If you cut the tubes even with the cowling surface, I would think the air passing over the cowling and tube ends will create a vacumn on the tubes. Someone correct me if I am wrong but I think machinest parts hold down vacumns are 90 degree orifice. Larry H.

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.

Heath - Lexington, SC -------Original Message------- You can also increase the size of the lip on the bottom of the cowl to increase airflow OUT of the cowling. By making the lip stick down farther it causes more suction out of the cowling area. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to [email protected] please see other KRnet info at http://www.krnet.org/info.html
