Highest flowing CFM electric fan that ACTUALLY fits?

I currently have a Champion 22" aluminum radiator and a duel fan set up .the snout of the water pump barely fits in the space between the 2 fans...problem is they don't flow very high CFMs....

It runs 200+ in traffic and or more on the highway.
If I manually turn the fans to full blast (I have an override switch) if does cool down to a nice 185.....
