Justin, Steve, I guess this is just a reminder that we need to baffle up the VW very well otherwise you have oil temp and cyl head temp problems like I have.
I had a Baffle system which was obviously to leaky. Oil was ok cyl head was only good if the outside temp was below -2°C. Anything higher meant an increase climb speed to keep the cyl head temp under control. I changed in April to a fiberglass plenum like it was described in one of the KR newsletters. Somehow my plenum did not do what good plenums do, and now, in the middle of summer, I have hot oil and hot cyl heads. Currently I am not flight testing because the last 20 flight have been cut short because of temp problems. I was going to install a remote oil cooler, but a friend and Steve have convinced me "again" to go back to the baffles, seal them really tight and try again, before investing any money in a remote oil cooler. I personally think Steve (GPAS) is a super guy. Thanks for your help. So on Saturday I will install the old baffles again and try to get the extra seal and try again.... One thing I observed is, that the pressure on the top of the engine cowl is so low, that air is actually sucked out of the top of the cowl, if you have any openings there.
