Hennessey SRT700 Upgrade Package For Dodge Challenger
It has been a month since Dodge revealed the Challenger SRT8 and already Hennessey has released a performance package – which has been called the SRT700. In this package Hennessey has added extra cubes to the V8 6.1 liter that has a stroker crankshaft and can pump out 426ci.
For good measure, a 67mm turbocharger system is added as well, complete with an air-to-air intercooler. Forged aluminum pistons, forged steel connecting rods, high-flow cylinder heads, and a 3-inch exhaust system are also added, among other upgrades. The result is a tire-shredding horsepower increase of nearly 75% – 725 bhp at 5200 rpm and 750 lb-ft at 4000 rpm.
Hennessey claims it’s good enough for the Challenger SRT8 to hit 60 mph in 3.5 seconds (with the optional drag radial tire upgrade) and top out at 190 mph. Yep, sounds like pretty typical Hennessey stuff.
