I'm really having trouble figuring out the math on this one. Let me explain. According to a few different posters, our stock lower intake flows between 200-215cfm per port when port matched to the heads. Now, that is definitely lower than some of the better heads out there, so I understand wanting to match the flow of the heads. But that still doesn't take into consideration the fact the best M90 out there flows less than 900cfm. Here's what I see...
200cfm * 6 ports = 1200cfm potential flow
- 900cfm blower output
------------------------------
300cfm of potential left on the table
Sure, opening up the lower may make things flow better, but we're talking about a positive displacement blower that can't outflow the parts we currently have. Now, an AR or M112 might be able to max this out, but it appears to me that our stock lower intake doesn't necessarily need more volume, only some modifications to better direct the air. Make sense, cause all this talk about how crappy our lower intake is (in regards to flow) sure doesn't make sense to me.
