San Francisco builder Jacques Andres wanted to build a competitive Mini for the 25 Hours of Thunderhill. He didn’t have the money to build a 500 horsepower engine so he decided to just install another motor. Each engine is a factory supercharged 1.6L four-cylinder good for 250 horsepower. With both engines the Mini weighs 2,700 lbs. Jay Leno seemed to really enjoy the car. I think he should pay Andres to build him a street legal version.
