Paul,
I agree, the 993 have shorter primary lengths which equates to a lower energy loss. The larger primary size lowers gas velocity at lower RPM's. The two probably cancel each other out when comparing to the SSI setup. So it's probably a wash there.
Trying to remember my days of studying thermodynamics...... When there's a loss of gas velocity, heat energy goes up or down? I think it's a direct relationship, so energy should go down.
