I've seen a couple of fan configurations on WBX radiator cores that I've
removed.
Some have a very nice Audi/VFW fan with multiple speeds. It really puts out
a breeze but it's concentrated in about 30% of the radiator area.
Then there is the two fan configuration that pretty much covers the whole
radiator area and has two each, 2 speed fans that don't seem to blow that
hard but cover about 85% of the radiator area.
I've also seen auxiliary switches that automatically turn the fan on high
speed anytime the idle drops below 1000 rpms (approximate on a micro
switch).
If overheating is a cvonstant problem I'd be checking my timing and possibly
go to a lottler hotter spark plug so the engine didn't lug from running too
lean in hot weather.
