This is in an effort to keep subject matter where it belongs. If you want to see the engine discussion this came from, it is here: https://www.homebuiltairplanes.com/...ve-turbonormalizing-the-home-built-way.32083/

IF.... IF you wanted to increase the Vne on the CH 640 by Zenith, how would you do it?
Specifications and design limitations are listed here: http://www.zenair640.info/performances--specifications.html

RV-10 Vne - 230mph
CH640 Vne - 175mph

What aspects are different between the two that would result in such a large difference?

aaaaannnndddd.... GO.
