i was wondering how much of a difference there is between a 60 degree day vs. a 80 degree day with high humidity. so in other words, how much time in tenths will i lose at a track in the 1/4 mile on the hotter day compared to the colder day??? the car is all stock with bolt-ons if that matters.

 

My guess would be around 3-4mph from 60 degree no humidity to 90 degree high humidity, just a rough estimate.
