2012 Regulations - Teams already finding loopholes

2012 Regulations - Teams already finding loopholes
Look at the pic of Mercedes from new driver test day

Exhaust is already pointing across the upper wing elements and they are measuring flow or temperature along the bodywork - the green strips of stuck on sensors

Bet you that Newey has the exhaust running down to the floor and under the lower wing element creating a secondary diffuser

I doubt it.

From 2012, pipes will have to extend to between 330-350mm beyond the rear wheel centre line, will have to be in a space between the lower rear wing and top of the diffuser and will need to be circular in dimensions, with a vertical cut-off.

I just fell over this. Never knew they were even doing such crazy stuff.

For 2012 the use of helium in air guns used to change tyres during pit stops was banned. Despite increasing the rotation speed of the air guns by up to 30%, the use of helium was deemed to be too expensive with little competitive gain.

Anyone know why the use of Helium in an air gun would make it rotate 30% faster ?

Lower density gas will pass through the gun quicker. That's my guess.

RE: 2012 Regulations - Teams already finding loopholes
i've been thinking about this all day, and i'm mystified. it seems to me that any gains you'd get from the lower density gas being more compressible or faster-flowing would be negated at the other end by having less inertia when it comes time to use the momentum to torque the wheel nut. though physics is not an area of expertise for me, so what do i know?

how much torque do they put on the wheel nuts? maybe they're not very tight, so the speed would be more important than the power.

I don't think density powers it, the pump in the gun will use pressure differential to get it's power. The exhaust of spent gas will take power out so a low density gas will exhaust quicker.

It seems bizzare that they would do this when if they wanted 30% more speed they just goto the manufacturer of the gun and get one, or use a coarser thread or something. Helium is relatively expensive and resource limited, we are about to run out of the stuff.

Are the wheel guns standard equipment mandated by the FIA?

That's probably it, so the only way they can alter performance is by changing the gas.

The only reference I can find in the sporting regs is

12.8.4 - Powered devices which assist in the fitting or removal of wheel fasteners may only be powered by compressed gas.

Do Nascar still have 4 or 5 lug nuts and they have to be done up by hand with a 4 arm wheel brace?

So they are allowed air guns, Good Ole Boy Style.

supposedly, they're getting some wondrous new technology called fuel injection next year, but i'm skeptical because they've been saying that for over a decade.
