As I remember, the 14-71 was put on because Dave had it. Yeah, it looked awesome, but it was so big that Tonya was concerned about driving the car. If she drove the #1 course -- where turn out to the right is okay (left is "I need help") -- she wouldn't be able to see where she was going 'cvause the blower was in the way.
Also the combination made too damn much horsepower -- the car wouldn't hook up. That's why K & D and crew removed the blower and installed the bottle. I don't remember if the Camaro set a record with the blower, though, but might have.
They were pitted about two cars from us -- and spent most of SpeedWeek wrenching. Where's the fun in that? I mean, SpeedWeek is for visiting with other racers, right?
