how come turbo's are praised when they give 4 strokes some of the same characteristics that 2 strokes are badmouthed for - lack of bottom end torque, lowered reliability, increased gas consumption. My Saab 9-3 is turbo charged with a very mild amount of boost, maybe 6-8lbs. At that level turbos have advantages, but when you start dialing in serious boost it becomes a grenade. I'd much rather have a 2 stroke.
There's some videos on youtube that show 4t singles that were turbo'd, not many though. You thought 450F's were unreliable and expensive without turbo, imagine with a turbo? You could easily double the horsepower though, if you can afford it..
By the way, lots of youtube videos showing turbo'd 2 strokes, especially snowmobiles ;-)
