I
I have heard of bracket racers going through a gallon and a half of fuel in one run. There is no way all that fuel is burning.
What type of fuel?
Quarter mile, I used a gallon a run. C12. That includes warming it up in the morning, driving it to the lanes and back, plus the run. Obviously less than a gallon to go A to B. Based on memory, maybe 3/4 of a gallon from the trailer, to the lanes, down the track and back to the trailer. Maybe.
Granted, I wasn't moving a huge amount of air, making big power or using a big carb,
