6th Place Street Class
Last year, Alena Oberg, our only female competitor, nearly stole the First Place spot with her supercharged AWD Grand Cherokee SRT8. This year, the SRT8 was in the shop getting even more mods installed, but the Oberg family had another trick up their sleeve. For 2012, Alena's husband, Greg, brought out his '04 Silverado SS AWD equipped with a large displacement LS, a supercharger, and nitrous kit. That trifecta of speed made the other competitors scratch their heads a little as the Chevy was sure to be a serious contender. Other high-dollar items included eight-piston Brembo brakes, Belltech 2/3 lowering kit, and high-performance Nitto tires. The recipe had all of the ingredients, but Greg's SS couldn't finish the first competition. Really getting acclimated to the handling of his truck around the cones, Greg's times started dropping into the competitive range when he heard a loud clunk and then saw coolant spilling onto the track. His 10-rib serpentine tensioner broke, sending the belt and other metal shrapnel flying around inside the engine compartment. His day came to an untimely end, and his murdered-out Silverado was carted away on the back of a flatbed. Don't think for a second this is the last we've heard from the Obergs, as both husband and wife made a commitment to finally settle a Mopar versus Chevy family feud in next year's THROWDOWN.
