I shoot the Alien X 70lb Limbs. I was researching noise issues and decided to check the timing again. I found the timing to be slightly off and wow what a difference it made in reducing noise. I shot it right next to a top of line Darton and my Alien was just as quiet. I have no limb dampners, no string silencers, and only a STAB to help reduce shock/noise.
I am pulling 28" draw with release, I am shooting 63lbs draw and before the timing change was hitting 294 with 354gr arrow. After the change we chronographed again at 309/310 FPS...
QUESTION: Why such a huge change in speed when the timing was only very slightly off? Also, how does improper timing create noise?
