Guitarmaster Posted September 16, 2016 Report Share Posted September 16, 2016 Last year I took the 400 out for a max power run at 2500', the best I could get was 240 mph indicated. I will do it again soon after a few mods. Clarence Now you're just bragging Clarence.... . Lol! Try putting one of Chris's girls in that 400, she'll slow down!

INA201 Posted September 23, 2016 Report Share Posted September 23, 2016 Does anyone run their cowl flaps flush with the fuselage when they are closed? Mine are set to about 1/2 inch open in the closed position. I looked it up in the manual(1978) and it says flush or 1/4 inch open during operation in hot environments. How about the propeller alignment? Is 1/2 inch off worth fixing/shimming? Quote Link to comment Share on other sites More sharing options...
jetdriven Posted September 23, 2016 Report Share Posted September 23, 2016 Yes, close the cowl flaps and shim the lower mounts. I'd guess you'll need a 1/16 on both sides, maybe an 1/8" on the pilot lower side instead. In the race to Oshkosh I ran the engine 80 ROP even at 28-29" MP and it ran below 400 for the race.

Guest Posted September 23, 2016 Report Share Posted September 23, 2016 I've found that shim thickness to engine lift is about 1:4 Clarence Quote Link to comment Share on other sites More sharing options...
mooniac15u Posted September 23, 2016 Report Share Posted September 23, 2016 Have you verified that it's not a cowling alignment issue? They tend to ride up as the edges and fastener holes wear. Quote Link to comment Share on other sites More sharing options...
Oldguy Posted September 23, 2016 Report Share Posted September 23, 2016 We had a good talk at last year's Mooney Summit where Bob Kromer talked about cowl flap adjustments on J's. He said during their testing, if the cowl flaps were fully closed, the airflow actually came forward from the engine air inlet due to compression in the compartment. I seem to recall he said they determined an opening of 1/2" to 3/4" at the rear of the cowl flaps provided better speed and cooling for the J. From most of the ones I see, there that seems to be the norm, but YMMV. 3 Quote Link to comment Share on other sites More sharing options...
Steve Dawson Posted September 23, 2016 Report Share Posted September 23, 2016 Has anyone noticed a speed penalty or increase combined with a change in engine temp by either opening up the cowl flaps or having the baffle seals very tight?

Piloto Posted September 24, 2016 Report Share Posted September 24, 2016 Check that the A/P auto trim function is working by disengaging the ALT mode. If the plane start climbing or descending the auto trim is not working. The conflicting surfaces (stabilator vs elevator) will increase drag thus slowing the plane when in altitude hold.

Curtis Posted January 24, 2018 Report Share Posted January 24, 2018 So, doesn't this discussion beg the question............Why the 201? It doesn't sound like anyone is breaking the 200 barrier except for Jet Driven. I fly an archer and can get 140 to 145 knots out of but want to move to a m20j for the 30 knot jump. It doesn't sound like I'll get much more than a 10 knot jump. 1 Quote Link to comment Share on other sites More sharing options...

Wide open, full rich, down low, washed and waxed, no induction leaks, cowl flaps closed, 201 mph should be possible. Not recommended for frequent operation if you want long engine life. I have recently demonstrated book speed of 165 mph indicated when WOT / Full Rich at 1300 msl / 1000 agl. The J has more power and less drag, shouldn't have a problem doing 201 or really close to it depending on rigging. Quote Link to comment Share on other sites More sharing options...
DonMuncy Posted January 24, 2018 Report Share Posted January 24, 2018 Speeds in aircraft are almost meaningless. My wife was upset after we bought our 231, and I flight-planned short flights at 155 knots. Yes, I fully believe that under the most extreme advantageous conditions, a 201 did 201 mph and a 231 did 231mph. But one has to ask how fast I am going to cruise, using the settings I plan on realistically using. Curtis needs to compare the speeds he experiences in the Archer and the 201 speeds using more or less identical percentage power settings. (I know nothing about Archers, and perhaps the numbers are only 10 knots difference.) 1 Quote Link to comment Share on other sites More sharing options...

Certainly they won’t cruise at that speed. Clarence I can do around 172 KTAS all day but it’s low altitude, usually turbulent at that high of an IAS, and terrible for fuel. But 172 KTAS and 16 GPH is the standard Bonanza profile so I can do that if I want to. I’m not sure how it’s harming engine life. It is running at 2700 RPM, ROP and it’s 330 CHT. Like every takeoff but cooler since the IAS is so high. I think it likes it. Edited January 24, 2018 by jetdriven Quote Link to comment Share on other sites More sharing options...

The Archer is a great aircraft and Piper's best all around 4 seat aircraft IMOP but easily 35-40 knots slower in my experience. Quote Link to comment Share on other sites More sharing options...

He's probably llooking at groundspeed, and forgetting that the wind doesn't always blow from behind, or that strong. 2 Quote Link to comment Share on other sites More sharing options...

That's the same speed as my Mooney, same engine, I've got constant speed, lighter, smaller frontal area, and retractable gear. The 180hp Cherokees' I've flown will barely crack 120, on a good day 1 Quote Link to comment Share on other sites More sharing options...
