Recently the folks over at Motorweek received an early gift from Santa this year, with the big guy leaving the popular television show not one, but two Callaway customized Chevrolet Performance cars for them to review for a recent episode. When the dust settled and the tire smoke was cleared off, it was obvious that Callaway has not lost the charm and engineering know how that has helped make their cars a favorite among GM enthusiasts.
The first model featured was the 2015 Callaway Corvette SC627 and this beast certainly lived up to its high performance credentials while also serving as a potent visual reminder of the early turbocharged Corvettes that helped jump start Callaway’s rise to success. While we agree with the Motorweek team in regards to our dislike of the cheap looking powder-coated supercharger cover, there is only high praise for the 627 horsepower that charges its way to the rear wheels thanks to the help of the fore-mentioned supercharger which features three intercoolers for improved cooling. The engine modifications also help the Callaway blitz its way to a 3.4 0 to 60 time, though we are curious to see how Callaway will respond when its potent beast is out-muscled by the 2015 Corvette Z06 and its 650 horsepower V8.
On the other end of the performance spectrum is the 2015 Callaway Camaro Z/28 SC652 which is Callaway’s unique approach to the already potent and track-ready Z/28 Camaro. In this application, the familiar Eaton TVS 2300 grade supercharger is bolted onto the 7.0 liter LS7 V8 and that allows horsepower to climb from 505 horsepower to a stable busting 652 horses with the equally stout 620 lb-ft of torque serving as the proverbial icing on the cake. While these figures are still not quite enough to beat the insane 707 horsepower wielded by the Dodge Challenger SRT Hellcat and its 6.2 liter supercharged V8, it is still capable of allowing the SC652 to thunder its way to a 3.7 second 0 to 60 time as well as achieve an 11.5 second quarter mile pass at 124 mph.
Unless you want to sit through a BMW X4 review, and other segments, the Callaway supercars can be seen in their raw glory in the video below at around the 19:15 mark.
