Good Mythbusters on now

Trying all the fuel saving devices:blink:

 

[Tim Turner]

I'm watching it now. So far the magnet and acetone in the gas have been busted in proving that they increase MPG.

 

[Nelson Atwell]

I'm watching it too. I'm sure it will all be busted.

 

[Jeffrey Travis]

Yankee vs Red Sox is on............even sans 'roids, it's all about the long ball.

I want to see them revisit this.... I want them to test the tornado, the electric blower and things like that. I also think they should do the tests on the road and not on a dyno.

 

[Mike Wilson]

Hmmm?

A little nail polish remover and a refrigerator magnet to double my gas mileage?

I'm going to run out right now and try it!:huh:

I also think they should do the tests on the road and not on a dyno.

I prefer tests on a dyno verses the road. The reason? On a dyno, everything is controlled.



Like the test with the trucks one with the tailgate up, the other down. Tow identical trucks. Well, not really. No two engines are exactly alike. Each engine is slightly different then the other. Two identical trucks are slightly different. Even tires are slightly different. So, when they tested both trucks, the one with the tailgate up might have had a better tire, better fit and finish over the other, and a slightly "better" engine. Was it the tailgate or could it have been that the tailgate up does make a difference?



A wind tunnel would have been better to prove the theory.

Caymen,

I agree. See if you follow me on this. Tailgate/Wind resistance for the example:

If you were to perform this test on an outside test track, you would have variables in the

wind resistance that you could not control, the "Aerodynamic" part of this example.

If you were to make one run in one given direction to test the C/.d ( Drag Coefficient)),

you might get one specific reading. Then, on your second run say the wind had changed

direction, and was head-on vs. tail wind. This would drastically change your outcome

for those specific tests. And lets not forget the part that humidity plays in this equasion.

Moist air is denser, therefore harder to go through, than drier air. These variables cannot

be controlled in an outside environment.

On a dyno, they can, however compensate for most or all of the variables related to vehicle

weight, horsepower, torque, etc... In other words, the static versus the dynamic variables.

Aerodynamic testing is better left to a wind tunnel.

Ouch! My brain hurts now!:wacko:

Did you even watch the show? Forget the road test, the wind experement showed that the tailgate up had less drag than the tailgate down. Dude, you over anulize evereything and suck the fun out of almost every thread you post in.



Ape Out.

 

[Mike Wilson]

Ape,

I don't know if you were replying to Caymen's post or mine. But it will all be the same in the end. I wasn't trying to suck the fun out of anything, just trying to give an honest observation

on what I know to be true, and what I had seen on the show before.

But I promise I will "analyze" my post and see if there is any "over-anulization" I can get

rid of!



Luvya Ape!

tracnblack out.

Tracnblack,

Moist air is denser, therefore harder to go through, than drier air.

Obviously you are not a pilot. While most believe moist air is denser, it is just the opposite. High humidity makes the atmosphere less dense. Moisture is H2O [atomic weight = 18] which is less dense than the major atmosphere component,i.e., N2 [atomic weight = 28]. High humidity increases takeoff and landing distances because the air is less dense. On a hot, humid day, flyballs go farther [more home runs]. Both heat and high humidity reduce atmospheric density.

yea... what they said!!!lol:unsure:

 

[Todd Z]

Send them an email, they do read them...

I would like to see a revisit also..

[Mike Wilson]

Bill-E,

Thanks for the lesson. I will try to learn a little more on this subject before I post

anything on it again!

Water, or H2O, is an amazing thing, anyway. If I am not mistaken, is it the only

substance (in it's natural state) that expands, rather than contracts, when freezing (to

a solid state)?

I have learned something new today!

 

[TomT]

I learn so much on this site!
