Hello, I am wondering if anyone know the answer to this inquiry. When one lifts (or shuts off) the throttle on a professional Formula 1 race car does engine braking occur? For example, on motorcycles, with a two-stroke engine when one shuts off there is no engine braking at all. With a four-stroke there is engine braking (current technology is untilizing slipper clutches). The reason for my question is directly related to go carts. I saw the picture of Schumaker go carting on ice and was wondering how his cart compares to his car off throttle.
