Radiator sizing. need an expert

Oh yeah so that guy at the drags who had that Renault, which looked to be awesomely engineered in every possible way.

 

He had a radiator fan shroud, that covered the whole radiator. But the fan was mounted to one side...

Then on the other side there were two square flaps hinged on the back face of the radiator shroud.

 

So this meant that when the fan was blowing, it would pull the flaps shut and seal the shroud so all of the air would come through the radiator, and out the fan.

 

But when there is more pressure inside the shroud than behind it, (More air is flowing through the radiator than the fan can deal with) the flaps open to let the air bypass the fan.

 

Bloody good idea!

 

Although his radiator was tipped over a bit, so not sure it would work as well for one that's standing upright.

Some cars come/came with this factory in plastic shrouding.

Yea electric fans are cool, those ford Taurus/volvo ones that KK and myself have are insane. Pretty sure it moves more air than the giant engine mounted hoofer.

been using mondeo twin fans on my stuff. they move plenty of air as well. only need one unless doing skids
