It is a lot of air...when driving and at highway speeds. At stop lights and bumper to bumper it is not adequate for a modern R134condenser setup as the pressures will elevate too much resulting in poor cooling and or compressor cut out.
This is a good thread on some earlier condenser fan setups. Jim Sims(RIP) knew the science...but not all listen... and still argue the world is flat....
