1963 Bobsy SR-2 Dietrich Championship Car



This Bobsy SR-2 is the works prototype car maintained by the factory to win the Championship driven by Chuck Dietrich.  Dietrich being a very accomplished competition driver and the Bobsy SR-2, proved to be a powerful combination during the 1963 season. Originally fitted with a Holbay-Ford 1100 cc engine mated to the faithful Hewland transaxle.  However, the cars design allowed engines from 1 to 2 liters to be fitted and race in lower or higher classes, only obtainable by its unique lightweight frame construction.

The Bobsy is dressed in its period livery of Black and Gold (Team Bobsy) wearing #88 as Chuck Dietrich did during his championship year with the car.  The car currently has a Loyning-built Kent Ford pushrod 1600 c.c. engine with 22 hours on it since the Loyning build and a head refresh completed in Sept. 2017.  The car produces 130 h.p. at the rear wheels with the ubiquitous Hewland 5 speed gearbox.


Produced by Gerald “Jerry” Mong in Medina Ohio, the 1963 Bobsy was successful against the Lola Mk.1’s in part due to its unique all aluminum tube frame with fiberglass body. Making them lighter than its competitors in the field. Powered by a Ford 105E 1100 cc engine mounted to a Hewland transaxle, the car competed and won the SCCA G-Modified National Championship. Mong continued producing the Bobsy in a couple different models through the years in kit form, all stemming from the very successful Bobsy Sports Racer 2 driven by Chuck Dietrich, the very car offered here.

The car is maintained to a high standard, and shows extremely well. It comes with a host of original Dietrich bits including the original seats, original aluminum suspension, and period Road & Track article about the car. The Bobsy has been maintained by the same shop the past 19 years, is very well sorted and competitive car in race-ready condition. The car in general is accepted nationally in many different vintage race organizations in North America.
