I dunno. Here we go again with NHRA tech. I’m gonna wait and see how this all unfolds. Bead blasting can make a manifold flow better depending on the material used, which wasn’t stated (usually it’s glass, which probably won’t change flow much, if at all), but Tasca says this was done as a cleaning procedure prior to flow bench testing. They also acid dip some of the manifolds. This can also change the flow characteristics and the color, but not the dimensions. Hmmm. I don’t know why they didn’t DQ him from the whole event, and all prior events, since he’s probably running the same manifolds. Based on color alone, that’s not a reason to disqualify somebody.
