Weird air ducts in a racing 928

	I saw this car here- http://www.928motorsports.com/other928s.html 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. http://www.928motorsports.com/othercool928s/928GTrenNLBIG.jpg http://www.928motorsports.com/othercool928s/jpk02big.jpg 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...)

I'd guess the ducts are an attempt to cool the transaxle.

	So the consensus is, they're cooling ducts, most likely a trans cooler. Hmm. Seems like a lot of air to me. Thanks, All.

	Billy Bad AssrВ© wrote:> cools the brakes >> notice the front bumper has them as well!!! There's a side view of the car that shows ducts down low on the rockers, ahead of the rear wheels. That seems a more apt place for rear brake ducts. http://www.928motorsports.com/othercool928s/jpk02big.jpg Trans cooler makes sense, I guess.
