I think it’s also used to refer to revving up one’s motorcycle

Specifically a hog is a Harley (or really any touring bike now), large, slow turning, and they start with H, and yeah you could call racing the engine (the vroom vroom throttle thing) cranking, though that’s more of an action on older motorcycles you’d do to actually start the thing

The term from male masturbation actually comes from crank-start engines
