911 Cooling Shrouds - Improving Internal Air Distribution

[Typ Vier]

Cheers Clive,

Understand your point and you are probably right but that would mean you would have to space the idler pulleys further apart. There could be clearance issues with the distributor, possibly requires a larger bottom pulley and of course a longer belt. Larger idler pulleys could be beneficial. Would be interresting to see how it works, although probably not as compact. But then again, getting 20.000 Km's out of the belt as it is in this configuration is good enough for me

I agree it would not look so elegant and certainly the wider idler pulleys might be in the way since to get any real improvement they would have to be engine width apart? Alternatively, you could substitute a bevel gear for the engine
pulley and then you would only need a pair of horizontal pulleys.......................... And then onto theoretical Physics..
