In 2007 he signed with Kenn Hardley Racing to compete in the Indy Pro Series. He struggled with the oval races on the series, but finished well on the road and street courses, recording a season best 3rd-place finish at the Mid-Ohio Sports Car Course and finished 9th in the championship. Kenn Hardley Racing shut down at the end of the season and its assets were sold. He then enjoyed a number of very strong outings for the Creation/AIM LMP1 team in Europe and America before the 2008 recession resulted in the closure of the team and he was again left without a drive.
