Chad McCammon’s Record-Breaking Supercharged Fifth-Gen Camaro

Superchargers have been around for a long time, and by 2013 there certainly are many options out there—most of which are a far cry from the work of Francis Marion Roots and company. However, oddly enough, the latest craze has been sort of a return to the original design, but with a twist (see what I did there?). The latest generation Twin Vertices Series superchargers use two four-lobe rotors twisted to 160-degrees of NVH reducing and stump-pulling perfection. It's the ultimate combination of performance, civility, and reliability in a belt-driven air pump—no doubt why the factory uses this very method in modern supercars.

For those like Chad McCammon and his 2010 Camaro SS, the TVS blower can be the perfect modus operandi for an aftermarket variant of today's modern supercars like the ZL1. In fact, this was his inspiration for building the '10 Camaro, a combination of impatience (waiting for the 2013 ZL1 to be released) and the desire to surpass its performance with the help of Jeff Nance at Speed Engineering. So it should come as no surprise that Jeff and Chad decided to enlist the help of Edelbrock's own spin on the TVS2300 supercharger for a combination that would nearly hit 800-rwhp on 93-octane pump gas alone. That's right, no race gas and no methanol injection – just the average street corner swill. And they didn't even need some aftermarket block and big-block-size cubes to do it.

Starting with the Edelbrock E-Force supercharger system, Speed Engineering put together an engine combination that would make the LS3 better suited for boost, and in the process managed to build the most powerful E-Force equipped car to date. The stock LS3 was yanked so Jeff could start from the ground level, and discard the stock connecting rods, crankshaft, and pistons for much stronger components. A fresh hone on the cylinders plus a Callies forged, 4-inch-stroke crank upped the displacement to 417 cubic-inches. Wiseco dished pistons and Compstar rods complete the rotating assembly, helping to bring the compression to a more detonation-resistant 9.6:1, when paired with the stock LS3 heads.


This no-nonsense build retained as many OEM parts as possible for reliability, while upgrading the critical areas for max power. The heads, for example, have been heavily massaged and upgraded with lightweight valves and Comp Cams valvesprings. The valvetrain also benefits from chrome moly pushrods and Yella Terra rocker arms to match a custom-grind camshaft. Big 2-inch American Racing headers with a 3-inch X-pipe, high-flow cats, and Magnaflow race pipes eliminate any restriction in the exhaust. On the other end of the combustion process, 93-pound injectors and twin in-tank Fuel pumps from Livernois deliver all the pump gas the 417 can handle. And Speed Engineering's upgrades to the intercooler make the most of the 93-octane.

Thanks to the 2300cc TVS supercharger, the E-Force system can push a lot of air, but it is generally limited to the 700 Rear wheel horsepower range due to the runner size. Speed Engineering credited the tuning and a great combination of components for surpassing the current record, squeezing 793 horsepower out of the LS3 on pump gas! Peak torque figures of 790 lb-ft came in before 4,000 rpm, and it's interesting to note that Chad's Camaro makes 700 lb-ft of torque at 2,500 rpm.


With intentions of mostly street activity, the stock Tremec six-speed manual transmission is still in service, as is the stock independent Rear end with 3.45 gears. However, with that amount of power (as you'd guess) the clutch has been upgraded with Hendrix Engineering's Street Slayer twin carbon disc bad boy—combining holding power and polite street manners. A few pieces from BMR Suspension also do their part in keeping the driveline intact by reducing axle-breaking wheelhop.

Aesthetically, Chad's Camaro has a sinister look, thanks to a BMR one-inch lowering kit and black-spoked CCW 505a wheels with matching Nitto Invo 275 and 315mm Tires. The lowered stance is complemented by a variety of body accents, including a custom Front valance and side skirts, painted to match the original black body color. Similarly, the interior is all-business, the only modifications are the boost and wideband gauges, mounted in an A-pillar gauge pod.

An aggressive attitude that starts with the stance and ends with tire-hazing torque, Chad's Camaro certainly puts a new spin on the modern supercar and pulls several car-lengths on the ZL1 at nearly 800-rwhp. "Driving the car is just incredible–the power is there instantly when you touch the throttle." Even at 4,200 pounds, the Camaro is snappy and quite responsive, and it annihilates the Tires at will.

The car has yet to see any track time, but Chad plans to install some drag Tires and wheels and give it a shot. For now, though, he's enjoying big-time power on the street, and likely showing his taillights to ZL1 owners on a regular basis.
