2014 plus grizzly vs 2012 grizzly 700 jbs sheave

Are the new grizzlies that much faster that I couldn’t win in a drag race? We haven’t raced yet but his 2014 has beaten my brothers honda 700xx, just wondering g what to expect. I’m running 26 zillas and he’s all stock. Love my bike anyways its been awesome and feels like it rips, just wondering how much improvement there is in the 2014 plus.
