Continental TSIO-360 power rating
Can anyone explain why the Cont TSIO-360 engine (say EB model as fitted to many Seneca IIs) is rated at 215hp at 12,000ft, and 200hp at S.L?
In the POH there is a reference to an 'orifice' in the turbocharging / induction system being 'set' at 12,000ft. This is an engine with a fixed waste gate from what I can tell, so what is this orifice? I'm guessing that with the throttles fully forward at 12,000ft you'd get 40" MP, descend and the MP would increase (if throttles remain in position).
Illuminate me someone....
