Back to Thunderhill West for my first time there with my Street Class build and managed to take my first P1! Still using the Verus V2 pan but will have news on the oil pressure series soon. 

In addition to the PB lap, I included a look at what it takes to set of a hot lap—lots of attempts and perseverance. 

Thanks to @RaceTreads and GT Radial for sponsoring 86 Challenge. 

Musical interlude by my brother @jason.scissorfeet.
