Drag strips are sprayed with a special traction compound to help race cars grip the surface effectively.
The Substance: PJ1 TrackBite (Formerly VHT)
The primary substance sprayed on drag strips is a product currently known as PJ1 TrackBite. This product has a notable history and was previously recognized under different names, such as VHT TrackBite or simply VHT.
Based on the provided reference, PJ1 TrackBite is defined as:
- A custom formulated synthetic resin.
- Typically black in color.
- Used in drag racing for specific purposes related to the track surface and tire performance.
Why is it Sprayed?
The application of PJ1 TrackBite serves critical functions on a drag strip:
- Increase Traction: This is the most well-known purpose. The resin creates a sticky surface that allows the high-powered dragster tires to adhere better, significantly improving grip during launch. This enhanced traction is vital for transferring the engine's massive power to forward motion without excessive wheelspin.
- Sealer: PJ1 TrackBite is also used as a sealer for newly ground and/or resurfaced race tracks. Applying it helps condition and protect the track surface, ensuring its longevity and consistent performance.
Benefits of Using Trackbite
Using products like PJ1 TrackBite provides several advantages:
- Maximizes the car's ability to accelerate off the starting line.
- Helps maintain consistency in track conditions across different races.
- Contributes to safer racing by providing predictable grip.
In essence, spraying drag strips with products like PJ1 TrackBite is a standard practice essential for achieving maximum performance and safety in drag racing events.
