Peace at last among Indianapolis car racers.

The Championship Racing League will govern a 15-race series for the open-wheeled cars with directors from the once warring U.S. Auto Club (USAC) and Championship Auto Racing Teams (CART) groups.

For this year, the car specifications will vary from track to track depending on the club with which each track was affiliated. The major limit is on turbocharger boost.USAC allows only 48 inches on the popular eight-cylinder racing games while CART allows 60 inches. Next year the limit will be the same for all cars.

But Porsche and its Indy 500 car are still out in the cold. The German car is built for 54 inches of boost but the Indy 500 is under USAC rules. Unlike American cars, the Porsche cannot adjust its boost easily, so it may be packed for this year. Danny Ongais is to drive the machine.

Racers at Old Dominion Speedway in Manassas should save money under the track's new tire rule.Promoter Dick Gore has decreed that all stock cars at the track shall use either new Hoosters or Towel City retreads, which cost between $55 and $70 each compared to more than a $100 each for other racing rubber -- which lasts through fewer races, as well.

Gore figures his rule can cut the $8,000-a-year tire bill for top runners by 80 percent. Drivers testing the required tires at the 5/8-mile paved track report little difference in speed between the two.

The local weekly racing schedule for stock car races opens Friday nights at Potomac Speedway, a three-eights-mile dirt track at Budds Creek, Md. On Saturday nights, Old Dominion and Dorsey, Md., Speedway, a quarter-mile dirt track, are in action. Summit Point Raceway, the two-mile road course near Charles Town, W.Va., will have meets almost every weekend for either sports cars, karts or motorcycles.

Stirling Moss the uncrowned world road racing champion, has returned to serious auto racing, 18 years since retiring after a serious crash. Now 50, Moss is competing in the British Saloon (Sedan) Championship, driving on Audi, and in a series for historic single-seaters, piloting a Ferrari. He won his first start in the Ferrari but lasted only three laps in his first sedan outing. Moss has won 194 of 466 road races but never a world title.

Air India has set up the first Himalaya Rally covering more than 3,000 miles of open road racing through mountains up to 15,000 feet. It starts Oct. 16 in Bombay and ends a week later in New Delhi. The airline will airlift cars from all over the world to the event.

Desire Wilson became the first woman to win a Formula 1 race when she took the Brands Hatch, England, round of the Aurora Championship. wDriving a Grand Prix Wolf-Ford, she averaged 113.9 miles per hour for the 105-mile event, winning by 16 seconds over an all-male field.

American drivers competing in the winter "speed car" races in Australia and New Zealand report huge crowds but very small purses. Speed cars are American midget racers competing on one-fifth or quarter-mile tracks.

The Auckland, N.Z., track regularly draws 13,000 fans at $3 a ticket for its weekly shows. The purse is only $1,200 and winning the feature is worth $130. The Yanks are guaranteed starting money of about $700 per meet so any purse is gravy.

It worked better than chicken soup. A VW Golf (an overseas Rabbit) won a recent South African race running on cooking oil. It gives about 15 miles per gallon, burns cleanly, and smells nice, too.
