Worked through a lot of belt gremlins over the weekend with @poweredbyhhp and seemed to have them all figured out. Unfortunately the belt broke in the final of outlaw on the brake. This is in 8.50 just running down the 1/4 for time.

Behind the scenes I've been working with a select few individuals across the world to help them reliably increase the power on their hellcats making them FAST with @drag_ontuning on the keys. Shout to @livinglifefast_llf for trusting the process all the way in the United Kingdom 🇬🇧
