Electric wheel guns

[FW17]

As per this video the air guns work at 450 psi, 16000 rpm, 3000-4000 lbs-ft

I guess the core issue is that they would need a sponsor. Why mandate a certain E wheelgun if you do not get money for it?

Was the double wheel de-attachment in the F2 feature race, due to the electric impact wrenches being overstressed with doing a double-stacked pitstop?

10s of running is practically nothing. Don't invent stuff.

Little comfort to Vesti!

Little relevance to Vesti.

So if the FIA thinks these pitstops are too fast and dangerous, electric wheelguns can be the solution.

How? You make them as fast as you want them... Besides it's trivial to make something like airguns slower.
Though I don't think the wheel gun speed matters much. More like the scrambling around.

Actually the video states they go up to 600 lbs·ft on the wheelnut.

Id dare bet that the air operated guns used in F1 are much faster than a battery operated one.

It would be all about the initial ramp of torque from the gun.

There is a good few videos on this channel: https://www.youtube.com/@TorqueTestChannel That show how the electric stuff ramps up. Granted I cant ever see them being able to get hold of a F1 air gun to test as be impossible.

I imagine its the instantaneous tightening levels that make the air guns desirable.

(I did watch the video FW17 linked after this post)

The air guns are pretty loud, even if you are sitting at the end of the straight. So they are pretty powerful I suspect.

When ive been to silverstone you can hear them testing the guns from the campsite.

You are completely right about the power. But where is the need for this speed? If they mandate a spec electric gun...then it is a fair game for everyone.

It’s a bit like the combustion engine Vs electric motor torque output.

A combustion engine needs some time to get up to speed, whereas a motor will deliver all available torque instantly and won’t drop off.

I imagine if you look at the torque ramp rate of a 1” Milwaukee impact gun and that of a 450psi air gun, the Milwaukee would come up in power at say 2seconds duration whereas a air operated one at mega PSI will be say 0.5seconds duration.

If you consider the ‘delay’ in reaching the torque of a electric gun vs air, you would easily have a extra pitstop in the delay of a battery gun getting the nut tight.

Just got to watch how many ‘Ugga dugga’s ‘ they keep the electric guns on for in the garage compared to when usi mg a air gun. Impacts per minute (and how hard it hits the anvil) will also play a part.

But why would I care if a pitstop takes 2 sec longer for every team?

Can you make them as fast as you want on a battery ? I thought about a battery based setup as we wanted to get rid of the wires.

I think F1TV described that at the Dutch GP where there is no space for a extra garage…. It effectively makes the pitlane longer and it plays out differently when the race is running.

I do not think it plays a role....simple comparison between Canada (lowest pitlane loss) vs. Monza (highest pitlane loss):
In Monza you see often different strategies. Last year nearly 50:50.
In Canada where the low time loss would support different strategies...you see 90% similar strategies.

Why do you want to make them faster?

You would in the best case get a wheel gun sponsor who sends tested and certified wheel guns to every team....stock as they are to save cost.

Cost doesn't matter under cost cap.
