This Chevy Colorado was built by The Diesel Shop out of Miami, Florida. Under the hood they installed a long-block 6.6 L Duramax diesel V8 with the accompanying Allison six-speed automatic transmission. The engine runs a Garret GTX4202R turbocharger at 42 psi of boost and bigger injectors which help produce 660 horsepower and 1,125 ft-lb of torque. One of the videos below show it doing the quarter-mile in 10.5 seconds at 134 mph.
