sorry to hear this mark.

a warning light sounds like a good idea, but couldn't something also be done in the ecu? for example, there is a modifier for the ignition based on coolant temp. couldn't that be used so that when coolant temp is higher than normal limits, ignition advance is changed to drastically reduce the power available? that would have the 2 fold effect that you feel it when driving, and if the power produced is less, less heat will be produced.

don't know if that's a good idea, maybe worth talking through with stu? at least a loss of power could allow you to limp to the end of the stage without suffering major damage.
