PORSCHE 911 GT3 CUP RS 997

In 2010, the American Le Mans Series (ALMS) implemented a new class for the full season, the GTC category. As a category comprised entirely of Porsche GT3 "Cup" cars, the class emphasizes strong competition among teams and drivers.

The car is a racing version of the Porsche 911 GT3 road car. As a car eligible in both ALMS and GRAND-AM competition with minor adjustments, this versatile machine can race at all of the world's great endurance events in North America, including the Rolex 24 at Daytona, the Sebring 12 Hours, and the Petit Le Mans. Weighing 2650lbs, the cars are made to fit a rigorous specification by both series, with the only adjustments allowed being ones that effect the car's handling and gearing.

The car is equipped with Brembo steel brakes. Central locking wheels are allowed in ALMS while 5 studs wheels are mandatory in Grand Am. Integrated air jacks allow for fast wheels swaps.

The 3.8 litre, naturally aspirated V6 engine delivers 480 HP and is coupled to a 6 speed sequential gearbox. 0 to 60 mph is obtained in less than 3 seconds and top speed exceeds 200 mph.

The data acquisition system from Motec provides precise measures of the dynamic characteristics of the car such as individual wheel speed, yaw, lateral, vertical and longitudinal gforces, shock movements, GPS position as well as many engine parameters. Real time transmission is not permitted, thus a lot of work goes into data analysis to fine tune the car in the paddock, particular in analyzing one driver's technique next to another.

The car is equipped with a radio communication system enabling two way driver / pit communications, which by series regulation must be transmitted on an open channel for the public.

Hi definition video recording provides exciting footage of the races from the driver's point of view as well as from the rear bumper. Videos are available on the download page of this site.
