Guest Anonymous Posted November 13, 2002 Share Posted November 13, 2002 Hi ya'll, long time no see. Anyway, this is a question for the guys out there that have performed aero tests on their z's (I will do a tuft test myself but thought maybe someone out there has already done this). Question: is there suffiecient pressure to duct the rear brakes from the side quarter windows? If not, how about from underneath the car. Thanks.

johnc Posted November 13, 2002 Share Posted November 13, 2002 Is this an endurance racing Z? If not, you probably don't need to duct air to the rear brakes. Some ITS guys do when they run longer events but they just run the ducting underneath the car and pull air from around the front of the diff.

katman Posted November 13, 2002 Share Posted November 13, 2002 John is of course right, rear brake cooling is generally not an issue even in ITS racing. The undercar ducts because of their ground proximity usually just serve to redirect small pebbles and other foreign objects into the brakes. For a quarter window mounted NACA duct a la NASCAR it'd probably only be effective with the door windows up because of the sharp leading edge and goofy airlow about the rear quarter with the door window down. Note the smooth leading edge of the B pillar on your typical Winston Cup car. They also put 3" fans in line with the ducts if need be to coax the air in.
