Hi JB, Our Savannah VG 2010 build has been running with no oil cooler (Jab 2200) since build, no problems with overheating, however, last Thursday, 19 04 2018, 27 degrees and the hottest day for a long time, after a 1 1/2 hour flight the oil temp was up and pressure dropped to 2 bars, normal pressure for our one is around the 3 and a bit bars, at 2400 rpm, I have the oil cooler kit and am thinking of fitting it next service, I looked at your pcs on media, did you sort it ? Thanks Dave.
