My Acclaim has the continental version of Gami. My #2 Cylinder runs consistently 50 to 75 degrees warmer EGT. Is it possible to call Continental and have them make an adjustment for that injector? Has anyone done this before. Any advice would be greatly appreciated. Jim M Sent from my iPhone using Tapatalk

Will you please describe how to do the big pull. I’ve read about it but not sure on how to do it. The Salesman that sold me the plane showed me how cool the temps were at level off and stressed going real slow with the temperature changes as there was going to be 150 to 200 degree changes and you want to do that slowly. So could you help me out with this big pull. Sent from my iPhone using Tapatalk

Well thank you for the feedback! I do appreciate it. I’ve been out of GA for 27 years and have only recently got back in it. I read articles and try to educate myself the best I can. I appreciate your input and years of experience and value what you have been taught and have experienced. Some things don’t translate from the Business Jet world back down to the piston world. In the Global we always do reduced power takeoffs unless conditions dictate otherwise. The engines are rated for takeoff power for 5 mins, all engines operating, or 10 mins on Single Engine. So it’s normal for me to have reduced power in the climbs. When I read articles about these big continentals and see all these cylinders being replaced like on the one I bought, I am naturally predisposed to wanting to take it easier on engine. I’ve only tried the reduced power climb 3 times and each time the climb rate 1000 to 1200ft/min so performance was not significantly reduced at all and the CHTs and TITs were easily within the range with a decesnt reduction in fuel flows. So, I was thinking as long and I’m not heavily loaded why not? Like almost anything, you can find your data to support the point of view you are seeking. You mentioned several types of folks. Well, you left out a type. I’m sure there are others. But, I am the type that listens a to information being presented, does additional research to verify and try to acquire all available information and then come to a conclusion. I am the type that will learn from mistakes and help others to not make the same ones by presenting the material to help them. I watched several YouTube Videos on the Acclaim and all the information presented in those videos and the Training that you received and the Realization that the engine is already quite de-rated at 280hp, that even at TO Power it is not being stressed. You and others also pointed out the other reasons why the cylinders weren’t making it to TBO. I appreciate everyone’s input. Maybe this thread will help any new acclaim owner not entertain this idea of “saving” the engine for longevity. I appreciate everyone’s input. [emoji120] Sent from my iPhone using Tapatalk

https://www.avweb.com/features_old/operating-tips-for-big-bore-continentals/ I think this guru has something to say about leaning in climb. I’m just learning here and trying to take in as much information as I can. Discussion is good and makes us all better. How does this article fit with the M20TN? Isn’t 30.5” and 2500rpm 75% power? It you run take off power for 2 to 3 mins and then reduce to 75% and you climb and cruise at 75% isn’t that less stress on the engine as long as temps are appropriate? I know the manufacture has to have a published climb profile and power setting. That’s where you get your performance data from for planning purposes. But you don’t have to always climb at TO power. It’s not a limitation. As long as you are operating the engine within the limitations of the POH and Engine Manufacturer limitations why can you not make adjustments that may increase engine longevity and operational efficiency? There are many occasions where the aircraft manufacturer and the engine manufacturer don’t see things in the same light. One is trying to meet performance goals against competing manufacturers while the other is trying to reach longevity goals or win a contract for the airframe. It’s hard sorting everything out. But all of this is a great learning experience and I am grateful for the discussion and various points of view. Sent from my iPhone using Tapatalk

Learned a lot from reading this thread. Thanks a lot. Us newbies need all the help we can get. No sense in reinventing the wheel. Sent from my iPhone using Tapatalk

So whoever did the SB before didn’t patch the tailpipe but manufactured a makeshift plug for the exhaust nipple that the hose connected to. That’s what prompted him to think it was installed incorrectly. Which it was because the nipple was supposed to be removed and patched over. SMH [emoji1751] Sent from my iPhone using Tapatalk

Oh shoot!!! So he put it back into a condition requiring inspections! That wasted some money. Sent from my iPhone using Tapatalk

I have a question regarding the coking issue. My breathing tube was not connected to the exhaust pipe. My mechanic noticed it and connected per a service builten. Did a later service bulletins take it off the exhaust? Or was that improper? Sent from my iPhone using Tapatalk

The TIT comes into play when there is too much fuel due to atmospheric conditions. 1350 to 1450. So TITs below 1350 would be a reason to lean in the climb to keep the fuel air mixture in the proper range. Initially I was running things too cool and too rich and had some spark plug fouling. Another operator suggested to lean a little while taxiing before and after landing to help with not fouling the plugs and also suggested the reduced power climb for longevity and to give the ability to lean in the climb keeping in mind the other engine parameters. The drop off in performance was only about 200ft/min. Still able to climb over 1000ft/min. Most of my climbs were to 12,000 ft and below. I just make my first flight at 15,000 the other day come back to FL from KATL to try out this O2 canula thing. I’m used to pressurized aircraft. It wasn’t too uncomfortable. Might use it more often now. I appreciate your input and effort you have put in to help bring me up to speed. I’m beginning to get the sense that Acclaim pilots enjoy the speed and power and live with the fact that their cylinders typically don’t make TBO, even if they have purchased a factory new engine. Unless they have a great mechanic that properly adjusts the valves. Read that in another post. My engine has had all the cylinders replace around the 650 mark and 2 more replace since then. On the prebuy they replaced another one for compression, leaking at the valves. Both turbos got replaced at the 600hr mark by a service bulletin. So I guess I was a little predisposed on taking it easy on the motor. But I guess 32”MP and 2500 is taking it easy already on a motor that can run 38”MP and 2700Rpm in other configurations.

I have just used the 2 cards in the MFD. Haven’t touched the PFD Card. I’ve only done it twice and it seems to work as instructed. Sent from my iPhone using Tapatalk

I would greatly appreciate a copy as well. [emoji120] Sent from my iPhone using Tapatalk

I agree with everything you posted there. Not trying to blow this out of proportion. The POH doesn’t publish any reduced power climb power settings. That doesn’t mean that it is a limitation and you must always climb at full power. Folks may want to climb at reduced power for various reasons. All I am just pointing out is that the engine manufacturer and the POH says above 30.5 you have to be full rich. Below 30.5 you can lean. The POH also has a note right below those three published climb profiles that actually says “Leaning may be required during CLIMB depending on atmospheric conditions. If I’m not heavily loaded and, not going far and I don’t want to run full power above 3000ft agl for whatever reason, there is nothing wrong, that I can think of, to reduce the power to 30.5” and lean to keep the TIT between 1350 to 1450.

Well If you keep full power you are not supposed to. But if you pull it back to 30.5MP or less there shouldn’t be any problem doing so as long as temps are in proper range. Do you know of any harm that I am not aware of? I keep the TIT at 1450 or cooler and at 120KIAS the CHTs are below 375? Sent from my iPhone using Tapatalk

You shouldn’t lean above 30.5MP. Above 3000ft I pull it back to 30.5 and lean for the climb keeping it around 1450 for the climb. The CHTs are usually well below 375 or so. Then at cruise I’ve been using 29.5MP and 2350 RPM. Lean how you like. At 15k to 16k you will get around 205- 210 TAS. Sent from my iPhone using Tapatalk
