i wonder if one were to bolt the intake to a flow bench, tape some yarn to the plenum, and watch what happens. maybe blocking off the runners you don't want to see ? or is that a common practice these days ? i have no idea how anyone does this stuff these days, so just bear with an old guy's blabbering.............
Flow is going from the carb pad to the head back and forth at a unbelievable rate. The yarn would flutter. Doug
