Callaway C7 Corvette Z06 revealed at Museum bash

Tuning

Revealed today at the National Corvette Museum C7 Bash in Bowling Green, the new Callaway C7 Z06 features the famed tuners new GenThree supercharger system with 32% more displacement than the stock Z06 supercharger, improved manifold design, and unique triple-element intercooling system.

According to the press release, Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature, and by exposing the superchargers large plenum area to outside ambient airflow, the design takes advantage of the significant charge air temperature reduction provided by convective cooling.

The completely redesigned intercooling system also helps maintain nearly ambient charge air temperature with exceptionally low air restriction. Plus, the supercharger housing geometry was configured to allow further optimization of the charge air path – all leading to increased power and torque without the compromises faced with underhood solutions.

Horsepower and torque numbers are still pending final validation. The package is priced at $16,995.

Update July 28, 2015:

757 bhp / 777 lb-ft Z06-based Corvette upgrade boasts 32% larger supercharger, triple intercoolers, and consistent power – lap after lap

The Numbers – Callaway Cars today announced power numbers and performance for the flagship model in their performance car lineup. Equipped with Callaway’s GenThree Supercharger, the Corvette Z06 now produces 757 bhp @ 6,200 rpm and 777 lb-ft @ 4,500 rpm (SAE). A launch to 60 mph is now achieved in 2.8 seconds, and a quarter-mile in 10.5 seconds at 131 mph.

Why Go Big, When You Can Go Bigger? – Size Matters. To reach that power (which is up from 650 bhp / 650 lb-ft) the supercharger itself needed to be bigger since the output of a positive displacement supercharger is proportionate to its size. The Callaway GenThree supercharger is 32% larger in displacement (2300cc vs 1740cc).

Cooling – Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature associated with forced induction. Callaway’s unique triple-element intercooler configuration provides significantly lower and well-managed inlet charge air temperatures than single or smaller dual-element designs. The supercharger housing extends through the hood, thereby exposing it to outside ambient airflow and adding an element of convective cooling. The supercharger is visible without opening the hood, and heat is inherently extracted from the engine compartment.

Bold Packaging – The supercharger assembly is no longer cramped below the hood line. The completely redesigned manifold helps maintain consistent charge air temperatures with exceptionally low restriction and even airflow distribution to all cylinders, which results in a broad torque band producing over 500 lb-ft from 2,000 to 6,400 rpm. This translates to more consistent power delivery in severe-duty driving environments, a compromise typically observed with “underhood” approaches. A 10-rib drive pulley system was also integrated to prevent belt-slippage.

Patents – The technical features of the Callaway GenThree supercharger are significant enough that utility and design aspects of the system have been awarded patent pending status through the US Patent and Trademark Office.

Competence – 35 years of experience, compliance and warranty. All Callaway cars are assembled to precise engineering specifications by expert technicians at Callaway facilities, exclusively. Callaway provides the most comprehensive standard warranty among all specialty manufacturers. All Callaway cars are also fully emission-compliant. Additionally, there is an optional 5 year/60,000 mile Extended Powertrain Service Contract on all 2016 models.
