air to air for race applications, chargecooling (water/air) is great as a 'packaging solution' for road cars or stop/start, low speed vehicles, but given the extra weight of the additional rad(s) waterpump, not forgetting the water itself, its difficult to justify in a racer.
the other worry, although very unlikley, is if the charge cooler fractures internally, the water leaking into the inlet will hydraulic the motor with disasterous results!
