I came across these power, torque, and fuel consumption charts from Mistral on the VAF. I have come to the conclusion that I don’t believe a word of it. Does anyone have any performance data that they would like to share that seems to make these charts seem remotely possible?

They are claiming 200 HP at about 62-6300 rpm with a NA engine.

I am thinking BS and apple butter. The apple butter is to make the BS tastier! :>)

I want to be wrong about this so I hope to get put in my place, but I aint holding my breath!

Here is a dyno sheet from a 12A rotary breathing through a 48IDF with 36MM chokes.

The object was best power at 9,500 so the runners are very short. Mistral had very long runners and fuel injection. And they spent more than a few years working the problem. I think they could do it all day long.
