Bob Westphal's name is synonymous among the racing fraternity as "One of the Good Guys."

After building motors out of his garage for years, Bob got his break in 1969 working for Ed Pink Racing Engines in Van Nuys, California. Ed Pink specialized in Drag Racing engines. His clientele consisted of top names such as Don "The Snake" Prudhomme, Ed "The Ace" McCulloch, Tom "The Mongoose" McEwen, and Gene Snow, to name a few.

In the winter of 1978, Bob went to work for Raymond "Blue Max" Beadle. Raymond wanted everything done in-house. Bob was hired to oversee all machine work, as well as assemble the nitro burning hemi engines while the team was on the road. With this established, the "Blue Max" was NHRA Winston Funny Car Champion in 1979, 1980 and 1981.

During the 1982 racing season, Raymond announced the formation of the "Old Milwaukee Beer" racing team which consisted of Raymond driving the funny car, Tim Richmond driving the Nascar and Sammy Swindell driving the World of Outlaws Sprint Car. In addition to this announcement, it was also made known that Bob would build the sprint car engines in-house.

In May 1986, after many successful seasons with the sprint car team, including Sammy winning The Knoxville Nationals in 1983, Bob left Blue Max to open Wesmar with his partner, Dan Gentrup.

Dan is the other partner of Wesmar. Dan was a diesel mechanic in the mid 1970's who also had a passion for squeezing extra horsepower from an engine. While helping a friend on his alcohol-burning hemi engine used for Tractor Pulls, Dan came in contact with Bob at Blue Max. With Dan's attention to detail and mechanical prowess, Bob hired him to come to work at Blue Max in 1982.

Since the formation of Wesmar Racing Engines, they have built engines for a variety of racing sanctions. Wesmar Engines has competed successfully in Nascar Super Trucks, ARCA, ASA, NCRA Late Models, as well as Sprint Cars, All-Stars, ASCS, NHRA, WoO, and even a Bonneville Speed Car.
