I can't see a practical way for me to get a duct to the windscreen, that's why I'm going up front. Still need to do some checks and see what sort of vacuum is present post air filter, it may be that under cruise conditions by using ram air it may just get the preturbo pressure up to atmospheric.
The other thing that I am considering is when coasting down it may be beneficial to restrict the ram air so the engine is not just pumping air needlessly and loosing the benefits of a downhill coast.

Yeah, the front of the vehicle would also be easier, since you don't have to worry about interacting with opening & closing the hood.
