Yikes, 250 WHp is going to be tough NA. I thought you meant 250 Hp (200 WHp).

I will get back to you after my first 9.5:1 and 24V ignition dyno run. I think I can get that (250 WHp) at 800 ft, I really doubt that I can get it at 4000 ft.

Still, I am convinced that the intake manifold is where the secret to rotary power lies.
I have a manifold Idea, but I don't have any good drawings of it on my computer.

I'll make you a deal. If I get 270+ WHp, I will send you all the intake measurements, Port cross-sectional area profiles and port templates used in my engine, then you can do the same (it uses all stock parts - slightly modified). Otherwise, I think that you are looking at a turbocharged car.

PP is not a bad option (although it will guzzle fuel). Really the PP and the turbo will have similar power bands and similar power levels. The fuel consumption will likely be comparable too. (The turbo is easier to do, the PP will run cooler and be lighter)
