I put the RSD Turbine on my '12 FLHXSE3. I like the looks of it better than the HD Ventilator by far, but there are a couple things to consider.
It won't improve the performance over the stock Ventilator.
It sticks out further than the Ventilator, and extends into your knee space a bit. Not as bad as the new HD ACs like the Agitator and Chisel.
It depends on the model of CVO you're going to put it on. On my SG, there's no other black or brushed aluminum finishes, so the Turbine looks a little out of place. The chrome unit might look better on bikes with lots of chrome like mine. On the models with more black parts (like the '11 SGs and the '12 RGs), the Turbine looks awesome.
I'll try to post a couple pics
