The people behind EY3:

Kees Mense – Managing Director

Kees founded EY3 Ltd in 2002, after a 26 year career at Cosworth starting out as a junior engineer and progressing to become a senior manager in charge of engine testing and electronics. Gaining a wealth of experience in manufacturing, design, development and management along the way.

Success was in no short supply, winning countless Formula 1, IndyCar and other Championships around the world. With the legendary DFV engine dominating formula 1 for so many years.

As Managing Director of EY3 Ltd, Kees set up the company, initially concentrating on engine test services such as designing test equipment, engine Dyno control and data logging systems. The fabrication shop quickly followed and the company has evolved and expanded to provide engineering solutions from design through to manufacture. Its loyal customer base appreciate the willingness and ability to problem solve and offer complete solutions.
