Turned twice as fast one way as the other. Those kites could do 6 g's in a turn. The spinning engine provided 90% or the valve spring tension dueto centrifugal force and the Le Rhone with intake runners was also a centrifugal supercharger. I think it was 80 HP at 1200 RPM and weighed around 325 to 250 pounds. Took something like 80 man hours on a lathe to machine each cylinder jug. 100 pounds of steel finished to something like 7 pounds and a lot of cuttings on the floor!
