aidanf Posted June 20, 2017 Report Posted June 20, 2017 Its been a month !!! - where are the numbers - I would expect pitchforks and tar and feathering at this point:) Just joking, but with this much focus on this project and its potential benefits I am sure everybody wants to know 2 Quote

I've since learned that the baffling I'm using is too tight to the # 2 & 3 cylinders. We put some spacers in between the baffling of these cylinders and the temps have decreased. I'm working on a kit to install that will give more clearance and hopefully get the temps lower. They aren't crazy high but a little higher than what it was prior to the mod. Performance flights haven't been done that I'm aware of to gauge any increase in speed. Thanks, 2 Quote
mike_elliott Posted June 20, 2017 Report Posted June 20, 2017 David and Cindi will be at the Mooney Summit V with their fantastic cowl mod. Airport day, open to all, will be Friday Sept 29th where David will have the mod and will speak about it. David, bring your order book, I think you will need a big one. 4 Quote

Sabremech Posted June 20, 2017 Author Report Posted June 20, 2017 The line right now as I know it, Matt, Marauder, and Bob. Matt being within close distance to me will make Marauder and Bob's go much easier! Thanks guys! 3 Quote
orionflt Posted June 20, 2017 Report Posted June 20, 2017 remember, you still have to work on the older C cowl! Quote

orionflt Posted June 20, 2017 Report Posted June 20, 2017 I'm slated to have my plane at weep no more in January, lets see where you are with it before that. Quote
jamesm Posted June 21, 2017 Report Posted June 21, 2017 Curious ... Doesn't the 'C' and 'G' models share the same firewall forward engine and cowl setup ? I would have never guess an increase in CHT hum interesting. From what I heard for several source the air exit outlet area is suppose to larger than the air inlet area at least as I understand it. Just when I think I understand something.... Quote

Or perhaps after KOSH if down time can be kept to 4 weeks or so. The former would be safer I would suppose. Quote

Guitarmaster Posted September 4, 2017 Report Posted September 4, 2017 I think David is still working on the 337 for my airplane. We have kind of tentatively planned to get it in the end of August but the speed at which the FAA moves is not, shall we say, expeditious.In the meantime I have done some premodification flights and have come up with a solid 147 Knots true airspeed at 6500 feet running wide open throttle with ram air open at 100ROP. I recorded all the conditions so I can replicate them after we get the mod installed.Sent from my XT1585 using Tapatalk 5 Quote
Sabremech Posted September 5, 2017 Author Report Posted September 5, 2017 I'll be starting the Mod on Matt's F model next week. Hope to knock the time down to complete the mod to a couple of weeks. Pictures to follow when mod completed. Thank you, David 3 Quote

Sent from my XT1585 using Tapatalk Expand My former 1967 F was a fast F 148 Knots true at 7000 WOT and high RPM on cold days. Used a four way cardinal run and averaged the speeds with GPS ground track. With the ram air it was 152 knots true but I did t used the ran air unless in VMC conditions and the only about 1/4 of the time. I had the laser closure and the calipers reversed. A few fairings may have also been on there and flap and aileron gap seals. Original two place windscreeen - retractable step. If I had not sold my F and upgraded to my Missile I would have gotten in line for this mod. -Seth Edited September 7, 2017 by Seth Quote
