Seems I've read that you need more than 15in vacuum to have adequate pressure. The hydra-boost is one way; a small GM electric vacuum pump is another (80's - 90's Cadillacs used them).

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
