Do you really even need the shroud?

I was thinking that but there is a good size gap between the mechanical fan and the radiator.

The Taurus fan flows about the same CFM as my Zirgo. My fan will only run in bumper to bumper traffic on 90+ degree day. When it does its only for a bout 5 min at a time.

Thanks for the info.

My guess is once everything is hooked up that the fan will barely run - but will be there when it is needed.

On a TDI, 10 to 20 seconds at a time.

You need a shroud. Without a shroud, you are losing most of a fan's flow.

Thanks again Red - I will just move ahead with the electric setup. Too many small things on my build so I have been a scatter brain.

Hi chaps, what about the intercooler?
Even on idle the mech fan is drawing air across the intercooler which will be lowering the temp of the air charge.
something to think about..

That's interesting ... But is any power gain greater than the additional load on the alternator ( from running the fan ) and hence drain on the engine? If it is you have invented a perpetual motion machine and I'll need you to sign this licensing agreement. :-)

Realized I misread gren's comment. Thought he said electric fan.

The stock 200 shroud restricts flow through the intercooler.
