11 years later he joined TWR’s sportscar programme which was responsible for designing and building Nissan’s GT1-spec R390. The car scored a podium finish at Le Mans in 1998 before H moved on to help develop Renault’s Clio V6 concept and enjoy a brief spell at Jordan Grand Prix.
In 2000 he moved to America where he has lived ever since. Once there, he joined Dick Barbour Racing’s factory Porsche GT effort that swept all before it in the ALMS. A year later the team ran a pair of Reynard prototypes to the LMP675 class title.
A number of years working for the International Motor Sports Association followed, as well as setting up Krohn-Barbour Racing in 2004, before the chance to help establish Robertson Racing arose in September 2006.
In 2014, H moved into his own dedicated facility, and has been taking on customer projects ever since. If you can dream it, H can build it!
