i have a short draw length so i only get about 230fps.that dont bother me as i worry about shot placement more.but k-energy is only around 38. bow is at 55 and im going to go to the 60 pound max on it. will this help my k-energy an if so anyone got any idea how much it might help?[&o]

KE = speed x speed x arrow weight divided by 450240. So by increasing your poundage by 5 pounds you are going to increase your speed a little which will help some. But there is not much you can do besides buy a new bow.

It will increase some depending on what bow you shoot and how much your arrows weigh but don't worry too much about it. Just put the arrow where it needs to be.

What I would be worrying about would be useing a sharp broadhead like a two blade stinger or steel force for maximum penetration. Then go kill your deer or elk or moose.

Ditto what bigbulls said, get a more efficient broadhead design. I shoot and can honestly recommend the Stingers from Magnus. Fly very, very well, sharp out of the pack and lifetime guarantee. You could shoot at rocks for practice and they will replace them.

Are you sure on your KE? 38# seems awful low to me. Do you happen to know what your arrows weigh?

From the formula the arrow weight would be 323 grains.
