Craig,

I only have 100 hours on my IVP and have stopped to do a lot of mods.
The numbers reported by others seem consistent if you take into =
consideration how the airplanes are equipped and the power setting used. =
  I'm expecting 260-270 LOP up high,   but actually down low tends to be =
the governing situation.

I got a piston because I wanted to be able to go very far with minimum =
stops.
For your mission, the turbine might not be a bad match and they are =
incredibly cheap right now.
It actually does have really good top speed.

...but to own a LNC4 you have to be willing to know everything about the =
airplane and tinker some.
If you are even thinking about a Mooney Rocket you might want to think =
really hard about if you want
to spend the extra time to own an experimental.   A Rocket with TKS is =
pretty cool and will get the 220 KTAS.
...plus you can have your mechanic maintain it, you can sell it, and =
it's insurable.

If you do go the LNC4 route, there is huge variance in the airplanes in =
tank capacity and in how well tuned they are for speed.   Read Fred =
Moreno's papers on the lml website to get just an idea of how far you =
can go.
