IROC RSR, 910, 956 and Porsche Bug at the Historic Hillclimb Altbüron 2013

IROC History

In October 1973, twelve of the top drivers in the world were invited to participate in IROC, the International Race of Champions. They competed in a series of four races, in which all equipment was equalized. The drivers were from Formula One, USAC, NASCAR and the SCCA.

The car was the 1974 Porsche Carrera RSR 3-liter racecar. Fifteen identical cars were ordered by Porsche, with 318 horsepower RSR engine.

 This car was the spare car for the IROC 1973!

 

Here you can see the fantastic engine. Twin-spark, Bosch mechanical injection pump and the  special small Fan and the High Butterfly Throttlebodies.
