Regarding... [ .The second problem is weight.=A0 At a whopping 625 =

Jim,

Good points.  I'm thinking (hoping) Theilert's 625 lbs includes the
propeller, governor, turbochargers, etc.  TCM quotes 467 lbs for a =
dressed
IO-550N -- with 30 lbs for a supercharger add-on that's around 500 lbs. =
 Not
sure what all the propeller hardware adds to this...  surely not =
another 125
lbs...?

Maybe one of the engine mavens on the list can clarify some of this?  =
I'll
see if I can get more detail on what's included in the Centurion's =
weight
number. =20

With the customer Legacy's coming in well over the spec empty weight of =
1500
lbs, I don't think any of us can tolerate a heavier engine.
