Are Posted Lap Speeds Really Accurate?
After every practice and qualifying session, NASCAR puts out one or more sheets of paper that look like this: This tells you who went how fast qualifying at Atlanta a couple weeks ago. I only included the first 12 lines because I think you get the idea from here. You can look […]
The Proposal to Muffle NASCAR Race Cars
Last week, Adam Stern broke a story that NASCAR is considering 15 to 20 potential changes that would help increase the fan base. They’ve already implemented race segments and we’ve heard talk about shortening race weekends from three to two days. Stern’s article says that one of the ideas on […]
Did EFI Make NASCAR Engines More Reliable?
In 2012, NASCAR moved from carburetors to Electronic Fuel Injection (EFI). This made people like me happy because my friends who denigrated NASCAR as hopelessly outdated and behind the times have one less argument to use against me. There were many purposes for the switch to EFI: one was precisely as I note above: to be […]
NASCAR’s Laser Inspection Process: Confidence and Accuracy
There Will Be Rules… The last time I was at the R&D Center, I was given a copy of the official NASCAR rule book for 1948. It was about a quarter of a page. Now there’s a thick booklet filled with detailed specifications, part numbers, measurements, tolerances and AutoCad drawings. Weekly […]
Did Jeff Gordon Really Start NASCAR’s “Youth Movement”?
Admit it. You (like me) have sat in front of the television watching pre-race interviews for a Camping World Truck Series race and asked yourself “Is that kid even old enough to drive?” I thought maybe it was just me getting old, but the numbers bear me out. NASCAR drivers […]
Analyzing Chase Tracks
Every year about this time, someone grumbles that The Chase needs a road course. The frequently-cited rationale is that the regular NASCAR season has two, so a champion should prove he or she can perform on the same racetracks that make up the regular season. This seemed like one of […]
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 […]
Cooling Fuel: Safety or Performance Issue?
Temperatures at the Dover race were unseasonably high. Kurt Busch’s Stewart-Haas 41 team was told by NASCAR officials to remove “heat shields” from their fuel cans. The cans (shown at right) have an 11-gallon capacity. Not shown in the pictures is a tube that connects the nozzle at the top with the […]
Age and the NASCAR Driver: Can They Still Compete?
Jeff Gordon’s decision to step away from full-time NASCAR Sprint Cup racing has resulted in a lot of discussion about aging drivers. We’re on the verge of a turnover as a number of drivers (Johnson, Stewart, Junior, Harvick among others) reach their forties. And what an appropriate topic for this week […]
A Numbers Geek Looks at Las Vegas
A couple observations about history at Las Vegas…
