Given the recent introduction of the much-anticipated 2010 Camaro SS (we are equally excited about the possibility of a Z28), it seems logical that the vast majority of owners will be interested minor performance upgrades. There will of course, be those who want to take things one step further, and for those enthusiasts of the more serious nature, Vortech offers a bolt-on supercharger capable of supporting as much as 775 (flywheel) horsepower. Naturally, the bolt-on kit for the 2010 Camaro is not supplied at this power level for the stock motor, and instead comes equipped to supply a peak boost pressure of roughly 7.5 psi at 6,500 rpm. This boost comes from a V-3 Si trim supercharger that features a high-efficiency impeller and housing designed in-house on Vortech's own SAE J-1723-compliant supercharger test cell. What this means to the average consumer is that Vortech went to great lengths to certify its test cell to ensure quality components. It is one thing to state efficiency levels and another to have the test procedure recognized and certified by the Society of Automotive Engineers. In addition to the highly efficient impeller and compressor housing, the V-3 Si trim supercharger features an internal lubrication reservoir, making it completely self-contained (no need to punch holes in the oil pan for drain back). Vortech even went the extra mile to provide ease of maintenance by configuring the self-contained supercharger with an oil drain that eliminated the need for removal during recommended oil changes.
The highlight of the Vortech kit for the 2010 Camaro was obviously the V-3 Si centrifugal supercharger, but a complete kit does not a supercharger make. Keeping the elevated charge temperatures cool was an equally efficient air-to-air intercooler featuring three-inch, mandrel-bent aluminum tubing. Additional features included billet aluminum, twin-plate supercharger mounting brackets, an SFI-approved race crank damper, and Max Flow racing bypass valve. The heavy-duty mounting brackets were designed to eliminate deflection that can play havoc on belt tension and life, while the SFI-approved damper included keyed mounting to eliminate pulley slippage. It is necessary to drill and tap the stock crank and damper, but a complete (and easy to use) drill and fixture combination are included in the kit. This is pretty standard in the industry for LS motors, as GM decided to eliminate the damper keyway on the factory cranks. The racing bypass valve is in place to eliminate compressor surge caused by slamming the throttle closed at high rpm and boost levels. The bypass valve provides an escape route for the pressure buildup. Also included in the street kit are a complete fuel management system (injectors, MAF, and ECU reflash), a dedicated 10-rib belt drive system with automatic tensioner, and even a 3-year/36,000-mile limited warranty.

Even in stock trim, the LS3 is a force to be reckoned with on the street. We could do without all the plastic, but underneath beats the heart of a true Bow Tie warrior.

What Camaro owner wouldn't be proud to lift the hood and reveal a shiny Vortech supercharger? Note the roto-molded plastic intake tube and new MAF used on the kit.

Tested on Vortech's own Mustang chassis dyno, the Vortech supercharger kit increased the power output from 281 hp and 277 lb-ft to 425 hp and 383 lb-ft. The 51% increase in power came at a peak boost reading of just 7.5 psi.

Four-digit power levels require a four-digit rotating assembly. ProComp supplied the 4340 forged steel stroker crank and matching 6.20-inch forged rods. Combining the 4-inch stroker crank with the 4.030 bore resulted in a finished displacement of 408 cubic inches.

Note the forged (dished) pistons from Probe Racing along with the ARP head studs and Fel-Pro MLS head gaskets. These three are must-have items on high-horsepower, boosted applications.

Comp Cams supplied a hydraulic roller cam for our LS3-headed test motor. The Xtreme Energy featured 0.624-inch lift, a 239/247 duration split, and a boost-friendly 114-degree lobe separation angle.

In addition to the cam, Comp Cams also supplied a new set of hydraulic roller lifters.
