The long trail of research had still another result, two years of piston research. Better pistons and better piston efficiency for better machines was the demand. Stock machine records fell to Indian during 1935. Castonguay and Langhorne and a sport scout clicked off 100 miles at better than 80 miles an hour; Chasteen, Kretz and a pair of sport scouts clipped off a bit of Castonguay’s time and tilted the record to 84 per hour, Rodenburg and Jacksonville accounted for still another win; Jesse James and a scout set a new high for stock machine performance at Daytona Beach and 101 miles per hour. From these tests came knowledge; they were the stiffest grinds that the mind of man could devise. Long distances, grueling competition, abnormal conditions. From the combined results of these came piston knowledge from actual test-the test of the road. The laboratory had furnished their part of the story with unleashed engines running almost free from load at impossible revolutions per minute, from chugging engines, bitterly loaded and deliberately robbed of proper cooling. Now it was the road that took up the job. The laboratory had told what they would stand in heat by devious methods deliberately by created heat; the road now told what they would stand in the way of abuse, heavy running in dust-choked competition, under sustained load, under the severe jamming force of abrupt “buttoning” at high speed.
