MCE Racing at Thunderhill Raceway Park in Willows California
Kevin Murray of MCE Racing has been tuning engines since 1966. Here is a long list of services that they currently offer at the Thunderhill Raceway Park: dynotuning two and all wheel drive, complete chassis set up, TIG Welding aluminum and steel, horsepower and torque verification for SCCA and NASA Spec classes, machine shop services, and emergency repairs for both cars and motorcycles.
When asked about a success story that sticks out in his mind the most, he replied, “I have always had this business at various racetracks. In the 2007 25 hours of Thunderhill, with 20 minutes left in the 25 hour race, I made a pair of titanium tie rods for an Augie Pabst prototype. They installed them with six minutes to go and ended up winning the race!”
