I just spoke to Milwaukee HD and asked them whether it makes a difference where the air would be sucked in from and would this make a difference, i.e., front, rear, close to the engine ect. Their answer was fundamentally no. Now looking at all the different bikes there are, there would be some small temperature differences potentially (which was a question I had) depending on some variables. Would that make a difference?
Differences would be a bagger with lowers vs. a bike without them. Most likely it would seem that there would be a temp difference but given the fact that when you're riding and air is passing over the engine the temp difference would be negligible. The same might be said for whether the air is coming from the back, side, front or 3 inches forward. The HD tech said, "Since you're not racing for money on a track trying to squeeze 2 10ths more of a second of time, the real question is what look you're going for?"
All engines run hot and you're going to be sucking in hotter air than what's flowing over your head. The only real difference is if you get a "heavy breather" capable of taking in much more air. He said air temperature has very little to do with the performance rather than the amount of air being consumed by the engine during typical riding conditions that we mostly experience.
His further recommendation was for that of the HD tuner and dyno time. Now I know that everyone will have an opinion about this and the information I got is coming from that very man who will be taking my check (so I can pick up my bike), but it made sense to me.
