Ya, it never really clicked for me until watching Gale Banks YouTube channel. He says it's Air Density that makes power. Boost is just the differential pressure from atmospheric to the manifold. So if a turbo is altitude compensating and you have a high pressure day how much is it really contributing. One could also say that it is robbing power by creating an exhaust restriction and warming up intake air temps slightly lowering the air density. Where the NA machine has no back pressure and more intake air density.Somedays the old NA feels better than others.
I had never considered a high pressure system though. Learned something today
With that being said MOST days snowmobiling at altitude won't be those conditions.
I'll also say since this is the cat thread I really think they have made good changes and since I prefer NA sleds I might have to snow check one for next year. I really want Cat to be a contender again.
