Super ‘maro: Callaway Announces 652-hp Supercharged Camaro Z/28

For 25 years, Chevy-tuner Callaway Cars has been making fast cars faster—or wagon-ier, in the case of the Corvette Aerowagon—and it doesn’t look like the company is going to slow down any time soon. Today, Callaway has announced a planned run of 10 Callaway-modified versions of the juicy, track-tuned Camaro Z/28.
Unlike some of Callaway’s more, uh, creative products from the past—the Callaway Camaro Z/28’s modifications are virtually invisible from the outside, and chiefly involve bolting an Eaton TVS2300 supercharger and a liquid-to-air intercooler to the Z/28’s 7.0-liter LS7 engine. Callaway also adds increased flow-rate fuel injectors, carbon injector covers, a high-flow intake system, and a low-restriction exhaust system. Output jumps from 505 horsepower and 481 lb-ft of torque for the stock Z/28—which is naturally aspirated, of course—to 652 horses and 620 lb-ft of torque. Left in place are the Z/28’s lowered suspension, 19-inch wheels and tires, Brembo carbon ceramic brakes, and Tremec six-speed manual transmission. For good measure, Callaway adds its own decorative doorsills, floor mats, commemorative plaques under the hood and on the dash, and an “authenticity documentation package,” in case someone is brave enough to question the authenticity of such a bad-ass sled.
Callaway did not state how much weight its modifications have added to the stripped-down Z/28, which is some 300 pounds lighter than Chevrolet’s own in-house supercharged Camaro, the 4120-pound ZL1, which is quite a beast itself with 580 horsepower and 580 lb-ft of torque.
While we’ve ridden shotgun in a stock Z/28 around the track, we have yet to test one ourselves. But considering that we have recorded a 0–60 time of just 4.1 seconds and run the quarter-mile in 12.3 at 119 mph in the heavier ZL1, the Callaway version ought to be able to hit 60 in the low-to-mid threes and drop the quarter-mile time into the mid-11s. More important to the Z/28’s mission is track supremacy (Chevy says that the Z/28 is three seconds faster around its MRC test track than the ZL1), where an additional 147 horsepower and 139 lb-ft of torque sure won’t hurt, either. No word on how much Callaway plans to charge for its steroidal super-‘maro, but with the stock Z/28 starting at $75,000, it won’t be cheap. But if you’re interested, head over to callawaycars.com.
