About

ACE Racing Engines was founded by Drag Racing enthusiast & Veteran Stefan Rossi in 2010.

After serving in the British Army and returning from a tour of Afghanistan in 2009 Stefan returned to his Volkswagen roots and started Air Cooled Engineering (ACE). Stefan built his first engine age 14 and later went on to win events across Europe with various homebuilt turbo Bugs. By experimenting with his own combinations and modernizing his aircooled builds with newer technologies, such as different ring packs and newer valvetrain components, he quickly grew a reputation for shedding the old-school mythos around aircooled VW engines.

A long running obsession with horsepower and American muscle cars eventually led to building more V8 engines, which motivated Stefan and his partner to chase the American dream by closing their UK operation and relocating to the U.S.A in 2019. Having already gained a large following on social media, they chose to retain the ACE aspect of the business name but rebranded to ACE Racing Engines to reflect the new focus of the business.

Now, with 20+ years of experience and a consistent drive to be ahead of new advances in technology, Stefan has built a solid foundation for successful engine builds, including customers with back-to-back wins, new PB’s, and record breaking times.
