Zero clearance side seals round 2. (If you don't mind Barry)

This is for the guys building their own engines.

An engine built anywhere in the world will be capable of making approximately the same power if the builder uses good tolerances and has a close attention to detail.

This includes engines built by Jonathan, Carlos, Alex, Tom, Brian, Howard, Peter and you Ted....(if you don't see your name I can add it!)

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.
