Marine engines are crazy. This engine was built by a company called Boostpower USA Marine, and it is quite a motor to say the least. It’s based on a 645ci Chevy big block V8, and has, among other things, two turbochargers feeding two superchargers, making as much as 40 psi. Depending on the fuel and tune, it makes between 985 and 2,400 horsepower. And it’s designed to do so reliably for long periods of time at sea. I wonder if it would fit in a Miata...
