As you can tell, we're in the middle of big 'ole re-do of the Building Speed site. Bear with us as we switch hosts to one that is hopefully more reliable than the last... If you'd like to see the blogs, there's a mirror at https://medium.com/building-speed/
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 […]
Reverse Engineering NASCAR Stage Lengths
Stage Racing The 2017 NASCAR season brought us stage racing: Segmenting a race into three parts, each of which has a winner (and point reward). If you’re me, the first thing you wondered was not how stage racing would play out. It was “how the heck did they decide on the […]
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 […]
Changing Manufacturers: More than just Decals?
I’d Rather Fight Than Switch If you remember what commercial that was from, then congrats. You are — like me — old. It used to be that an owner was loyal to his manufacturer to the death, but the last few years have seen some big switches in manufacturer affiliations. […]
Safety vs. Speed: 2017 Changes to the Chassis
The Evolution of the Stock Car While many fans decried the look of the Car of Tomorrow, the most significant thing about the COT was a part you couldn’t see: The Chassis. The first time I was around a stock car, I was surprised at how flimsy the sheet metal on it actually […]
Will Tire Limits Improve Racing?
Will 2017 Tire Limit Rules Require Harder Tires? Back in the day, the only thing that limited how many sets of tires you could use in Cup-level racing was your budget. It was different in the lower level series, because Cup teams that also ran XFINITY (for example) had much […]
Will Toyota’s New Nose Change the Cup Series Balance?
The unveiling last Monday of Toyota’s new redesigned race car for 2017 got a little lost between Junior’s wedding and Carl Edwards’ surprise ‘stepping back’ from NASCAR. But every time a manufacturer redesigns and engine or a body, it opens up a giant task for NASCAR. The Level Playing Field A […]
Can NASCAR Stop Secondary Accidents?
January is named after the Roman God Janus, who is the god of beginning, gates, transitions, time, doorways, passages and endings. How’s that for a job description? Janus is usually portrayed as having two faces: one looks forward and one looks backward. So I thought January might be a good […]
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 […]
The Goodyear Blimp… Technically Isn’t
I’ve started work on a new book about how rapidly we’re learning to integrate robotics with human beings. It won’t be too long before we have real-life cyborgs. One of the most surprising things I’ve learned in researching the book is the huge role the military plays in developing advanced prosthetics — which might […]
