Sorry... I am thick..... I see why Oval port is the way to go. But I can't get a grip on the Open or Closed Chamber or the CC amounts, and which way to go and why... DId you explain and I am too thick to understand?

Now we are gonna get into the meat of this conversation. Couple of differences here when we speak of compression ratio. There are static, and dynamic ratios.
