I am glad you asked. Folks, you don't get much past Boyd. The new oil cooler is about 1.5 to 2" taller than the old one. It is piggy backed on the radiator. Figured covering up more of the radiator would bring up the CHT, while lowering the eng oil temp. However, it may cancel itself out. Don't know yet. Have not test flown with the new cooler. Temps here are conducive to eng oil cooler testing. Yesterday was 94F and today is 92F. Main thing I was shooting for was bring down the eng oil temp so I could run hard in hotter OAT. May have to swing by Death Valley this trip to test it. ;-) john h mkIII ________________________________ Message 3 _____________________________________ Time: 05:30:12 PM PST US From: "John Hauck" Subject: Kolb-List: Tach Calibration Hi Gang: Did not take time to calibrate the old tach after installing the new 912ULS. Got her dialed in and flew to Lakeland and back. 18.0 hours on the new engine today. Did a tack calibration and was surprised that it was off by about 300 rpm. I thought I was turning 5,400 static, but was actually turning 5,700. Like flying with a 5 speed and cruising in 4th. We'll take care of that little problem tomorrow. Should be able to pull another 1.5 degrees of pitch into the prop. Ought to do wonders for my cruise speed and fuel burn. We shall see what happens during the flight West. Nothing sorts out an airplane and pilot than spending two, three, four weeks in the cockpit and flying a hundred hours or so. If there is something you want to find out about the system, you will find out on a cross country like that. Two days and counting, john h mkIII ________________________________ Message 4 _____________________________________ Time: 07:29:38 PM PST US From: "Doug Wetzel" Subject: RE: Kolb-List: oil cooler I think you'll find the Utah weather accommodating enough for you, John. It was 91 here in Salt Lake yesterday.
