While NASCAR has made significant advances in protecting drivers from crashes, protecting them from fire is a much different — and much more scientifically challenging — problem. I was reminded of that by how Ryan Blaney’s […]
New for 2018: Data Sharing NASCAR announced (in a somewhat roundabout way) they would share the data collected by each car during races, qualifying and practice with all teams in the 2018 season. This produced a […]
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 This made people like me happy because my friends who denigrated NASCAR as hopelessly outdated and behind the times have one less argument to use against me.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 […]
I get this question a lot: If NASCAR decreases horsepower for everyone, how does that make it easier to pass? You’re basically taking everyone down by the same amount, right? To explain this, we have to […]
Track barriers originally were erected to keep cars separated from spectators. In addition to concrete walls to prevent the cars from driving off track, debris-spewing accidents necessitated fencing to contain airborne objects.
Catchfences should have the same properties as walls, but they can’t block the view. Chain link fence is a good compromise: It’s cheap, plentiful, easy to put up and surprisingly strong given its high visibility.
Chain-link fabric is an elastic metal mesh. It can give in two ways: gentle forces cause the mesh to deform. The diamonds stretch out of shape, but when the force is removed, the fabric springs back to its original shape. The fence can also deform by stretching the wires that make up the mesh. A large-enough force will break the wire entirely. […]
There’s a lot of talk about all the rules changes for 2015. The limiting of the horsepower has been a hot topic of discussion, with people suggesting that NASCAR is basically mandating spec engines. Here’s a […]
I was at a panel discussion some years ago at a motorsports engineering meeting about materials allowed on the car by different racing series. They had the tech people for IMSA, F1, Indy and NASCAR up there […]
