Drew Donnelli asks: Can you offer any insight into the problems JGR seems to have with fuel supply? Thanks for the question, Drew. As usual, with the help of a couple incredibly patient friends, I […]
A slight errata: This doesn’t change anything about the science surrounding the oil tank box cover and how it could provide an aerodynamic advantage, but it does clarify the situation with how the oil system […]
WeÂ’ve established in Part I and Part II of this series that there are many factors that go into tire performance, some of which Goodyear has control over and others of which they donÂ’t. Goodyear […]
Tires: What Goodyear Can’t Control IÂ’ve reproduced the figure from yesterday to reiterate that there are two factors that determine grip: the interaction between the track and the tire, and the force pushing down on […]
LetÂ’s start by pointing out that tire performance is a really, really complicated issue. There are a lot of variables involved. This post ended up getting way too long, so IÂ’m going to address the […]
Hey y’all from New Orleans. I’m at the American Physical Society meeting, where I gave a talk today to a bunch of physicists about NASCAR. It was part of a great session that included the […]
Roush Fenway Racing came out with a statement about the missing oil tank lid on Wednesday that just begs to be deconstructed scientifically. “The bolt holding the lid in place failed in its purpose as […]
Danny LaDue asks: Can you explain the location of a NASCAR oil tank reservoir and how the lack of one could improve aerodynamics? Thanks for the question, Danny. I can–with a little help from Josh […]
Early in the Las Vegas race, Elliott Sadler, Kurt Busch and Greg Biffle were all caught speeding on Pit Road. NASCAR has a speed limit on pit road for safety reasons. At Las Vegas, it’s […]
