A/C experts- more flow?

[twin plugged targa]

Okay I know it is near the end of Summer, but,
My A/C does not seem to have the air flow it should have. I have compared it to other 911's of similar age and they have a greater flow. Which fan does this cold air flow and can the fan itself be upgraded or could the ducting be at fault?.
The air seems cold enough, it's just there is not enough of it!.
The vent opening looks as large as the post 86 911's .
Any suggestions?.

Hello

Maybe it is time to clean the evaporator ?

A lot of air can leak out the gasket material that seals the fan, fan housing, and air intake hose near the feet of the passenger. Old hoses can be like the picket fence around the garden. Lots of places for the wrong stuff to sneak through. Redoing all these old gaskets and hoses is a real pain. Very tight spots and very fragile a/c hard tubing.
