It was only a matter of time before we started seeing tuning propositions for Dodge’s highly anticipated Challenger Coupe. Hennessey Performance, which is widely known for their Dodge Viper conversions, is offering a unique power kit for the Challenger SRT8 that will be available for a mere 25 clients in 2008. The standard 6.1-liter V8 gets a series of upgrades that include: enlarged displacement to 426 c.i. or 7.0-liters; custom 67 mm turbocharger with a front mounted air-to-air intercooler; stainless steel dual 3 in. exhaust system; high flow cylinder heads and an upgraded engine management system.The result is a maximum output of 725 Hp at 5,200 rpm and 1,016Nm (750lb-ft) of torque at 4,000 rpm compared to the standard V8’s 425 HP and 420 lb.-ft. of torque. According to Hennessey, the supped up Challenger SRT700 Turbo can go from zero to 60 mph (96 km/h) in approx 3.5 sec, hit the quarter mile in 11.3 sec at 126 mph or 203 km/h and reach a top speed of 190 mph or 305 km/h.
