Let me get this straight nitrous doesn't put anymore air into the combustion chamber compared to normal???


Now who is backPEDALing? You and everyone else kept saying in "SOME" cases octane "MAKES" more power. That is never the case.


I have actually received tons of thank yous on this site.

One of those very RICERish quotes that I posted earlier was yours.

Everything has been addressed. I know nitrous isn't FI, I never said it was. I know that octane doesn't make power and hopefully you do too now. What else needs to be addressed?

So now its not post count or join date, it is age and the car you drive. Well my guess(don't really care) is I am close to your age and drive a better car except you get better gas mileage.

 

Manifold pressure never increases because of nitrous, so no, it doesn't add more air into the combustion chamber, it richens the oxygen mixture.

I wanna hear your explanation on how nitrous is "mostly" forced into the engine.

 

so then to settle the arguement, what do you drive and how old are you cobot?

 

Exactly...it's the same volume of air, just more of it is comprised of oxygen than the air we breathe. It's like mixing more sugar in your tea.

 

So uh, you mean to tell me that you never said Nitrous was forced induction? It seems to me that if you knew it wasn't forced induction, there wouldn't be 6 pages of posts explaining to you that it isn't. Had you simply said "I stand corrected" I don't think this would have gone on as long. And you still refuse to beleive that octane plays a roll in HP production in high compression/FI motors. And you still haven't answered as to whether you are old enough to drive, or in fact own a Cobalt.(These are really nice things to have when you are on a Cobalt Forum) Stop trolling.

 

Oh REALLY???? NEVER?!?!?!

God, I didn't even have to resort to your tactics of reading everyone's post history to prove you're an idiot on this one because it's right here in this thread:

Now how bout you find some other forum to troll? You've worn out your welcome here.

And BTW how come the mods are all over an off-topic thread in the off-topic section of this site like a fat kid on a cupcake, but this garbage has gone on for multiple pages and yet no ??????

 

ok both wrong but alley cat way less so

itrous is fnorced chemical induction...ur using 1100psi of pressure to force n02 into the intake stream. The compression breaks the n2o apart contributing its o2 to the reaction...this is why u have to add fuel to run nitrous.

next nitrous doesnt increase the compression ratio...copression ratio is betermined by piston deisgn and head design and is the ratio the air is compressed from btdc to tdc iirc.

But Cobot...go troll elsewhere u havent added a single useful thing yet

 

Correct. There is no initial increased pressure in the chamber. It provides a chemically enhanced mixture of air that undergoes a chemical reaction to release more O2 for combustion.


Umm... I didn't backpedal. I never said it ALWAYS makes more power. I stick by what I said. In SOME cases you can see performance increases by using higher octane fuel.


None that I saw... but I'll take your word for it and congratulate you. Congratulations.


I know exactly which quote you are talking about... and it was taken out of context. Congratulations... you can copy and paste a post that has nothing to do with this thread and make it look "ricerish".


You still avoided the argument. You originally said octane has no effect on power output of an engine. I provided reasoning why I think it does. You said, "No you're wrong, I'm right" and left it at that. That doesn't address the explanation I gave...


No... I didn't say your knowledge of cars is based upon what you drive or how old you are. Don't try to twist my words around and make it seem that's what I was implying. I simply wondered if you had a Cobalt. Here's my question: If you drive a better car, why are you on the Cobalt forums? Why, if you're old enough to have a real job, do you have so much time to spend on a Cobalt forum in addition to whatever websites you must visit for your "better" car too? My question about your age and car was only meant to provide some insight as to why you are on this site in the first place.... it had nothing to do with your knowledge of cars. But thanks once again for attempting to turn my words around and then throwing out a low key insult about the car I drive.


Here's an idea... why don't you get off the personal attacks and get back to the issues that we were discussing in the thread...

 

So where did I say they are the same???

 

I'm still waiting for the "mostly" forced explanation.

 

Excuse me I was wrong with that, it doesn't increase compression ratio, but it does DRASTICALLY increase cylinder pressure, which is what I meant.

 

Explained more than once, I hate going in circles.

 

Post number where you explained it please.

 

Search

 

Not found.

 

Yeah the search does suck on this site.

 

It only finds information that was written here.

 

Try again.

 

Seriously... I'm done with this thread. This is going nowhere and has turned from a legit post to a discussion on nitrous into a childish game for a troll.

 

Does nitrous not increase cylinder pressure?

 

CoBOT, you've made quite an impression on this forum in your first 13 days. Congrats!

 

Wow...I think I see why the American education system is laughed at in other countries...

 

I agree with you on this one.. NO ONE will race me, since I got my 03 Cobra March 20 2004, on the street I've had ONE race that I didn't instigate, and that was against a 01 Mustang GT ragtop.. (we met up later at a dyno session, and he made about 250 hp to the ground) and wondered why I pulled away from him so hard, till he saw the 372 hp I made at the wheels..

 

So does driving in a colder climate vs. a warmer one. Cold air is more dense than warm air, hense the increase in cylinder pressure. Nitrous has a higher density of oxygen molecules than the air we breathe. That doesn't mean it's pressurized beyond the air we breathe, though. So yes, cylinder pressure will increase as a result of nitrous, but that doesn't mean the air is being forced into the cylinder.

 

Not entirely true... nitrous oxide undergoes a chemical reaction once it hits a certain temperature....
2 N2O + heat ----> 2N2 + O2. For every 2 moles of N2O, you get one mole of Oxygen molecules. So technically nitrous doesn't have a higher density of oxygen molecules... it just has the potential to release more under the right conditions.

But yes... it isn't pressurized when it enters the cylinder.... hence it's not forced induction. Think about it... forced ... maybe additional pressure in the end... but induction? It's not forced during the induction.
