I moved the engine mount forward 7" on my Starduster Too and made a new exhaust system. The new exhaust has more tubes further forward than the old exhaust so the oil cooler (mounted in the nosebowl) really heated up. So I moved the cooler back to the engine mount and put a 3" duct from the back side of the baffle. This works better but I still have rather high oil temps especially living in a hot California. I called Pacific Oil Coolers and they thought the cooler I had was a little small and I probably needed a 4" duct to it. So I am moving from a 7 row 1 pass cooler to a 11 row 2 pass cooler. The question is how to get a 4" duct running to it? There is no more room on the back baffle for a 4" flange so the thought is to try and hook up something from the cowl bottom. Where can one get a 4" NACA scoop ? Will this be effective ? If not any other ideas?
