A Cadillac CTS-V owner ripped out the factory supercharger and replaced it with a 106 millimeter turbo, roughly tripling the car’s horsepower and putting it into low 7-second quarter mile territory. This run was the setup’s maiden voyage, bugs and all, and the video does not hide that. Comments have zeroed in on the turbo’s jet-engine presence and the fact that the interior is still mostly intact despite the radical power increase. Watch the run and see what 1,600-plus horsepower looks like in a car that still has a back seat.
