I think a turbo would be the way to go. There is a KX500 Turbo with a kit on it on youtube somewhere I have watched. I just dont know if buying the Arctic Cat is a good idea with a Sherco 450. Dealer network would not be good for a while and if Arctic Cat thinks it can handle that and be profitable in this line, I think they may be making a mistake. It will be fun to see.
Corbin, how did your 300 KTM compare to your dads 450 Berg with the kit on it?
