Project Tweety Bird is coming along but now it needs a new name… 🤣 Any ideas?

Pretty neat collaboration with this particular truck/ project.

Can’t wait to share more!

Something I’ve dreamed about for a long time was taking what we’ve built here in the U.S. diesel drag racing scene and sharing it with another country.

This past weekend, we made that dream a reality in Montemorelos, Mexico, at autodromogf_montemorelos during the El Desgajadero event.

We entered our truck in the 4x4 class, and from the very first test pass, we knew we had something special. We reset the hometown track record twice during testing with a 4.85 and then a 4.83. When race day came, the truck performed flawlessly, and we were able to dominate the competition and bring home the win in our class 🏆

As incredible as the victory was, the trophy wasn’t the biggest accomplishment of the weekend.

My goal was to leave the U.S. and show diesel enthusiasts in another country what we’re capable of. The response we received was overwhelming. We had people constantly stopping by the truck, asking questions, wanting to learn, and genuinely amazed by what a diesel truck could do. Being able to share knowledge, take pictures with kids, sign autographs, shake hands, and build friendships across borders meant more than any win ever could.

None of this would have been possible without the incredible team behind us the builders, manufacturers, sponsors, supporters, friends, and family who continue to believe in what we’re doing. Thank you for making opportunities like this possible.

To everyone at El Desgajadero, Autódromo GF, and the people of Montemorelos thank you for the hospitality and for showing us an unforgettable time. We were honored to represent the U.S. diesel racing community, and we can’t wait to come back.

Until next time, México… 🇲🇽
