Joseph Potak, also known as High Performance Cult, is a performance consultant, ASE Certified Master Technician, and automotive writer and enthusiast. He has been elbow deep with the LS-Series of engines for the better part of the past two decades, building performance-enhanced vehicles, testing engines on dynamometers, and constantly looking to push the performance envelope further every day via R & D projects. While well known for his long tenure at Texas Speed and Performance and as a veteran moderator on LS1tech.com forums, Joseph’s automotive career has taken him to several countries abroad. Formerly, he enjoyed changing things up and building turbocharged Mustangs for fun (as a fun contradiction to his LS-themed daytime career). He currently stays busy providing third-party consultant services for the performance industry. His personal vehicle collection is mostly LS-powered.
