Making power, No smoke in the exhaust, but coolant issues
I never had any of those symptoms and i also had a clean compression check. In fact the car made 733 WHP on a Dyno Dynamics with the bad headgasket lol
that was pushing water with an unsleeved block where the stock bore was actually shifting causing water to get pushed. not your issue.
reading through an old post and came across this, that describes my issue to a T. except i have a koyo rad and a new koy radiator cap that we just put in. Do i need a larger overflow maybe?
because it doesnt do it the first pull, usually the second or third after the overflow is already full.

Yea the tstat is opening and fans are coming on. And the temp is staying fine it hasn't been going over normal operating temps it just pukes out coolant after the overflow gets full, its good for 2 runs on the dyno before it fills and then it just pukes out. It goes back down though after it idles for a bit but during the process air is getting in somewhere

it does look like the HG or head is having an issue though. pressure bled it tonight and kept it below -20hg when i drove around the block and it still filled the overflow

Everything you wrote describes my head gasket failure. All of the pressure test were fine, no coolant in the oil still made lots of power but every time I got into the boost it pushed coolant.
Sad to say but I think you HG is done or if your sleeved it may have dropped a hair

I had a problem with coolant mate, I'm on the same turbos as you and I was boiling coolant when I shut the car off which was making air pockets in the coolant system. This caused me to puke coolant and over heat.
Car still made good power etc. I had to fit a new custom colant bleed system and I've not had any problems since then. Might not be your problems but get the car hot and shut it off and listen round the manifold turbo area for gurggling noise etc.
Hope you sort it.
