Fred Puhn built and raced this car, which is pictured as number
47 on the right and number 71
in the Road & Track photo above and on the right.
According to the 1970 Road & Track article, the Quasar
SR-70B had an aluminum semi-monocoque center section,
with sub-frames of square aluminum tubing front and rear. The sub-frames to held the suspension and the engine
and other necessary components. The whole frame weighed only 70 pounds.
The front uprights were Triumph Herald. Fred
specified small, lightweight hubs cast from magnesium, with aluminum Airheart brake calipers, and ten-inch aluminum
“monocoque” wheels of his own design and construction. The front springs were initially torsion bars, but he wrote that
many customers opted for coil over spring and shock combinations. At the rear,
Fred used cast uprights (believed to have
been magnesium), with Airheart brake calipers and 13-inch wheels.
The car uses a Sunbeam Imp 850cc engine and a Hewland 6
Fred found this car, purchased it back, and plans to
restore it for vintage racing.
