I think you missed the point. You can't take a term that has been in common use in the automotive world for decades and give it your own meaning. Naturally aspirated is the term used to describe an engine that does not used forced induction. That's all it has ever meant and nothing has changed.

Look in the glossary of any engineering textbook on engines and you will find the definition I've stated with no mention of nitrous oxide or any other non-mechanical enhancement.

You can argue your own meaning all you want, but it don't mean squat.

 

I don't see how N2O isn't forced induction. Or at least a form of it. I realize it's not full time forced induction, but a concentration of the stuff is being sprayed into the intake.

To me that's not a natural vaccuum from the engine pulling the stuff in.

Apsirate in the dictionary reads (the closest term that could be considered engine related):

"To draw (something) into the lungs; inhale. "

Natural (in conjunction with aspirate) would mean to just draw (something) into the engine at a natural atmospheric pressure.

N2O is being sprayed in a concentration into the combustion chamber. It just doesn't seem like it's doing all the aspiration work anymore with it being sprayed in.

The same could be considered with an athsma inhaler. As you breathe in, you spray a concentration of chemcial and oxygen into your breathing passages, which being in such a concentration work to cure your difficulty in breathing.

Sure the same would work if you just stood in a room of the oxygen and the chemical that had no pressure charge, and naturally aspirate all of it into your lungs, but it doesn't work as fast as when it's sprayed (or forced) into your breathing passages. When having an attack, speed of the cure is essential.

I would never usually argue you NZ, you have proven yourself time and time again on the forums. I'm really looking for more of an enlightenment from you rather than an arguement. Just sharing my point of view to you and hopefully you can relate to see why I feel it's (temporary) forced induction.

 

Black132B, you are breaking it down far to much.
Yes, if we got technical, N20 is not N/A. However, in the automotive world, for the last 50+ years, N/A means non-forced induction, no turbo, no SC, etc.
According to IDRC, and NHRA Rules, N20 cars can run in the N/A class.

 

Ahh I see what you guys mean.. If it isn't full time FI, then it's N/A according to those rules.. Fair enough.

Regardless of the rules from the past, It's not actually naturally aspirated when in use. That's why I'm not a big fan on N2O. If you're gonna do something to boost HP drastically, might as well go Turbo of S/C. That is just IMO.

 

So.... when i put the microtech on my car, I can install nitrous on it at the same time, then I will be the first street 6-port FC into the 13.... wow, thats fairly easy then, why hasnt anyone else done that???

 

So that means you get the microtech for free right? cuz its still N/a
