Yeah, if we ever took the time to figure out the actual cost per second under power on a drag car, it'd be downright scary!!!!! Back in the mid 80's we used to race one track on Friday night and Saturday, then load up, tow 250 miles, and race on Sunday.... This meant shutting the shop down around noon on Friday to get everything loaded up and gone, then Monday was spent unloading everything and of course a bit of time rehashing the weekend's activities with the guys so this meant working 12 to 16 hours a day on Tuesday thru Thursday to get all the work done so we could afford to do it again the next weekend!!!! It all seemed perfectly logical at the time!!! Same thing in the sprint car days, raced Friday, Saturday, and Sunday at three different tracks which involved 1200 miles towing every weekend!!!! It was a blast, but ain't no way I'd ever consider doing it again!!!!! Well, maybe twice a week if we had a sponsor picking up the bill!!!!
