I was at a panel discussion some years ago at a motorsports engineering meeting about materials allowed on the car by different racing series. They had the tech people for IMSA, F1, Indy and NASCAR up […]
@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. […]
In the last blog entry, I explained what brake bias was and how it could be used to improve the car’s handling during green-flag runs. This time, let’s look under the hood (or I guess, more accurately, under the dash) and see how this is accomplished. […]
With all the talk about giving the drivers the ability to change aspects of the setup from within the car, I thought some comments on what types of changes they can make would be appropriate. […]
A persistent motorsports issue (and not only with stock cars) is the aerodynamic passing problem. You can’t pass without grip. Grip is a direct result of downforce. Downforce comes from two places: the weight of the car (mechanical grip) and the billions and billions of air molecules hitting the car (a.k.a aerogrip). […]
Engineering is a constant battle of risk versus reward. How much are you willing to challenge your equipment in order to gain speed? […]
It’s got to be a little frustrating that there are less than 90 days left before the start of the 2014 season and the rules package for the car isn’t set. Teams hope for a […]
There are somewhere in the vicinity of 840 parts in a NASCAR Sprint Cup Engine (at least the Chevy version and yes, I am taking someone’s word for this. I did not have time to […]
Every return to a restrictor plate track brings suggestions about how we might eliminate the restrictor plate. Restrictor plates serve the very necessary function of limiting car speeds at Daytona and Talladega so that the cars stay on the ground. The negative is that they remove throttle response. One suggestion from some readers that I hadn’t heard of before suggested that NASCAR could just change the rear-end gearing parameters to shift the power curve and reduce horsepower that way. Will that work? […]
Four Hendrick Motorsports engines failed at Michigan International Speedway . But Michigan is hard on engines. Let’s see why. […]
