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?

knonfs,
This is what the Excel program looks like.
send me a PM and with your email and I can send you a copy.
Most people don't understand the importance of an ideal mixture and it's to improvement to the burn rate.




Then on the second folder you take your corrected base map and check it any anomalies.
