[TR] Electric Fan Location

[Brian Jones]

Dan,

While you consider where to put your electric fan, you may want to  
read through this study by some Sunbeam enthusiasts. Over three  
summers they examined, measured, and repeated every aspect of their  
cars' cooling system, trying many things and settling on the few that  
they found actually made the difference. While their cars are slightly  
different, I think the lessons may be transferable to a Triumph. They  
reach a conclusion on electric fans, for example, that I would not  
have anticipated: pushers are best! Fans with few big blades move most  
air. Thin 'turbine' fans are to be avoided. The distance from the fan  
to the shroud was optimised, as was the distance from fan blade to  
shroud. The optimal measurements they report might help you.
