Motorcycle 'blipping'...

One of the justifications put forward for blipping the throttle on any racing engine, is that the open throttle imposes a load on the engine as it speeds up. This generates heat to hasten warm up.

The downside, that no one seems to mention, is that when the throttle is closed, and the engine is slowing, cooling is taking place, by the fat that the engine is running at high speed off load. In this case,the cylinder contents are being expanded, and adiabatically cooled. (The opposite effect of the hot end to a bicycle pump).
