Hoyt When you reach that point (Making Holes bigger) you just figure out a way to flow more air then you make the holes bigger and go still faster. In my above post I was making fun of a guy that proved something beyond a shadow of a doubt that was wrong about a month later. One thing all these years of playing with engines has showed me is nothing is ever as good as it can get because tomorrow someone will make it better by doing something that just couldn't work but did. Like a wise old aircraft engineer told me once " you can make a 2x4 fly if you put enough thrust on it".
Been there, Done that, Hope to live long enough to do it again.
