 reduction? >>

Jim,

I have an IO-360-B1B on my Lancair (non-turbo) and I usually DONOT reduce the 
MP until I level off.  If going on a long x-country trip, the power reduction 
becomes automatic as altitude is gained.  On short trips, I reduce the MP 
when I get to about 3,000 feet and no longer climbing.  The extra fuel (fuel 
enrichment feature of the engine) helps quite a bit with cooling the engine.  
This enrichment feature only comes into play at full throttle.  If I reduce 
the power too early, the fuel enrichment feature shuts off and my CHT's goes 
up the roof!

I do, however, reduce the rpm as soon as I get to 120 knots and climbing 
(around 2,300-2,400rpm), mainly to reduce the noise levels, both inside and 
outside the cockpit.
