No need to lose efficieny. It is the other way around. More efficiency 
with the injectors on the opposite side of the exhaust. Check that picture 
of the Mecanair engine again. Racing Beat confirms what Mecanair found 
on their dyno. Throttle response suffers. The dyno show better BSFC
with the injectors on the intake end of the long tuned runners.
