Scion owner: forward facing scoops (ie turboed Subarus) cause cars to hydroplane

my head hurts from such bad physics.
Wait, maybe this is why Subaru's understeer. Less grip in front, ahaha
Foward facing scoops (think Subaru Impreza WRX/STi) does brings air into the engine bay, but it all doesn't go into your engine, most of the air has to go somewhere? Where? It hits the firewall and goes under your car, causing a lift and possible hydroplaining in the rain.
Rear facing scoops like the one on the S2000 pictures above doesnt pull air into the engine bay, but rather creates a path for the air to leave the engine bay, therefore the air comes in through the grill, and goes out the scoop rather than under the car. You can also get more downforce from this set up.
For the Scion's you might want a reverse scoop like on the S2000 above, you will get more downforce and your engine will stay much cooler. If you get the foward facing scoop youre gonna hydroplane easier.

So the guy on that Scion forum is incorrect. And I don't care.
I don't even know what a Scion is!

Air actually enters the rear-facing scoop under slight pressure but not enough for any real supercharging effect, just cooler outside air above the dirt and grit at road level.

Neil Crawford actually redesigned his COBB intake on his RS to work as a Cowl Induction intake. He named it Bob

Now, I could see cowel induction on this car...
I kid, I kid.
Bob was good for some decent gains, if I remember correctly.......
