What do these vents cool? LoL

[crustychief]

Maybe they were installed to prevent the car from lifting the front at speed (or achieving that speed) since the front doesn't seem to have a splitter.

[Oh Haha]

Isn't there a Pelican close that could take a look at this fine 911?

Based on my expert engineering analysis of those ducts I have determined that they are in fact a very well thought out race modification. Anyone who has driven a rear engine car at high speed on a track will know that there is very heavy braking involved while approaching a tight turn. In this case, they have set the brake bias heavy to the front brakes. When you stand on the brakes, the rear of the car goes airborne, thus placing the duct openings for maximum cooling of the rear brakes while they are at the highest point in the air stream. I am assuming of course that the car is capable of a maximum velocity of approximately 350 mph. It does have nos, so depending on the duration of the "squirt" that is not totally out of the question.

Thanks for the excellent assessment of the well-engineered rear brake cooling ducts. The only question which springs to mind is this: Given the terminal velocity of the aerodynamic profile on this car the only way I see it, reaching your well calculated maximum speed to extract the efficiency of the ducts is if the car were to be placed in the belly of an airplane which could reach that speed. If that were the case I still don’t think those well engineered ducts would be of much value.

Speaking of well engineered aux braking. Here is another example of "bending the rules" with a well designed air brake system. Not shown in the picture is the complicated amplification pulley system. Attached at the top rear of the wing is a rope that goes thru a set of pulleys with the last being attached to the roof directly above the drivers right shoulder. At the end of the rope is a loop that goes into the cockpit and around the drivers right knee. With proper extension of the right leg against the brake pedal, the rear deck is quickly drawn up into the air stream thus quickly slowing the car.

What about the accelerator pedal you ask. That has been addressed with a fly by wire system. Electrodes attached at each corner of the drivers mouth control forward speed. The higher the edges of the mouth are drawn up, the faster the car goes. A fail safe has been built into the engine management system so that if the mouth gets out of control, the engine explodes culminating in a cloud of blue smoke, which quickly lowers the edges of the mouth, thus stopping the car.

All of this is perfectly legal according to the current ALMS rule book.

I think that is a vintage aluminum "raydyot" exterior side mirror being used in place of the stock rear view mirror. Needs it low to see around the roll bar I suspect...
