I have plenty of exit for the air. The problem is that I am not getting the air to go THROUGH the oil cooler. My plan is to SUCK it through the air cooler.
What I want to know IS, what is the best angle to cut the pipes so I will get the greatest amount of suction. I need to FORCE the air to go through the cooler instead of taking the easy way out through the cylinder heads.

By making the lip stick down farther it causes more suction out of the cowling area.
