I do have the LoPresti cowl (both were installed when I bought the plane last year). For me, the hottest cylinder is the #4, which can climb into the low 400's on climbout on warm days. The highest I've seen it though is about 420. Others rarely touch 400. In cruise I generally see about 350-380 on the cylinder temps on warm days, and a little cooler on the cooler days, but not a huge variation. I have been having a couple problems though, and thought I'd get your input/thoughts: 1) The #1 CHT has been working fine until a couple months ago, when it started acting up: specifically it works for about the first 20 min of flight, and then dies. On my way to Baraboo I had the probe replaced, but it is still doing the same thing. The guys at JPI tell me it could likely be the installation of the probe - specifically the crimping, which has to be very snug. I remember the mechanic mentioning this when he replaced the probe, so I assume he would have done as good a job as any.....other thoughts? 2) Yesteday I noticed that my fuel flow indication is suddenly about half of what it should be! Now either I have the most efficient Tiger on the planet, burning 5 gph in cruise, or I got a problem.... I'm guessing the transducer is toast - other ideas? Assuming the transducer needs replacement, here's another dscision: my plane has both a Shadin Miniflo and the JPI 800. Which brand transducer do I get? Has anyone else had problems with transducers crapping out?

Now, after a LoPresti nose bowl and a Gary baffle replacement, (and some training on correct leaning procedures for climbs out of Red Bluff or Trinity Center in mid summer: T>30 C), I have seen 450 momentarily, twice, in climbs. Corrrected by lowering the nose to about 300 fpm, and richening one click. Cruise is always below 400 on all four cylinders, using 2650 rpm and the JPI leanfind at 5500 to 11500 (I've checked the tach and its within 50). Christine is flying OK. ________________________________ Message 3 _____________________________________ Time: 10:21:46 AM PST US From: TeamGrumman@AOL.COM Subject: Re: TeamGrumman-List: Engine analyzers --> TeamGrumman-List message posted by: TeamGrumman@aol.com In a message dated 8/9/04 3:33:46 PM, awilliams2@carolina.rr.com writes: > I have the EDM-700 installed and can report similar results.

Then, cut back the baffle strap that wraps around the bottom of #4. I usually take off an inch, keeping the 45 degree cut.

First, get the gizmo that JPI has for checking the operation of the JPI 700/800 itself. We found the JPI 700 had failed.

Take you plane to Lincoln and have them strip and repaint sections. It'll cost a little more but you'll be happier with the results. ________________________________ Message 7 _____________________________________ Time: 11:08:28 AM PST US From: Anna3003@AOL.COM Subject: Re: TeamGrumman-List: Paint --> TeamGrumman-List message posted by: Anna3003@aol.com I just saw a Mooney in Palo Alto with a paint job from the Lincoln place.

Over the first part of the summer, I made (or assisted in making) new tooling (molds) for the cowling. I had made a number of changes to the cowling, found some things I wanted moved and wanted to start out with fresh tooling. I thought the first parts out of the molds would be ready to go. It doesn't work that way. Because of the changes made, the parts were very difficult to remove from the tooling. I had gone from 4 pieces to two for the major cowling sections. I found that all of the mods done to the original prototype had made the cowling very stiff. Felt more rigid if you will. Hell, it weighed 32 pounds. The new one was an extra ply of fiberglass and vacuum bagged. It only weighed 14 pounds total (no hardware). However, the sides were very flimsy. To me anyway. At Baraboo, I noticed the new AG5B carbon fiber cowling is flimsy on the sides too; but, not quite as flimsy as mine. I had removed all of the doublers in the upper cowling because the shape makes up for stiffening. However, the rear portion of the upper cowling needs some stiffeners. Plus, we had some trouble with the overlap on the right side. Those joggles aren't as easy to make as you might think. As it stands right now, we're looking for some 1/8 inch foam for stiffeners and doublers. The local distributor is not being very helpful. We're also going to make a fairing for the nose strut; something that could replace the rubber one on the stock cowling. As for cost, in fiberglass, as it stands right now, the cost would be in the $6000-$8000 range. In carbon, add about $500-$1000. I need to add pressure taps to my plane for measuring pressure drop in the cowling. Plus, I need to find a way to get temps on #3 down to something reasonable.

This is a PowerFlow I installed a couple of years ago. While I was removing the muffler section, I noticed that the 1/4" bolt through the big clamp (that goes around the muffler) was worn nearly all the way through. The instructions suggest that the bolt not be tightened. If it's not tight, however, it moves on the support strut attached to the engine mount. **** just a thought, if you have the PowerFlow, check the bolt for wear. Also, the slip joint (between the muffler and the S-Bend pipe): The muffler portion is being swedged out due to vibration. Plus, the locating dowel on the clamp which holds the muffler to the S-Bend is also walloring out the hole in the S-Bend. It's a nice simple joint, I just don't think it's made or designed very well. A ball joint on the muffler-to S-Bend and the rest being welded would have been a better solution.
