From No Brakes to the 200 MPH Club: Mike LeFevers


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.

    It was great to hear Mike. I go back to the days cruising/hanging out in front of the Starlight furniture store on Valley Blvd (Alhambra), – his garage on Dewey Ave. You should have him back for a Part II because there are a lot of “stories” from the early days yet to be told.
    Speaking as a fellow (but extremely less accomplished) “Gearhead” Mike has carried the banner for us “Shop Kids” from high school. Often looked down on because we weren’t “college material” Mike’s career and success excelled far beyond what our educators would have predicted. In addition to the sound technical advice he gave there was a lot of wisdom in what he had to say regarding life in general. And I think some of that was obvious when we befriended each other 45 years ago. Enjoyed the show. Proud of your accomplishments Mike. Tom

      Thank you Tom! It was great having Mike on the show telling a bit about himself. It’s definitely tough trying to cover someone’s life in only 90 minutes time but if he’s game, we’d love to have him on again to share more of his great stories and wealth of knowledge!
