I have a built 2.0 and am running around 28 psi on e-85. When I hit boost I have noticed that it blows the antifreeze out the overflow. It is not overheating and there is no antifreeze in the oil. It is not burning any antifreeze either. I have arp headstuds and a Commetic metal head gasket all torqued down. Is the coolant cap pressure not high enough or what would be causing this?
