Gearing question

So, how much does the car weigh...No, we don't really have any cooling issues unless we don't have time to cool it between rounds...CSR Aluminum elec. water pump and alum. radiator (can't remeber what brand, I believe grant), 1 elec. fan... Usually on a hot day and not getting cooled good it doesn't get over 200...Usually with cooling, by the time we get back to the trailer, it is around 180...Lee
