More on the Red Bull Sheet Metal Penalties

After getting in late from Columbus, I made the mistake of listening to the radio as I attempted to sleep. Listening to the comments about the Red Bull Racing penalties got me slightly riled. NASCAR came down hard on Red Bull, including 150 driver/owner points, a $100 kilobuck fine and…

Acid Dipping to Shave Weight

The stock car science blog has been a little quiet lately, mostly because I’ve been working on a really exciting project I hope to be able to tell you all about in the very near future, but also because I’ve been traveling all over the country giving talks and because…

Juan Pablo Montoya’s Shocks

Juan Pablo Montoya’s pole run last Friday at Kansas was disqualified when his shock absorbers failed tech inspection. The shocks and springs are important components of the supension. A car without a suspension would bounce all over the track. When you hit a bump, the springs compress. When you go…

The Scientific Way to Fix the COT

Congrats! If you’re reading this, it means that they turned on the Large Hadron Collider without creating any black holes…yet. If there’s one question I get when I speak it is: “If they were going to design a car from scratch, is the new car really the best they could…

I have never seen Robin Pemberton looking so disgusted as he did during an interview replayed on NASCAR Now Monday evening. (Well, maybe not since Daytona 2007.) NASCAR did a chassis dyno test after the Michigan race on a number of NASCAR Nationwide cars. They found 1/4-inch-thick magnets underneath the…

Goodyear’s Tire Solution

There’s a wonderful gadget called wordle that analyzes text and picks out the words that are used with greatest frequency. So I had it analyze the blog and this is what it came up with. Maybe it’s because they counted tire and tires as two separate words, but I sure…

Treading Lightly: Tires at Indy

Tire problems again, but the issue here was different than the tire problems we saw in Atlanta earlier in the year. At Atlanta, the tire was too hard. The drivers complained that they didn’t have enough grip to race. That wasn’t the problem today. Let’s look at the anatomy of…

Is the Tapered Spacer Rule Fair?

Combustion is the chemical reaction that converts gasoline into motion.  If you remember back to balancing equations in high school chemistry, that often tedious exercise is entirely due to the fact that chemical reactions are just plain picky. The octane molecule – one of the common molecules in gasoline –…
