I saw this car here-

It's the yellow #917.
I noticed it has ducts in the car that lead from the trans tunnel
behind the driver, up to scoops on the roof, forward of the rear hatch.

Whats up with that? Are they trying to pressurize underneath the car,
some aero trick? I thought the key to downforce, besides wings, was to
*reduce* pressure under the car with air dams and skirts, openings at
the rear? Or is it not an aero trick at all, if not what the hell is
it? I've been around a few race cars but I've never seen this. An
air-cooled torque tube, maybe? ;-)

It's just driving me nuts. Any ideas? Anyone? (Bueller?)

(Yes, I know, I should get a life...)
