Hi-Pro Shop and Racing History

In 1972 Jr. (George) Kaiser was employed by Harbert Casting Repair Service. The company specialized in repairing heavy duty & industrial engines. Jr. performed all of the machine work. In addition, he had a passion for drag racing as he had been racing Top Fuel since 1958. The racing and knowledge of high performance engines went hand and hand to help other racers with their engines and machine work. In 1986 Jr. incorporated Kaiser Enterprises Inc. Later the shop started doing business as HiPro Engines. The shop has always been a family affair, as both of Jr’s brothers Jerry and Tom worked for the company at one time. Jr’s son, Troy has been around the shop his entire life and also became interested in racing while helping his dad race.

After he graduated from high school in 1987, Troy became a full time employee of Kaiser Enterprises. In 1990 he became the crew chief of Jr’s car. He also increased his involvement by doing more and more work with high performance engines and the machine work for their Hi-Pro customers. In 1995 Jr. retired from racing, while in 1997 Troy began his drag racing career as a super comp driver. After racing super comp for a year he decided he would race in the Fast 16 class. Following five years in the Fast 16 class, Troy was able to get his A Fuel competition license through Randy Meyer racing out of Springhill, KS. He was lucky enough to race several races in the following two years in the A Fuel class. In 2002 Troy & his wife, Richelle, purchased Kaiser Enterprises DBA Hi-Pro Engines from his father. Today Troy has a great customer base and the work force to do any engine from high performance to heavy duty industrial.
