KR> VW engine oil temperature
You guys can use aviation grade parts as well. ?Positech Oil coolers available through Aircraft Spruce are a good buy. ?$165 will get you a good aviation quality oil cooler that will address high oil temp issues. ?I installed one of the Positech coolers on my SuperCub clone. ?I make a lot more heat and have a lot less air flow to work with, but it keeps the oil temps on my O-320 nice and cool. ?I would think the oil cooler intended for either the O-200 or a Rotax would work quite well on a VW. -Jeff Scott Los Alamos, NM

Here is a link to the Mocal cooler that I am using.

If operating from 2100 foot strip, you will want a drag device for approach, either a speed brake or drag producing flaps. You might want to remove as many trees as possible for takeoff as well as landing. Larry Flesner

KR> VW engine oil temperature
Sid, I used the fins on the bottom of the case to help cool the oil. Not sure how much it helps. IMHO, full flowing the oil and a quality oil cooler are the most important factors. I tried numerous things early in my flight testing period to keep the oil cool but changing to full flow and a Mocal 13 row cooler (from one of those stamped pieces of crap) took my oil from 250F to 190F. Oil temps are the nearly the same if I am in a climb, cruising to a destination or full throttle for 2 hours during a race. I am currently reworking my entire cooling system and will not flow air across the bottom of the case. I don't feel that its worth the effort.
