glycol actually lowers the boiling point of water, and has less heat transfer capabilities than std water.
also because it is more viscous it is more prone to hot spotting, and put more load on you water pump.
IMO youd be better off running std water in a turbo car than coolant.
def agree with your comment about the cold tho.
if i knew there was any posibility of it freezing over night i would still run glycol.
