Josh, You might want to take a look at an airbox design article wriiten by Prof. Gordon Blair in the latest issue of Race Engine Technology. It certainly looks like more plenum volume is a good thing, although that particular engine was designed to run at very high speeds. In any case the...

I've seen where more than this, especially with a tight flat squish zone can lead to very high squish velocity which in turn can cause top land damage. This can be reduced by using a small taper in the...
