There should be no hero worship for anyone special. Forget the hype.

Your simple practice should be...
1- make the best possible sealing points... hence the zero-clearance side seals.
2- give the apex seals a flat surface to run-on using something like my sparkplug area cooling mod.
3- Make the AFR's spot-on with help from something like my free Excel AFR Corrections Program or any other autocorrect system.
4- And probably the toughest... center the combustion peak-pressure around 45 degrees atdc. This is where most people fall short... they go for what is called a safe ignition map.

If you follow these simple ideas you will have the highest horsepower possible at what ever boost you run, even NA.

Barry, what do you mean by #3?

Make sure its not too lean/rich under boost? all parts of the map?
