Ladies and gentleman, If you can help me out with this discussion. I am getting into process of building 360 MKII with long cowl and long engine mount. I have been doing a lot of brain storming about which engine to put in, and here are some of the conclusions, feel free to comment ---- I have been looking at IO-360 with stock 200HP+ engine. It is typically angled valve engine I find it to be too expensive for what you get. It is a smoother ride by heavier cause of the counter weights it has for torsional harmonic suppression on crankshaft. It is a lot of money and weight penalty for a slight increase of performance. I see guys actually using short mount with this engine if you go for three blade MT prop ---- Regarding prop, if you want three blade, the best solution on the market I found would be MTV-12-B/175-59b ---- For Lancair 360 MKII airframe I find it optimal to go with ECi IOX-360. With 8.5:1 pistons, ECi is claiming to have 188HP. ECi cylinder seem to be very advanced on design. I feel that I would benefit with going additionally with front-horizontal cold air induction and 7deg angled intake. I feel that angled intake is actually a way for you to line-up with cowl front air-intake I am not sure, if this engine with cold air would fit standard 360 long cowl, or I would need to perform some modifications (with cold air, engine is higher)?!.. let me know if you know more If used with three blade MT prop, you do not need counter weight on crank. That prop can take more abuse Superior has a similar product, XP-360 Similar configuration to ECi, cold air and everything... But they do not have advance cylinder design as ECi does. But they do have revolutionary new camshaft and roller lifter design, which is not available with ECi engine. I feel that roller lifter design is not significant performance gain. As far as I am aware XP-360 is rated to 180 HP I do not want to offend anybody here, I am just openly expressing my amateur overview on possibilities I had a chance to investigate, I am open to all comments and suggestions on this subject Thanks All!! -- Miro Vidos from WebMail -- Miro Vidos from WebMail
