Electric wheel guns

[mzso]

So it really serves no purpose moving to a electric gun and taking 5-10seconds longer to remove and retighten the wheel nut.

I do not know where you get your numbers from...but:
In the F2 race highlights from Zandvoort (Youtube) you can see performance pitstops with electric guns. If you look at races from last year you can see stops with pneumatic guns.

I can barely count a difference in time. With the fact that these are spec nuts and long threads....not extra short F1 threads...

So I would rather say we are talking about 0.5-1sec...

I don't see any good footage, only of the botched pit stop, with others you don't get a decent look.
By the way, is there some good footage of F2 pit stops with a good view of the impact wrenches in action? With all this talk no-one actually shared any.
