Higher Meth % would be required with higher boost and more advanced timing.

Presumably, you need to log and see if there are any knocks, if so, higher Meth % would be required.

Some run 100% because they need to (boost levels) and others do it at lower boost, just for the insurance factor.

I intend to start at 50/50 and log. Will go up to 100% or whatever is required to ensure 0.0 knock at 17 PSI. (this is simply my target)


Uneducated Comment: I believe water would have a better cooling impact, though Meth would certainly help too. I'll be testing this for myself soon enough.
