So im my cab, im exausting the room almost 3 times every min.

Ideal I think is to just move the clear the room of the stale air once every 60 secs. But im sure Ideal is relative.

So anyhow, using the info above you can see what u need :} remember exausting more hot air = cooler temps.
Dude i think ur math is wrong....4Lx2Wx6H=48 cubic foot not 108.....
