Morphology

hot + up

The particle 'up' signals increase and 'hot' conveys higher intensity, so a learner could infer a general sense of making something more powerful or intense. However, the specific mechanical sense of tuning or modifying parts to improve an engine is metaphorical/specialized (and could be confused with 'heat up'), so the meaning is only partly predictable from the constituents.

Etymology

Hot up comes from the simple picture of something getting warmer, like a room or an oven getting hotter as the heat builds. So it means 'to become hot'.
