Alga - having a stat in there that is jammed in is fine - remvoing it totally is more of an issue. The stat acts as a restriction in the coolant flowpath and as a result helps to balance the flow to different areas of the block. If you remove the stat then you give the water an 'easy' path through the engine that can result in the engine overheating becuase you don't pick up as much heat.

I had this problem with a engine on the dyno that would constantly overheat no matter how many extra water pumps we added In the end we realised that the thermostat had been removed and the water was just going around the system picking up very little heat - popped a thermostat back in and it cured all the problems.

it effects the ballance of flow around all the cyl liners
minis used to boil 3&4 and cool 1&2 with the stat pulled out st did a flow restricter ring to replace the stat to ballance the flow
its the same reason why you dont change the size of the coolent holes in a head gasket (and yes i have seen it done try it and you will find out )
