Do these engines love 60F temps?

I guess my thinking was at what point does the air get too cold to see a performance gain?
For instance do Rally Car racers see better engine performance in wintery conditions vs. cool weather.
Those guys really cover the calendar.

I'm sure there is a point were it gets to cold and performance suffers but for most of us that's never an issue. Were I notice bigger differences is with forced induction engines. The E55 AMG I had, which has a supercharged 5.5l motor, on hot 110 degree days would easily loses 50 to 75 hp and on cool 50 degree days have tear your face off levels of power. The Mini Cooper S I currently have also responds similarly with it 1.6l turbo motor easily lossing 10% of it power. More heat equals less power. Furtunately in the Boxster it's is not as dramatic.
