2006 Hennessey Viper Venom 800R Gallery

Unlike Hennessey’s 1000 bhp Venoms, this one is normally aspirated, but can almost reach the same levels of performance: 0 – 60 mph in 2.9 seconds, top speed over 230 mph and a 1/4 mile time of 10.88 @ 136 mph with Michelin Pilot Sport 2 tires.

These incredible figures are possible due to an extensive engine tuning program that takes Hennessey a little over twelve weeks to perform. From the crankshaft up, every aspect of the motor is reworked, resulting in something almost entirely new. Air enters through a cold air induction system to reported heads, gets compressed by new forged pistons and exits through a big bore custom header and exhaust system. At 5500 rpm, you can bet this swallows about five times the normal amount of fuel.
