Yeah you would need a car-oriented transmission and gears for a car application, but I was only talking about the engine.
Engine braking is far less load on the engine compared to full power. It's just compressing air from 0 to 140 psi, far less than combustion psi. You simply won't slow down as fast with more mass / more inertia.
