Lrn2Fly Posted May 30, 2015 Report Posted May 30, 2015 This is what an M20K model sees as it passes a '66 E model: The K model is at high cruise power settings, and the E model is at 23"/2400. https://www.youtube.com/watch?v=4KZeqLZ8_JM
Ned Gravel Posted May 31, 2015 Report Posted May 31, 2015 Is it just me, but at 3,500 feet, will an E model at 25"/2500 perform almost as well as a K operating at 35"/2500? Although the altitude was relatively low, this E was dialled back a bit and still, the speed difference is not that large. I am certain that even at 5000' or more, the difference would have been much greater.
Shadrach Posted May 31, 2015 Report Posted May 31, 2015 An E model at wide open throttle should hold its own with a K at 3500'. 23" 2400 or 25" 2500...not so much.
Lrn2Fly Posted May 31, 2015 Author Report Posted May 31, 2015 A video is worth a thousand pictures! The E model being passed is almost stock, except for the one peice windshield and the cowl closure, with a 1400 hour IO-360 engine. There are no other speed mods on this airplane. The K model was at 34" and 2500 rpm's, and our altitide was 2500' over central Florida. Above 5000', the K model would have been benefitting from the turbo charger and running away from the E model, much more noticeably, instead of walking away.
