Sport Science explores the science of a NASCAR pit crew, Part 1

the ultra-competitive world of NASCAR the difference between winning and losing often comes down to fractions of seconds that means victories aren't always determined behind the wheel Kyle Busch wins that are they can be won or lost in the pits for the first time ever we're gonna look at the anatomy of the perfect pit stop fasten your seat belt because these are some of the most pressure-packed seconds in all of sports to analyze the perfect pit stop we packed out the sport science lab and travel to the Joe Gibbs Racing headquarters in North Carolina where we recruited one of the most dominant pit teams in all of NASCAR the crew for number 18 Kyle Busch in 2008 this all-star pit crew helped Kyle set a record for most wins in a NASCAR season the picker is real important waiting races you got to have a strong pick room to be able to get you off pit road without losing spots because nowaday with this car that we have you can't really pass that well nowadays the guys in the pits aren't your average grease monkeys they've evolved into finely tuned athletes plucked from the ranks of elite college sports and they prepare for races like a team in any other professional sport and here in the back of Joe Gibbs headquarters Kyle Busch's seven-man team the jack man the gas man the catch-can man the tire carriers and the tire changers will help us break down one of the fastest pit stops in NASCAR the perfect pitstop starts with the gas man dumping 12 gallons of fuel from his 90 pound tank in about five seconds the Jackman has a split second to position the 35 pound jack underneath the cars three-quarter inch Jeff ho and like an elite quarterback the Jackman has to anticipate his teammates moves before he drops the jack if a Jackman drops the car too soon before his teammates are done the driver can speed away with a loose tire easily costing a race basically a pit stop is choreographed chaos it looks like well there's a lot of people running around the cars Ren you've got hoses and tires and fuel but it's very very precise while each job in a pit crew is crucial the position with the most pressure is the tire changer our phantom high-speed camera reveals never-before-seen details a front tire changer Nico Dells skill and athleticism Nick takes only one and a half seconds to lengthen the wall into position but what makes Nick the star of the pit crew is that he can remove five lug nuts in one second hundred milliseconds per lug not each lug nut spins a stunning ten revolutions per second twice as fast as a helicopter blade and the high-speed footage reveals that amazingly nick has already moved on to the next lug nut while the previous one is still spinning off after the tire goes on Nick accelerates off the ground laterally with four G's almost two times as much force as his driver feels going around a turn at 200 miles per hour with no wasted motion getting around the car nick hits the ground and gets to work on the other tire if Nick and his teammates do their jobs perfectly it all adds up to a blazing 12 point one two seconds and if you break it down to its finest details this seven-man team must execute a mind-blowing 73 unique maneuvers in less than 13 seconds but a day standards it has to be 13 seconds flat or better the guys who can do that 8 9 10 out of 10 times they're gonna want it be in the winners for the day if you compare a pit-stop to other plays in sports like James Harrison's 100-yard interception return in the 2009 Super Bowl a perfect pit stop is actually faster to get some perspective on just how difficult it is to get a car back on the track in no time flat we recruited a former legend in the pits NASCAR announcer Jeff Hammond Jeff was the jack man for Cale Yarborough's three Winston Cup seasons and later won two more championships as the crew chief for Darrell Waltrip what would happen if you were part of the team if you'd asked me this question about 15 years ago I'd say nothing got me I'm a pretty good jack man I'm not much of a tire changer but today Jeff's going to pull out his old gear and work alongside other members of Kyle Busch's team changing tires can this Pitt veteran keep up with today's elite crew and help them beat 13 seconds find out when sports science continues I don't know where the throw up I run hide behind this wall because I don't know what's gonna happen

  1. The cool shots of the lugs flying off 👍, but where do the new lugs come in to play? Don't think they kept track of the ones that flew off, so there were replacements? How do they start them, by hand.

  2. Why do nascars use multiple bolts to hold a wheel on. You know pit stops would br alot faster if you have single center hub bolts holding the wheel on. Not very perfect of a pitstop. Just another reason to prefer v8 supercars

  3. I don't wanna be that guy, but if we compare it to other pit stops in other motor sports, I think F1 is just a bit faster… just a tiny bit…

  4. Hang on.. with type changing if the nuts comes the 1st time and when u put the new type on where are the nuts

  5. nascars kinda dumb its just 50 cars racing in circles go watch some f1 or something cause it actually has some cool things in it
