Bob Hoover is (was) a prolific writer and has forgotten more about VW engines then most people will ever know. That being said, being the VW guru does not mean you are the VW "God".
Some of the things he preaches as gospel have been proven at least exaggerated in practical application. The Sonex Turbo being able to keep itself cool is one good example....
A great read to get you thinkin... but don't be scared if your AeroVee does not employ all of his principals... (The prop is on the wrong end!.... or perhaps not)
