We took a studded 2013 GSX LE and ran the 900 ACE TNT against it. We did did a staggered start of almost 2 sled lengths so you can see the difference. Being studded the E-Tec took it out of the whole and slowly pulled up to around 80+ mph when we shut it down. At the end of the run we had about 8 to 10 sled lenghts difference! While it may not quite be at the 120hp class level it certainly performs much better than it's rated 90hp.
It is also much smoother and quieter than the 600 ACE. In both engine and track noise! In my opinion if you are not a trail racer that needs 150+ hp and you really want a nice trail sled the 900 ACE in any fashion should be high on your list!
