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 […]

Daytona, Catchfences and Flying Cars

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.

Cooling Fuel: Safety or Performance Issue?

Temperatures at the Dover race were unseasonably high. Kurt Busch’s Stewart-Haas 41 team was told by NASCAR officials to remove “heat shields” from their fuel cans. The cans (shown at right) have an 11-gallon capacity. Not shown in the pictures is a tube that connects the nozzle at the top with the […]

How Fast Would NASCAR Cars Go at Daytona without Restrictor Plates?

Doug Yates was guest on Dave Moody’s SiriusXM Speedway last week. He brought up a conversion you hear a lot in the week before Daytona and Talladega. Every 25 horsepower in the engine translates to about a 1 second decrease in lap times. Dave did the math: Removing the plates would increase the engine by 450 horsepower. Four hundred and fifty more horsepower equates to 18 seconds off the lap time, assuming all other things equal. That last part was a very important qualification. It will come back to haunt us in a moment.

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 – […]
