MBRP Inc has built probably the fastest Colorado on earth. The truck was created for drifting with some road racing and drag added for fun. The LS7 motor was built by Dustin Portmess at Exotic Performance Plus. The motor had to be upgraded to handle the supercharger’s 22 lbs of boost. At that level the motor will produce an estimated 1,000 horsepower.
