Kind of hard to make a general rule for this. 11.0:1 is fine for fuel. But for timing, it is more tricky. If you are too advanced, your egt's get high even without knock. If this is the case, then yes, you want to retard it. But if you retard too much, you are right. Things will get hot.

The easiest way to control temps tho is to just turbo down the boost...

the 3 row pwr steering cooler is a piece of crap. Take the 30 mins and $25 bucks to replace it with a small B&M cooler. If you are any where near fast, you will boil it. Take some extra fluid with you just in case.

Also, flush your radiator and run a bottle of water wetter and water. It will help.
