(it is to me :-)) Note the high temps before he added the vanes.

It seems that it straightens out the airflow so that it goes through the radiator more easily. I am seeing about a 10-15 degree F drop in coolant temperatures on hot days. I mean HOT days! When the OAT is 90 F outside, the coolant would go up to 220-230 F and there was not much I could do about it. Now it goes to 210-220 F and then drops to 180-190 F in cruise. This has been a problem engine from a cooling point of view, but now I think I have improved things a lot. It is the Eggenfellner conversion, with a Quinti hub and Warp blades. The blades consist of horizontal blades across the airbox in front of the radiator, extending from one side to the other, and from just in front of the radiator to the cowling opening. I now have three in each airbox. All are spaced to divide the air coming in the cowling. I should emphasize that this may not work in all engines, but it does seem to help mine. Chris L.
