TnnrInr rn. Racing

It IS gratifying to note the interest that Is being taken in auto racing, as fully 40 per cent of the Inquiries which come through the columns have to do with someone seeking race dope or asking some question relative to building up q special racing job.
 There is very little comparison be- tween the ordinary touring cars abil- ity to develop speed and the manner In which the regular race cars attain their clements of whizzing through space Seasoned race drivers ire quently scoff at the local race jobs which are built for competition. still that spirit which prompts the speed boys to make their little speedster the fastest thing on four wheels in town is just what makes race drivers.

Although race cars boar the names of certain firms. they are rather the creative genii of some individual engineer and planner of the big factory rather than & simula- ton of the stock car. A mint of money must be put in a car to produce a winning racer. The Blitzen Benz cost Arnie Moross $35,000 to import for Bob Burman. My own mount in 1920 cost $21. 900 to build and we had s6, GOO worth of spare parts Millionaire" Johnnie Boiling Is known 10 have spent $l2b00 on his fleet Hudson. and the Richards special, which led the field last year at Los Angeles for 27 miles during the first 100 miles is said to have cost the owner $26,0 to build. Expensive material and costly labor run up the price of a race car.
