I have had experiences where I want bottom end motors so ran 4 hole gaskets seperating dual plane intakes and they ran like cr__! Went to open gasket and they ran fine. That mostly happened with like Wei____'_ dual plane intakes but not only them. I was wondering about dual plane with N20 and wanting to try like 2" 4 hole spacer seperating both sides of the intake. My thoughts are a little machine work to blend the two holes on the one side of the intake so you could install a fogger nozzel on each side so I could push the button at 1000RPM and have incredable torque! 8) I want max torque idle to 3000 RPM so I am thinking isolated planes would be better than installing an open plate with a spray bar but I have never tried it! :lol: What do you think!! 8)
