I've watched a lot of guys on Pinks All Out who get into the finals and then run into a problem with their batteries getting too low to either crank the car or run the MSD box. They apparently are running their electric fans between rounds, trying to cool it down, and drain the battery.

I've always said that if I built a car for Pinks I would run a 4 D or 8 D battery (Diesel truck/marine stuff) and then have a second group 27 as a back up, on a selector switch. Lots of reserve amperage in those, and the weight could be helpful in the back for traction.
