....I agree with you Guys. Boosting the pressure to the top end of a two stroke can
only be accopmplished by boosting the pressure to the crankcase. The problem is,
when the piston drops down far enough to allow the transfers to open, the exhaust
port is open as well. That would let all the extra pressure from the "supercharger"
to exit the exhaust port.

Keep in mind that the compression of the two stroke engine does not start until the
exhaust port closes....in any case. The system doesn't need help scavanging the
cylinder either....it already suffers from an aprox. 20% loss of the fresh fuel charge
as it is, in normal operation.

If one was to "supercharge" an engine....he would have to lower the compression
from the start. The two stroke is already a low compression engine. Raising the
compression above the normal level won't help, and in most cases is counter productive.

So like Motorboy has alluded to....a good pipe will extract more power than overheating
and overcompressing the engine.
