My question about the Nitrous, and correct me where I am wrong PLEASE, but PLEASE dont flame only inform

Supercharger - Compacts the air and forces into the engine via a pulley, meaning good boost but a limited boost that doesn't really increase.

Turbocharger - Removes 2 parts of something from the exhaust, compresses with air, and pushes back into the engine, meaning boost only after starting up, but the longer you run, the more boost, but heats engine up extremely hot...

Nitrous - Adding Nitrous Oxide into your Oxygen flow, only adds boost when wanted, but creates extremely hot engine temperatures way higher then the other 2 Aspiration techniques.

So why would we want to put nitrous into our cars? I have been hearing the 2.2. and 2.4 both have trannys in the Manual that are almost maxxed out. We would just be signing the death sentence to our engines, unless we bought/forged pistons, and lots more components... ARight?

First, dont worry about anyone flaming you, we were all noobs at one point in time. You sound like you know some **** about FI. Pretty much everything you said was right on the money, but the part about the tranny's being maxed out, i dont believe. Im sure you've read specs on the getrag and saw that the maxium gearbox torque is 170ft lb. I garuntee you the getrag could prolly handle double the amount of torque its meant for, the only thing youd need to worry about is a more aggresive clutch. Other than the the tranny's arent just gonna stop working once you hit 190ft lbs of torque in them, i've had experience with these before and they can definitely hold their own when it comes to torque.

 

n2o works great with turbos if you have a larger turbo that takes a while to spool up before providing some boost. the nitrous would be used to help the turbo spool up faster.

with superchargers, there isnt much that can be done outside of adding a new pulley, that is going to increase boost. so nitrous is a possible solution to adding more hp.

for your turbocharger, its boost varies on the engine rpm, not on how long it has been running.

 

The supercharger part, you're basically right...except 2 things...a supercharger is still a type of compressor, so it compresses the air just like a turbocharger. As far as it being "good boost", I'm not fully sure what you mean by that.

The turbochargers part, it works the same way except your turbocharger is spinning according to exhaust flow. As far as how fast is spins is all according to the turbine inside the turbocharger (a/r on the exhaust side). The part where you said "boost only after starting up...etc" is kind of false. Like I said, a turbo spins according to your turbine inside your turbo, so if you have a smaller a/r turbine, it will spool faster because of it's size making it easier to spool, if you have a bigger a/r turbine, it will spool slower because of it's size. There are turbos out there that will be at full boost at 1500 RPMs and then you have some that will be at full boost at 4000 RPMs...it's all according to the CFM of your exhaust ports and the turbine.

Now with the misconception that because a turbo runs off of exhaust flow, that the temperature of the heat entering your motor is going to be extremely hot. Turbocharged and Supercharged applications run about the same EGTs (turbocharged applications usually run slightly higher). You have to remember that the reason your EGTs run so much hotter is because of the air being compressed regardless on which source of boost you're going with. Ask anyone who owns a supercharger, those suckers heat up and get hot as well.

As far as nitrous goes, you have to understand how nitrous gains you power. Nitrous is N2O (1 part nitrogen, 2 parts oxygen), so when it is being sprayed into your motor, the heat from your engine breaks down the nitrogen and you have oxygen left over, which everyone knows, the more oxygen that gets into your motor the more power you will gain. As far as temperature, I believe you usually run the same temperatures as n/a because you aren't dealing with compressed air.

Hopefully this gives you some insight on some things. If you have anymore questions you can ask me privately or reach me on our new forum (check the sig). Peace.
