It will all depend on how many turns total you can put on your limb bolts from mininum to peak weight. Bows vary some in this regard so it would vary on how much poundage you would gain as well.

Like said, the best way to do it is to measure it. The type of cams and draw length may even effect it a little.

I would not shoot for a specific draw weight though. I would set it to where it is comfortable and then measure the peak draw weight in order to pick the correct arrows. Knowing the draw weight of your bow and how fast it shoots has nothing to do with how well it or you will shoot. It only helps you track the tune of the bow (if it looses speed it is probably going out of tune) or lets you help pick the correct arrow spine.
