Hysteric,
[1] Vizard was an engineer first [ Aero Space ], magazine writer second. At least give the man credit where credit is due. I wouldn't call his 520+ page A engines book a 'magazine'.....
Sorry but changing parts and playing with a dyno doesn't qualify as scientific research in my view. I have a book by him on carbs and intake I now wouldn't bother referring to.
If I wanted a deeper understanding of how this stuff actually works I wouldn't go to vizard for any of that.
If you think Vizard is the pinnicale of engine building you need to get out more.
