Wider is not the problem now, I need taller.

The core measures 14"H x 24"W x 2 1/4" thick with a 2 row all aluminum. This core fits a 3.0 v6 Taurus.

I think I am going to install a ball valve and slow the water flow down and check the temparture difference of the air flowing across the radiator to see if it increases or decreases as it is slowed down.

I may just need a restrictor I am sure they have the same problems with race cars turning extremely high engine speeds.

Maybe even an electric water pump?
