I'm guessing two qts. max. We fill with ice as much as possible then just enough water to make the pump work. Crushed ice gets much colder but does not last as long. I don't know if we even have two quarts of water in. Either way several others have large ice chest in the trunk to put weight in the rear and have plenty of ice. I'm not sure how we should look at that since the weight is being added behind the main hoop but the system I have (same as Mitch had and several others) just will last a 25 minute race. I make Jay run the 40 minute race at Hallett and I'm sure there is no ice left after about 25-30 minutes. We have never tried block ice.....not really available at the track and would have to be made to fit the ice chest. I guess we could make our own but I'm guessing it would not be all that cold in a block.
