Just curious who is using coolant pressure to trim cylinder pressure?
It seems pretty common in the professional Subaru scene. (Prodive etc).
I like the idea of not lifting heads and replacing head gaskets. Love to know if anyone is monitoring coolant pressures and what sort of pressure changes are they seeing when the heads are lifting?
Thanks
Generally if you're seeing coolant pressure climb sharply then it's already too late as there is combustion pressure escaping into the water jacket (usually past the head gasket). It's normally used in high boost applications as a warning for the driver to lift off the throttle, or alternatively you could use it to shut down the ECU entirely for protection before something in the head gets torched.
