Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.
Aesthetically, the Callaway Corvette borrowed a styling cue from the C6 Corvette ZR1, with its engine protruding through the hood. It's a rather clean look, and Callaway claims it further improves heat transfer.
The total cost for the 2014 Callaway Corvette is $22,995, in addition to the cost of a donor Corvette. Take a look below for a brief press release from Callaway.
A production prototype 2014 Callaway Corvette was displayed at the NCM Bash, National Corvette Museum in Bowling Green, Kentucky, on April 24th through 26th. Callaway staff was on hand during the weekend to answer questions about the new car and conducted an in-depth "walk-around" on April 25, presenting the new Callaway Corvette's features. That presentation can be seen on corvetteblogger.com soon.
During development testing, the Callaway supercharged LT1 has produced at least 620 horsepower and at least 600 lb-ft of torque. Callaway's advertised SAE-corrected horsepower and torque rating will be released following final powertrain management calibration, scheduled to conclude in late May. Durability testing and validation, performance and drivability testing, and emissions compliance testing must be completed first. Then, Callaway Corvette production can commence.
Callaway's third generation Corvette supercharger system is a completely new design. Callaway engineers developed a new supercharger housing and integrated intake manifold for improved airflow and increased charge air cooling capability. Intake manifold runner cross-section and length were tuned for a broad torque band while maintaining excellent peak horsepower. Eaton's 2300cc TVS rotor pack was selected for its high thermal efficiency, OEM-certified quality, and service-proven reliability. A new triple-element intercooler configuration provides significantly lower inlet charge air temperatures than possible with single and dual element designs. Because of the added volume of the new internals, the supercharger housing itself extends through the hood. Consequently, both conductive and convective heat transfer mechanisms are utilized to remove power-robbing heat from the inlet charge.
To illustrate the increased efficiency of the Callaway intercooling, inlet air temperature increased by less than 10oF during repeated dynamometer runs, compared to increases of at least 35oF with other intercooler designs. That means more consistent performance at the track and dragstrip, as well as increased power on the street during summer months. To prevent drive belt slippage, a new 10-rib pulley system has been incorporated. In fact, certain new technical features are significant enough that utility and design aspects of this system are patent pending with the US Patent and Trademark Office.
A new Callaway Corvette exhaust system utilizes a single acoustic chamber (muffler) to attenuate harsh frequencies and accentuate low frequency tones, while allowing spent gases to exit the exhaust system with minimized restriction. Callaway's signature Double-D exhaust tips are significantly larger than previous Double-D tips to complement the new Corvette's center exhaust bezel.
New composite manifold base covers, exterior emblems and interior badging further distinguish the 2014 Callaway Corvette. Package MSRP is $22,995.
