Breaking down the Xfinity playoff field ahead of Texas

0 Comments

The Xfinity Series underwent a change in its playoff standings last week without the series even holding a race.

Daniel Hemric exited the Round of 8 opener at Kansas with a nine-point lead over Elliott Sadler. Then NASCAR handed Hemric a 10-point penalty and suspended his crew chief for one race after his No. 21 Chevrolet was found to be too low in post-race inspection.

After an off week, Hemric is second on the playoff grid, one point behind Sadler ahead of this weekend’s race at Texas Motor Speedway (4:30 p.m. ET Saturday on NBCSN).

That points shift came after a major shakeup on the very first lap of the Kansas race. A multi-car wreck involved playoff drivers Christopher Bell, Justin Allgaier, Austin Cindric and Cole Custer. Only Custer was able to finish the race.

The playoff field is separated by 56 points.

Here’s a look at the eight playoff drivers ahead of the series’ trip to the Lone Star State.

Elliott Sadler ( 14 points above cut line)

Sadler, who is winless so far in his final NASCAR season, leads all drivers with seven top-10 finishes in the eight races on 1.5 mile tracks in 2018.

His best finish on a 1.5-mile track this year is third at Kansas. He’s placed fifth three times.

He’s finished in the top six in seven of the last 10 races of 2018.

Sadler has just one top five in his last 14 Xfinity starts at Texas.

“Being able to head to Texas in our current points position gives us some relief, but we still need to go out there and give it our all,” Sadler said in a media release. “As we saw in Kansas, anything can happen in these playoff races. We still have a long way to go to get to Homestead and these next two races are crucial in making the championship four.”

Daniel Hemric (+13 above cut line)

Like Sadler, Hemric is winless through 30 races. But he’s finished in the top 10 in each of the four playoff races.

He leads the playoff drivers with an average finish of 5.5 through the playoff races, up from a regular season average of 9.9. His average is 2.5 positions better than any other playoff driver.

Hemric finished third at Texas in the spring and has four top fives on 1.5-mile tracks this season, fourth among playoff drivers.

“The guys that entered the Round of 8 with a solid points advantage thought they could cruise all the way to Homestead, well, we proved that theory wrong in the opening laps of the race at Kansas Speedway,” Hemric said in a media release. “Now everyone has to legitimately race every single lap and try to get to the end of these races in order to score points and at least get an opportunity to advance. It is no different than what we have been doing all year. We need to maximize our days and maximize the weekends.”

Tyler Reddick (+11)

Reddick is winless since he won the season opener at Daytona, but the JR Motorsports driver has finished in the top 10 in six of the last nine races, including a runner-up result at Indianapolis. He has top 10s in three of the four playoff races

Reddick will make his third start at Texas. He placed 33rd and 23rd in the first two. In the spring he was caught speeding after he pitted from third place on Lap 136.

“We had some good speed here in the spring and I am very confident that we can back that up and unload with that same speed this weekend,” Reddick said in a media release. “With our position in the Round of 8 right now, we all know what we need to do and if we can have a smooth, mistake-free weekend we should be able to leave here in an even stronger points position as Homestead approaches.”

Christopher Bell (+1)

Before he crashed on Lap 1 at Kansas, Bell was riding high through the playoffs with three top fives and two wins in the first round.

Now he’s hanging by a thread above the cut line.

The rookie returns to Texas where he finished second in the spring, one of six top fives he has this year on 1.5-mile tracks.

Though he has two victories in the playoffs, he’s only won two of the last 15 stages.

Matt Tifft (-1)

When it comes to average finish among the playoff drivers, Tifft has had the biggest improvement from the regular season. Through four playoff races his average is eighth, up six spots from his regular-season average.

He’s finished in the top 10 in eight of the last 10 races.

Tifft finished sixth at Texas in the spring. His four top 10s there are tied with Dover for his most at a track.

“Since they’ve paved Texas, it’s a lot more similar to Kentucky, where it’s a one to one-and-a-half lane track,” Tifft said in a media release. “It’s very narrow at Texas. Usually at intermediate tracks we have big, sweeping wide arcs. … The challenge with Texas is we run such a hard tire that we’re pushing the car to make it as free as possible, but there really is no slip in that tire so if you push it too far you’re done.”

Justin Allgaier (-5)

The JR Motorsports veteran was on a hot streak entering the playoffs with three wins in the last six regular-season races.

But Allgaier’s fortunes have cratered since then. He crashed at Richmond and Kansas and placed 15th on the Charlotte Roval. His only positive was placing third at Dover where he won in the spring.

After an average finish of 8.7 in the regular season, his playoff average is 22nd.

Allgaier doesn’t have much to look forward to with Texas, where he has just one top-10 finish in 16 career starts. He placed 35th in the spring after his engine expired.

“Kansas definitely didn’t go the way we wanted it to and that’s on me,” Allgaier said in a media release. “We find ourselves in a hole going into these final two races in the Round of 8, but one thing is for sure, whenever this team has been down we’ve come back stronger than before. I have faith that we can finish strong this weekend and head to Phoenix with a solid shot at making it to (Miami) as part of the championship four.”

Cole Custer (-23)

The Stewart-Haas Racing driver hasn’t visited Victory Lane since last season’s finale in Miami.

He enters Texas with 12 top fives this season, including three runner-up finishes. His five top fives on 1.5-mile tracks trails only Bell (six).

Custer placed fourth at Texas in the spring. He’s finished in the top five in all three of his Texas starts, which is tied with Kyle Busch for the second most starts at Texas before a finish outside the top five.

“(Texas has) been a great track for us in the past and I’m looking forward to it probably more than any track right now,” Custer said in media release. “We definitely have to be on our game and be hunting for a win and stage points as much as possible. It’s doable to make the points up, but we’re going to really have to make some magic happen. We’ll go to Texas with a lot of speed because we always do at mile-and-a-half tracks, so there is no reason we won’t finish well as long as we don’t get involved in a wreck like last weekend.”

Austin Cindric (-43)

The rookie driver has had a harsh campaign with seven DNFs and only four top fives in the first 30 races.

In the playoffs alone, he has one top five and a top 10 in addition to his Kansas DNF and a 13th-place finish at Richmond.

He has the second worst average finish in the playoffs at 15.8.

Cindric finished ninth at Texas in the spring.

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.

Drivers to watch in Clash at the Coliseum

0 Comments

The 2023 NASCAR season will begin with Sunday’s Clash at the Coliseum, the second race on a purpose-built track inside Los Angeles Memorial Coliseum.

Although a non-points race, last year’s Clash generated intense interest as NASCAR moved the event from its long-time home at Daytona International Speedway to Los Angeles. The race was rated a success and opened doors for the possibility of future races in stadium environments.

Year Two will find drivers competing on a familiar landscape but still with a track freshly paved. Last year’s racing surface was removed after the Clash.

Drivers to watch Sunday at Los Angeles:

FRONTRUNNERS

Joey Logano

  • Points position: Finished 2022 as Cup champion
  • Last three races: Won at Phoenix, 6th at Martinsville, 18th at Homestead
  • Past at Clash: Won in 2022

Logano put bookends on 2022 by winning the first Clash at the Coliseum and the season’s final race at Phoenix to win the Cup championship. He’ll be among the favorites Sunday.

Ross Chastain

  • Points position: 2nd in 2022
  • Last three races: 3rd at Phoenix, 4th at Martinsville, 2nd at Homestead
  • Past at Clash: Did not qualify last year

Chastain was the breakout star of 2022, winning a pair of races and generally putting himself front and center across much of the year. Can he start 2023 on a big note? If so, he will have to do so without replicating his Hail Melon move at Martinsville after NASCAR outlawed the move Tuesday.

Kevin Harvick

  • Points position: 15th in 2022
  • Last three races: 5th at Phoenix, 16th at Martinsville, 8th at Homestead
  • Past at Clash: 10th in 2022

Sunday will begin the final roundup for Harvick, who has said this season will be his last as a full-time Cup driver. He is likely to come out of the gate with fire in his eyes.

QUESTIONS TO ANSWER

Kyle Busch

  • Points position: 13th in 2022
  • Last three races: 7th at Phoenix, 29th at Martinsville, 9th at Homestead
  • Past at Clash: 2nd in 2022

Welcome to Kyle Busch’s Brave New World. After 15 seasons at Joe Gibbs Racing, he begins a new segment of his career with Richard Childress Racing. He led 64 laps at last year’s Clash but couldn’t catch Joey Logano at the end.

Tyler Reddick

  • Points position: 14th in 2022
  • Last three races: 23rd at Phoenix, 35th at Martinsville, 35th at Homestead
  • Past at Clash: 21st in 2022

Reddick ran surprisingly strong in last year’s Clash, leading 51 laps before parking with drivetrain issues. He starts the new year with a new ride — at 23XI Racing.

Ty Gibbs

  • Points position: Won Xfinity Series championship in 2022
  • Last three (Cup) races: 19th at Martinsville, 22nd at Homestead, 22nd at Las Vegas
  • Past at Clash: Did not compete in 2022

After a successful — and controversial — Xfinity season, Gibbs moves up to Cup full-time with his grandfather’s team. Will he be the brash young kid of 2022 or a steadier driver in Season One in Cup?
