As if the power picture couldn’t get any better, a company like Vortech with its great reputation for making power comes up with the V-3 Si supercharger for the sixth-gen Camaro. The V-3 Si (“I” for improved) means a vastly improved V-3 for already fast/quick sixth-gen Camaros. The V-3 Si, available in black, satin, and polished finishes, employs a patented oil control system and centrifugal compressor to generate plenty of power without excessive amounts of destructive heat normally associated with superchargers.
What these refinements mean for you is a clearly better centrifugal supercharger that can be installed on your Camaro over a weekend. Vortech tells Chevy High Performance its centrifugal superchargers make more power than comparable Roots-style blowers via greater pressure, yield better flow, and hooks up via an aggressive cog belt. Translated, that means lots of boost and without belt slippage.
It is virtually impossible to show you every step in a V-3/sixth-gen Camaro installation. However, we’re able to illustrate the highlights of what you can expect. Make no mistake, this is not a simple undertaking, which is why we stress following Vortech’s instruction manual closely. As installation instructions go, Vortech’s manuals are among the very best.
Responsibly installed and properly maintained, Vortech supercharger systems are performance-enhancing systems. In most cases, and with a healthy engine, increases in torque of 30-35 percent and horsepower between 35-45 percent can be expected with the boost levels specified by Vortech Engineering. This means keeping boost levels conservative going in and getting a professional tune before mashing the throttle. If there is any sign of detonation under hard acceleration it is strongly suggested you find and correct the reason for the detonation before operating your Camaro any further.
Tuner Kits are also available for the sixth-gen Camaro V-3 Si package. However, Vortech strongly recommends custom dyno tuning with these kits. We will tell you there’s no substitute for a professional tune by a qualified tuner with the proper education and a lot of experience. CHP

1. Installation begins with disconnecting the negative ground cable from the battery, which is located in the trunk area behind a small panel door on the right-hand side. Here, we’re removing the front fascia to gain access to the area in front of the radiator and air-conditioning condenser. You’re also going to have to remove the aero shield underneath. Expect to have to remove and disconnect various components like the horns, behind the fascia.
2. Next, the left-hand (driver-side) headlight assembly is removed to make way for the discharge duct installation.
3. The huge Vortech charge cooler is mounted here, in front of the radiator and air-conditioning condenser and is attached to the front bumper supports. Once in place, you will hardly know it is there.
4. Once the Vortech charge cooler is installed, we’re reinstalling the factory bumper support crossmember.
5. The Vortech V-3 Si supercharger will be installed in this location on the driver-side above the air-conditioning compressor. What this means for you is an easy installation without having to remove accessories, brackets, and other items from the front of the engine.
6. The V-3 Si installation begins with the mounting plate and spacers directly tied to the engine. These pieces are born from billet steel. Shown here is the mounting plate A, which is the first plate installed.
7. The V-3 Si’s forward-mounting plate is bolted through the spacers into the driver-side cylinder head. Shown here is the secondary drive jackshaft. Once these mounting plates and spacers are secured, we’re ready for the V-3 Si installation.
8. This frontal view of the mounting plates and spacers illustrates the V-3 Si’s resting place. The good news here is how easy this mount is to install.
9. The V-3 Si mount installation continues in earnest with the secondary jackshaft to handle the load, which obviously utilizes aggressive cogs for solid traction. This means zero slippage and no power loss.
10. What makes the V-3 Si different is positive belt traction thanks to a 34-tooth drive pulley yielding greater traction than ever before. Here, we’re finishing up hardware installation. Did you remember to use a thread locker on these bolts?
11. The V-3 Si drivebelt adjustable idler pulley is installed next. This pulley rides the backside of the supercharger drivebelt.
12. Slide the cog belt over the supercharger pulley and the jackshaft pulley. Once in place, adjust the idler to apply tension to the cog belt. The proper amount of tension should allow you to twist the straight section of the cog belt one quarter turn.
13. Next are the V-3 Si discharge ducts between the diffuser and the charge cooler, which are routed through the radiator support beneath the driver-side headlight module.
14. The discharge duct to the charge cooler has been installed. It is important to be sure the discharge duct doesn’t come in contact with the headlight module.
15. The Vortech mass air sensor is installed next using the Vortech-provided hardware.
16. The discharge ducting is completely installed. Reinstall the transmission cooler shroud using the Vortech bracket. Install items like the horns and front fascia.
17. We’re on the home stretch of our V-3 Si installation. The engine cover is removed for installation of the new Vortech MAP (manifold air pressure) sensor.
18. Our Vortech V-3 Si installation is complete and looks sharp. The front fascia’s electrical connections have been reconnected and the fascia reinstalled.
19. Vortech recommends to change the engine oil at the factory recommended intervals and to change the supercharger oil every 7,500 miles after the initial change following 2,500 miles.
20. At East Coast Supercharging in Cream Ridge, New Jersey, we strapped our stock Camaro to the chassis dyno where it made 422 hp and 452 lb-ft. With the V-3 Si supercharger bolted up, it made 550 hp and 510 lb-ft of torque at 8 psi boost.
