The custom VW Type 2 called “Oklahoma Willy” visited Santa Pod Raceway and went 10.623 sec at 154 mph. The unique vehicle was built by Perrywinkle Customs using a 1958 VW Transporter flatbed truck and a 1955 cc flat-four. Once it is ready to race the team fires up the Rolls-Royce 1986 Viper 535 Turbojet sitting on the back. The turbojet consumes 8.3 gallons of fuel per minute, spins at 13,760 rpm, and produces 3,450 lbs of thrust.

Building something like this is exactly how one should spend their time.
