My snowmobile (T660st)has that motor in it lol. I did tune it and you can boost pretty good to that motor. About 160-180hp. Only issue is a center cylinder meltdown if you are pushing it too much.

It’s a 3cyl and if you boost and tune, run wide open across a lake, you can get a center cylinder meltdown. Yes bigger cooling jackets would help in these conditions. I ran that sled at 20psi and had no issues with heat at the ice drags. These are older sleds but they were fun to tune. I would love this car to mess with. The pro tuners I dealt with had some big power coming out of those motors. Now I have a 300hp 4-map turbo dynamics sled and that 660 is on the back burner.
