fiveohpatrol wins my first award for finding one of my flaws.

Obviously the air does not become denser as it compresses--only colder. However the air fuel charge IS a much denser "charge". You get extra cylinder pressure when the denser air/fuel mixture heats up under the compression stroke. This is where the extra horsepower of ram air is created.

No......The air being pulled through your manifold is over 500 mph. You would have to exceed mach 1 in order to pressurize the carburetor or FI system. Do you see this?????

FiveOhPatrol! Awesome!!! Good catch, I did not expect anyone to call me on this one. This is like post grad level internal combustion engineering!!!!

YOU ROCK!

By the way, some gases will become more dense as they pressurize and will change states from gas to liquid. Liquid Hydrogen, Nitrogen, and Oxygen are several gasses that do become "dense" as a function of their compression. In physics we like to say it is not dense but just a change of state from liquid to gas and back, but a "chaos" theory mathemetician would dispute the physics instructor from now till the end of time.....

I guess I fall somewhere between the two pencil necks. Gotta love those of us who refuse to pick sides......



MOST EXCELLENT.
