]

someone has put NOS in a 2.8 before I remeber seeing the post her on AZ and over on audiforums.com

Nothing wrong with doing it since the 2.8 is NA, but just remember that adding nitrous(GAS) increases the compression while being sprayed. Make sure to do a wet setup which will spray nitrous and fuel at the same time, it will also need to be tuned for the setup since the adv timing will need to be retarded or you need to run a higher octane(but the car will run worse while not spraying the nitrous).

Get a wet kit from zex, nos, nx or from a couple others. Zex will problably be the easiest to install. It comes with almost everything you'll need. Additional stuff would be a bottle heater, nitrous pressure guage and if you really want to, a window switch. If you get stuff from ebay, a good 500 will get you the whole setup. Start out with a 35 shot. You dont need to retart timing with a 35. Work your way up till a 55 shot then think about retarding it 1-2degrees. I think its a nice way to gain some Hp without the expense of supercharging.

[ImArider]

how much horse power gain could i get from a 500 setup approxamitly

[ImArider]

where could i go to find information about a nos setup. cause i know nothing about the timing and all that. plus i dont want my car to run like crap while not using it.

[48855]

Depends on the shot. Every kit is a little different. I've only dealt with zex kits since its such an easy installation. A zex 35 shot will give you 32-33whp at 1100psi(nitrous). 55 shot will give you 51-52whp at 1100psi and so on. I wouldnt go higher then a 55 shot without checking A/F.
Google nitrous. There's tons of information on how it works, difference between wet vs. dry kit, etc.

[ImArider]

what was your experience like? did it effect your car when not using it?

[AB18]

I remember seeing 2.8s running 13s with nos a while back.

[48855]

Well, I im not running nitrous on a 2.8, but im running nitrous on my mustang. The mustangs naturally aspirated just like your 2.8 and same v6 with 3.8 so im thinking its going to be similar.
When I run up to a 55 shot, I leave the stock timing alone( meaning stock ECU with no chip or anything). Car feels "normal" just like a stock car when im not spraying b/c the timing hasnt been touched. Now im currently running a 100 shot and for this, im retarding the timing 3-4 degrees. With the timing retarded, the car feels a little sluggish like its lost like 10-15hp when im not spraying.
But in your case, if your not going to run high shots of nitrous, im sure its fine to leave the timing alone. Just dont chip your car that'll advance timing.

[speedydragon]

can you still turn with 55shot nos on?

[A4Shizzle]

Wait! If you do this, use a second hazard switch in one of the empty spots as the arm button.

[Tiluleshpingen]

thast f-in hilarious ahahahahahahahhahaahahahaah

[AUD-A4]

hmm,this is starting to run thru my mind. as you can see from my sig,i have a giac chip. would this effect a nitrous setup at all? like posted before the timing setup.

[48855]

Im pretty sure GIAC advances timing a bit to make the car responsive and add a little hp to it too. Be sure to call them up and see what they did.
Most kits come with activating/arming switch and throttle sensor switch. You dont want to spray when your not full throttle. Also make sure you start spraying 2.7-2.8rpms+. I wouldnt spray below that. Also, make sure you stop spraying a good 300-400rpms below redline.

[nizmosx]

i wouldnt touch zex or nx with a ten foot pole. there are better kits available.

i would get an edelbrock nitrous kit. If you dont get the edelbrock nitrous kit, make sure you at least get their nozzles. they are by far the best spraying nozzles on the market.

you can visit the site for more info.
http://www.edelbrock.com/sportcompac...ns_fandb.shtml
if you look on that page there is a good picture where you can see the differenece between our competitors nozzle and ours. i will not tell you whoes nozzle it is for the sake of not slandering another product.

by the way i do not make any money or anything but mentioning my employers kit. I just feel you guys should know that there are better alternatives than buying zex, nx, or nos.

We had a racer Randy Walker running on 3 stages of Nitrous oxide Systems run a 6.74 and with our edelbrock kit on only 2 stages of nitrous ran a 6.54 on HIS FIRST RUN....... you can watch that video here

you guys can decide what you want to run.

[mike-2ptzero]

I know I want to run a edelbrock setup but just have to get it put together

[AUD-A4]

^^lol,i agree

[ProOnThaSnow]

(except fo that guy who always says "my nos aint nossin right")

That'd be me. and the quote is because I am making fun of ricers who call it NOS. Its fucking nitrous. N.O.S. is simply a company that simply ruined nitrous recognition for the rest of the world with their cheesy, and fucking retarded stint in Fast and the Furious.

Nitrous on a 2.8 would kick ass - don't really care what anyone thinks. There's a guy on Audiforums.com that has it, but I can't remember who. Do a little search, its not for the faint of heart and/or knowledge. If you don't know anything about it, don't use it... or better yet, do use it, cuz I wanna see pics of a blown up 30 valve.

[nizmosx]

hahaha ^^^ agreed..... nitrous when used properly can be amazing. there is a lot of miss conception of what nitrous can bring to the table. People hear one person talking shit on it and calling it rice so therfore they think its rice too. next thing you know everyone thinks its rice, and there is nothing left to do but add some chicken and vegitables to make it a rice bowl. not sure where im going with this but now im hungry.

[Ewok_Fetus]

I have only heard one person in this thread here, refer to it by its proper name.... Nitrous...

But I do kinda see it as a cheater method... Nothing rice about it... There is no replacement for displacement... Or a turbo!!

Actually 2.


Nitrous = the product name
NOS = A company name


Using a Nitrous kit or just bottle for "looks"= RICE

Nothing about using it for power is "rice".

i guess i just dont see it as cheating. saying that kinda sounds like how people used to tell me i cheated in street fighter when i am just using the moves that were made in the game. Albiet you are correct when you say there is no replacement for displacement.

I dont think he meant "cheating". People call it "cheater" gas because it is a short cut way of getting more hp quickly.

[nizmosx]

ahh i see, thanks for the clarification. Because that would make a turbo technically cheaating. Either way if used properly it would be a great upgrade.

[ImArider]

so i should leave it alone because i dont know much about it? even if i got the window switch? how dnagerous can it be? anyway forget fast and furious, has anyone even seen Ronin with robert deniro?

[ProOnThaSnow]

Ronin kicks ass, one of the best chase scenes ever...

I ran Nitrous on my integra, probably 20 or so bottle through a stock LS engine, put in colder plugs, retarded the timing (maybe a little too much, but I wanted to be safe), ran a 75 shot, only ran Premium (which I hope to god you are doing in your Audi anyway, and sprayed only above 2K rpms, and let off in between shifts.
It Pulled HARD, and I was extremely happy with it. I sold the nitrous before I sold the car, and the LS with 140~K on it didn't blow smoke, or have one single problem... my buddy actually sold that car about a month ago and it still ran perfect (he never ran nitrous on it).

I was thinking about running Nitrous on my Audi, but I would want to go with Direct Port, and it would add up really fast. I can do all the install, and wouldn't have a problem, but I am also trying to budget my 88 civic/gsr-turbo swap build, and the civic is gonna be the car to beat on, cuz Audi engines run a little bit more.

Nizmosx is definately a smart guy when it comes to nitrous, and he'd be one of the few on the board I'd actually listen to about the subject. I know a lot about it, but I'd trust him over myself, lol. After seeing the spray pattern of the edelbrock nozzles, that is all I'd ever use.

Hey Nizmo, what would a direct port set-up for a 30Valve run cost wise through you?

[nizmosx]

^^^ i will get back to you on that. If your planning on doing a direct port setup you will need to think about where your going to plumb it into your intake manifold. Most likely you will need to get the shortest of the nozzles to make sure you have good clearance between the runners and of the hood (depending on how you plumb it),

Here are a couple charts i put together on how the different setups work in case people are not sure.

Here is a dry kit on a honda intake manifold.


Here is a wet kit on a honda intake manifold.


Lastly here is a direct port setup on the same manifold

[mike-2ptzero]

ahh i see, thanks for the clarification. Because that would make a turbo technically cheaating. Either way if used properly it would be a great upgrade.

Well turbo is just basicly just high compression which is done on race NA setups, but as we all know here a turbo setup is in no way "cheap" like nitrous.

[DRA4]

I would love to put a 75 shot in my car, just afraid of that bottle blowing up.

Hey Spilner, please tell me you're fucking joking?

Goddamn that movie! FUCK!

Nitrous gas by itself is non-flammable. It will not blow up unless mixed with fuel. And If youa are going to run Nitrous, the safest way by far is to run WET (nitrous and fuel sprayed simultaneously). I ran dry on my Integra, but if I do decide to do it on the A4, it will be wet and direct port. I am so tempted to do this, so everytime this question is asked, I can say "Yes its possible, I've got it on my car, at an adjusted elevation of 5,000 ft a 75 shot will put you at an XX.XXX 1/4 mile" - and it'd be in a Tip.

The wet kits are usually the ones that "blow" when the nitrous/fuel are sparked in the intake manifold(thru the intake valves) as it burns back thru the intake manifold and IC. Seen this happen plenty of times at the track and it isn't a pretty site.

[ProOnThaSnow]

Ok, I see your point, but where I was going as far as a Wet setup being safer as it would not create the common lean condition that would cause an engine to go. A direct port I feel would be considerably safer than doing the typical intake fed setup:

Seems like there is a lot more room for error and spurratic ignition there.
