You can always build a higher comp ratio and plan to run less timing, I think timing more then boost leads to a more prone knocking FI motor, off course as rightly stated fueling makes all the difference, meth injection in various mixes, 104,110 octane fuel or the ultimate in street race gas, good ole corn E85.
Trouble with running real knock resistant fuel is you really need to keep an eye on your peak TRQ numbers as you can add and add timing beyond whats needed , increasing cyclinder pressures, motor still wont knock but the individual load is massive and will lead to a let go.
I love the higher comp, lower boost, moderate timing approach but with a good fuel set up, I think its a linear way to get a good power band.
That being said a 3K powerband that adds 150 WHP and 200 WTQ like a flip of a switch on a lower comp higher boosted motor is dam fun.

This and many threads lately have been very useful, its good to see so many guys open to share experience and knowledge.
