Can a normally aspirated engine consume more more air than it's actual cubic inch? These are just a few questions we need to ponder.

Let's start with the induction cycle. Ask questions even if you think they stupid. In my opinion there are no stupid questions. Some of us may be at different knowledge and skill levels than others and that's okay. My objective is to educate everyone and someone out of left field may have an idea that no one else has thought of yet. Our brains are amazing computers and if challenged will find a solution. Some times it just takes a different perspective.

Good post Don. Its always a challenge to find a way to fill the cylinder better. Unfortunately the truth is the guys who are finding ways to do it really dont want to share either due to hard fought lessons and info or ridicule from self professed genius know it alls that have only read a website or copied what they think someone else did. Then claim its just physics as if fact and never learn a damn thing.

Its sad but the public gets drug into beleiving the crap as if fact and waste money. A fella can make a lot more power than they think with good parts and a good plan.

For instance hows a small 400 cfm head make 1175 hp at 8500 rpm on a 564? Everybody thinks they know yet there's almost no one doing it.
