Welcome to the Overkill supercharger system for you 2012 to 2015 Camaro 3.6 V6. As GM V6 specialists, we see it as our job to take your V6 Camaro to new performance levels and and the Overkill supercharger system can be a game changer for your V6 Camaro.

It's a simple concept, put more air into the engine then it could naturally ingest, match it with the right fueling, and make more horsepower. On the LFX 3.6 V6 found in your 2012-2015 Camaro, this base kit will typically provide over 100 wheel horsepower gain on our base kits with 8psi of boost, providing power numbers of a modern V8 with a weekend's worth of work. Power can be improved well beyond the base kit with our Stage 2 and Stage 3 kits, and other modifications such as exhaust work.

This system is 100% bolt on installation you can do in a weekend. You are not required to have any other modifications on your vehicle. Every requirement to install a supercharger on your Camaro V6 is included in this kit, including going above the normal expectation with our catch can system to improve engine operation and lifespan, and our all inclusive tuning service.

All kits include the following components and features:


You have one choice to make before checking out, regarding our Overkill tuning service: HP Tuners Pro vs Autocal Handheld. Use this guide to help you decide!

HP Tuners Pro - This is a tuning suite that runs on a windows based laptop computer and connects your laptop to your vehicle with a cable. Overkill renders all the tuning for this supercharger kit, you're simply required to use the software to read and write the tunes to your vehicle, and provides scans, all of which is handled through email exchange. You do however have the ability to make your own adjustments, though it is recommended you do not alter our settings unless you have sufficient experience and knowledge to do so. This setup will require a back and forth transfer of files before you have your initial supercharger tune.

Autocal Handheld - This is a handheld tuner that will read, write and scan your vehicle's computer without requiring a laptop. You'll need a windows based PC or tablet with USB connection to transfer files on and off the Autocal. You won't be able to make any tuning adjustments yourself, all tuning will be handled by Overkill. Your Autocal does have the ability to be a code reader, you have the ability to take your handheld with you in the vehicle wherever you go and it can hold several tune files at one time. Your Autocal will come with a base supercharger tune file ready to load when you do your initial installation.

Stage 1 Kit Information

Our base kits come set up with 8-9psi of boost. They can be installed on a completely factory 3.6 V6 and see a 100 horsepower gain. You do not need any modifications on your vehicle to install Stage 1, comes with everything you need. Aftermarket exhaust work is beneficial but not required.

Stage 2 Kit Information

Our Stage 2 kit provides improved performance with more boost, and the required fuel system modifications to support it. A factory GM ZL1 fuel pump is a direct replacement to the factory V6 fuel pump and will provide sufficient fuel flow to the engine. The fuel tank must be dropped for installation, not difficult, but an advance installation for driveway installers. Once installed however, it's matched with a smaller supercharger pulley to increase boost to 10-11psi, providing a 30-40 horsepower additional gain over the base kit. Exhaust work is beneficial and recommended but not required.

Kits start at $5999 for existing Overkill Tune Users, $6499 and up to purchase with Overkill Tuning and Autocal Handheld or HP Tuner Suite Pro!

Optional but highly recommended is this wideband air/fuel meter kit. The purpose of this is to improve the quality of the Overkill tuning service. The wideband meter is an O2 sensor that's accurate to air/fuel readings while under heavy throttle, unlike the sensor GM uses on the Camaro. Simply install in the tailpipe, run the wiring into the cabin, plug the power into the outlet, and plug the sensor input into the HP Tuner cable or Autocal handheld. Overkill will now be able to read your air/fuel ratio coming out the tailpipe and adjust, just like a dyno quality tune. No permanent modifications to the vehicle, there is a deposit only to rent that's fully refundable when you send back the equipement in the fully functional and cosmetic condition you received it.

Deposit of $200 - Fully Refundable






This is an upgrade kit for those in search of improved performance over the base kit. The base kit will run roughly 8psi of boost and is 100% bolt on friendly. In order to run more boost, a fuel pump upgrade is required. This Stage 2 kit adds a bolt in GM fuel pump upgrade to allow you to run more boost and not run out of fuel. A smaller supercharger pulley will produce 10-11psi of boost, very simple. The pump will require dropping the fuel tank for installation, or cutting an access panel from inside the vehicle. You must install the pump to run the smaller pulley! Purchase the Stage 2 kit with the main drop down menu if purchasing with the supercharger kit, or come back later and use the purchase option below to upgrade your current Overkill kit to Stage 2, easy!

Our supercharger system features our quick change pulley system, where our hub gets pressed onto the supercharger shaft and the pulleys bolt to the hub. This allows you to change out your pulley size with ease by undoing the 4 bolts and loosening the belt. Changing your pulley size changes the drive ratio of your supercharger, and this of course changes your boost pressure. We offer you the option to purchase different pulley sizes to suite your interests. Be sure to completely understand the requirements to run each different pulley size. All 3.1" and 2.95" pulleys come with a Gator Grip tooth pattern to the ribs on the pulley surface which helps the belt grip and further reduces the chance of slip.

Frequently Asked Questions

Q: What's a detailed list of what's included in this kit?
A: Kit includes the following items Can I use my existing catch can, why is yours special?
A: We include our catch can system and require you to use it for your own benefit. The internal canister uses a highly effective, patent pending design, however the set up of the system is vital for supercharger use. While most systems just tie into the manifold (dirty) side of the PCV system, ours tie into both the clean and dirty side. While most systems will become completely ineffective when the intake manifold is pressurized with boost, ours closes via a check valve and uses the suction source from the supercharger inlet to continue to evacuate the crankcase. And as a triple backup, our kit uses a clean side separator, which separates oil vapours if the pressure needs to evacuate out the clean side tube for any reason. All of these important features will prevent oil from getting into your supercharger, your intercooler, and into the engine air stream.

What power gains can be realistic to expect?
A: Factory horsepower on a dynojet is typically around 260 wheel horsepower (measured at the wheels). Our base kit is set up to produce 8psi of boost at peak. You can anticipate your kit making around 360-370 wheel horsepower with no other modifications to the vehicle, and upwards of 400 wheel horsepower with additional exhaust and intake manifold modifications. Stage 2 with 10-11psi of boost aims to add roughly 40 horsepower over these figures, so anticipate up to 440 wheel horsepower with recommended aftermarket exhaust modifications. We will work on additional supporting modifications to bring power increases upwards of 500 wheel horsepower with reliable results.




Independent Belt System


One of the things we wanted to ensure as part of our design was an independent supercharger belt system. Rather than using the factory OEM accessory belt, our system uses its own supercharger belt and leaves the factory belt completely intact.

We do this by first installing our new crankshaft pulley. Removing the crankshaft bolt allows you to slide the new pulley as an insert into the factory pulley, and then secure with the bolt. The new pulley indexes into the spokes of the OEM pulley so it is locked into place and cannot slip.



The supercharger is spaced appropriately not just for its own belt but for an 8-rib belt. Rather than using the 6-rib factory belt, a wider 8-rib belt will reduce belt slip issues as we start to get smaller and smaller on the pulleys. We can do this because we are not limited using the OEM accessory belt, this can only be accomplished with a dedicated supercharger belt.



Quick Change Pulley System


We have developed a quick change pulley system for the Vortech supercharger. This means we can run our own pulley sizes and is part of the 8-rib conversion. It also means you can change your pulley sizes very easily. Due to the spacing built into our system mounting plates and the new supercharger positioning, you can access and change the supercharger pulley in a matter of minutes, simply by removing the 4 retaining screws and removing the belt. In smaller pulley sizes, we have a Gator Grip tooth pattern to the ribs of the pulley that will provide the belt additional grip on the pulley but not wear out the belt prematurely.


Front Mount Intercooler


One item that we decided to include standard rather than have as an upgrade is the intercooler. It is important to understand that all intercoolers are a flow restriction to some extent, and their size plays an important role in cooling and flow capabilities.

Our air to air intercooler uses a 24 inch long core (side to side) and 4 inch deep. This is longer and thicker than what used to be the standard for a Camaro supercharger kit. The longer the airflow stays in the heat exchanger, the better the cooling. The extra thickness provides larger air passages which improves flow capability, which will make the supercharger boost more efficient at reaching the engine. This core fits with only minor trimming of some of the plastic shroud around the radiator.


Supercharger Specific Catch Can System


Our Catch Can System included with each supercharger system is set up specifically to perform with forced induction. Unlike a generic catch-can which connects between the intake manifold and engine on the "dirty side" of the PCV system only, ours connects to both sides of the PCV and provides two suction sources for the dirty side crankcase. When the intake manifold becomes pressurized, the catch can looses suction from the manifold, and the crankcase can become pressurized with boost pressure; our catch can uses a check valve to close and prevent boost from pressurizing the catch can, and a secondary suction line connected right before the supercharger inlet actually uses the vacuum created by the supercharger to continue to draw air from the crankcase. As an extra backup, a clean side separator attached to the oil filler cap separates and prevents oil vapors flowing down the clean side line into the intake path. The entire system means that oil will stay out of the supercharger inlet, out of the intake manifold, out of the intercooler, and reduces blowby at the piston rings, all of which improves engine safety, supercharger lifespan, and overall performance.
