im makin 900+ whp single turbo and even on lower boost pulls 650whp or so i was spraying coolant, only passenger side and it looked to be more soaked around cap, i changed the cap and now its mint, fixed... where is fluid under your hood?
Same place is yours. on passenger side wheel well, around cap, left side of hood ect
So, put a higher pressure cap on, add a bigger overflow and test it.
When I pushed water earlier this year, I reduced the boost, and dropped timing from 17 to 15 and made another pass.
It filled my overflow full.
So once the gasket begins to fail, they just don't fix themselves.
If it's not the gasket, you are golden.
FWIW, at 16 psi I was at 16 deg timing. Moving it to 17 after a baseline pass netted less than a half mph increase. I didn't see the point in going further.

Didn't realize you were running Eth. E85 doesn't carbon the ground strap like gasoline does but I would say those pictured have a good bit of white past the bend. Definitely warm.
You have to watch e85 in the cold temps especially if it was tuned at a warmer temp. I know sounds crazy but the latent heat value really cools the charge a bit, so combined it can push the chamber pressures a tad higher. Also, it vaporizes like crap when it's cold. Then when it gets really cold the Eth will break from the low octane fuel. That's bad, hmmmm Kay.
IAT timing needs to be reduced a few degrees vs 50+.

I buy it 75 gallons at a time and I get it from the pump. I test it every time I get it to make sure its consistent. This isnt the issue here.
