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.

Why did you trade the 3100 for a 2700 or am I missing something.
