I have a video fully demonstrating the points I made above, but unfortunately, it'* 70mb, and for some odd reason, I don't have Microsoft Move Maker on my new laptop. I'll get it trimmed down and uploaded tomorrow at work when I have access to my workstation.

This is a 1/2" Husky impact wrench. 500ft/lb forward, 600ft/lb reverse.

Wow, no harsh impact whatsoever. You are correct though, with the rotors already spinning, there is no slam on anything, so it really won't hurt anything. I have to keep this in mind when I drop pulley sizes! Thanks.

There are many impacts there. The coupler and rotor gearing take the brunt of it.

Thank you for the video and explaination that care should be used with the impact gun.

There were no DAMAGING impacts there, even with the Impact gun set to it'* highest setting, and my regulator set to 140psi.

I don't normally do it at that extreme level, but to prove my point, I demonstrated that the 'worst case' still won't damage any part of the charger. And I did this on the next Supercharger to go on the Zilla this winter, with zero hesitation.

The rotors TURN, thereby preventing impact damage. Let me remind everyone.....I've done ALOT of pulley swapping like this on both cars for quite some time. I've never seen ANY damage to couplers, bearings, or gears. In fact, I don't think anyone on this Forum can even begin to claim to have swapped more Series 1 pulleys than me. And I do every single one of them like this so that I don't have to hold (and possibly damage) the pulley.

At this point I'd like to challenge someone to try to PROVE that it WILL damage something. My experience points to the contrary.

I love videos like this.

I agree with Bill, there is no way this could damage anything. Unless the rotors are frozen solid, then of course the coupler would snap.. but at that point.....
