Porsche campaigned a pair of Type 991 RSRs in the GT-Pro category of the FIA World Endurance Championship, and in a season of mixed results for Weissach-Flacht, the new RSR struggled to keep pace with Aston Martin and Ferrari, although Porsche claimed the one that truly matters to any manufacturer—wins of both GT classes at Le Mans.
Porsche Motorsport boss Hartmut Kristen took the time from a manic race schedule at the Circuit of the Americas to discuss the frustrations of making a new car go fast, and the return of a factory-backed U.S. team to compete in the 2014 Tudor United Sportscar Championship.
KM: Congratulations on coming back to the U.S. for 2014. The RSR down in the garage right now, in the WEC technical specification—is it the same car that CORE and Falken will be running?
Hartmut Kristen: More or less, yes. The current GT regulations used in both FIA WEC and IMSA GT racing have a freeze for newly homologated cars for two years, but within the first year you can do an update, and from then on you have to use that specification. In Bahrain you will see the final specification we will race in 2014 here in the U.S. And that’s this car with some slight modifications.
KM: Will you be allowed to make any major changes over the winter before Daytona or the start of the WEC in 2014?
HK: No. In this category you have the majority of parts homologated and therefore frozen. We are not allowed to change a homologated part without a request to the FIA, ACO or IMSA. Most of the parts that are free are not really performance relevant. This is also not where you usually can do the big steps.
KM: What about the aero package?
