NASCAR no longer regulating minimum air pressure requirements

By Dustin LongFeb 13, 2015, 6:09 PM EST

DAYTONA BEACH, Fla. – NASCAR will not regulate minimum air pressure requirements this season, giving crew chiefs more control of how little they put in their tires but also increasing the risk of a blowout.

“How much do you want to risk it to get the biscuit?’’ Joey Logano said. “Except that one hurts a lot more. Believe me.’’

Goodyear will continue to provide teams with a minimum tire pressure recommendation.

Previously, NASCAR mandated the right front tire pressure and, in some cases, left-front tires. Now, it is up to teams to determine how low they inflate their tires.

Robin Pemberton, senior vice president of competition, said NASCAR is allowing teams to police themselves in this area.

“With Goodyear constantly working on their communications with the teams on tire durability, it’s putting it in the team’s hands for different strategies,’’ he told NASCAR Talk Friday at Daytona International Speedway. “How low they think they can go.’’

Greg Stucker, Goodyear’s director of race tires sale, said: “(Teams) have to make those calls. We try to give them as much data as we can for them to make those types of decisions.’’

Pemberton said officials are working on having a tire pressure monitoring system on the dashboard to give drivers a warning when tire pressure is too low. Pemberton said that the system is “a ways away” from happening.

For now, Kasey Kahne said teams will take advantage of lowering the air pressure.

“There are certain tracks where you are at minimum, and if you could go down 2 more pounds, you would definitely definitely do it,’’ he said.

What’s the advantage of lowering air pressure? It provides better grip. That’s pivotal on short tracks and on some bigger tracks with worn and bumpy surfaces. It also is vital on restarts, especially late in a race.

“As a competitor, you have to push limits to make it better, and you get yourself in a box where you’re running on the edge,’’ said Paul Wolfe, crew chief for Brad Keselowski. “If nothing changes at this point, are we going to see a lot of failures? I have a feeling we could potentially.

“I know there’s multiple tracks where we were racing at the Goodyear minimum already and to sit here and say we aren’t going to try to go below it, I’d be lying to you.’’

Low air pressures at Daytona International Speedway are not expected to be an issue because that doesn’t help performance as much. Atlanta, the season’s second race, also might not be a track that sees lower air pressures because of the high speeds and loads. Tracks that could see teams dropping air pressures could be New Hampshire, Martinsville, Kentucky and Auto Club, among others, crew chiefs say.

Last July, Jimmie Johnson suffered two left rear tire failures at New Hampshire. He claimed it wasn’t because of low air pressure but Goodyear said otherwise.

“I think you will more see more variability in whether you want to set up for a short run or a long run when we get to the short tracks and how far you are going to be able to push it,’’ said Cole Pearn, crew chief for Martin Truex Jr. “I really see that is going to be the biggest thing that changes with the air pressure rule.’’

Dr. Diandra: Data points to speed as key to breaking Blaney’s losing streak

By Diandra Leslie-PeleckyMar 30, 2023, 11:00 AM EDT

Richmond Raceway presents a chance for Ryan Blaney to break a losing streak that started after his win at the regular-season-ending Daytona race in 2021. A fast scan of his stats suggests Blaney is off to a good start to do just that in 2023.

Despite a poor showing at COTA, where he failed to run any higher than 16^th all race, Blaney has a season average finishing position of 12.8. He’s tied with Kevin Harvick for fourth-best average finishing position among full-time drivers.

Blaney finished second at Phoenix, where the new short track aeropackage debuted. But he has not won.

Things look good on the surface

Before getting too worried by Blaney’s drought, remember that the season is only six races old. Two of those six races were superspeedway events, and a third was a road course where running through other cars has become the norm.

With 30 more races in the season, it’s far from time to hit the panic button.

Basic statistics suggest that Blaney is matching (and sometimes beating) his teammate, defending champion Joey Logano. I’ve included the statistics for sophomore driver Austin Cindric in the table below, as well.

Logano won Atlanta and has two top-five finishes. No driver has more than three top fives thus far. Despite Logano’s win, Blaney’s average finishing position beats Logano’s.

Cindric has two top-10 finishes and an average finish of 16.5. His best finishes are sixth-place finishes at Las Vegas and last week at COTA.

After the National Motorsports Appeals Panel rescinded the 100-point penalty assessed to each Hendrick Motorsports driver and team, Ryan Blaney occupies eighth place in the season points standings.

Things would appear to look good for breaking Blaney’s losing streak this year.

Digging Deeper

But a different pattern emerges upon diving into the loop data. The next table compares more detailed statistics for all three Penske drivers. I’ve highlighted the lowest-scoring driver’s numbers in red for each metric.

Cindric lags his more experienced teammates in number of laps led, number of fastest laps and number of laps run in the top 15. But in the other stats, Blaney is the third out of three at Penske.

Average running position measures driver performance across all laps of a race, instead of just the last one. Blaney’s best average running position of the season was at Phoenix, with a 7.47. His worst was last week at COTA, where his average running position was 29.28. Apart from Phoenix, Blaney didn’t break the top 10 in average running position at any race this year.

The average speed-on-restarts rank compares a driver’s average speed in the first two laps of each green-flag run to other drivers’ speeds. Blaney ranks 32nd out of 35 full-time drivers in average restart speed rank. That places him behind Logano and Cindric.

Speed early in a run and speed late in a run measure a driver’s speed compared to everyone else on track during the first and last 25% of each green-flag run. In both metrics, Blaney again ranks 32 out of 35.

The fact that top-ranking Penske driver Logano only ranks 12th and 16th in early and late speed respectively suggests that the problem is at least partly company wide.

In overall green-flag speed — the average speed over a full green-flag run — Blaney ranks 29th out of 35. Logano ranks 12th and Cindric 19th.

These numbers identify one challenge that must be overcome to break Blaney’s losing streak.

Year over year

I’ll set aside Cindric’s numbers in this section for the sake of clarity. Blaney’s first six races this year show a large drop-off in most metrics relative to the first six races of 2022. Logano, however, either improved or stayed relatively constant in the same metrics.

In the table below:

Green indicates a 10% or better improvement in 2023.
Red indicates the 2023 value is at least 10% worse.
Black indicates a change (either way) less than 10%.

Blaney has led a little more than 10% of the laps he led in 2022 and has less than half the number of fastest laps. His drop-offs on the speed metrics (the last four rows) are much greater than Logano’s changes.

In 2022, Blaney was beating Logano in all four speed metrics. This year, Logano is ahead.

The Promise of Richmond

The encouraging news to pull from this analysis is that Blaney’s numbers for Phoenix are the best of the 2023 season so far. He ranked seventh in green-flag speed, second in restart rank, eight in early-run speed and fourth in late-run speed. All of that bodes well for a good finish at Richmond.

Blaney won the pole in last spring’s Richmond race and finished seventh. He finished 10^th in the fall race after qualifying 10th.

And Blaney himself is optimistic.

“Richmond will be a good gauge of where you stack up – slow, a bunch of mechanical grip, tire conservation,” Blaney said. “So I’m optimistic for it, for sure. I thought we had good cars there last year in both races from the whole team, and I’m excited to get there.”

But breaking Blaney’s losing streak is only the start to a successful season. He must improve his speed metrics at other tracks if he is to contend for a championship.

NASCAR fines Daniel Suarez $50,000 for pit road incident

By Dustin LongMar 29, 2023, 5:26 PM EDT

NASCAR fined Daniel Suarez $50,000 for running into the cars of Alex Bowman and teammate Ross Chastain on pit road after last weekend’s race at Circuit of the Americas.

Suarez was upset after a potential top-five finish was lost in an incident in overtime.

Suarez restarted fifth in the second overtime restart but left the inside lane open. Alex Bowman, with Ross Chastain and Chase Briscoe aligned behind, charged and got beside Suarez as they approached Turn 1.

As Bowman slowed to make the tight turn, he was hit from behind and that sent him into Suarez, who clipped the left rear of Martin Truex Jr.’s car. Truex spun in front of Suarez and blocked his path, allowing the rest of the field to drive by and costing Suarez a top-five finish. Suarez finished 27th.

Suarez spoke briefly with Bowman before having a discussion with Chastain.

“It’s uncharacteristic of Daniel,” Elton Sawyer, NASCAR senior vice president of competition, said Tuesday on SiriusXM NASCAR Radio. “There’s no excuse for what happened.”

Appeals panel rescinds 100-point penalty to Hendrick drivers

By Dustin LongMar 29, 2023, 4:24 PM EDT

Alex Bowman is back leading the points after the National Motorsports Appeals Panel rescinded the 100-point penalty to each Hendrick Motorsports driver and team Wednesday. The Appeals Panel also rescinded the 10-point playoff to each Hendrick driver and team.

The Appeals Panel found that Hendrick violated the rule by modifying the hood louvers on the cars of Bowman, William Byron, Kyle Larson and Josh Berry at Phoenix. The louvers were taken after practice that weekend.

The Appeals Panel kept the $100,000 fine and four-race suspension to each Hendrick crew chief: Cliff Daniels, Alan Gustafson, Blake Harris and Rudy Fugle. All four sat out the past two races, meaning they’ll miss this weekend’s race at Richmond and next weekend’s race on the dirt at Bristol before returning the following weekend at Martinsville.

The Appeals Panel did not give a reason for its decision.

Bowman had been 16th in the standings with the 100-point penalty. He now has a 15-point lead on Ross Chastain after getting all those points back.

Byron goes from 22nd to third after getting his points back. He’s 29 points behind Bowman, 14 points behind Chastain and five points ahead of Kyle Busch. Byron also gets his 10 playoff points back for his wins at Las Vegas and Phoenix.

Larson goes from 27th to ninth with getting his points back.

“We are grateful to the National Motorsports Appeals Panel for their time and attention,” said Rick Hendrick, owner of Hendrick Motorsports, in a statement. “Today’s outcome reflects the facts, and we’re pleased the panel did the right thing by overturning the points penalty. It validated our concerns regarding unclear communication and other issues we raised. We look forward to focusing on the rest of our season, beginning with this weekend’s race at Richmond (Raceway).”

NASCAR stated its displeasure with part of the penalty being rescinded.

“We are pleased that the National Motorsports Appeals Panel agreed that Hendrick Motorsports violated the rule book. However, we are disappointed that the entirety of the penalty was not upheld. A points penalty is a strong deterrent that is necessary to govern the garage following rule book violations, and we believe that it was an important part of the penalty in this case and moving forward. We will continue to inspect and officiate the NASCAR garage at the highest level of scrutiny to ensure a fair and level playing field for our fans and the entire garage.”

The panelists on the appeal were former driver Bill Lester, Kelly Housby and Dixon Johnston.
