Kyle Larson wins at Phoenix, earns NASCAR Cup Series title

0 Comments

Kyle Larson completed one of the best seasons in NASCAR history by winning Sunday’s season finale at Phoenix Raceway to claim the 2021 NASCAR Cup Series championship.

An 11.8-second pit stop under caution from Larson’s No. 5 Hendrick Motorsports team gave him the lead entering the race’s final restart with 24 laps to go.

Larson did the rest, holding off fellow Championship 4 drivers Martin Truex Jr. (finished second), Denny Hamlin (finished third), and Chase Elliott (finished fifth).

Larson, who closes the season with 10 wins, becomes the 35th driver to win a title in NASCAR’s premier series.

He does so after spending much of the 2020 season indefinitely suspended by NASCAR following his use of a racial slur during an April 2020 e-sports event.

During that period, Larson spent time working to make amends and to mature personally. He also received a second chance to restart his NASCAR career when HMS signed him to be their driver of the revived No. 5 car.

Now, Larson has given the powerhouse organization its 14th Cup crown.

“I cannot believe it,” Larson told NBC Sports after the race. “I didn’t think I’d be racing a Cup car a year and a half ago, and to win the championship is crazy. … There were so many points of this race where I did not think that we were going to win.

“And without my pit crew on that last stop, we would not be standing right here. They’re the true winners of this race. They’re the true champions. I’m just blessed to be a part of this group. Every single person at Hendrick Motorsports – this win is for all of us and every one of you.

“This is unbelievable, I’m speechless.”

After winning the Cup title in 2017, Truex has now finished second in points for the third time in the last four seasons.

“’18, ’19, ’21 – three years, we were right there and had a car capable of winning, and just for whatever reason, it didn’t go the way we needed it to,” Truex told NBC Sports. “And at the end there, not quite enough speed to get to (Larson) and around him.

“I thought if he’d stay on the bottom a little bit longer, I’d have a shot. But he moved up and I couldn’t do anything on the bottom. It is what it is. They did a great job, they had a great season. Congrats to them. We’ll come back and try again next year.”

Stage 1 began with the Championship 4 drivers taking different strategies off early cautions. Larson pitted for tires on the day’s first yellow at Lap 8, but cycled back toward the front when Elliott, Hamlin, and Truex made their own first stops during a yellow at Lap 16.

Ryan Blaney stayed out under the latter caution and kept the lead for the next 30 or so laps. But on Lap 51, Truex passed him for the race lead. While Blaney faded out of the top five, Truex pulled away to the stage win ahead of Kevin Harvick, Elliott, Hamlin and Larson.

During the stage break, Elliott jumped two spots to take the race lead off pit road from Truex, whose jack man slipped on his stop but did well to recover.

As Stage 2 progressed, Truex’s long-run speed helped him reel Elliott in. Over 35 laps into the run, he reclaimed the race lead from Elliott at Lap 120. A Quin Houff crash brought out the yellow at Lap 130 and brought the leaders to the pits. Elliott again was first off to take the race lead, while Truex fell to fourth and Hamlin fell to ninth with slow stops.

Two more cautions for incidents led to another round of pit stops under a yellow at Lap 156. There, Larson came out first ahead of Elliott. Several cars stayed on the track, but during the ensuing restart, the entire Championship 4 were able to pass that group unscathed. Larson went on to win Stage 2 ahead of Elliott, Hamlin, Truex Jr. and Blaney.

Larson, Elliott, Hamlin and Truex Jr. kept their positions through pit stops during the stage break and the restart to begin the final stage. Elliott took the race lead back from Larson at Lap 236, as Hamlin in third began to close in with long-run speed of his own.

On Lap 245, Hamlin passed Larson for second and began working to catch Elliott. Three laps later, Truex was the first of the Championship 4 to visit pit road. As his car was serviced, Anthony Alfredo slammed the Turn 2 wall to bring out the yellow at Lap 249.

However, due to the timing of the yellow, Truex was able to stay on the lead lap. And with the other Championship 4 drivers pitting, Truex stayed out to cycle into the lead while Hamlin was first off pit road ahead of Elliott.

Truex and Ryan Blaney (who was also pitting when Alfredo crashed) led the field to green with 58 laps to go. When the field shook out, Truex and Hamlin were first and second, while Elliott and Larson were in third and fourth.

As the run went on, JGR’s long-run speed – now bolstered by track position – allowed Truex and Hamlin to pull away.

But with 30 laps to go, debris from the car of David Starr brought out the caution to set up the money stop for Larson’s No. 5 team – which in turn set up Larson for the exclamation point on a stellar season.

STAGE 1 WINNER: Martin Truex Jr.

STAGE 2 WINNER: Kyle Larson

WHO HAD A GOOD RACE: Ryan Blaney finished fourth to lead the non-Championship drivers … Fellow Team Penske driver Brad Keselowski finished 10th in his final start for the team before moving to Roush Fenway Racing.

WHO HAD A BAD RACE: Bubba Wallace was first out after contact from Corey LaJoie sent him into the Turn 3 wall on Lap 7. After climbing out of his car, Wallace sarcastically clapped for LaJoie as he drove by. … Flat tires led to crashes for Quin Houff (Lap 129), Ricky Stenhouse Jr. (Lap 140), Chase Briscoe (Lap 155) and Anthony Alfredo (Lap 248). Houff’s team, Starcom Racing, announced this week that its charter will have a new owner in 2022.

NOTABLE: Larson is the third driver in the modern era to win the Cup title in his first season with a new team.

NEXT: The 2022 NASCAR Cup Series season begins in earnest Feb. 6 with the exhibition Clash at the Los Angeles Memorial Coliseum. The first points-paying race of the season is the Daytona 500 on Feb. 20.

Harrison Burton looks for progress in second year in Cup

0 Comments

Harrison Burton made the first start of his NASCAR Cup Series partnership with the Wood Brothers in the bright lights of Los Angeles.

Burton and the Woods teamed last season as Burton jumped into full-time Cup racing after two full seasons (and four wins) in the Xfinity Series. Their first race was the Clash at the Coliseum, and it was a good start — Burton qualified for the feature and finished 12th on the lead lap.

Then things headed downhill. Crashes at Daytona and Auto Club Speedway left Burton with finishes of 39th and 33rd, respectively. After the first five races of the year, he had four finishes of 25th or worse.

Now, Season Two, and there are higher expectations. Much higher.

“The start of last year was really, really rough,” Burton told NBC Sports. “It kind of put us in a hole. We got into the wreck in the 500 and crashed at Fontana. Things kind of stack up on you, and all of a sudden you’re buried in points and it’s hard to make it back up.

“But, at the end of the year, three of the last four weekends were big for us (three consecutive top-20 finishes). We need to build off that and try to get out of the West Coast swing and have a clean group of those races. That’s really important. We need to get our average finish up in the first four to five races and not put ourselves in a hole we can’t get out of, and then go from there.”

The Wood Brothers team typically brings strong cars to the Daytona 500, the season’s first point race. Trevor Bayne scored the team’s latest win in stock car racing’s biggest event in 2011.

“We ran well in the 500 last year until I was upside down,” Burton said. “We had a fast car and qualified well and finished third in our duel. Then in the second Daytona race we put ourselves in good position late, so we were in contention in both Daytona races. The speed was there, and the cars drove well.”

The team’s primary goal is to make the playoffs, Burton said. “And we want to be a contender,” he said. “Cup races are so hard. First, you have to contend. Having a good average finish is really important. If you average around 17th or 18th all year, you can kind of point your way into the playoffs, and doing that is on our minds for sure.”

Burton looks for a strong start in Sunday’s Clash, which will present teams with a mix of the old and the new. Drivers got the experience of racing inside the Los Angeles Memorial Coliseum last year, and notes from that race will be useful, but the racing surface will be all new again.

“Every repave has a different tendency,” Burton said. “We’ll see how close it is to last time and how different. Obviously, there is experience on that track, but still it’s a completely new surface, so it’s going to be a mixture of old and new. There’s some knowledge we can build off of, but we kind of have to go into the weekend with that knowledge as tentative because we don’t know if the track is going to be different.”

Burton heads for Los Angeles with a win already under his belt this year. He and teammate Zane Smith, last year’s NASCAR Craftsman Truck Series champion, won last Friday’s International Motor Sports Association’s Michelin Pilot Challenge Series race on the Daytona International Speedway road course.

Burton drove the finishing laps in the four-hour race. He was third with about 50 minutes to go but moved in front with 22 minutes left when leader Elliott Skeer parked. Burton outran second-place Spencer Pumpelly by .688 of a second for the win.

“I thought we could run well,” Burton said. “After the test we did, we were really fast, so I was pretty excited. But apparently there is a lot of sandbagging that goes on there, so I wasn’t sure where we were. We had to have some things go right for us, and they did.”

 

 

 

 

Dr. Diandra: Muffling racecars won’t change fan experience

0 Comments

Last week, NASCAR tested the muffler that will be used for Sunday’s Clash at the Coliseum.

“Heresy,” some fans cried. They argued that it is against the laws of man and nature to muffle racecars. That noise is an integral part of the fan experience. That you’re not supposed to be able to have conversations during races.

Relax.

The cars will be plenty loud.

Loud is fast

Engines produce power by combusting fuel and air in their cylinders. Each combustion produces high-pressure gases that push the piston up. The same gases make a loud popping sound when they escape the cylinder and finally the exhaust.

At 8,000 rpm, an eight-cylinder engine performs about 520 combustions every second. The faster an engine runs, the more combustions per second and the higher the frequency of the tailpipe noise.

That’s why NASCAR engines sound like grizzly bears and F1 engines, which run at higher speeds, sound more like angry mosquitoes.

Maximum horsepower requires getting the spent gases out of the cylinder as quickly as possible so the next combustion reaction can start. And that’s the problem with mufflers, from a racing perspective.

Mufflers on street cars bounce sound waves from the engine around a metal can. The waves interfere with each other, which decreases the overall volume coming from the exhaust.

Mufflers can also mitigate noise by directing the exhaust through a sound-absorbing material. Borla, the sole-source supplier for this weekend’s muffler, makes commercial racing mufflers that feature a robust sound-absorbing material superior to the commonly used fiberglass.

Both methods slow the exhaust gases — the first more than the second. The ideal racing muffler diminishes sound with minimal horsepower reduction.

Decibels

Sound-level measurements come in decibels (dB), a unit named after Alexander Graham, not Christopher — and apparently by someone who wasn’t the best speller.

But decibels don’t tell the whole story. Sound intensity decreases with distance, so you need to specify how far away the sound source was.

The easiest way to explain the decibel scale is to relate it to real-world noises, as I’ve done below.

A bar chart showing representative sound levels expressed in decibels.

  • Zero dB is the threshold of human hearing.
  • A whisper you can just barely make out is about 20 dB.
  • Most everyday noises are in the 60 dB to 100 dB range but are sometimes louder.
  • Exposure to 130 dBs can be painful.
  • A 150-dB sound can cause permanent hearing damage in a very short time.

Ringing in your ears the day after a rock concert was a badge of honor in high school. Older me wishes I had been a little smarter.

Hair cells — not to be confused with ear hair — facilitate hearing. Sound bends these hair-shaped cells, and the cells convert sound into electrical signals that the brain interprets. Loud sounds can bend these cells so much that they break.

Unlike animals such as sharks, zebrafish — and even the lowly chicken — humans cannot grow new hair cells. Once your hearing is damaged, you can’t get it back.

How loud are racecars?

A noise mitigation study for the proposed Nashville Fairgrounds track measured a single Next Gen car at COTA generating 112 dB on a straightaway at 100 feet.

A 2008 study measured the sound level inside a Gen-6 car to be an average of 114 dB. The study also compared sound in the stands, the infield and the pits.

Let’s add those numbers to our graph.

A bar chart showing representative sound levels expressed in decibels, including sound measurements from the Gen-6 and Next Gen cars

  • The Next Gen car at 100 feet is about the same loudness as a person screaming at top volume 1 inch from your ear.
  • The Next Gen car at 100 feet is just a bit quieter than sitting inside the Gen-6 car.
  • Bristol reached peak sound levels loud enough to cause permanent hearing damage.

The graph data suggests that inside the Next Gen car should be around 10 times louder than inside the Gen-6. Some drivers made new earmolds to cope with the additional noise in the cockpit.

Because of the way sound works, the numbers don’t add like you’d expect them to. A Next Gen car might be 112 dB, but two Next Gen cars are more like 115 dB. A full field would be only 5-7 dB louder.

The mufflers won’t muffle much

NASCAR expects a six to 10-dB reduction in sound with mufflers. A 10-dB reduction would make the Next Gen car about as loud as the Gen-6 car was.

Another way of looking at it: Good earplugs reduce sound levels by 25 to 30 dB. Wearing earplugs just barely gets you into the range of being able to hold a conversation if you stand very close to each other and you both shout.

You won’t notice the change in sound inside the track.

You also won’t notice a change in speed this weekend, despite a drop of 30-40 horsepower. The Next Gen car takes around 14 seconds to traverse the L.A. Coliseum’s quarter-mile track. That means cars won’t be going much faster than typical expressway speeds.

If you’re headed out to the track this weekend — despite the mufflers — bring earplugs or over-the-ear headsets. This is especially important for children, as their hearing is more easily damaged.

Joe Gibbs Racing adds young racers to Xfinity program

0 Comments

Connor Mosack, 23, and Joe Graf Jr., 24, each will drive select races in the No. 19 Xfinity Series car for Joe Gibbs Racing this season.

Mosack, who has a 20-race Xfinity schedule with Sam Hunt Racing this year, will run three races for JGR: Chicago street course (July 1), Pocono (July 22) and Road America (July 29) while also competing in six ARCA Menards Series races for JGR, including Feb. 18 at Daytona.

Graf, who has a 28-race Xfinity schedule with RSS Racing this year, will run five races in the No. 19 Xfinity car for JGR: Auto Club Speedway (Feb. 25), Las Vegas (March 4), Richmond (April 1), New Hampshire (July 15) and Kansas (Sept. 9).

“I made my Xfinity Series debut with JGR last June at Portland and from the moment I made my first lap in their racecar, I realized why they’ve been so successful,” Mosack said in a statement. “Their equipment was second to none and the resources they had in terms of people and their knowledge was incredible.

“Jason Ratcliff was my crew chief at Portland and he’s got a ton of experience. I was able to learn from him before we even went to the track. Just in our time in the simulator, we made some great changes. So, to be back with him for three Xfinity races is going to be really valuable.

“And when it comes to JGR’s ARCA program, it’s the class of the field. After having to race against JGR cars, I’m really looking forward to racing with a JGR car. No matter what track they were on, they were always up front competing for wins. To have that chance in 2023 is pretty special, and I aim to make the most of it.”

Said Graf in a statement about his opportunity with JGR: “Running five races with JGR is a fantastic opportunity for myself and for my marketing partners. I think I can learn a lot from JGR and showcase my skills I’ve been growing in the series in the past three years. 2023 is shaping up to be a great year and I’m pumped to get started with the No. 19 group.”

Ryan Truex has previously been announced as the driver of the No. 19 Xfinity Series car in six races this season for JGR. The remaining drivers for the car will be announced at a later date.

Mosack didn’t start racing until he was 18 years old. He went on to win five Legends car championships before moving to Late Model stock cars in 2019. He graduated from High Point University in 2021 with a degree in business entrepreneurship. Mosack’s first Xfinity Series race with Sam Hunt Racing this season will be March 11 at Phoenix Raceway.
