I have an older 601 with the stiff legs.

I am getting significant air into the area under the seat and rear fuselage. 

I installed a small scoop at the back under the tail and built covers for the gear box.

All the holes under the belly have been scooped with a punch so they draw air out. 

There is enough air pressure that makes the stick boot puff up like a balloon. 

Any suggestions where all the cold air is coming in?

An sealed rear fuse access hatch? Assuming you have one. I put a thin strip of weather seal around the opening.

Steering rod holes/boots
