Evo's have it stock, so do some celica GT-4's. better than having a big guady hood scoop that you cant see around.

lol... good point jason... the windsheild washer fluid (50/50 mix) would probably be the safer of the 2.
i knew the GT4's had water involved w/ the IC system somewhere. i forgot that it was the water/air setup. their scoops werent THAT Gaudy... they were similar to the scoops on the MKIV euro hoods. i just dont want to see any of my bretheren putting a gigantic hood scoop on their car... as long as it doesnt sit more than 2" above the hood, its kosher. if its higher than that, im embarassed to own the same car

So I'm guessing noone actually tried making this yet?
And I had one question about this low pressure/high pressure thing; wouldn't the low pressure area be low pressure because the air is moving over it faster, and the high pressure area be high because the air is slowing down?
If you look at the aerodynamic flow profile it seems that to be the case, it flows fastest over the front of the hood and slows down once it hits the windshield.
Just seems to me faster flowing air would mean more air into the IC in a given amount of time.

Indeed, this is why Formula 1 cars (fia mandated to have flat undertrays) utilize small fins which accelerate the airflow as it goes under the body. low pressure=high velocity, low pressure under a body=downforce. I cant remember who's this was...archimedes maybe, but this is why an aerofoil is created thus, it has a high pressure, low velocity area under and a high velocity low pressure area above. And just the opposite of the formula 1 car, when you have low pressure above and high below, you are met with some lift.

So based on the airflow chart, theoretically, moving the scoop forward would increase the velocity of air that is going into it. This isn't to say that more air is going in there, but the air moving into it would be faster.
I'm sure there's other aerodynamic effects taking place here more than just air velocity, so really the only way to find out is to do it and test it. But this makes me feel better about my louvered hood now! The louvres are in the right place for a better vacuum!

Simple solution guys: FMIC
I assume the functional point of this thread is to improve airflow to the top mount IC hence producing cooler intake temps.... There's a better way.... remounting the stock IC where there actually is some natural pressure difference across it ie. down in front of the car.

Of course this is true, oh and i was looking at my stock IC the other day (it and the engine are out of the car) but where does the air go after the IC? If there is nowhere for it to go, it would build up a high pressure area and disallow low pressure air to enter...my plan is to move it to the front on my project car, so its not really an issue with me, just wondering.
