🏁 Big shoutout to ISH Racing from all of us at 515 Racing! 🏁

We want to recognize Tyson Enerson and Dave Mart for thinking outside the box and engineering an absolute beast — a compressed air supercharged Pro-55 sled. Huge thanks to Tyson for giving Aaron Casler the chance to pilot this one-of-a-kind machine at GLD!

The two photos of the sled below are from a previous race, but they show off the incredible craftsmanship and innovation behind this sled. 💪 The time slip is from this past weekend at GLD.

This weekend, Aaron laid down an ET of 3.51 at 158.8 mph, officially setting the new Pro-55 class record! 🔥

This is a massive achievement for the sport — something worthy of making a noise about. Be sure to reach out to Tyson and give him a well-deserved congratulations! 👏👏
