The 2015 Corvette Z06 has no shortage of power and performance capability. The new 6.2 liter supercharged LT4 V8 produces a whopping 650 horsepower and 650 ft. lbs. of torque. However, John Hennessey and his crew decided this wasn’t good enough for them. Hennessey Performance Engineering now has ambitions of taking the car to outputs upwards of 1,000 horsepower.
Called the HPE1000, Hennessey Performance Engineering’s improvisation of the 2015 Corvette will come availed in 750 horsepower and 1,000 horsepower variants. According to John Hennessey, the car’s braking system and aerodynamic setup are already at near maximum efficiency and performance. Pursuant to such, most of Hennessey’s upgrades will focus on drive-train components.
Apparently, getting the 2015 Corvette to 750 horsepower, frankly is not that difficult. An upgraded pulley system, new cylinder heads, and upgrades to the camshafts will go a long way towards making the car quicker. For the 750 horsepower variant, the stock supercharger will suffice, but a new intercooler will need to be mounted. These upgrades, some other miscellaneous tuning, and some toying with the ECU will allow the car to make the 100 horsepower jump. Hennessey also chose to retain the GM eight speed automatic transmission over the seven speed manual; the 2015 Corvette comes availed with both options. We know what you’re thinking, but the eight speed in question, equipped with paddle shifters, is one of the most advanced in the world, rivaling the best European dual-clutches in terms of performance.
However, when it comes to the 1,000 horsepower mark, that’s where things get tricky. The internals of the engine will need to be substantially fortified or rebuilt. A new, larger supercharger will need to be mounted, in order to boost the engine sufficiently to yield a four digit number range on the dyno.
With over 1,000 horsepower and a few extra cosmetic perks, the HPE1000 is already sounding like one awesome ride. Pursuant to such, you can bet it’s probably going to come at a cost. With the 2015 Corvette’s sticker at around $78,000, expect it to be well over the $100,000 mark; $150,000 would probably be a very conservative estimate as far as the price is concerned. We also, as of yet, don’t have a definitive release date; though it will obviously probably be within the next year.
