Mountune Racing Engines Are Built to Win

Known for our reliability and professionalism mountune USA has been the choice by championship winning teams to develop and assemble their racing engines. Mountune built engines helped Ford Zetec and Duratec engines dominate World Rallycross (WRC) and Global Rallycross (GRC) in the 90's and early 2000's. In 2019, Honda Performance Development (HPD) selected Mountune USA as the official engine services provider for their FIA Formula 4 & FR Americas racecars for our extensive experience in the development, build, and operation of high performance racing engines.

Most recently, grassroots racing team TSC Motorsports won their second King of the Mountain title in their 2021 race at the 99th Running of the Broadmoor Pike's Peak International Hill Climb in with a mountune USA built racing engine. TSC Motorsport driver, Robin Shute, set records in his 2019 King of the Mountain win at Pike's Peak driving a mountune USA built engine in the unlimited class.
