–A lottery system will determine how the guns randomly are issued before the race (this is similar to how NASCAR distributes its restrictor plates for race at Daytona International Speedway). The guns will be returned within an hour after the race.
–Pit crews will be limited in modifying the pit guns. The socket can’t be removed, but there are some adjustments allowed with grip tape and screws. Certain parts of the gun will be sealed to detect tampering.
–Air pressures for the guns will be mandated by NASCAR, and the pressure relief valve will be set by a digital gauge.
–Teams will be provided with three guns that are labeled as front, rear and spare.
–The guns will be tested regularly to ensure their consistency. |
That sounds a bit restrictive for teams to develop a competitive advantage during pit stops
When F1 went from fuel to no fuel pit stops I was responsible for the mechanical design of everything used in a pit stop for one of the top teams.
Guns were one area we really concentrated on, it would take very few impacts and 2.5 turns to put the nut on, We measured the number impacts with a strain gauged titanium socket and had a light to let the mechanic know when the nut was tightened.
We lightened the gun weight using carbon fibre parts, upped the preformance with low friction larger impellers, seals and ceramic bearings and wound the air pressure up until we started breaking the mechanics
This manufacturer was our weapon of choice

Pit stop time went from 4.2 secs to 2.5 secs, now its around 2 secs
I'd love to work on a NASCAR as I'm sure there is a high level of detail needed when trying to eek out the last bit of performance. Anyone know a NASCAR team that needs some help please send them my way.
