This is probably a dumb question, but jus wondering what would happen if you cut the runners out COMPLETELY so air comes through the TB and BOOM into the heads basically. I don't plan on doing this ever but was jus wondering what would happen... really low vacuum?

 

Wouldn't run. Think about where injectors are, and without the air being pulled into chamber through runners, the fuel from injectors would not suck into chamber.

 

Ok yeh that makes perfect sense, thanks for pointin out the obvious for me buddy

 

Not a problem! I had to think about it for a few.

 

What you would end up with is EXTREMELY short runners..... There were pic's in another thread from a member that bought a manifold that had the inside of the runners completely removed. Would KILL bottom end, wouldn't idle worth crap, and zero power till way up there in the RPM range, and even then, it wouldn't be much.
