Hi Paul,
I did the smoothing out of the inlet all the way to the radiator.
I also included a cooling flap at the outlet of the duct. If you are
doing the factory thing, make sure that NO air get around the oil and
water radiators. The air will go to the path of least resistance. Use
the rubber fabric if necessary to blank off areas where the air will go.
I went the unique way and redid the cooling system. I have a separate
oil cooling radiator (original Europa cooler) that has its own duct
inlet. The main large duct is only for the water radiator. It works
very well for my 912 S. I also have some pix if you want to see them.
