Sciencing Out NASCAR Rules Changes

Rules changes in NASCAR are tricky.  There’s really no way to test them before implementing them. You’re relying on the judgement and experience of the NASCAR team, with input from race teams, drivers, Goodyear and tracks. How to Test Rules Packages? Robert Gauthier (@yetticrg) tweeted a question to me (You…

Pocono Raceway Solar Farm: Sheep Power

People often point to NASCAR as being an environmentally unredeemable sport because it involves cars burning gasoline. For some reason, people looking for an easy answer like to suggest that NASCAR turn to electric cars and that would make everything better. But the cars on track are a very (very) small part…

Infographic: Fuel Mileage Races

Well, it finally happened. They made it so easy to made an infographic, even I can do it. It’s not perfect – the tool I used doesn’t like graphs with fractions, so I couldn’t get it to give me any lines between 0 and 1. But hopefully you can get a relative idea of how much fuel you need to complete a lap at different tracks.

Pocono: The Shifty Triangle

NASCAR engines like to run at about 8000-9500 rpm (revolutions per minute); however, the tires on the car rotate around 2400 rpm at 200 mph. The gearing in the transmission and the rear end gear reduce the rotational engine speed, with different gears providing different reductions. When you talk about the size of a gear, you’re actually talking about the relative sizes of a pair of gears. The gear on the left in the diagram has 20 teeth, while the gear on the right has 10 teeth, so this gear would be a 2:1, meaning that the smaller gear rotates twice every time the larger gear rotates once.
