I'm asking this on this site because there are alot of knowledgeable people that post here. An old school Mustang bag of bolts relic friend of mine believes that anything fuel injection can't be normally aspirated. I believe that N/A can be carbed or fuel injected, just not nitrous or blown. Who is right? can someone settle this diagreement so he can get on with his life! lol

 

you are right, just no forced induction/nitrous

 

Naturally Aspirated

 

+10000000

 

Lets break down the words.

Natuarally -
In a natural manner.

Aspirated, Aspiration -
Coming from medical terms
-To remove an abnormal accumulation of (a liquid or gas) from the body by aspiration.
-To suction (a body part or growth, for example) for the removal of a liquid or a gas.
-To draw (something) into the lungs; inhale.


My take -
Natural aspiration would mean the engine gets its oxygen by the natural inhalation of air/fuel caused by the difference in pressure inside the cylinder as the piston moves down relative to the ambient and not by force (supercharged, turbocharged) or chemically (nitrous).


Whether the fuel goes through a carburetor venturi or a fuel injector is irrelevant. Tell your friend that you are right.

 

You are right 100% and the old school rustang friend is wrong!!

 

Hey thanks guys, can't wait till he reads this thread! He was blue in the face trying to correct me- the nerve of this guy!


I'm just glad I was right.........for a change!

 

lol .. all you can do with someone like that is laugh. I'm betting this chap would argue with a fence post ... too funny!

 

ha what really gets people like that going is if you say "no, your wrong" to every point they make. don't follow it up with any facts or knowledge, just look at him and say.... you sir, are wrong.

 

Your friend is wrong, my boss thinks the same thing too, hes an ***.

N/A = Naturally Asipirated = breathes on its own with no ventilator(aka, blower, turbo, nitrous)

As good an analogy to medical i could think of.

 

Wow, he is real old school. At one time, he would have been right because only a carburetor-equipped vehicle was considered normally aspirated. But that was at least 25 years ago when EFI was just starting to become more common from the factories as standard production. At the time most major car magazines would actually make a big deal of a production EFI system and was considered exotic. A perfect example of this was the GM TPI system. Evntually as more and more vehicles were equipped with EFI it was considered N/A because carbs were phased out of production.

 

Aspirated being the key word here, by very definition we are talking about how the engine breathes, which it does under its own power without "forced induction", or higher than normal pressure shoved down its throat.

It doesn't matter if it gets its fuel from a carburetor or a fuel injector, that has nothing to do with "aspiration".

For what its worth, you can run a carb with EFI...

 

Wow, you can always learn something new. I thought NA meant Nitrous Assisted.

 

Wow, he is real old school. But that was at least 25 years ago.
O yea, he is all of that

 

HAHAHA!!! good one.

 

I look at N/A as burning oxygen that would be ingested under "Natural Atmospheric" pressure.

 

agreed

Hey Hawk, is that a NA 10 sec. bird?

 

Yes, see sig below for times.
