You can look up the formula for computing KE on the web and into the specs of your bow and arrow and find the exact KE of your setup.
I do have aset of 452x on the bow. I gained closed to 8 fps with that and the bow was crackerized as well. If you went to a 446 grain arrow. That would get me close to 252 fps if you lose 1 fps for every 3 grains of arrow weight increase.
