NOS haters, help me understand.

[xjon]

You're right goldollar- the quality is what counts to alot of us. That is what I really wanted to hear from these 240 guys. We really want quality in our cars which is why I spend time looking for info regarding upgrades for my ride. I would bet most of us want the best for our cars in the "long run" not just my car put out 400hp once.

But I bet if you get to the level of Aries, there is a substantial amount of computing and calculation as to what size jets to use with how much fuel per hour. Or else, what happens? Same thing as a turbo or supercharged engine- detonation or destruction of some kind.

[xjon]

I understand goldollar- you put N20 in a car, you take it to the track or dyno and post your result on the thread. You build the engine in your garage and it looks good just on the engine stand. Drink a beer to that. Ofcourse it helps when your work gets proven on the track also:) Thats a twelver with the guys.

[goldollar]

well put xjon, i was just sayin what i tought, cause there isnt really isnt to many people not backing up their reason for not liking nitrious, but done right N2O is a good power source. And i agree that Aries car is pimp as hell, and there is problly alot of hours of planning and calculating invalved in his car.

[xjon]

thanks everyone.

Once again, no offense. Just trying to keep an open mind.

Unfortunately, I'm still on the "intake/exhaust" category with only 72 posts.

goodnight!

[Mr1der]

this thread is making me want to go get a 75 shot...

anyone mention that nitrous can also be used as a stabilizer to help prevent detanation? it's a good thing for boosted cars, so long as it's not a big shot, like 200...

[JESTER]

Now what funn is anything smaller than a 200 shot???

[Nismo_Freak]

Nitrous has no benefit other than straightline performance, it has no throttle control, it's purely on/off power unless you go about rigging a progressive setup on about 10 different settings.

You also can't use nitrous oxide on road courses... compressed gases aren't allowed in the vehicle for safety reasons. It also allows teams to quickly cheat by upgrading pill sizes. Whereas a restrictor plate limits the amount of air that enters the engine on restricted classes for any FI or N/a cars.

Nitrous as a whole seems like a band-aid fix for a lack of power. It works fine in drag racing because you're going straight for a short time span. Apart from that it's fairly worthless IMO. It still can't replace the on demand power of a turbocharger or supercharger.

[The Riot Hero]

i simply dont like the idea that my horsepower can run out.

[Aries]

any of you doubters...I will gladly put a sprayed KA car up against any of your SR or turbo cars in the straits or the twisties if you'd like proof that nitrous can do more than go in a straight line.

But, Alan is correct, sanctioned racing events other than drag racing do not allow the use of nitrous.

[xjon]

Seems like the arguement is now that you can't use nitrous on tracks due to corners and rules. Well I guess there is a negative on N20. But the turbo and superchargers have their imperfections also. Lag and drag.

Band-aid fix for lack of power- seems like any bolt-on would be considered a band-aid fix. My car has 155hp. go to a shop and say "I want to increase my hp, what can I apply on my engine?" Isn't that why we bolt things on to our car is due to its lack of performance or power.

"on demand power"-seems like that applies to N20 more than turbo does. Turbo will spool-up no matter what. N20, according to your set-up requires a button to be pushed or the throttle to be pegged.

[Onizuka]

Lag and drag.

Not true, the preception that FI cars can't make low end or have to wait for the turbo to spool is as absurd as hating on nitrous for no reason. If you want i can show you a torque curve on a SR20 dyno sheet that would make any NA V8 owner cry.

Just like using nitrous, lots of research, using the proper equiment and tuning goes along way.

[D-UNIT]

There are kits out there that progressively adds nitrous the more you depress the throttle. not just on and off. You could have 25% nitrous injection at 1/4 throttle and 80% at full throttle. highly suitable for road course usage. Like my kit.

[xjon]

d-unit - I believe that is what Nismo-freak was saying about the "progressive set-up"

J-spec tuner- What you have is a well matched system, the "proper equipment" as you say. You're low-end power would be the same if you would unbolt your turbo and run your engine as a NA. It is your mid/high-end that the turbo helps, correct?(ofcourse that depends on your equipment size) So to say one has 100% turbo power from the get-go would be false. Due to lag.

[PriMaTe]

I don’t like it for the following reason(s):

Let’s say for example my car, a 240sx, has a ka24de (slow pos stock), intake and headers and a big coffee can muffler. No let’s say I want to go up against an all stock sr20det. My 240sx will need about 150 shot of nitrous to beat it. Now let’s say I win and I kill the sr with the aid of nitrous. Sure I beat it, but I was only that fast for that short amount of time. I am not always that fast. I can only beat the sr20det w/ a 150 shot of nitrous otherwise ill get burned.Another reason I don’t like it is because it’s the easy/kiddies path to more hp. Id like to tune the car to xxx hp rather than take the easy way and just have xx hp for a short race. Another reason I don’t like it is because ppl are trying to use it in touge racing. seriously these ppl are dumb asses Oo I just remembered a rice quote about that!!!

Thats kinda like complaining that another car beat you because it has more cylinders and/or displacement. A win is a win on or off the bottle.

Im not saying from 100rpm (even though almost all commercial trucks are turbo deisels and pull like crazy from any rpm), but most people seem to have it in there heads that turbos dont spool till 5000+ rpms. The fact is, you can have 4000 full boost RPM's with a turbo motor all the time without "lag and drag" as you put it. Its just as "instant-on" as nitrous at the track.

I dont have any problems with nitrous, but a well crafted turbo system is better in every single way except for price (in my opinion)

Even if you did get a nitrous bottle on your car for road racing with a progressive setup, you would run out before the first lap because you spend so much time on the throttle.

[sideshow]

alot of import draggers use it to get their massive turbos on boost, i know the venom team does.

turbo kits are also a lil more flexible in the fact that when u want to upgrade u can put on a new turbo or manifold, or wastegate and whatnot depending on if your engine can take it.

[Turb0wned]

nothing is wrong with nos its gonna have u running some good times for cheap... i would get it the only thing i hate about it is tha some people have slow *** cars and there only fast when they spray other than that there completly stock

[BoyWonder]

Well, I don't hate it, I'm just afraid that if I install it the chances of my car blowing up in a huge inferno of green fire after being ventilated by an automatic weapon increase dramatically..

Jokes aside, I'm all for it. Some of us enjoy speed, but also enjoy very limited spending budgets. If having to resort to cost-effective upgrades is cheating, then I suppose having money to fund more extreme upgrades is as well..

[xjon]

jspec- you still can't say it's instant-on. Yes 100% boost at 4k but to get to 4k is another thing. what's going on at 3k, turbo spooling, compressing air just starting to fill the pipes. It's not even in the manifold yet. Some, but not all.

Please let's not turn this into "which is a better system" thread. Let me say this again, I am not trying to get the "N20 is OK" because I want one. I don't and as a matter of fact, I'm looking to do a motor swap with a turbo on it and no I am not planning on supplementing it with N20. I just want to know why there are people here who hate nitrous systems. I just want to understand the hate or dislikes.

Such as 95ka24de- He doesn't like the fact that he spent more time and work on his car and still get beat by a stock car with only N20 on board. I can understand the frustration in that. That would just make me work more on my car.

[240SXedUp]

Quote »Now what about the turbo kits? Aren't those packaged for the simple mechanical skilled people? "but you have to get it tuned"[/quote] No, what I was saying is that a turbo upgrade is a specialize setup. There are 10 different things you personally pick out to suit your car. "Should I get this BOV or that one? Should I get a turbo with less hp but spools quickly or a slower turbo that has more hp?" Nitrous is typically just a bottle. I have nothin against nitrous. Id use nitrous if it was given to me. I would just rather have car that performs (and can handle the performance) all the time. When I have a car with good performance 24/7 then ill look into things like nitrous to add to the power ive already attained

Thats still not exactly what i said, you can set up your turbo system up so you have full boost from 3000-7000, and yes, when you're in that rev range and you step on the gas you will have near "instant-on" power.



This graph a decent example of what im talking about (although the particular turbo is too big for full boost at 3000). When you are racing you are going to be in the power band the whole time. To get a nitrous bottle to do the same thing as this particular setup would not only be extremely difficult, it would only be able to do it for short periods of time. Thus, in my mind, Turbo is a much more worthwhile investment.

[raging panda]

I would rather build up a nice turbo kit or something, but that's me, i dont hate on nos. I think of it as more of a running joke among everyone in the world. It does get a bad image mostly because of ricers in the world drilling holes in their stock intake and running 100 shots either killing their engines, or killing onlookers during street races. It's these guys who buy nos for 100bux at your local shucks auto supply, put it on their stock 79 civic with body kit and spinner hub caps, call themselves racers and go out looking to rev on every modded car in a 20 mile radius.

[k6kicker]

any of you doubters...I will gladly put a sprayed KA car up against any of your SR or turbo cars in the straits or the twisties if you'd like proof that nitrous can do more than go in a straight line.

But, Alan is correct, sanctioned racing events other than drag racing do not allow the use of nitrous.

why not a sprayed ka vs. a turbo ka? :ylsuper

[NX95240]

i have a 75 shot on my 95 240sx and it run 14.0 @99.8 1/4 mile on street tires that ok i guess. going to but a SR by this summer.

[Aries]

why not a sprayed ka vs. a turbo ka? :ylsuper

sure When you wanna try this?

So what does that tell you buddy. Why spend $3500 on a turbo kit or $1200 on headwork and cams , when you can spend $500 and go faster (for a shorter period of time) than both. and to those "I need power all the time" guys. Is it really nessesary to have 300 hp all the time (YEEESSS!!). But honestly are you really going to be boosting it everywhere. To school , in the parking lot , on the freeway , to grandma's house. All the poeple I know rarely ever hit boost. Turbo is always there but if you actually used it all the time you'd probably be jailed. Nitrous rocks till' it runs out. lol.

I'm game. Does a 100 mile race sound good to you? :pface

looks like he is going to need two of them, the big ones.

[cstang68]

I believe 1 plus for Nitrous is the streetability of your car. Using a wet nitrous kit you can retain good gas mileage and dpendability. You are less likely to flog the crap out of your car if you havta open up the bottle everytime you wanna squeeze. Yes you can get copious amounts of power out of a turbo system, the drawback(?!?) being that it's always on. To each his own, but i like the idea of having a...well lets face it the 240 is an economy coupe, but on raceday you can turn on the bottle and have a fairly decent (low 14's) car.

[nismofan14]

First off.....its no2 not n2o. 2 oygen to 1 nitrogen

I purchased it because it was cheap. The only thing that sucks is filling the bottle. I planned on a turbo but I needed something to add power till I could get the money together for a turbo setup. Started off with a 75 shot and eventually switched to direct port 125 shot. Still switching to a turbo setup but nitrous kept me happy.
