Here is the bottom line though I know you already said you don't want to hear thermo theory about how engines work.

The two primary factors that control power output in a motor are actual compression ratio (boost+compression) and the mass/sec of fuel/air the engine can process.

Since the turbo is creating compression and increasing the mass/sec the engine can process by using energy that is normally lost in the exhaust gasses that is something you want to maximize through the highest possible boost.

Regular piston compression is stealing valuable crank power and limits the amount of boost you can run.

Before you go against this by thinking that you can run high compression and high boost by running pig rich, don't forget that you sacrafice the available power you can get from each gram of fuel/air the engine processes by doing so. The math could easily work out that whatever advantage you gain from increased boost is defeated by the power losses from a super rich mix.

For this reason the best combo for max power is low piston compression and high boost.

Intercooling, plumbing efficiency and good tuning is all about pushing the envelope of these basic principles.

The only downside of this combo is that your power output sucks until you hit boost, and this is the only reason for going against the low compression / high boost combo.

Its the only reason I want to bump the compression in my car from 7:1 up to about 7.5:1.

These are solid scientific facts that you can verify by looking at every high output turbo motor that is built to reliably to run on pump gas.

Reading a book on the subject of thermodynamics could also do wonders for you too.
