Do you mean that you are going fast with a cold engine? If so, that is a very bad idea. How fast are we talkin'?
Your engine oil needs a chance to warm up so it can flow through your engine and provide a hydraulic wedge between moving metal parts. When oil is cold it acts like cold syrup. It clings to metal parts instead of flowing. This clinging slows down the power output of the engine until the oil warms up. That is why all race cars warm up the oil before they even turn over the engine.
Your engine may also have a oil flow sensor that controls the power output based on the oil temperature.
