The Chaparral 2J,also known as the ‘fan car’, and also the ‘sucker car’, was the first of only a few race cars to feature fan-assisted aerodynamics. Built during the 70’s, the car was basically a giant racetrack vacuum-cleaner; a movable skirt underneath the car sealed in the vacuum created by two large fans mounted at the back (thus the name “fan car” and “sucker car”).
The 2J was powered by a chevy v8 that was tuned to push close to 700hp. The owner,Jim Hall, also decided to add a snow mobile engine behind the car. The two 17-inch diameter fans were powered by a single 45hp, JLO Rockwell snowmobile engine, which ran at constant speed.
