How to Make Grippier Racetracks Using Spy Technology
If PJ1 TrackBite isn’t the Solution, What is? Dale Earnhardt, Jr. suggested tracks stop using PJ1 Trackbite because it didn’t work well in Charlotte last weekend. He called for additional research to understand how the substance affects the track before continuing to use it. A couple of drivers expressed similar […]
The Secrets of PJ1 TrackBite
That sounds like the title for a Young Adult book, doesn’t it? What the Heck IS PJ1 TrackBite? NASCAR announced that they are again going to treat the corners of the track at New Hampshire International Speedway with a magic liquid called PJ1 Track Bite. The track enhancer has been […]
Did the All-Star Race Kill the Idea of Two Types of Tires in NASCAR for Good?
Not even the most talented publicity person could convince NASCAR fans that the idea of giving teams a choice of a ‘soft’ tire and a ‘regular’ tire was a good idea based on the sole data point we have: the 2017 All-Star Race. The idea that having one set of […]
Safety vs. Speed: 2017 Changes to the Chassis
The Evolution of the Stock Car ADDITION: If you are more comfortable with Portuguese, check out this translation by Artur Weber and Adelina Domingos – and thanks to them for being interested enough in my work to do the tough job of translation. While many fans decried the look of […]
How is a NASCAR Driver at Bristol like an Astronaut?
The Unique Challenges of Bristol Many drivers will tell you that, despite not having the highest speeds or a unique shape, or a long race time, Bristol is one of the most exhausting stops on the schedule. Laps take about 15 seconds, with about 60% of each lap being turns. […]
How Tracks Take and Lose Rubber
The two words we heard most frequently last week in Pocono (after “still raining”) were “green racetrack”. Rain doesn’t just delay racing. When the race is finally run after a rain delay, it’s run on a different racetrack. To get the details of how a racetrack changes from “rubbered up” […]
Does Grass Pose a Danger to Racecar Drivers?
Now that most tracks have put SAFER barriers on any possible surface, it might seem like racetrack safety is a done deal. That’s not what we’ve heard this week at Daytona, though. Some of the drivers have some strong opinions about grass. “Grass belongs on golf courses. We need asphalt around here […]
Turning at Bristol: A Weighty Matter
A lot of drivers cite Bristol as one of their favorite tracks. It’s a great exhibit for the argument that racing is more than just pure speed. High banks (which we know mean speed!) and a short track, which means tight racing. But a lot of drivers will tell you that Bristol is one of the most exhausting, physically demanding tracks on the circuit. Add to that the inherent stress of short-track racing, where 43 cars are operating in a limited (half-mile) track.
Racing without Friction
Daytona is an enormous, sweeping track. Two-and-a-half miles, 31-degree banking and corner radii of a thousand feet. The infield by itself is 180 acres. If you’ve ever been there (or Talladega), it really does take your breath away when you first enter. Now, bigger tracks (or rather, tracks with bigger turns) automatically […]
Do Tires Affect Gas Mileage?
When winning means a few hundredths of a second, nothing is too small to be ignored. I’ve talked a lot about energy and the importance of using it as efficiently as possible in racing. Gasoline provides a certain amount of stored (a.k.a. potential) energy. Everyone gets the same amount of energy. Winning lies […]
