A Thousand Horsepower? Hennessey Outlines Several Levels of Pumped-Up C7 Corvette Upgrades

So you think Chevrolet's latest Corvette is pretty grand, but you want more than its stock 455 horsepower? Pity, the C7 ZR1 won't arrive any time soon, and neither will the Z06. Mercifully, Hennessey Performance Engineering's got your back. The tuning outfit has revealed a slew of performance-enhancement packages for Chevrolet's newest Corvette, and the least powerful bundle brings 600 horses to the table. Hennessey's evil plans for the C7 Corvette include four power packs, HPE600, HPE700, HPE800, and HPE1000; and yes, the numbers in those names correlate to the amount of horsepower each one pumps out. The HPE600 deploys an Eaton TVS2300 supercharger, an HPE intake, and engine-computer tuning to reach 600 horsepower. It will set buyers back $12,495 installed. Another $5955 is required to jump into an HPE700, which adds ported cylinder heads and an HPE camshaft to the HPE600′s equipment list for an extra 100 ponies. Hennessey most closely compares the HPE700 Vette to the outgoing ZR1, which Chevy charged a little over $40,000 more for; if the performance is comparable, then it's one heck of a deal.

The HPE800 also employs forged aluminum pistons, forged steel rods and crankshaft, high-flow cylinder heads, fuel-system upgrades, an air-to-air intercooler, and stainless-steel turbo downpipes and exhaust system. The insane 1000-hp HPE1000 also gets an electronic boost controller. All this bonkers output comes at a price: $54,950 for the HPE800 kit and $67,950 for the HPE1000.  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. Our only question is this: Can we mix the HPE1000 gear with Callaway's C7 Shooting Brake conversion kit for the ultimate Stingray wagon? from Car and Driver Blog http://blog.caranddriver.com
