I can vouche for the runtime of a B5... This weekend was the roughest weekends... For the A-main my engine was nowhere near where it needed to tune wise(due to having tank issues all weekend). And I pitted at 9 minutes on my first round of pit stops and I wasn't on fumes (Shane Racer can tell you that) and Mo can tell you I'm about the hardest guys on fuel milage.
And with all those issues and starting 2 laps back due to a early crash and it cause the engine to quit on the 1st lap and my pit guy had no clue I wasn't racing and was on the end of pit road.I still came back to a 4th in the main.
