Callaway Camaro Z/28 SC652

Chevrolet's fanatical pursuit of performance with the Camaro Z/28 is impressive on its own. That said, we can't help but feel that there's a bit more potential to be squeezed from the track-ready muscle car. It seems that the folks at Callaway agree with us, as the aftermarket tuner has released the Camaro SC652.

As you may have guessed, SC652 is an indication of both the new supercharger fitted to the Z/28's 7.0-liter V8 and its increased output, which is up from 505 horsepower to 652 ponies. Torque, meanwhile, has jumped from 481 pound-feet to 620. These new figures allow the Callaway-tuned Z/28 to scamper to 60 in just 3.7 seconds and get through the quarter mile in 11.5 seconds.

The extra oomph was achieved thanks to a number of engine modes, not least of which is the Eaton TVS2300 supercharger. A liquid-to-air intercooler, new fuel injectors, a freer-flowing intake and a better-breathing exhaust also contribute to the Z/28's new sense of speed.

Outside of the engine work, though, Callaway knew what to leave well enough alone - the suspension, Brembo carbon-ceramic brakes and (shockingly) the aerodynamics remain identical to the standard Z/28.

The result is, we suspect, a wildly potent Chevy that we'd happily rocket across both road and track. Take a look up top for a gallery of images from Callaway.
