John Hennessey unwinds modified Chevy SS

Tue, 31 Dec 2013 00:00:00 -0800

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.
