    To Powerflow or not to Powerflow - That is the question

    It does weigh more. IDK exactly how much more. I have seen numbers ranging from 6 to 13 pounds more.

    IMO Powerflow may give you the flexibility, depending on your engine, to increase your TAS by a couple of knots with the penalty of more fuel flow, or save that fuel and go your “normal” couple knots slower. But realistically flying a Mooney you may not do that. I know I probably wouldn’t. Of course you can increase fuel flow and RPM and gain those couple of knots without the expense and permanent weight gain of powerflow. It just doesn’t offer a significant speed increase and four grand buys a lot of fuel as does three grand or two.

    Nah, I’ll pass. Thank you. May expose what you don’t want to hear and risk being called bitter. We all are capable to do our research and make our own decisions.

    To Powerflow or not to Powerflow - That is the question

    The op posed a question and asked for input: “I've been told by my shop that he has have removed as many of the Powerflow systems as he has installed (excessive noise seems to be a majorcomplaint) I've read about the advantages of the Powerflow but I'd also like to hear from anyone who has had theirs removed and gone back to stock and why. I figure if the shops are removing 50% of the sysytems, someone will surely be able to chime in. Thanks in advance for your input!” In the interest of objectivity I was presenting to him powerflow’s own numbers which may in all probability explain why they are being returned. I regret that’s not good enough for you and you view it as negativity. I’d suggest you take it up with powerflow. Nevertheless thank you for your opinion. No apologies here however!

    Which concepts of arithmetic give you the most trouble? Multiplication and percentages? The point is how poorly the PFS scavenges the spent exhaust gases when compared to stock in view of its cost.

    This not withstanding, there are concerns that have been raised by customers about reliability and about customer service that has been lacking. These issues have set EI apart from JPI. Bashing JPI on the EI website probably didn’t help. Although both offer functionally similar products with similar cost JPI is viewed by aircraft owners and installers as more reliable and offering excellent customer service. In your estimation are these concerns valid and how can you reassure potential customers that you have addressed them?

    @oregon87 how does the reliability of your monitors compete with JPI in your estimation? I’m in the process of deciding and I’m leaning towards JPI based primarily on reliability track record. Thanks.

    Powerflow says a stock exhaust leaves behind about 20% of spent gases while their exhaust allows almost 95% intake of pure fuel air. Difference being about 15%. So they are being removed because a 15% difference at best does not warrant a 222% in cost over stock.

    Fuel efficiency in headwinds

    Carson's speed gives the best speed to fuel flow ratio. Not to be confused with best mpg speed. So if the goal is to get there without overly wasting fuel fly Carson's speed.
  10. If it’s the pitch servo you are looking for it’s the one that has a bridle cable through a capstan on it and going back to the elevator. It’s located aft and away from the trim servo. You can’t miss it! You can see the cable aft and fore. The capstan is underneath it. Here are some drawings:
  11. I’m sorry I don’t have any photos. What pictures are you looking for? Mine would intermittently not hold altitude. They repaired it with brand new King parts.
  12. I’m not sure your opinion reflects reality. I had my King pitch servo repaired for the first time after 26 years in service by Autopilots Central a few months ago. The repair cost me $745.00. I also bought another one they had overhauled and ready to install to have as a spare. I paid $1450.00 for that with warranty. So for $2200.00 I got two pitch servos.
  13. Aeroshell 15W50 contains a advanced additive package that’s specifically formulated for the multigrade oil that it is. It also contains the Lycoming LW 16702 antiwear additive. If you don’t want to use the multigrade you have the aeroshell W100 plus and W80 plus. The plus designates that they contain the Lycoming antiwear additive. After market additives are not recommended by engine manufacturers. And when selecting among these oils there’s never a good reason for costly after market additives. Personally I would advise you to use a premium aviation oil such as Aeroshell that’s appropriate for your climate. Fly it and change it religiously as directed by the manufacturers (of engine and oil) every 30-35 hours or 4 months. Let the pros at Shell do the formulating!
  14. Is there some data, as is for Mobil1, that indicates that the Aeroshell 15W50 formulation is unable to hold lead salts in suspension? How about for the Exxon Elite? Because Shell, and Exxon for that matter, clearly disagree. And this is not a new formulation. Aeroshell 15W50 has been around for almost 40 years! It would be interesting to see some data that looks at synthetic/mineral ratios. In other words how much of each attains a balance which optimizes the benefits of each.
  15. We agree that fully (100%) synthetic oil presents challenges to engines with leaded fuel. See Mobil1 for example. Aeroshell 15W50 is not fully synthetic. Also it was developed in cooperation among Shell, Lycoming and Continental. https://prodepc.blob.core.windows.net/epcblobstorage/GPCDOC_Local_TDS_United_Kingdom_AeroShell_Oil_W_15W-50_(en-GB)_TDS.pdf
