The New Hampshire Motor Speedway surface will be treated with both PJ1 and the tire dragon
NASCAR track treatment is all the rage these days.
Especially when the national touring series visits tracks that have traditionally been known as one-groove race tracks. Such is the case this weekend at New Hampshire Motor Speedway.
NHMS and NASCAR have announced they will be treating the New Hampshire Motor Speedway surface. An attempt to create more side by side racing.
Two methods will be in place. Both to essentially do the same thing, create options.
This chemical compound will be applied to the middle groove of the speedway.
What: PJ1 is formerly known as VHT. Same stuff, different label. The chemical will be applied to create more grip in the middle lane of the race track.
Where: Middle groove
This method will be applied on top of the PJ1 chemical. However, the tire dragon won’t just be applied to the middle groove. Track officials have also stated that the machine will be used in the upper lane as well.
What: The tire dragon is a machine that drags tires. It lays rubber into the racing surface before a single car touches the track.
Where: Middle and high grooves
Both of these strategies have been used at multiple venues thus far in the 2017 NASCAR Cup Series season.
