Torque sticks?????

[JohnRW]

As Matt noted, it's actually very easy to create a "calibration sheet" for an air impact gun. For example, I know that my Ingersoll 1/2" gun will, at 80psi on the regulator and using a 50' length of 1/2" hose, reliably hit 75 ft. lbs. Need a little more or less...just fiddle with pressure a bit.

That said, we ALWAYS follow up with a torque wrench. You're nuts if you don't.

That's an interesting point. Watch any ALMS race, or Koni race, and the guy with the gun zings them on, and off they go. I can't ever remember seeing a guy run around with a tq wrench...

Truthfully, it matters what your intentions are. If you are trying to win a race at all costs, just bang them on and don't be afraid of over torquing them. Expect to change studs after the race.
If you don't want to replace your studs, take more time going on with them. I personally use a torque stick and have never had a problem with it, but make sure nobody tries to use it in reverse.

changed tires around 40 to 50 times on a ST team, never once changed/broke/needed to replace a stud.

Same goes for other enduros I have worked.

After a while you get a really good feel, with Air it more sure fired, but even with a electric impact you can get a good feel for it.

Right, what I meant to say was, if you are going for all out performance, pound them on quickly and deal with breakage afterwards. You probably won't need to change anything, but you could and if you did, it would be studs.

No pun intended...............
