I couldn't care less who believes it, I know from owning one that the Clocked B5 is something special, and until the 'non-believers' own one, or see one run, they're going to keep doubting it ( I would have too )..it's the nature of our hobby. All my mileage claims are in full on race conditions, and I won that race on what would have been a 15 minute tank. Neal does not make things up just to sell an engine, it's just bad-business doing things like that, and Neal knows it.
