I put a custom made charging system I designed in a boat owned by a guy who had a handful of rides in the 24 hours of Le Mans, he seems to be in the 24 hrs of Daytona every year. He has to be the most conceited self centered person I ever met. I helped with the install at my customer's automobile electric shop. It was rough holding back not telling the guy off, but since I was in someone else's shop it wasn't my place.
