Welcome to the Overkill supercharger system for your 2010 to 2015 Camaro 3.6 V6. There's a lot of information packaged into this page so keep scrolling down for more information.

The Overkill supercharger system featuring Procharger superchargers answers the question on how you make V8-like horsepower with your 3.6 V6. Whether you've owned your 5th gen Camaro V6 for a long time or a new owner, you had specific reasons for getting the V6 and now you're ready for more! The age-old concept of pressurizing intake flow with a supercharger works great with these new-age Direct Injection V6s and Overkill is proud to be the only source for a bolt on forced induction system for your 5th gen Camaro V6.

This system is a bolt on installation with no permanent modifications to your vehicle and 100% reversible. You are not required to have any other modifications on your vehicle for the Stage 1 kit and all Stages are designed to work with a factory 3.6 engine. Every item to install the supercharger on your Camaro V6 is included in this kit, including going above the normal expectation with the catch can system and tuning service, wiring adapters, fabricated brackets etc. What Overkill doesn't fabricate, top quality components are sourced such as the Procharger brand head units used in all systems.

All kits include the following components and features:

New for September 2020 - Switch to Procharger!

Overkill is excited to announce the switch to Procharger head units for this supercharger system. Stage 1 and 2 come with a P series Procharger while Stage 3 comes with a D series that you can anticipate high horsepower potential from when pushing beyond our Stage kits with additional modifications. Read below to understand the difference in Stage kits and what might be right for you!

**Updated February 2021**

Stage 1 - 8 psi - 350-370 wheel horsepower anticipated (factory 245-260 wheel/chassis dyno horsepower). The base Stage 1 kit is extremely popular, it'll bump up performance on a completely factory engine and requires no fuel system upgrades. Upgrades to the exhaust system are recommended but not required, 91 octane or higher pump gasoline is required. Stage 1 uses a P1SC Procharger that's designed to build mid-range boost fast to improve torque and also provide high rpm horsepower gains.

Stage 1.5 - 9-10 psi - 370-400 wheel horsepower anticipated. Stage 1.5 ontop of the base Stage 1 adds: A fuel pump upgrade is the minimum requirement to increase in boost to around 9-10psi. Stage 1.5 retains the P series Procharger. Exhaust work is now highly recommended.

Stage 2 - 10-11 psi - 390-420 wheel horsepower anticipated. Stage 2 ontop of the base Stage 1 adds: Stage 2 adds the fuel system upgrades of Stage 3 while maintaining the P series Procharger. Both LLT and LFX engines benefit from a fuel injector upgrade to go with a fuel tank fuel pump upgrade, while LFX models also receive a high pressure fuel pump upgrade as well (this is the fuel pump at the engine). A smaller pulley increases boost to 10-11 psi while maintaining the P1SC supercharger. Exhaust work is now highly suggested, as is finding 93-94 octane pump gas when possible. With flex fuel enabled, E85 is possible to run on the Stage 2 LFX models. While pushing more boost, this is still a very comfortable reliable range for a 3.6 engine.

Stage 3 - 11-12psi - 410-450 wheel horsepower anticipated. Stage 3 ontop of the base Stage 1 adds: Stage 3 is the upgrade to a D1SC higher output Procharger that will make a minimum of 10-11psi and can support up to 18psi on built motors. Included are all the fuel system upgrades from Stage 2 as well. Not only will the Stage 3 provide a taller ceiling for making power beyond these Stage kits with further upgrades, but the D series will also improve horsepower in the 10-12psi range by using a large pulley and not requiring as much horsepower from the engine to be driven vs the P series.

*Special note* - The D-series upgrade is ONLY available at this price when purchasing the Stage 3 kit on the original upfront purchase. Upgrading your Procharger unit down the road is available but at a much higher pricepoint, so if you think you'll want this upgrade, now's the best time to consider it!

Update July 12, 2021: Production delays have forced these supercharger kits out of stock since April. Work is continuing to bring kits back available by the end of summer. As of today, I've been able to produce ONE more full kit including a P-series Procharger in stock, available to make into Stage 1 or 2 configuration. If you've been hoping to order a kit, here's your chance! Kit will ship in roughly 7 days after ordering as only final assembly is required, all parts in stock. Please email willoverkill@gmail.com with any questions before ordering, this is first come first serve however, if you get a sold out message while checking out then sorry the kit is already sold.

Question: What Power Gains Are Expected?

Answer: Stage 1 adds roughly 100 horsepower measured on a chassis dyno at the wheels (about 125 at the engine), so essentially your 320 horsepower engine from the factory rating will become a 450 engine, with no other changes. Power gains are quoted above with each Stage upgrade. Additional power can be made with methanol injection, MACE camshafts, exhaust work, porting the intake manifold, and more. The factory 3.6 engine is proven durable in the 12psi and 450 wheel horsepower range.

Question: When Should I Get Stage 3 With The Larger Procharger?

Answer: The larger D series will provide more headroom for those who want to persue more boost pressure than 10-12psi, and so it's ideal for those who will add more modifications over these Stage kits. In addition, the larger supercharger running a larger pulley and turning slower to make the same boost pressure will absorb less power from the engine and in turn you'll make more power at the wheels, upwards of 20 wheel horsepower at this Stage's boost level. If you want to maximize the gains from the kit, if you plan to run extra modifications like water/methanol injection and/or MACE camshafts, just as some examples, the Stage 3 D series is a worthwhile investment.

Question: Do I Need To Do Anything To The Car First Before Installing?

Answer: Stage 1, no, nothing else NEEDS doing, Stage 2 it's recommended to have exhaust work, Stage 3 is required to have exhaust work and suggested to have other modifications. On Overkill's personal Cadillac 3.6s, I have no other modifications done to the vehicle, only what is included in the Stage 1 kit, and it was plenty enough power for me. If you have higher mileage, consider doing a full set of ignition coils during install is smart, you can search for "D515C" on ebay, amazon or rock auto; you can also get yourself a replacement serpentine belt for the accessory system if you're higher mileage; while not impossible to change after the supercharger install, much easier to do it now before the install. Lastly is you should be all up to date on your servicing, including changing your transmission oil and differential oil following "severe" service intervals, which typically call for replacement every 45k miles. For your engine oil, it is very highly recommended that you use synthetic oil if you're not already. You're absolutely 100% required to run 91 octane gasoline or higher.

Question: How hard is it to install?

Answer: Straight forward bolt on system. Lots of loosening and tightening bolts, lots of paying attention to detail, very little cutting, very little fabrication. All of the works is done either from the top of the engine bay or in the front bumper area, nothing on your back under the vehicle. A professional shop can install this in 6-8 hours but will likely quote and charge 10-12. A good DIYer can get this done in a weekend.

Question: How Reliable Is This Setup?

Answer: The 3.6 engine has proven itself durable on a supercharged setup. Overkill's been supercharging the 3.6 since 2016 and know the ideal targets of boost, limits of fuel capacity, ideal air/fuel mixture, spark timing etc, to build durable and lasting setups. The supercharger system is also proven reliable, engineered with durable custom components and matched with top quality off-the-shelf components. Aside from oil changes on the supercharger, the goal is to have you install this system and enjoy it without the need for constant attention to any component. You can anticipate being able to daily drive the setup.

Question: Is there ANYTHING Special To Know About This Setup?

Answer: Due to the construction tolerances, Procharger recommends idling the engine and supercharger to warm it up in winter months and keep the rpms below 2500 until the engine is warm. Currently, the Procharger will require removing to change its oil until a drain system can be engineered; 6000 mile oil changes are suggested by Procharger.

Question: I Already Have Overkill tuning, Can I buy without the HP Tuners?

Answer: If you have Overkill tuning through the HP Tuner system, you can select to purchase without the HP Tuner. If you have Overkill tuning through an Autocal, it's possible to tune through the Autocal for Stage 1 but requested that you switch to HP Tuners and to that end a rebate on sending back the Autocal will be offered, email to discuss before purchasing.

Independent Belt System

One of the most important design elements is an independent supercharger belt system. Rather than using the factory OEM accessory belt, the Overkill system uses its own supercharger belt and leaves the factory belt completely intact. The new piggyback crank pulley indexes into the spokes of the OEM pulley so it is locked into place and cannot slip. It provides a wider 8-rib belt for the supercharger pulley to reduce the chance of belt slip. The supercharger, if ever needed, can also be easily disabled without having to affect the main accessory belt system.

Large Front Mount Intercooler

One item that Overkill decided to include standard rather than have as an upgrade is the largest intercooler that could fit in front of the radiator. 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. This 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 more air passages which improves flow capability, which will make the supercharger boost more efficient at reaching the engine.

Catch Can System

Most other supercharger systems for other vehicles don't provide a catch can. It's an essential component to run a catch can on these styles of supercharger systems, to keep oil out of the supercharger system as well as the engine. On other systems, Will Overkill has literally witnessed engine oil being blow out of the blow off valve; this is oil that will be coating the internals of the supercharger, intercooler and its piping. The catch can system provided will catch the majority of this oil, keeping the intercooler clean inside and perform to its capability. In addition, the catch can system is set up to continuously evacuate the crankcase with vacuum, rather than operate on the presumption that there will be positive crankcase pressure when the intake manifold pressurizes with boost. Furthermore the system is a closed loop operation, there is no atmospheric venting within the system to relieve boost pressure, the system is designed to contain the PCV system to the engine and intake stream.

Purchasing Agreement

By purchasing and installing this supercharger kit, you the buyer understand and agree to the following:
  • Buyer assumes all risks associated with adding an aftermarket performance part of this significance to your vehicle, including but not limited to the increased acceleration rates, potential for higher road speeds, the increased risk of mechanical wear and failure of existing components on your vehicle. No warranty for your vehicle is expressed or implied.
  • The warranty on the Procharger head unit is limited to the terms of the manufacturer's warranty for 1 year from its construction (ordered at the time of your purchase).
