Sprint Cup Changes

On Friday night, teams prepared their cars for the practice sessions that evening, as well as the Budweiser Shootout that was held at Daytona International Speedway on Saturday. NASCAR officials were monitoring the progress and speed of the cars closely. With some cars reaching speeds of over two hundred miles per hour, it was decided to implement a new change to the vehicles, of which the teams have been informed. It is hoped that the changes will benefit the cars, teams and their drivers.

The Sprint Cup Series is a prestigious championship on the NASCAR calendar, with teams preparing and making changes to their cars in anticipation of the start of the new season. Teams will have to begin making the changes to their cars after the Daytona 500, which has been confirmed by Ryan Pemberton, the Vice President of Competition for NASCAR. The changes will involve the cooling systems of the cars, with new front grill specifications being twenty inches in width and two and a half inches in height. Not only will the grills have to be altered, but teams will be expected to lower their water systems to produce thirty-three pounds per square inch, which will be achieved by altering the pressure relief valve that is located on the water system of the car. Some teams will have to adjust their radiators for the pressure relief valve, which will cause the water to flow out if the radiator beings to overheat rather than being contained within the high pressure radiator systems that most cars are fitted with. NASCAR found that the temperatures on most vehicles were running between approximately two hundred and ninety to three hundred degrees, and with the new regulations it is expected to drop to an average of two hundred and fifty.

Pemberton commented on the changes by saying that: “Right now, I think it’s more important to get some things out there. Teams have to go home and prepare (for the cooling system alteration), so it will take several hours for them to get ready for this change. The bulletin was about enabling those guys to spend the time to get prepared and come back on Wednesday.”
