Show tires resulting from traveling-counter traveling-counter clockwise on a 12-mile circular course which is used in tries for high average speed. A section will be inserted in the body behind the cockpit to make room for the extra engine in the straightaway job. "I hold all 'but five of the land records and I'm going after them with the best racer ever constructed," construct-ed," said the gray-haired retired building contractor. Ab said he expects to make 370 m.p.h. in the single-motored car which was built by A. S. "Augie" Dusenberg, noted automobile engineer. en-gineer. "The Englishman's Thunderbolt weighs about six and one-half tons." Jenkins said, "while my car weighs only three and a half. His car has a wind resistance area of between 30 and 32 square feet. Mine has between 21 and 23. "Eyston's engines develop more horsepower but mine have less weight to push. He has 3,400 horsepower. I have 2,400. "The ratios of weight and wind resistance to horsepower give me a wide edge." i UTAHN PLANS SPEED RUN BY MID-SEPTEMBER INDIANAPOLIS, Aug. 30 KP Ab Jenkins of Salt Lake City is building a racing automobile capable of 375 to 400 miles an hour with which he hopes to return re-turn the world speed record to the United States, it was learned today. Jenkins, working with a crew of seven mechanics in a small In-dianopolis In-dianopolis machine shop, said the car probably would oe ready for a run over the Bonneville salt flats by mid-September. The record, held by Englishmen for nearly a decade, was raised to 345.49 m.p.h. last Saturday by Capt. George E. T. Eyston of London. Lon-don. John Cobb, a London fur broker, is preparing to challenge that mark. " Englishmen Supreme The last American to hold the land speed mark was the late Ray Keech who made 207.552 m.p.h. at Dayton a Beach, Fla., in 1928. i The late Major H. O. D. Segrave of England pushed it up to 231.-362 231.-362 in 1929 and since then it has been pushed higher and higher by his countrymen, Sir Malcolm Campbell and Capt. Eyston. Jenkins and his mechanics are now riveting the final streamlined stream-lined plates on his giant racer which will be powered by special Curtiss-Wright motors. "First I want to break all the distance speed records up to and including the 24-hour run," Jenkins Jenk-ins said. "Then I'll switch the hull of the racer onto a longer frame, add another super-charged engine en-gine and shoot for 400 an hour." Only One Engine The present machine has only one engine and the frame was constructed off-balance to counteract count-eract the pressure on the right |
