My average ball speed is 167mph and the highest i can seem to get it too is 173mph what would my average ball speed be in relation to club head speed mph? Does anybody know this

I thought somebody might know this?

You can determine this by using the smash factor ratio which is typically between 1.25 and 1.5. It is the ratio of ball speed to clubhead speed. Example: If your driver is at the .830 COR, the smash factor is 1.49. If your ball speed is 167mph, your clubhead speed would be about 112mph.

The smash factor will vary with drivers. For my SQ it was 1.47. My ball speed was 175mph, swing speed 119mph. If you got your ball speed from a launch monitor, you should have gotten your swing speed as well.

is there a chart for this?

There is a chart relating COR to smash factor. I will try to post it or a link to it for you.
