The Tudor USCAR Championship brings the PC (formerly LMPC) class cars from the American Le Mans Series. These ORECA Courage FLM09 prototypes, which Katech builds, maintains, and supports the engine for every single team in the class. These race cars feature a full carbon fiber chassis, carbon brakes and an Xtrac sequential gearbox with paddle shifting. These high performance race cars weigh in at a mere 900 kilograms and can reach speeds up to 170 mph.
The PC prototype chassis is built by French manufacturer Oreca and known as the FLM09. Oreca tried to keep the car relatively simple, in order to cut costs. Chassis tuning can be accomplished by; changing the springs, anti-sway bars, bump and rebound adjustments, camber, toe, ride height and tire pressure adjustments.
The LeMans Prototype Challenge class debuted in 2010, most LMP-C cars are driven by two drivers in the sprint (three-hours or less) races and three drivers in the longer events. The driver line-up usually consists of one professional and one amateur driver per car in the shorter races and one professional and two amateur drivers in the endurance races. It was an extremely close championship throughout the 2011 season. Team Core Autosport took the 2011 LMPC team championship. The team championship came down to one point over Genoa Racing, quite the accomplishment considering that 2011 was Cores’ first year racing in the LMPC series. The drivers’ championship was settled with a tie between Core Autosport drivers Gunnar Jeannette, Ricardo Gonzales and Genoa Racing driver Eric Lux. This is the first time in ALMS 13-year history that such a tie exists and can not be broken.
The PC race cars use Chevrolet’s naturally aspirated V8 6.2L LS3 engine, the very same engine that powers the Chevrolet Corvette and Camaro. While keeping some of the stock LS3 components, such as the block and cylinder heads and drawing from our experience of racing and success with the Corvette GT1 cars and the Camaro GT.R, Katech prepares and builds each engine specifically for the PC teams. An oiling system upgrade is a must with the PC chassis and the engine receives a dry sump system to combat high G-forces and high down force produced from the PC race cars. Custom camshaft and Magneti Marelli engine management system are used to optimize running with a restrictor per IMSA regulations, along with high-strength rod bolts, custom forged pistons, racing bearings, and our proprietary hot-hone process, which are employed to ensure perfect reliability and performance under sustained high RPM and load operation of these professional racing engines. Continuing the success from 2011, Katech is proud to be the exclusive PC engine supplier again for 2012.
2012 marks the 14th season for the ALMS. The series offers a mix of the world’s most premier and leading teams and manufacturers. These races are held on North America’s most prominent permanent road courses and urban street circuits. The ALMS is sanctioned by the International Motor Sports Association, better known as the IMSA and is in close association with the ACO who organizes the famous 24 hours of LeMans.
