John Hennessey and the Hennessey Performance Engineering (HPE) team have been making fast cars go faster since 1991. Over the last 28 years, John and his team have built more than 10,000 vehicles with more than 400 of those in 2017 alone. HPE operates in a soon to be 51,000-square foot workshop and showroom facility situated on 143 acres near Sealy, Texas (about 45 minutes west of Houston).  HPE offers a wide variety of dyno-proven, track tested high-performance engine upgrade packages & parts for a variety of modern performance vehicles. Hennessey Performance is also the only tuner in North America that operates its own test track—the Lonestar Motorsports park 1/4-mile dragstrip facility which is adjacent to the HPE workshop & showroom.
