A Band Aid for NASCAR’s Tire Bleeding Problem
There are three things you don’t mess with in NASCAR: engines, fuel and tires.
Tuesday, NASCAR handed down a P5 penalty – the penultimate penalty on the books – to Ryan Newman’s 31 team. Crew Chief Luke Lambert was suspended six races, fined $125,000, and Newman and his owner Richard Childress were each docked 75 points. The tire specialist and team engineer were suspended for six races as well. RCR is appealing the penalty, but I wager they’ve got an uphill battle.
NASCAR’s made its stand loud and clear in the last few weeks. Tire bleeding will not be allowed. If you persist in trying, they’ll come down hard on you.
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.
Where There’s Smoke, There’s Tire
Well, we’re giving the video blog a go. Let’s see if this works… There have been a number of interesting questions recently about tires. Hopefully, the short video below will answer two of them! If you’re interested in more detail, hop over to my companion posting at Cocktail Party Physics, […]
Engine Blowups: A Consequence of the Testing Ban?
The stock car science blog has been a little behind due to a really big project I’ve been working on that has taken up every spare moment of writing time the last few months. The good news is that there (finally) will be an announcement at Texas Motor Speedway the […]
Mailbag: Tire Codes, Bristol Waves and the Science of Cheating
Just when you think things can’t get any busier, they do. It’s the end of the fiscal year at my university, which means getting buried in a mound of paperwork. We’re doing three workshops this fall for teachers on using NASCAR to get kids interested in math and science, plus […]
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 didnt have enough grip to race. That wasn’t the problem today. Lets look at the anatomy of […]
