Back decades ago I used to go to the local dragstrips and hear the cars a lot...up in the Wash DC region of Md.......
when moving to Floriduh, I found out about Gainsville being just down the road an hour or less.....so went to one of the national runs......
ONE of the cars is loud as hell......the combo of two taking off at once gets the engines slightly out of synch with each other.....and the extreme pulses get additive and subtractive at the starting line, and that air pressure is really felt in the chest.....as I was right at the starting line, pretty close to the fence......
