<x-flowed> <<<<<<<<<<<<<<<<--->>>>>>>>>>>>>>>> << Lancair Builders' Mail List >> <<<<<<<<<<<<<<<<--->>>>>>>>>>>>>>>> Jim, Q--: Can the turbo'ed version of the IO-360 get by with 80/87 or the forthcoming 82UL? A-- No, All TSIO-360 engines require 100LL. Turbo-normalized engines will make the equivalent power at altitude but the intake air temperature created by the turbocharger reduces detonation margin. The IO-360-B engine is only 360 certified for use with 80/87. It is 180 bhp @ 2700 rpm. It has 6.5:1 compression. Q-- If so, I would think this would be an attractive alternate engine for the ES. At altitude with the turbo-normalization, my guess is that the performance numbers would not be far off those for the Super ES with the IO-550. A--TSIO-360-MB would be the engine of choice. It is 220 bhp @ 2600 rpm with a MAP of 38 inHg and a service ceiling of 19,000 ft. The IO-550-N only makes 220 bhp below 10,000 ft. The TSIO-360-MB weights 354 lb vs an IO-550-N at 428 lb. Q--Orrin seems to have a nice turbo 360 setup in his two-seater. Comments? A--Yes, but it's the wrong color!
