Aerodynamics doesn't become a significant factor until highway speeds, like ~70 mph and above.

I guess you havent ever driven with a roof rack or a cargo rack on your car. it make a difference, drive down the street with your hand out the window and tell me if you can't feel the wind resistance against your hand. ball your fist up, then make it flat. Try it, and see if you feel the difference.

I know I'm not going to influence a dense mind with science. So I'll offer one more thing to try if you really dont think that your aerodynamice of your car doesn't make a difference in your acceleration. Place a big piece of plywood to your bumper so its perpindicular to the road flat side facing you (the driver)... now drive as fast as you can for your 1/4 mile...(hopefully you will drive faster than dwapeni's 70 mph 1/4 mile? So now that you have your inmpressive 18 sec 1/4 mile take that dumb looking board off of your car and do the same. Again proving that your aerodynamics will make a huge difference in your time, in a 1/4 mile...
I can't believe you said it doesn't make a diff at speeds around 70 mph, I surely hope that you can get your car going faster than that after a 1/4...
oh one more and my last example... the Maxima SE & the I30 t.... same engine, same power, different frontal area's. I have seen threads for the last week talking about how Maxima's are just a little bit faster than the I 30. The I30 is a little heavier than the SE, but so is the SE to the type R.
Oh if you want to read an article about this, Sport Compact Car,august 2001, page 298.

Of course aerodynamics makes a difference, just not as much as you'd suggest. The fist example is fine, but that's the force of air against you. The Max punching a hole thru the air at 70 mph will not feel that much resistance compared to the 190 horses it is using to push the car forward. It's all relative. And, the aerodynamic differences between the integra and the Max will not be that great. What, 0.29 cd vs 0.31? Both cars are aerodynamic. It's almost redundant.

the Acura NSX has .32 and a lamborghini countach has .40 there is a difference of 74 hp, but both top off at 178. so the difference of .08 makes a heck of a differnce.
it takes a 98 Mustang GT(.34cd) 46hp to go 100 mph, but it needs and additional 51 to go 125 and 181 to go 150mph.
and it takes an 01 golg GL (.31cd)44hp to go 100, 87 hp to go 125 to go 150mph. Why is this....class...Aerodynamics you can't deny it. I know I'm beating a dead horse, and over reacting about it. My point is that extra 5-10hp it takes my car to do what yours does, makes a difference. Did you not feel any difference when you strapped an intake on you car? or a down pipe? These things only increased your HP by a few digits each. But to reduce that drag that little will allow your car to use less power than the other at all speeds. Look at the difference between the example I took out of that article... over 30hp difference needed to punch that hole and only a difference of .03cd. What can you do with that extra 30 hp?

turbo type r has a very good chance of beatin sc max only because it has a better aftermarket supplies. typer can get cams headers and all that **** and lower there compression and **** so it would be hard to compare the 2.

So, some just run the quarter with their windows and sunroof open and then run the quarter with them closed. That should show just how much drag effects speed right?
