Nitrous?

[aaa]

Let me know if you would consider adding it, and don't be afraid to explain why.

Of course anything done incorrectly can damage your engine, but if your going to use it I would hope you'd know what you we're doing or would get someone who did to install it. I personally like it. One is the price is normally very small compared to a turbo or supercharger set up and you can jet the Nitrous system to give you the gains you want. Any good condition 4 cylinder can handle a 50 shot of NOS without modifing anything else. Once you go over 50 you'll need to start looking at a higher out put fuel pump and injectors. 75 shot would be fine with this set up. Anything higher on a 4 cylinder you'll need to strenthen the engine internals first.Just to give you a idea what a 50 shot of NOS would do for a base Vibe, say a base Vibe with a 50 shot raced a Vibe GT. The NOS Vibe would hand the GT it's (removed) in the 1/4 mile, Even being a auto! The HP would be the same but the torque output would be much much higher in the NOS Vibe.Nitrous is not a bad thing if it's hooked up corectly and you don't get greedy and use to big a shot. All nitrous does is lowers the incoming air temp into the minuses - Colder air is more dense and the more air that gets into the cylinder the more power you make. Your ECM picks up from the O2 sensor that more fuel needs to be pumped in, to keep up with the very dense and cold air now entering the cylinder. Your stock ECM will still handle the timing and fuel usage as usual. That's a rough example how Nitrous works.

I wouldn't recomend nos. The only good thing about it is that it's the cheapest and easiest horsepower. Unless you plan on going to the drag strip alot it's just not that practical. A supercharger or turbo is much more expensive than nos, but they are safer and the power is always there, and you don't have to keep refilling the expensive bottle.

Nitrous is safe if it's hooked up right and your not going for to much HP. 55HP for a stock 4 cylinder is safe. 75 HP sometimes, but you might need to upgrade your fuel pump and injectors to keep up with the extra HP. Cooler spark plugs would be good also. Money wise $500 to $600 verses $3000 to $5000 for a forced induction system. One of the nice things is you can turn Nitrous off. Your not all ways running extra HP causing extra wear and tear on the engine. It's there when you need it only. You can normally get around 20 races with a 10 pound bottle before it's empty. Reason being you normally don't use it longer than 15 to 20 seconds at a time. It's costs about $35 to $40 to fill a tank back up.It's great for sleeper cars. No one will know you have it and if it's done stealthy even when the hoods up you can't tell until you pull away from the guy your racing.

Since more and more people keep voting that Nitrous is bad let me make it clear that by you voting it's bad I can tell you have no clue how nitrous works, and like I said ealrier in this topic if it's hooked up correctly and you don't get greedy with it you'll have thousands of trouble free miles.

[Flip-Side]

I personally think nitrous is a good way to increase power at a low cost. The systems are fairly cheap, and you only use it when you need it. The only reason I will not use it, is because you need to use it "in shots" for a large performance increase. While it is not used all the time, sudden increases in power and stress on the engine are worse than a "always on" system like turbo or SC.

That was not the question of the poll though. Rather it was asking if I would consider adding it to my car and therefore I voted bad since no was not available. For one, I'm not going to hack through my car to install a tank and secondly I don't see a reason to have one for a car that doesn't spend it's time at the track. I'm not sure about where you live, but if you are caught using NOS it can be a pretty nice fine. Secondly it's very impractical unless you plan to keep the bottle open at all times. I know they make nifty add-ons that can open the bottle for you, but I'm not racing once again. I'm not sure what the original poster's intent was, but don't assume that we are clueless about something if we prefer not to use it.

[DopeVibeGT]

I voted good, but I'm not sticking it on my car. I'll spend the extra $$ for a turbo. No regfilling the turbo needed.

[Fritzburg]

It might be cheaper then a turbo or supercharger, but i'll keep the laughing gas at the dentist...thank you.

[6slinger]

I personally think NOS is great. If I wasn't in Nebraska, I might have it in my car. The other reason for probably not having it my car would be that my wife drives it too!

[d_m_kolb]

I might go with a 25HP shot of Nitrous with the West Covina turbo set up I want. Right off the line hit the Nitrous for about 1 to 2 seconds just enough to get the turbo spinning then let off the Nitrous and let the turbo take over.ya I just might do this. You know everything I want to do to a Vibe I'm never gonna get this thing done. LOL

It is a very common miswconception that NOS wil damage your engine. Fact of the matter is that it is safe and will produce good power gains for a moderate amout of $$. where most of the horror stories come from is people not following the manufactures directions, or poor installation. I ran a NOS kit on my car for 2 years of V8 romping fun with no problems at all. -I do suggest before going out and putting NOS on your car, find out how it works... http://www.nosnitrous.com has a great Q&A section that should answer any basic questions

[coratz]

nitrous/naqz/nos etc... is meant for the race track only. people who use nitrous are generly really hard on their cars. spooling your engine past 3grand and lettin the bottle rip equals trouble!!

Careless/incompetent drivers do.Stop talking about nitrous until you understand how to use it properly.

I had a friend who put nitrous in his car -- he was generally a safe, non-agressive, average driver. He just liked to spook people when taking off from a light, who thought his little sunfire had no pep to it. He'd fly by them and scare the crap outta them. Quite entertaining to watch.

They need to reword the question, or adjust the answers. I don't think it's bad for a car, I just didn't feel it was a good mod for me, you know?

I'm thinking about getting the "Sneaky Pete" NOS system. Here is a description of it and a pic"The Sneeky Pete was designed as a true "cheater kit." This kit will allow a user to obtain that extra tenth of a second without being obvious. It was designed as a very compact, simple-to-use nitrous only injection system. It will be necessary to jet carburetors a little richer while being "sneeky" because no additional fuel source is utilized. The kit comes complete with a super slim 10 oz. bottle, a nitrous solenoid, nylon nitrous line, wiring, 9 volt battery holder, and an assortment of jets."

nitrous only with no additional fuel on a gt also i dont think so! if you really wanna do it get a dyno run(with wideband) to see how rich you are running at wide open throttle(which i suspect would be litte to nothing) and then adjust the jet accordingly. if you want nitrous read more up on nitrous then get a regular WET kit nx express or zex not more than 50 shot.

Although I have thought about the SC, I doubt I would add any warranty voiding upgrades to my Vibe. If, in a year or two, I am able to get the GrandPrix GTP Comp Group then I would consider throwing everything I can find into the Vibe.I know the NO2 is fairly safe and well proven, but I would be too tempted to blow through a damn tank in a days drive. I know myself too well to throw that into my only means of transportation.

I'm sure that kit is designed to make about 40 HP for 15 sec. per bottle on a V-8 race car where nitrous is illegal. They could jet the carb richer for such a small % difference, but you definitely need a system that adds the necessary fuel as well, or you'll be burning aluminum (pistons) instead of gasoline!

If the A/C were to be modified to cool the intake air, that could offer a longer term benefit for available power. A press of the button and nearly instant cold air.The only thing I can think that would be a problem is trying to get a evaporator that would fit and be effective for cooling the volume of air without restricting the flow. I wonder how much refrigerant would be required to make it work?

Part 1:quote:"All nitrous does is lowers the incoming air temp into the minuses - Colder air is more dense and the more air that gets into the cylinder the more power you make".Err, not quite. The cooling effect as the nitrous oxide vaporizes in the intake is a useful side effect, but the main gain comes from the fact that nitrous dissociates into nitrogen and oxygen in the cylinders. Since it is 36% oxygen instead of 21% like air, it's as if you supercharged more air into the cylinder, and so you need more fuel to go with it. An interesting and sometimes expensive fact of physics is that engine RPM is not a factor in how much power nitrous adds! A certain size of jets with the right amount of fuel makes say 60 HP. It will add 60 Hp at 6,000 RPM and it will add 60 HP at 3,000. The problem is that since horsepower equals torque times RPM divided by 5252, when you halve the RPM you DOUBLE the torque. If this sounds good, not bad, consider: If you actuate the nitrous at 1,000 RPM, that 60 HP means you are producing 315 ft-lb more torque than stock! This would likely wind up your crankshaft like a rubber band before spitting it our through the bottom of the block! On the flip side, it also means you can get as much low speed torque as the driveline can handle and we all know we can use all the torque we can get!Part 2:Ford has an experimental truck which uses the AC to chill an intercooler for the supercharger. The problem is that it takes a lot of cooling for the volume of air feeding an engine, so they use the AC to cool down a reservoir of antifreeze, effectively "storing up" the cold for minutes, then using it for short bursts of induction air cooling. On a continuous basis, I think the power absorbed by the AC compressor would equal or exceed the gain from the cool air.

In a perfect system, the output of cooled air could only be equal to 100% of the energy consumed to create the cooled air. You would get no gain from the AC cooling the air because there is no AC unitl that runs at 100% efficiency. Most AC systems only run around 50-70 % efficiency. Thus the energy used would be greater than the energy created.
