I don't exactlly recall what the IBO with smooth mods was for the ally.... but assuming it was in the 315 area, and assuming that you have about 10 grains added to the string in the form of a loop and peep, you'll have speed around 240-245fps.
Here is a link to a webpage that you can use to enter your set-ups information and get an approx arrow speed. In my experience its usually on the optimistic side by a few fps.... but it will give you an idea.
