Generally, when a builder wants to put two engines in a car, they fuse the blocks together to make one big engine. A good example is the twin-Hayabusa V8 built by Hartley. The builder of this truck, though, has a much different method of getting the power of two engines under the hood.
, creators of this customized Dodge D-Series truck, managed to shoehorn two separate Cummins 6BT inline-six engines with new BorgWarner turbos into the engine bay, creating a 12-cylinder diesel-powered pickup. According to , power is sent to a Track Master 47RE four-speed auto via a custom gear case that connects the output of both engines into one shaft.
According to , cooling is done via a massive front-mounted intercooler with four electric fans and three bed-mounted icebox radiators. The custom frame uses a triangulated four-link rear end, air-bag suspension, and air brakes.
Plowboy Diesel uploaded a video of the truck on its maiden voyage, and it's just as cool as you imagine. Watch for yourself.
