cars news 10: ZL1-Based 740-HP 2017 Callaway Camaro SC740 Revealed

Although the 2017 Chevrolet Camaro ZL1 shown this week won’t go on sale until fall, the aftermarket already has plans to boost the muscle car’s power by a noticeable amount. The 2017 Callaway Camaro SC740 adds an additional 100 hp to the new Camaro ZL1, bringing total output to an estimated 740 hp.

Callaway starts by replacing the 6.2-liter LT4 V-8 engine’s stock 1740cc roots supercharger rotor pack with the company’s larger GenThree TVS2300 Supercharger System. The supercharger housing and integrated intake manifold are said to reduce charge air temperature and increase airflow quality resulting in denser air and more power. The Callaway TripleCooled intercooler system with three low-restriction intercooler elements further reduces intake air temperatures, which provides more consistent performance at the track or drag strip, according to Callaway.

Thanks to the 32-percent larger supercharger rotor pack displacement and electronic management programming, the 2017 Callaway Camaro SC740 bumps the Camaro ZL1’s power from 640 hp to an estimated 740 hp. A new hood allows the larger supercharger housing and intercooler system to peek through the muscle car’s engine bay. The Callaway Camaro SC740 is available with the six-speed manual or the ZL1’s new 10-speed automatic transmission.

Callaway says the new Camaro SC740 makes more power than any other domestic sports coupe including the stock 640-hp 2017 Chevrolet Camaro ZL1, 670-hp Ford Mustang Roush Stage 3, and 707-hp Dodge Challenger SRT Hellcat.

Where the 2017 Callaway Camaro SC740 is only available in coupe form, the Camaro SS-based Callaway Camaro SC610 is available with coupe or convertible bodystyles. The Callaway Camaro SC610 features the same GenThree TVS2300 Supercharger as the new SC740.
