How much speed do you gain per pound of draw?

It varies greatly bow to bow, but 3-7 can be expected.

Thanks I always wandered that! I shot the General at 65# and was getting 284FPS but I will be shooting 70# when my new one arrives so I should be around 300FPS then. Thanks again I always wandered.

not neccessarly - different bows have different velocities. A lot of this is due to design (cams, limbs, etc.) Your new bow at 70# may not shoot as fast as your current one set at 65#. If both are the same model, it should be faster. But we are only talking approx 25 fps more average.
Don't get too hyped up on speed. A super fast but erratic shooting bow has no advantage over a slower more accurate one. It just means you'll miss faster.

3-7 sounds pretty excessive. The norm is about 2 fps per pound of draw., either up or down depending on which way you turn the limb bolts. Bows vary from model to model, but not that much.

I have to agree!! Most testing I have done showed an average gain of 2.5 fps per pound increase in draw weight. I've never tested a bow that was any where near a 7fps gain

Thanks guys! What I meant to say is the general I had set up to shoot was 65# and now that I ordered one it will be a 70# when I was shooting the easton lightspeed arrows I was getting 284FPS so I should jump to mid 290's thats all I wanted to know! Thanks again!

I shoot an XI legacy at 80# with a 3.5 inch overdraw 100 grain muzzy with 26 inch carbon express arrows and get about 305 out of it.

What's the total weight of your arrow?

You know, I first read this reply and laughed......I said ONLY 2??? Then I thought about it aminute........I was thinking of 1 turn of the limb bolts, not 1 pound per draw weight.....I stand corrected.......2-3 is more accurate. Mobow's bad.
