Would it be possible to combine the p port and turbo?  Since it never
comes up, there must be some good reason for not doing it.   Jerry

Only if you want over 400 HP per rotor.

Hi Paul

We recently had to strip our blown alcohol 20B down due to a blower backfire
shearing the eccentric shaft keys again (even though we double keyed it 180
apart). I am purchasing a billet eccentric shaft new from New Zealand, as
ours was damaged. The billet shafts are harder, straighter and lighter than
stock, for about $2,000AUS.

We are going to PP the engine whilst we have it apart, to get more power.
Using 52mm round ports, in a position to give power from 4500 to 9000. One
injector as close to the housing as possible on each runner, then one about
6 inches back, then injectors in the hat above the blower (this is
mechanical constant flow injection) and different pressure check valves
bringing in each set at different revs. The butterflies are in the hat at
the top. Each runner will be 55mm ID at about 18 inches long to the plenum.

Any comments or advice would be appreciated.
