The Shadow DN2 was a series of racecar built in 1972. The cars came with a naturally aspirated or a turbocharged Chevrolet engine.
Powered by a 494 cubic inch Chevrolet engine fitted with twin Schweitzer turbos and fed by a high-volume Bendix fuel system, the cars were driven by Oliver at Road America and by Elford at Laguna Seca and Riverside. Don Nichols retired the cars after the 1973 season.
Lee Muir was in charge of engine development and prepared a turbocharged version of the Chevrolet big-block engine with specialists George Bignotti and Danny Jones. They claimed 800 bhp and 985 lbs/ft torque at 5,000rpm. It debuted at the 1973 CanAm series.
For the bulk of the season, Jackie Oliver piloted a non-turbocharged car and it was unreliable at the season opener at Mosport, Road Atlanta and Watkins Glen. At Mid-Ohio, the DN2 placed second overall and its the closest Shadow Racing came to victory that year.
