This 64E has a dog house, and the mod came with left and right mods that attach to the cowl. The left provides air for heater, the right proves cooling to an accessory, in this case, the alternator. I have a "plane&power alternator, which has an air inlet for cooling. I will add that the mod has the option of placing shims between the starter gear and the bulkhead. This moves the spinner forward. In my case, if the shims would have been required, I may not have continued. This is because of the effort required to change the prop bolts.

The cost of the ari mod was 1500.00. I had to locate my own 201 2 blade spinner, as I have a McCauley prop(214), and they are not available any more from mooney. Paid 400.00 for spinner and bulkhead assembly. Logged about 15 hours on the install, which included removal of a Lasar lower cowl closer. I had removed the prop and H1 governor for rebuild . The old H1 governor was not serviceable , so we installed a PCU5000.

Thanks for all the great comments...although this paint is 20 years old, frequent polishing and hangar life is helping to prolong its life. I really wanted this mod, as I wanted to retain the avionics access panels. Prior to this cowl mod install, just completed STEC 40 to 50 upgrade, and GDL88 install. Time to fly!

Just wanted to provide an update on the installation of the ARI cowl mod on a 64 super 21. Still have some painting to do, but that will come later. Nice to have this classic bird back in the air!

io360 A3B6 - facotry new, installed in 64 M20E in 1998. No issues so far, engine is very strong. Compression all north of 75, consistently over the years. Years - 15 years hours - 1550

The yokes were done by aero comfort in San Antonio. Had the interior redone 4 years ago. Very happy with their work!

This picture is a little dated, as I did replace the old scanner with an edm700, including ff,oiltemp, oil pressure . It's connected to the 430 for fuel planning. Planning to connect gdl88 to the 430...

Just over a month ago, I ask for advice regarding my STEC 40 single axis auto pilot with GPSS ( talks to a gns430w). 49Y is now at avionics shop for upgrade to STEC 50 (altitude hold). decided to get GDL88 installed also. Hoping to have her back around Xmas. Thanks to all those who offered your advice! This classic ole bird should be yet again improved and ready for the future!

I have the edm700 in my m20e. added oil temp, oil pressure, fuel flow. have it connected to garmin 430 for trip statistics. This is a nice feature! Really like the ability to down the data and analysis. Both units are great, I went with the JPI because I wanted 3 1/8 gauge, and JPI had a nice rebate at the time!

For one one of your cylinders, I would assume that you used a spark plug sensor? If so that cylinder will probably read cooler that a bayonet sensor. The primary CHT will use a bayonet, while the JPI will most likely use the spark plug sensor.

I maintain N1949Y, sn=256. Her first flight was completed by Bill Wheat, on my birthday!

I had Midwest Mooney reseal using their STC, based on a polyurethane process. Its 12 years old with no issues. So far so good.

Wow, great response and advice! I like the approach of fixing this unit, and adding alt hold. Thanks for all your responses!! Rob

Hello - I'm looking for recommendations, as I consider replacing/upgrading my STEC 40 autopilot. The current unit is 21 years old, and is starting to over correct, and is slow to adjust. I have been told the servo's may need rebuilding. This autopilot is a single axis, is slaved to a Garmin 430W, and I have GPSS. It has been a great unit. Here is my question: Should I upgrade this unit, as I understand it can be upgraded to have alt hold, or invest in a new install? And if new install, what unit would you recommend? Also, I'm in the midwest (St. Louis), any recommendations experience with avionic shops would be great.. Have included a pic of the panel for reference. Thanks in advance for your thoughts/ideas..

My mechanic and I just rebuild my flap pump, and the adjustment is very senitive. We set the flaps to fully retract in 10 seconds, and it works very well. Also rebuilt the parking brake mechanism, as it had developed a slow leak. I cannot imagine rebuilding the parking brake mechanism without the avionic access panels....

I'm planning to install the ARI mod on my 64E. Currently have the Lasar lower cowl closure. It yielded no speed increase, but improved cylinder cooling. I like the ARI as I really do not want to give up the avionics access panels. Just completed installing an EDM700, and rebuild the parking brake mechanism. The access panels make work like this so much easier. I plan to go with the sandwiched option.

No I did not. Please pm me and lets talk! thanks...Rob

Do you have the standard 201 2 blad prop spinner, and is it ok? Would be interested...

Knute - Have not heard back from you regarding the 201 standard spinner. lmk if you are waiting on me. thanks.

Wanted - 201 Standard 2 bladed prop spinner for McCauley M20J 2-blade propeller part numbers: 680031-501, 503, 505, and 519. Manual shows the following M20J spinner assembly part numbers: 680031-007, 039, and 515. Looking to install an ARI 201 cowl mod to a 64E, with engine IO360A3B6. Eddie at ARI tells me I need an M20J standard spinner. lmk if you have one! thanks.... Rob H.

I recently went through the same analysis, and went with the edm700, with FF and oilt and oilp. I also got the usb option. I really like my current panel, and the option after rebates, and with my assisting my mechanic, was just under 3k. The data is fantastic, and always run LOP (have gami's, and an IO360A3B6). Consistently burning about 8 gph, 140kts in a 64 E.

I recently installed an edm700, with fuel flow, oil temp and oil pressure. Factory gauge generally read 180-190 temp, while the edm shows 15-20 degrees hotter. The factory sensor is close to the oil return line from the oil cooler, while the edm is installed on the front of the case. My mechanic and I reasoned the the diff is a result of the locations. I have found, as others have indicated in this thread, that running with cowl flaps 1/2 has a significant cooling effect on temps. On hot days, running lop and with cowl flaps 1/2 open, I see oil temps of 205-210. I'm happy with this....

HI, Looking for a good 64 E cowling that has no mods. Most interested in top section of cowl, but would consider purchasing cowl. thanks. Rob H.

I just installed an edm700, and the K factor was on the transducer. It was 29.86. it is very accurate. There is a formula in the operating handbook that will help you to tweak it after several fill ups. Mine was within .3 of a gallon after burning 35+ gallons.

I have a 64 'E' and have also been reviewing the options on cowl upgrades. I am always involved in all maintenance on my Super 21, and will not loose those avionics access panels. So my choice is the ARI, as it cleans up the nose area, and retains the access panels. If I get a speed increase that's great, but not really the driver. Recently upgraded an original JPI scanner to EDM 700 with fuel flow. The access panels really made the panel work and routing of wires and rerouting of other items much easier. enjoy!
