Gutting the main cat is a no-no. I have a msds-y. Found a few things to correct and will dyno again soon...Like my KKM. With the 65mm tb and 75mm maf it is starting to implode. I took it off and drove down the street and my car went so lean it barely ran. And yes I just cleaned it. I'm going to a S&B big mouth I think and most likely 6inches. Feel fairly confident I will break 180 next time.
Isn't there a laminar flow problem with the larger MAF and Smaller TB??? Swirl/intake flow would be battered and become turbulent when forced into the smaller dimension of the TB. This may be wishful thinking, but subsonic flow is accelerated by smaller to larger openings ((eg. notice the supersonic afterburners of jets work with a compressed cone >....exst)). So a truly laminar intake, w/o ribbing in the tubes, would work best with a ramair setup and a laminar flow from a larger opening to a consistently smaller MAF, TB, and finally plenum. Hmmm.
-Whew
Overthinking Perhaps?
