John Hennessey unwinds modified Chevy SS

Perhaps it's not as impressive as John Hennessey's recent 200mph blast down Houston's new Grand Parkway in a warmed-up Stingray, but we figured we'd show you his latest run down the same road in a Chevrolet SS equipped with his company's HPE600 Supercharged package. Thanks to GM's engineers, the four-door hits its top speed of 163 in 5th, rather than 6th, but what impressed us the most was watching the numbers climb on the VBOX — the car pulls John-Bonham-hard all the way up to its top speed. Hennessey hasn't released details of the mods performed on the SS yet, but we're anxious to see what this anodyne-looking monster will do on the top end once the gearing nag's sent off to the glue factory.

Ford F-150 SVT Raptor gets turned into 'The Beast'

Looks like we've got ourselves a good ol' fashioned truck horsepower war brewing. Hot on the heels of the debut of the Chevrolet Silverado-based Reaper by Lingelfelter and the Callaway-tuned Chevrolet Silverado, German tuner Geiger has brought out their version of the Ford F-150 SVT Raptor dubbed "The Beast." Apparently, the company felt that the standard Raptor just didn't produce enough power, but their take on the already mental truck is slightly different from Hennessey's approach. Geiger has added a 2.9-liter supercharger to the 6.2-liter V8, bringing the horsepower output up from 411-hp to 572-hp.
