Hey guys,

I have to ask a stupid question, knowing its stupid, so please bear with me. I have never seen nitrous in action (or meth) and know no one who has it (unpopular in my area). So, I know close to nothing about it. Therefore, I have a couple of questions.

1. What exactly do nitrous or meth do to a car?

2. Is it legal in most areas? Races?

3. What are the dangers of it and does it do damage to the car?

As for the differences between the two, I have found threads about that, but knowing so little the threads are hard to understand.

Thank you very much for your help, it is well appreciated.

N20 is a power adder per most scantioning body rules, some allow it, some don't.
- it is injected into the intake tract and under the pressure and temperature of the combustion chamber dissociates into Nitrogen and Oxygen. this extra oxygen in the cylinder allows more fuel to be injected, thus more power.
- there is a danger of running lean with N20 if insuffient fuel is added (dry kit) and it's not cheap to refill the bottle.

Alcohol/methanol injection is used to increase the quench effect within the cylinder and allow you to run higher levels of boost prior to getting detination/knocking.
- methanol is corrosive and can damage seals and some plastics.
- if the alcohol tank runs dry under use, the car will knock if the boost isn't reduced (most if not all kits have a failsafe for this occurance)
- prolonged knocking can cause catestrophic engine damage.

 

there not stupid ques. just ques. that require long answers..

 

Nitrous Oxide is basically an oxygen accelerator. it adds power really in 3 ways. at about 800 psi the nitrogen seperates from the oxygen. bringing more qxygen to teh "party" means more power. you get a small amount of power from the nitrogen as well. nitrous is also very cold. something like 200 somthing below zero. for every 10 degrees temperature drop you gain 1% horsepower.

dangers: too much of the Nitrous monster will grenade your engine in a heart beat. the problem is you get greedy. 50 shot feels great, lets go 75 shot and so on. Hot rod mag did a nice series on the nitrous monstor a few years ago. if you dont bring in more fuel to help cool things down you will melt down in a hurry. typically tehre are wet and dry systems. wet bring more fuel through the nitrous nossel, dry systems typically will increase fuele pressure and bring the fuel in teh normal way through the injector.

every 50 horse or so nitrous shot you use, you must pull timing out. i believe its 3 degrees per 50 horse. my MSD box on my Impala does this for me when i hit my button. if you dont pull timing out you can detonate. as you detonation kills. I run a 175 shot on it.

you can have a nitrous backfire "hic up" that could start your car on fire.

you could forget to turn off your bottle heater and explode your bottle and rip your car in half i.e. nitrous express system with a nissan maxima a few years back were the prssure relief valve failed a ripped not only the car but part of his house down too. boom.

nitrous is very safe at sain levels though. i cant repond to how well they work on EVO's though. Bang for the buck is awesome with nitrous.


higher octane fuel burns slower and is less volatile the lower octane. i guess you can think of it as lower quality. burning slower prevents detonation. 100 octane race gas is less prone to detonation because it burns slower. alcohol injection does basically the same thing for less money. less detonation means more boost. boost is goooood yea.

hope this helps. i am not an expert but i use nitrous all the time. and for gawd sake please dont call it naaawzzz.

 

I use a NX Express wet kit with the 50 hp jet set up. I also use a NX intercooler sprayer and that makes a huge difference in warm weather on the stock intercooler. Not as noticiable with my Buschur FMIC though. The wet kit still hits like a hammer though...very cool and no damage...so far .

 

Thanks for the replies, they were very helpful . Now I shall, God willing, begin reading through the threads on the subject . I feel quite a bit less lost now lol.

 

get some nawwzzz!!! lol sorry had to
