After lightening up the truck a little, Aaron Rudolph clicked off a 9.49-second quarter-mile pass at 147 mph last Friday. The truck picked up 10 mph over its previous best run (which was a 9.75 at 137 mph). Congrats to the Rudy's Diesel crew for constantly pushing the limits of the 6.4L Power Stroke, the 5R110 TorqShift, and diesel performance in general.
