As we all know hot air rises. That being said, cold air is denser and lower than hot air. Cars like colder denser air. Makes them go more better.
Why then do vehicles suck air from above and blow it out below? Air intake is usually near the top of the engine and exhaust from headers on is below the engine.
Wouldn’t it make more sense to suck air from below the car and blow it out from above the car. Point headers up at the hood and blow it out that way?
I understand the whole - it doesn’t look pretty and gets in the way of seeing things on the hood. I got it. But people who mod cars for performance - wouldn’t it make things more efficient?
