My buddy stepped up from hot farm stock to hot farm a year and a half ago with his D-21 Allis. He now turns considerably more RPMs and it seems that every time he hooks,the cooling system pushes a little coolant from the start line, then after a little way down the track it turns into a geyser. His somewhat mechanic keeps re-soldering the neck onto the top of the radiator. I believe that the higher RPMs are causing the system to over-pressurize more than the cap can release, and he needs to either put a smaller pulley on the pump or put an electric pump on it. Any body have experience with this?
