The Super Engine is used for speeding up karts during battles in Crash Team Racing, Crash Nitro Kart, and Crash Team Racing Nitro-Fueled. While active, the kart will have a constant turbo boost for as long as the player is accelerating, until the usage time runs out. The super engine's juiced up version lasts longer. In CNK, the icon's image had changed.
In Crash Team Racing Nitro-Fueled, the item will replace most Invincibility Masks during online races, if the player is below first place.
