Tom,

What engine/PSRU are you planning to put in your Venture?  It seems to
me that you are going to have to do some thinking about this combination
if you plan to use a Mazda engine.

Thanks for your info. I did contact Craig Catto and here is his response:

Hello Tom,

That is going to be quite a challenge to fit.   We make them for the 540
Berkut, and that is about a 285mph aircraft and have done one for a
E-racer turbo 540 at 350HP doing over 300mph.

I do not think I want to challenge the auto conversion, just the power
curve many times seems hard to fit. We know the curve of the Lyc engine
very well and so not such a big deal to fit in these types of
applications.  Easiest way for you to fit it is probably with a MT.

All the best,

Craig

 

I was surprised at his answer as i thought he did Tracy's prop. The
speed of the Venture will not be that much more then what he described.
It may be the high HP I will be using.Any more suggestions would be
appreciated.
