Wouldn't like to experiment, but as the turbo pump flows in the opposite
direction to the belt-driven pump I'd guess that there wouldn't be much
coolant circulation (if any).

BTW, when a head gasket blows coolant & oil don't always mix - it depends
when the gasket give way. I've blown a couple of gaskets in the past and
neither mixed oil & water.
