test runs from a while back

haoye 51 mm fan 7 blade
LSJS 5000 kv motor(not real sure of the kv) with the "alpha fan extension"
35 amp thunder power esc
3s 2200 and 4s 2200 thunder power 25c packs

3s settled in at 11.08 volts and 22 amps peak amps was 24.5 at startup
4s settled in at 13.5 volts and 29 amps peak amps was 34 at startup

did not get an rpm reading.
did not attempt to measure thrust.

the folks at little screamers, scott or bob, can give ya the actual kv of the motor. a little screamers jet screamer.

didn't test with the wicked motors from donsrc.com
would expect similar results, though

maybe those numbers will help you find the thrust ballpark you are looking for.
