I would not choose to operate with a clogged, dirty air filter because it chokes off the air flow, so why would I choose to choke off the airflow with the throttle plate? The engine doesn't know how the air flow is being restricted. Think about it. Walter On Dec 30, 2004, at 1:29 PM, Marvin Kaye wrote: Posted for "Chatfield S. Daniel" : George, Isn't the "improve the critical altitude" concept also true for normally aspirated engines? Say if you normally cruise at 75% power... and you are at 5000 ft at 24X24 and you pull the ram air...your MAP goes up 1.5 inches...in order to get back to 75% you pull the MAP back 1.5 inches to 24??? So the advantage is above 8000 ft. Right? Chat Daniel N678RV N891AC (reserved) -- For archives and unsub http://mail.lancaironline.net/lists/lml/
