Heres an example of what a weather change will do to a high performance engine. If the temperature is in the low 80`s my 10 second dragboat will run in the middle 9.90`s. On a 90 degree and above day the time will increase to sometimes 10.15 seconds. Saturday is usually qualifying and Sunday is win the round or go home. I try to conpensate for this by advancing and retarding the timing by about 2 degrees.
