That Time Hennessey Attempted 230 mph in a Viper – Part 1
Hennessey Performance recently grabbed a lot of headlines for hitting 270.49 miles per hour with its 1,244-bhp Venom GT.
But reaching such insane speeds hasn’t always been so easy for the Sealy, TX tuner. Back in 2008, it juiced up a Dodge Viper Competition Coupe with twin turbos and a slew of other hi-po goodies in an attempt to go 230 mph over the course of the Maxton Mile. Thanks to those snails, a big intercooler, revised plumbing, a new camshaft and a tweaked engine computer, the snake strikes with the force of 1,450 horses, a 350-hp bump over HP’s previous entry that did 225. And that’s with less boost than the old car. Getting up to 230 should be a cake walk.
Not so fast. (No pun intended. OK…maybe it is.)
The Hennessey creation is so damn powerful that when driver John Kiewicz shifts into fifth gear, a turbo energy grenade explodes, turning it into shrapnel. Luckily, the crew has another $3,000 transmission in reserve. Thirty minutes later, it’s in the road rocket.
Then the computer acts up. In fifth gear. A certain show must not be very popular at Hennessey HQ.
Will the Viper hit the magic number? Stay tuned for Part 2.
