2014 Callaway Corvette
Continued engineering produces significant power

Building upon a history of "Powerfully engineered automobiles", Callaway has continued to press forward in search of better performance.
The LT1 used in the Corvette features many new technologies to bring the lowly pushrod-riddled engine into better efficiency, power and driveability. In keeping with those advancements, Callaway has gone back to the drawing board to bring their power-enhancing packages on par with the best that Chevrolet has to offer.
Callaway's third generation Corvette supercharger system is a completely new design. Callaway engineers developed a new supercharger housing and associated 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.
In dynamometer testing, inlet air temperature increased by less than 10ºF during individual 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.
Durability testing and validation, performance and drivability testing, and emissions compliance testing to establish final powertrain management calibration are scheduled to conclude in May. Then, Callaway Corvette advertised horsepower and torque rating can be released. During development testing, the Callaway supercharged LT1 has produced at least 620 horsepower and at least 600 lb-ft of torque.
