I run a Ron Davis radiator with the 2 fans and a Meziere pump. My inter-cooler is a horizontal mount but I also have an a/c condenser. Been thinking about adding a pusher fan in the front.
I had been dealing with engine issues pressurizing the cooling system so I can't say how well it does or does not work. My turbos are water cooled and that does not help.
I will be looking into an oil cooler soon.
