What kind of impact wrench does nascar use

The modifying started when Glen and Leonard Wood of the Wood Brothers Racing team asked Howard if he could start supplying them with tweaked versions of the wrench. Back then, pitstops were slow-paced affairs—almost leisurely compared with today's standards. With souped-up tools and a rigorous pitstop ethic, the Wood brothers dominated. Soon pitstops became pivotal and Howard was in high demand. Jim Hurd proudly carries on his grandfather's legacy. He's in his 28th year on the job and currently services the Thunder Gun, which was launched by Ingersoll Rand in with the help of Ray Evernham, Jeff Gordon's crew chief at the time.

The guns are used by nearly all Nascar tire changers and can be modified in numerous ways. For example: Nose cones can be steel, titanium, or carbon fiber the last being the lightest. The gun's exhaust can be widened for improved airflow and higher rpm, and it can even be repositioned if needed a front exhaust might blow brake dust in the gunman's face, or a side exhaust could spit oil onto the jackman or the tire carrier.

And the resistance on a forward—reverse torque toggle can be adjusted most Sprint Cup tire changers prefer high resistance to prevent an accidental switch. Back at the hauler, people drop in just to say hi, and Hurd seems to know everyone around the garages by name. This could soon change, though. The tire compound is the material the tire is made from — a softer compound can provide more grip but wears faster, while a harder compound will last longer.

Each track causes tires to wear differently, and the inside tires wear differently than the outside tires. Race cars use tires without tread because smooth tires provide better traction in dry conditions.

Otherwise, water will come between the tire and road surface, causing the driver to lose traction and hydroplane. How fast do pit crew change tires? What happens during a pit stop? What is pit stop?
