Tom,
The deviders also helped w/Turbo 6's carbed engine,so it's not just a multi port thing..
Now that you have installed your deviders,you may have helped the scavenging problem you have now a flow problem now & it's limiting your potential HP & torque,AKA ,,flow problem. It's just not as apparent w/the turbo stuffing the air in your cylinders.
The only way the deviders work (by flowing OK)is when you make the intake port so huge, it's not practical for a street car. I have done this about 20 years ago.
