What drivers said after Charlotte

2 Comments

Here is what driver’s had to say after the 57th annual Bank of America 500 at Charlotte Motor Speedway.

Jimmie Johnson – Winner: “No, I didn’t wonder, I just knew it was taking way too long. When you drive for Rick Hendrick and have all the great people at Hendrick Motorsports working for you, the great support from Lowe’s and everyone in their stores and Chevrolet. There are just so many great people behind us and that support us to make this happen. We knew we would get back. Yes, it was slower than we wanted it to be but to be here today and have this victory is great. Thank you to Sprint, to the fans, to Gatorade, and to Valvoline. This is something very special to our team.”

Matt Kenseth – finished second: “They did a great job. Honestly, last two years in a row pretty much Charlotte has kind of taken us out of the Chase – mostly my doing, different things happening the last couple years here – so had a lot of problems last year, this year we had a lot of problems again, but we were able to kind of rebound from them and just kind of take our time. We knew it was a long day and they had good pit stops, good strategy and got us back where we needed to be there at the end.”

Kasey Kahne – finished third: “It was quite the battle to get there. We had our work cut out for us. We got to where we were a lot better the first 30 laps of a run the last three runs there.  That helped us get some track position and avoid a couple of those wrecks. That was tough on a couple of those teams. I know Chase (Elliott) was part of one. I didn’t see what happened, but that is tough for those guys that are battling for this championship. Congrats to Jimmie (Johnson) and the Hendrick Engines, No. 48 team, those guys did awesome. Our Great Clips Chevrolet was strong the first 30 laps and then it would fall off a little bit. It was still a strong day. We did pretty good. We fought hard; the team had great pit stops all day also.”

Ryan Newman – finished fourth: “We had a good race car no doubt. The Caterpillar Chevrolet was strong, especially at the end of the run on top all day long. Just came up a little bit short there. I know some other guys had some problems, but I want to thank the fans that came back today and hopefully enjoyed a great race. We will keep digging. This is building for us for the rest of the year and starting next year.”

Kyle Larson – finished fifth: “It was a good finish for our Target Chevy team. We had a right-front tire come a part there early in the race and was stuck a lap down for a long time, but we were able to get our lap back and finish fifth. I thought I was a little bit better than fifth out of the good guys that wrecked and cars that were left. I will take a fifth today it was a hard-fought fifth.”

Kyle Busch – finished sixth: “There early on we had a tire come apart and that just kind of ruined our day. Right from there, it just seemed like we were playing catch up and thought we were going to have a good opportunity to have a good finish and then we had the 3 (Austin Dillon) spin his tires and clog up the inside lane and just chaos started and I did the best I could to try to avoid it and I didn’t want to check up too bad and slow down too much and get run over, but I ran over the guy in front of me, so I hate it that we ruined Chase’s (Elliott) day like that, but, man, things happen quick like that on restarts too, so I wish it – we had a little bit better breaks, but we certainly didn’t have a whole lot go wrong like some of them other guys.”

Brad Keselowski – finished seventh: “It’s a solid day. To run seventh is OK. We just weren’t quite anywhere near as fast as the 48 (Jimmie Johnson) and the 24 (Chase Elliot), and we were behind a bunch of the others, so we just need to find a little bit of speed, but the execution was great. On the last pit stop my guys got the Wurth Ford out with the leaders, which was really good. We’re executing well. We just need to find a little bit more speed to be able to make that execution and speed and win races.”

Kurt Busch – finished eighth: “We went through a lot today. The restart, I guess we survived it better than most when everybody had that trouble. We just missed on the setup on the first five laps and then after 30 laps, man, she would just go away. We got what we could out of it and all-in-all an eighth-place finish, guys had trouble, it is one of those days where you just go ‘alright’ we will take it. It’s not the best, but with Haas Automation, Monster Energy, that is the finish we need to advance through this Chase.”

Tony Stewart – finished ninth: “Real proud of my guys today. We battled hard. The pit stops were great. I didn’t think I’d have a top-10 at the end of the day.”

Jamie McMurray – finished 10th: “I got lucky to get through the wreck. I thought we were torn up a little more than what it shows there. I don’t know we were really good the first 200 laps and then for some reason the last 100 we just couldn’t go on restarts, didn’t hang on very well.  We just didn’t have the speed we did earlier in the day, but still pretty solid day for both (Chip Ganassi Racing) cars.”

Danica Patrick – finished 11th: “The No. 10 Aspen Dental Chevrolet was loose for most of the race. Billy (Scott, crew chief) and the guys did a great job on adjustments to get us in solid position for the second half. We had a mistake on pit road late in the race and lost some ground when I overshot the pit stall, but the guys quickly recovered and we ended up only losing a couple of spots. The car got a little tight, but they took some wedge back out, and it was pretty good there at the end. I was really hoping we’d end up getting a top 10, but (Jamie) McMurray got us on the last lap, so we ended up 11th. Still, I think that’s our best run so far this year, so we’ll take it and try to keep building over the last few races to put ourselves in a better position for next season.”

Carl Edwards – finished 12th: “We had all sorts of trouble today. We had something wrong with the exhaust and then thought we had a tire coming apart and an engine coming apart – it ran for about 400 miles I guess so hat’s off to TRD, they did a good job keeping that together. I all but wrecked and somehow came out of that and then we had a lug nut hang up in the gun so we had all sorts of adversity to come out of here with a cushion on ninth so this is good.”

Martin Truex Jr. – finished 13th: “The clutch went out. I had the clutch on the floor sitting there in first gear when they dropped the right side and the clutch just pumped up and pushed my foot all the way up so the clutch just went completely out and I had no clutch at the end. I had to start it in gear and luckily we were able to get it started. Not sure what happened, just one of those freak deals. Just happened at the wrong time.”

Chris Buescher – finished 16th: “Overall, it was a tough day to move forward. There were a lot of wrecked race cars, which I was kind of surprised about. The track still had decent grip. It was nice and cool out, but it just led to a wild race. I guess everybody was figuring they’ve got a little cushion. They’ve got two more races before they really have to worry about the cutoff, so this was one of those days that we kind of expected three weeks ago.”

Landon Cassill – finished 19th: “We had a pretty good car up until we got some damage on that big wreck and that kind of killed my speed. We were fortunate we could at least maintain position on fuel mileage. It all worked out. The fuel-saving got us back to where we were running before the damage on that restart. These races at Charlotte seem to be pretty unpredictable, which is why they’re so much fun.”

Ricky Stenhouse Jr. – finished 20th: “We struggled with the handling. Under the right circumstances we could have probably finished on the lead lap but I got a speeding penalty on pit road under the green flag pit cycle. It was a crazy race. It was good points day for us though. We’ve got six more races to learn from and carry that momentum into the off-season.”

Denny Hamlin – finished 30th: “Just an engine failure there. We hadn’t had one in a long time with TRD (Toyota Racing Development) and Toyota. It’s just my time and it’s usually Chase time when I have these things happen. Tough break obviously. Had a good car and we’ll have to go to Kansas and get a good run there and do everything we can to advance.”

Austin Dillon – finished 32nd: “I am fine, it just sucks. We will have to work hard the next two weeks to get the points back.  I felt like I got to third gear pretty clean and then the next thing – I feel contact and I am spinning through the grass. It’s part of it and we took two tires there and you know the risk when you get into it. You just hope that doesn’t happen obviously. I got to third without spinning the tires, and I felt like we got contacted. We will just go on to next week.”

Chase Elliott – finished 33rd: “I think the No. 3 (Dillon) they stayed out on tires and tried to get some track position. The No. 78 (Truex) ended up getting him out of shape and then after that I tried to check up. I don’t think the No. 18 (Kyle Busch) saw it, got into us and got us turned the wrong way. It happens we just got to go and try to have more runs like that next week.”

Paul Menard – finished 34th: “I have no idea. We got behind early and just got back on the lead lap, making some gains with the No. 27 Valvoline/Menards Chevy. Excited to be back on the lead lap and then that next restart everybody just kind of checked up and I got pushed out to the outside wall and couldn’t see anything, I just ran into Chase (Elliott). I’m not sure what started it all. I guess some guys took two tires, probably spinning tires and bumping and shoving each other.”

Greg Biffle – finished 35th: “Everybody got checked up there and sideways. My spotter did a great job and kept me out of it. I kind of thought everything was clear and I let off the brake and the 27 was spinning when all of a sudden somebody bounced off the wall right out in front of me. I didn’t see where they came from or what they did. We weren’t going very fast, but just enough to do a bunch of cosmetic damage and knock the oil cooler and radiator out. I don’t think we’re going to get that fixed and get the duct work back in it. The nose separated from the splitter, so it’s unfeasible to fix it in that amount of time.”

Joey Logano – finished 36th: “We’re not out by any means. We had a very fast car. I’m super-proud of the car we brought here. It was capable of winning, for sure. We ran up from 10th to third and was still running down the leaders early in the race, so I felt really good about the Pennzoil Ford we had. Things happen. It’s part of racing, but we’re not out. We’re not gonna die. This team is resilient. We’ve proved it before and we’ll just have to go out and prove it again. We just have to have two flawless races. It’s something we can make up.”

AJ Allmendinger – finished 37th: “I’m alright that was definitely a hard hit when you start from the bottom and get to the top not the way you ever want to hit. I’m not sure what happened. First off I can’t thank all my guys enough. Harris Teeter on the race car, Stouffer’s, everybody that is a part of this, built a brand-new race car it’s our first one since really the beginning of the year. It had a lot of speed in it. There is something weird that started to happen kind of I would say the first third of the race to where I didn’t like what was happening with the front end of the car. I couldn’t tell if it was just rubber build up or anything like that, but we kept having tire problems with 15 laps to go in the run. Had one start to delaminate and the same thing right there, I started feeling something go again and I don’t know if the tire went or something broke, but something was definitely starting to get messed up in front of cars when was costing us speed. We had a lot of speed early in the race, probably the most speed we have had all year at a 1.5-mile early in the race. There is something to be positive about just not the way we want to end it.”

Kevin Harvick – finished 38th: “No, it just suddenly shut off and the things that it points to are no oil pressure. It’s definitely not a power issue with the battery or anything like that. They are trying to diagnosis it. I hate it for everybody on our Busch team they made some great adjustments today and got our car back where we needed to be to run up front and everything was going fine. Lots of things can go wrong and today they did.”

Alex Bowman – finished 39th: “Blew a tire I guess. It’s really unfortunate. I hate it for these Axalta guys. Everybody at Hendrick Motorsports worked so hard. They brought a great race car here, brand new and destroyed it. Really unfortunate, but it’s not anybody’s fault. We didn’t hit anything we just must have run over something.”

Casey Mears – finished 40th: “I don’t know. I just was going into the corner and I saw him come up all of a sudden. I don’t know. It’s too bad he didn’t put us out of our misery there. We were having a rough start of it. We were just kind of hanging on and actually those guys were going by us. They either blew a right-front (tire) or had something come loose or something and came up into us.”

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.
