For you impatient types, Hennessey Performance Engineering has announced a quartet of performance packs inbound for the 2014 Corvette Stingray. Going with the familiar HPE hierarchy, the upgrades are listed as HPE600, HPE700, HPE800, and the almighty HPE1000 package.
Right off the bat comes forced induction for the 6.2L LT1 Small Block, as the HPE600 employs an Eaton TVS2300 supercharger, an HPE intake, and engine-computer tuning in an effort to attain an estimated 600 horsepower. It will set buyers back $12,495, not including the Corvette it’s going into.
For just another$5955 however comes the HPE700 package, which adds ported cylinder heads and an HPE camshaft to the HPE600′s equipment list for an extra 100 horsepower. The HPE700 is expected to overpower the outgoing Corvette ZR1.
Jumpe to the the HPE800 package, and the supercharger is replaced with a pair of turbochargers. It also comes with new forged aluminum pistons, forged steel rods and crankshaft, along with high-flow cylinder heads, fuel-system upgrades, an air-to-air intercooler, and stainless-steel turbo downpipes and exhaust system. This comes at a fairly steep $54,950.
As for the 1000-hp HPE1000, it adds an electronic boost controller and all the HPE800 upgrades. And for $67,950, high rollers need only apply.
Aside from the (fully warranted—3 years/36,000 miles) performance packages, Hennessey is also offering C7 Corvette owners carbon-fiber body kit pieces and interior trim, monoblock aluminum wheels, a Brembo carbon-ceramic brake upgrade, Penske adjustable dampers, a cold-air intake, and a stainless steel catback exhaust.
