Delta-V for a Hohmann transfer between LEO and GEO.

Start in a 200 km circular 9.1 deg orbit. The initial orbit and transfer orbit mass are acheivable by a Falcon 1e rocket.

The Falcon 1e can lift smaller masses into higher orbits so this is not necessarily the best you can do with the Falcon 1e.

Since version 8.
