Paul,

You are incorrect in what you say about forced induciton in regards to a Stocker. You would be correct if you could change the compression ratio or speed up the blower, but you can neither in a Stocker. On a cold (dense air day) more oxygen will always be ingested into the engine whether it is supercharged or not. A positive-displacement blower will only more "X" amount of air per revolution, so if you don't speed up the blower, you don't increase the air flow (to compensate) as you want to believe. On a hot day less oxygen makes it to the combustion chamber and we have to reduce the amount of fuel to maintain proper a/f ratio.
