Bigger is Better!!   Remember the extra weight is all going into
horsepower.

You can expect much better climb performance on a hot day/heavy
airplane combination with a bigger engine.

I installed (shoe horned) a Lycoming IO-360A engine into my Lancair
and although it required major modifications to the cowling, it sure
performs nicely; especially since it has 10:1 pistons, etc.  Lycon of
Visalia says it produces 241 hp but a more realistic figure based on
how much hp you get from increasing compression, fuel flow data, and
flow balancing would probably be around 220 hp - about 10% increase
over the stock 200 hp engine.  Cruise speed is about 210 kts.  I get
consistent cruise speeds in excess of 200 kts at any altitude up to
about 13,000 ft.  I typically flight plan for 200 kts and if I find I
have a head wind, I push in a little more throttle or RPM and make
some of that head wind go away.    I believe these cruise speeds are
about 15 kts above most Lancair 320's with constant speed props.

Another nice trick is to put a ported and flow balanced Lycoming 0-320
into a Lancair 235.  Steve King has one of those babies and it really
performs nicely.
