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/otherc...GTrenNLBIG.jpg http://www.928motorsports.com/otherc...s/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 would worry less about the air ducts and much more about that vertebrae-crushing setup on the shoulder harness. A good frontal hit, and that harness setup - with no support at shoulder height - will exert a lot of downward pressure on the spine. -- Bob Paulin - R.A.C.E. <>< Race Car Chassis Analysis & Setup Services Chassis Blueprinting Services (as in engine blueprinting) |

Ducts like those usually feed air to oil coolers (transaxle, differential, etc.) Its much easier to get a lot of airflow by sticking the scoop up on top of the car and ducting the air down to a cooler mounted in the floor pan than it is to mount the cooler up high. |

There should be a bar across the back, higher up, to mount to. Instead, they're bolted to the body? |

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

That seems a more apt place for rear brake ducts. http://www.928motorsports.com/otherc...s/jpk02big.jpg Trans cooler makes sense, I guess. |
