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.

      Ruins the car. This thing is supposed to be an all-natural track killer. Save the boost for the ZL1. The LS7 has thin cylinder walls, anyway. That's why GM uses a 6.2 in their FI applications.

        This seems to be a fairly low boost application though. The horsepower is only increased by 30%. I am guessing it's only about 5-6psi boost.

      If you want a Supercharged Camaro buy a ZL1.

      Soooo... basically, they're gonna charge $20k for a $6k supercharger.

      Dumb. An LS7 responds so well to some headwork, cam and some tuning, then some longtubes and a 3" exhaust ( stock is 2.75) that would further reduce weight. Why would you screw the vibe of this car up with a blower.

        Agreed 100%. Basically they just added the weight Chevy removed off the SS back onto the car, know you will likely run into heat soak issues on a road course, and lets be honest the LS7 will make great power when boosted it's not know to be the best application for adding boost to. The LS7 shines at being a bad ass N/A motor IMO.

      There's a reason the GM didn't supercharge the Z28. It has to live on the racecourse…the Callaway is just a street car.

      But Chevy skipped using a blower to save weight, so Callaway has ruined it. They didn't use the LS7 just because they had a few left over from the C6 Z06.

      7.0L naturally aspirated engine only producing 505hp, what are you americans doing !!

      7.0L naturally aspirated engine only producing 505hp, what are you americans doing !! we'd get way more out of that in europe and use less fuel

        It's not about peak power, it's all about the power delivery. And nothing naturally asperated on your side of the pond has the power curves that an LS engine does. Nor will they go 150K+ miles without major maintenance, like an LS engine will. Nor are they as easy to tune, modify, or maintain. Stop thinking of peak power as the end all be all; trying considering the whole engine for once, and realize this *7.0 Liter V8* is physically smaller than most V6 engines, and weighs the same, or slightly less, as well. Who besides racing leagues and internet "engineers" gives 2 damns about internal displacement anymore anyway?

          I love me some LS engines, but I'll play devil's advocate. The 6.2 L MB engine in the SLS AMB Black is something fierce, but I admit I have no idea how reliable it is, its tuning possibilities, or its maintenance costs and ease of maintenance. The V8 and V12 engines by Ferrari are wonderful but require great care. The Porsche and Audi V8 and V10 (naturally aspirated versions) sound amazing. In fact, the Porsche V8 and V10 in the 918 and CGT might be as reliable as the LS, but you can bet they still require great care. I don't know if you can fix an LS with a hammer, as Jay Leno says, but it's simpler and, as an engineer -- doesn't matter what kind -- one of our principles in design is K.I.S.S. (Keep It Simple Stupid).

          The AMG V8 comes to mind. Although I've never driven any American car with the 7.0, my C63 simply crushes the other LS engines just because of the low end torque.

          I agree on all points. There are many awesome engines out there. MBs engines are towers of power, Ferrari engines enough headline a symphony, and Porsche gets more power out of their relatively tiny engines than they have any right to. But, I'll remind you; not only is the LS engine much cheaper (An LS3 crate engine costs around $7.5-8K) but is physically smaller, and significantly lighter than any of those, including Porsche's flat 6. Meaning it can be mounted in a smaller engine bay, lower, while adding less weight... something many American cars need badely! As far as the C63 goes... there's really no "good" response I have to that... that thing is a beast! But, it still comes down to weight and cost; an LS7, fully assembled, with every accessory attached and fluid filled, is about 450 lbs... the same as the M156 Longblock, dry... and I think we both will agree, the LS probably has the edge in lower price to :) Now, after all this talk about engines, power, and sounds... I really wanna go play some Forza :P

        You fail at understanding what displacement does and more importantly doesn't do. And using less fuel? Yeah? Where did you get the idea this engine isn't efficient?

      I'm just amazed at what other carmakers have to do just to keep up with the Nissan GTR. And the Z28, @ 0-60 in 3.7 secs. is still slower than the GTR. Oh, and have they figured out how to keep the tires glued to the wheels?

      I know nothing about cars but wow 650/620 sounds hella fun.

      I wonder if that is to the tire or motor. I suppose motor due to the fact they are quoting 505 stock.
