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 […]

Running Tracks Backward

The All Star Race, let’s face it, is a series of gimmicks strung together in the cause of entertainment. Not that there’s anything wrong with doing that. It’s what every sport does. People like home runs? […]

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. […]

Transportable SAFER Barriers?

Joel asks:

Can racetracks work together to make interchangeable/transportable SAFER barriers? To clarify – could SMI or ISC tracks (politics, blah) standardize wall heights, angles, etc. so that they could use barriers at Michigan to fill in the critical areas and then move the necessary walls to Darlington or Homestead? Or even simpler – could the existing walls be setup to install barriers that could be moved from track to track? In the long term I know this is probably not the most cost effective solution. But in the short-term if there are supply problems or significant cost barriers, I thought this could help? […]

Does Daytona Qualifying Really Matter?

Okay, it obviously does if you’re one of the cars that fails to make the race. But beyond that- given the huge amount of attention that’s been given to the ’embarrassment’ that was this year’s […]

Skirting the Issue

Flared side skirts became an issue when social media started noticing them somewhere around Kansas. The fact that the most obvious example of this was on the 2 car and Brad Keselowski is rapidly taking over from Kyle Busch as most-love-to-hate driver in NASCAR may have brought the issue to the fore faster.

2015 Rules: Track Records I – The Example of Charlotte

@NASCARRealTime, @TheOrangeCone and @CircleTrackNerd had an interesting dialog when the 2015 rules were announced. They were debating whether the track records that are now standing are going to be essentially locked into history. The debate ended with an appeal to me and Goody’s Headache Powder. […]
