From No Brakes to the 200 MPH Club: Mike LeFevers

September 14, 2018


The Gearheads sit down and talk engines, Bonneville records and more with famed racing engine builder and machinist Mike Lefevers of Mitech Racing Engines. He's  soft-spoken guy with some serious history. LeFevers was the Engine Development Director at Carroll Shelby Enterprises, spent five years in Gale Banks Engineering engine department, and was involved in the Buick Indianapolis program. He's not only the Treasurer of Save the Salt and Secretary of the Bonneville 200 MPH Club, he's also a life member of the latter.

He is the LeFevers part of the Kugel/LeFevers 1992 Firebird, which was the first production-bodied automobile to exceed and set a record over 300 mph in 1999. And it has power windows. Just like Mike, it's full of surprises.
