N/A is exactly that. Normally aspirated. IE it's not being force fed any air from a supercharger (blower or turbo or house fan, doesn't matter ). You can put nitrous on a normally aspirated motor, and it's still pulling the air in there of it's own accord, it's just the air it's getting is a LOT more potent. It's STILL N/A though...

All motor means your making power with the motor only (no external power adder at ALL). No nitrous, no blower, no nothing. Just mother natures air, good parts, and good tuning.

Running fast N/A is cool.

Running fast all motor. Thats VERY cool

This is correct,ALL MOTOR=N/A with NO power adder's.......

N2O is a power ADDER.IF you don't believe it ask NHRA,or anybody that runs Pro Stock.

 

IMO, n/a and all motor are the same. It means NO nitrous. As you can see though in my sig I used "ALL MOTOR" so their was no confusion.

 

If you run Nitrous you car is still Naturally breathing air in...meanings the air is not being forced in with a turbo or supercharger. Nitrous is not forcing air into your motor there for you are still N/A with Nitrous!

 

In my neck of the woods you say n/a to try and play off the fact you plan to spray. The n/a and N20 deabte has been going for years. We say N/A hoping the other party thinks all motor, and then they get sprayed on.

N/A = Nitrous Assisted

 

I personally feel that spraying 1100psi of nitrous directly into the motor is not naturally aspirated. Maybe if you sprayed it out in front of the car and it got sucked in my the motor, I would consider that N/A. Otherwise N/A=all motor.

This is stupid soon people will be saying "oh yea i'm stock" and they really mean just a stock block. Wait its already happening in honda world!

 

I have never heard of nitrous on a motor and it still being considered N/A. I've always heard N/A = all motor. Its not "forcing air" in but it's still not "natural." I dont drive down the road and occasionally hit "pockets of N20" floating around and feel my car accelerate. You're putting it there, thus to me it's not natural.

So in short, to me anyway, N/A = All Motor.

N/A is not the same as "All Motor."

Natural aspiration is using atmospheric pressure to fill an engine's cyldiners with air. Nitrous is part of the air/fuel mixture, and the change in the a/f mixture is not the same as how the engine "breathes." Aspiration is breathing, or in an engine's case it's how engine vacuum and the absence of pressure is used to pull air into a motor. A car with nitrous is still N/A off the bottle, as it is on. The only time you're not naturally aspirated is when air is pressurized air is being forced into an engine instead of the atmosphere naturally pushing the air in. Nitrous is not forced into the engine in any way.

 

Well said

 

OMG



I can't believe some of the post on this thread . NA means naturally aspirated. It is THE SAME AS ALL MOTOR. Nitrous is not natural aspiration. You can try and twist it any way you want, but our atmosphere does not NATURALLY force severall hundred extra hp worth of oxygen into a given engine. Only way to do that naturally is with more radicall engine parts. Nitrous is a POWER ADDER.

(And yes i know cams and heads ADD power, but unless someone is trying to be an idiot, they get the point.)


Naturally aspirated = NO power adders. Nitrous is a power adder, and in a similar way to blowers and turbos, is basically forcing or adding more oxygen than an engine can NORMALLY BREATH in.


I can't believe so many people are posting that nitrous is NA. I thought stuff like that was common sense to even novice or newer "car buffs".

Like someone said before, try to spray in a Naturally aspirtated class like Pro Stock and you will be out.

 

With nitrous you are forcing more oxygen into an engine that it can take in normally or naturally with the given parts that it has. Just like with boost.

For instance, an average heads and cam lt1 can make say..... 400 rwhp with a 306 cam and ported heads, now if it makes 600 with a 200 shot. You just forced an extra 200 hp worth of oxygen into the engine that it could NEVER normally make with its given parts. If you had not ADDED the 200 shot, the combo could not EVER NORMALLY "BREATHE" or aspirate in enough oxygen to make 600 hp.


I do agree that when you are NOT spraying , the car is naturally aspirated, but when the nitrous is activated it is NOT anymore.

 

DAMN!

guess all this brings up my pet peve TRUE DUALS. What there are false duels? Did they lie under oath? you get the idea apples, oranges or in some cases chainsaws, footballs

 

Yea, thats what im thinkin. If you have nitrous equipped on your car, it can still be N/A, and when you spray then its no more "natural". So with nitrous you can be both.

 

But you're really not forcing the nitrous into the motor, the atmosphere is pushing it in. Nitrous isn't forcing more air into the motor, it's altering the air that is pulled into the motor.
