Efficiency ranges are different for rotary engines. We generally achieve the horsepower marks with lower psi ratings. That's why we all had 255 at 10psi while we're seeing cars like WRX's making only 225 at 14psi, and they don't have the restrictions that our stock manifolds and turbos have in them. Piston engines just boost much higher than rotaries. The compressed air flow has to stop and go a lot when it hits the heads. With no valves, that flow never really stops in rotaries. That's why moderately modded Supras run over 20psi and only the ridiculously mean RX-7's we know of are pushing it up that high.
