On the 13b, I have a couple of questions:

1. How much HP can you get with a single Turbo? I'm looking for around
300 to get the performance I want for my wheeler.
2. What is the weight difference between a normally aspirated 20b and a
Turbo 13b?

When I look there are many more 13b engines available than 20b engines.
If a Turbo 13b will give me the performance I want, it seems to be
easier to locate cores for spares.

You can get 300 HP no problem but I am a bit uneasy about it for aircraft use. I would use a 3 rotor for the Wheeler if six cylinders aircraft engines are recommended? What is the gross weight?
