Thanks gentlemen, I think the one avionics shop may have been misinformed or didn't know. I'm researching this now. I do like the GI 275 as an AI and I have a used EA-100 that I purchased awhile ago. Does anyone have an estimate in hours to install the EA-100 and a GI275?

I have the EA100 but want to get rid of the vacuum system, hence the vacuum driven AI and it's function with the autopilot

I want to clean up my panel and remove the vacuum system by removing the KI275 AI that now controls the KFC 200. I was just told by an avionics tech that he's pretty sure that if I install the GI 275 AI+ AP I would lose all the functions to control my KFC 200 through the Aspen 1000 pro max and would have to use the GI 2715 instead. I like that the Aspen has the heading function, GPSS, minimums, altitude and shows the approach features. To be fair, he's only installed one before so isn't completely certain. Is this right or is there different ways to configure the 275 and leave the functions of the Aspen but have the 275 for some AP functions as well as being able to remove the vacuum? Thanks Steve

Something similar happened to me when I was making a night landing at an unfamiliar airport. I was watching my airspeed and when I was close to landing I felt very uncomfortable and noticed how fast I was going. I think the wind was around 10-15 G 20. Very lucky I didn't run out of runways so I went around knowing I screwed up and then turned a 180 and landed the proper way, against the wind. Because of that I now on every landing during on short final, I check my IAS against my ground speed just to confirm the wind direction. If your IAS is 70 and your GS is faster, then you've a tailwind. And of course if the IAS is 70 and your GS is the same or less you've a head wind and your ground roll will be book or less.

Good point, I hadn't considered the ram air factor. 99% of the time I do catch or control the MP still there must be a way to limit the MP. I understand the large differences between a 252 system or for that matter most other wastegate/ turbos so I was hoping that an adjustment or different style of waste gate/ upper deck controller might have been designed for our Merlyn systems. One positive mention of the issue is that the turbo system is working very well

I'll set the MP to 37" while rolling and taking off then watch it stay there however it will creep to over 42" while climbing and cleaning up the plane unless you're constantly watchful. I'd like to be able to be able to adjust either the wastegate or the pop off valve similar to a normal system to stop any over boosting. Unfortunately it looks like it's not possible with this system.

Just curious on the setup for a 231 (TSIO 360 LB) with an intercooler and a Merlyn wastegate. I take off trying to hold the MP to a maximum of 37 inches / 2700 RPM then pull it back to 2600RPM, however the MP has crept easily to over 42 " where I quickly pull it back to 37". First question: Is this the proper way to run this engine per MP and RPM and what should the fuel pressure be at 37"? Second question: Is there a way to control MP other than the throttle? Steve

Looking for three good condition or rebuilt complete cylinder assemblies for a Continental TSIO360 G, Mooney M20K 231. PN 658822A1 Thanks Steve 519 589 7034 sdawson630@gmail.com

You're not going to use a PT6A for a Mooney but probably the same Alison 250 as in a Silver Eagle so the weight would be less for the engine, but you'd have to do some frame work for the W&B as well as getting the aircraft higher off the ground to increase a larger prop and they weigh about 250 #'s. It would be fun to try but I think I'd rather buy an Acclaim Ultra with a TN 550 and save fuel and frustration. Now if they could pressurize a Mooney,

I've used Bill Davidson for 15 years and he's been great to work with. His prices are fair for complete coverage. if your interested get ahold of him or hIs son Laine. They're in Oshawa so close to you. Davidson J S Insurance Brokers Ltd 1 905 683 8986

I believe they priced out the complete Dynon package including EIS, Autopilot, 10" screen ect so the price would be higher than just the AP addition

I just looked at their site and they haven't yet given a total for the J/K however for a Beech V35 the total parts are $30K plus installation. How does this compare against a Garmin G3X with autopilot?

Just a suggestion, try looking for a used tank that's newer then your existing and has a manufacturing date younger than yours. Depending on the date stamped on the tank you may have time left even before its next hydro-test Possibly eBay, or salvage yards may have one. As for the regulator don't send it to the rebuilder in Quebec. Parts are scarce and a rebuild will be north of $5K CND.

After just one year and approximately 70 hours the coupling from my 231 just stopped working again. I don't want to get another rebuilt one from Spruce and have this happen again. Does anyone know where is the best source to get a new one quickly and how to check for quality?

I just posted about these on another thread on MS. I believe I bought mine a year ago on eBay or through Amazon. The tabs on the side are easily removed with some snips and then file off the leftover tang. These will work until the replacements are available.
