While what you posted is mostly true, you can't speak for all speeds - the way air moves over the car at 35mph vs 100mph is very different.

I've found that cooling was better, and the intake charge was better (my itb's are at the cowl).

If its for looks, then yeah that's dumb.

Jerrel...what's been happenin'? Long time no see.
I'm more than happy to hear what you tested and the conditions you were testing in. What cooling do you speak of? What all parts were involved/installed? How did you do your measuring? I'm really always open to learning, listening and a good level debate.
I know there are benefits to sourcing air from the cowl (we're all pretty familiar with cowl induction), but any properly designed setup is going to source air from the cowl and be sealed off from the rest of the engine compartment. It really is a great way to get good, cool air to the intake- when done correctly. Why wouldn't you have a nice plenum or cowl induction box on the ITBs and source air for them without compromising airflow?




General post for the thread:
Yes, I know the world is not a race track, and we don't need race car setups to get around town. But if there was any benefit to it, would you not see it designed into cars in general? I know there are vented hoods out there, and that even some cars have them from the factory, but such parts are in completely different locations on the car and are designed into the car. Much like a lot of the old muscle cars with factory cowl induction- but a look at any of them will show a system where the air from the cowl being used for induction is isolated so its sole purpose is to go to the intake.

As seen here-
