The 3.6 Pentastar V6 engine has been in production since 2011, and it is one of the most popular engines for vehicles in the Chrysler (Stellantis) lineup. In the Chargers and Challengers, it makes 292–300 horsepower, and the Jeeps get the slightly less powerful 285 horsepower version. However, if you are looking to seriously turn up the wick and get some more performance, adding a 3.6 Pentastar supercharger is an excellent way to go on any model and much easier than a HEMI swap.

3.6 Pentastar Supercharging Basics

Now let’s talk about the basics of adding a supercharger kit to your Pentastar powered vehicle. Before going and purchasing a full kit, it’s important to understand what you might be getting yourself into. Typically, most supercharger builds will need a budget of at least $10,000-$20,000. This includes not just the kit itself, but also installation, supporting mods (like tuning), and other optional upgrades you might find yourself wanting along the way. First, let’s talk about supporting mods for your kit.

Supporting Mods and Tuning

Depending on your build plans for the 3.6 Pentastar supercharger kit, you may or may not want to add additional supporting mods. Some people simply put on a supercharger kit and don’t add anything extra, but most people will add supplemental mods to help the supercharger work more efficiently and ultimately make more power. 

One of the most common upgrades is going to be long-tube headers. Headers are aftermarket exhaust manifolds, and they can free up an additional ~20 wheel horsepower on top of your gains from the blower. Connected to your headers is the cat-back exhaust, and these are also popular upgrades. While they won’t do a lot from a power perspective, they will add a nice deep rumble to your exhaust that increases volume, too.

However, the most important mods you will want to look at are going to be related to the suspension and handling. Adding 150+ horsepower to an otherwise stock car, truck, or crawler will definitely change the handling characteristics. If you’re in a sedan, you might want to look at things like coilovers, lowering springs, and sway bars. If you have a crawler or off-roader, you might want to look more at sway bars, control arms, shocks, and springs.

Brakes and Tires

Of course, you will also want to look at getting better tires and likely some upgraded brakes. Tires are some of the most important but underrated parts of a car’s ability to handle. Remember, 150+ horsepower gains are meaningless if you can’t successfully transfer it from the tires to the pavement with traction. 

Finally, you’ll need to make sure you have adequate stopping power after adding a blower. Your stock brakes might be okay if you have a sport/performance package, but otherwise most stock brakes need to be upgraded to safely handle the extra power. It’s not a question of if you will stop, but how effectively and how long it will take. 

Why is Tuning Important?

Bar none, including all the supporting mods listed above (besides maybe brakes), the most important mod you need to have done if you plan on a 3.6 Pentastar supercharger is tuning. Having a tuner (either online or in-person) give you a map that will make sure your car operates safely and correctly is of paramount concern. Without tuning, your engine will not be able to safely handle the extra air from the supercharger, resulting in lean air-to-fuel ratios and detonation, causing melted pistons/thrown rods/cracked blocks. 

Tuners can optimize your fueling, ignition and cam timing, and boost pressure, to ensure that not only are you making the most power possible, but that your engine can handle it. Finding a tuner who is reputable and has handled your model and modifications before is a great idea, and can only be avoided at your own risk. MAKE SURE YOU TUNE!

Pentastar Block and Internals Power Limits

Now the inevitable next question is how much power can the Pentastar cylinder block and internals (connecting rods, pistons, crankshaft, etc) can take before failing. While there is no magical number, most people would say that going past 450-500 horsepower is about the limits of the stock internals. At that stage, you will want to start thinking about forged pistons, rods, and head studs for reinforcement. 

The block is likely good well past that for another few hundred horsepower before seriously being jeopardized. However, most people who do go over 500-600 horsepower are either race teams with built engines or are using the larger HEMI V8 power plants. So you are in a bit of uncharted waters pushing that with the stock Pentastar. In addition, you’ll also need a custom blower kit, as all of the ones available max out around 450 horsepower.

How much boost can my 3.6 Pentastar take?

Most tuners will keep boost on a stock 3.6 Pentastar to 12-13 PSI maximum. Above 14 PSI and cylinder pressure starts to become an issue, which means knocking and detonation. It is possible to go above 14 PSI, but usually it’s not done on a stock engine. 

Different Kinds of 3.6 Pentastar Superchargers

Now let’s talk about the three different kinds of 3.6 Pentastar superchargers available: Centrifugal, Roots, and Twin-Screw.

Roots and Twin-Screw

Roots and twin-screw superchargers are belt-driven and relatively similar, but they have some important differences. Both of them are usually placed on top of an engine and suck in air through an air intake and throttle body, before it is pushed into the supercharger itself. There, it passes between a series of rotors or lobes on its way through the intercooler and intake manifold and into the engine. 

The difference between roots and twin-screws has to do with the rotors. On a roots blower, the rotors spin in opposite directions which pushes more air into the manifold then it can take – causing positive pressure. The air then becomes compressed inside the intake manifold before pushing into the engine. 

On a twin-screw blower, the rotors spin in opposite directions, but mesh with each other and compress the air between them, where it is then sent into the intercooler/engine. So on roots blowers the air compresses in the manifold, on twin-screws the supercharger rotors actually compress the air. Needless to say, twin-screws are much more efficient and can produce more ultimate power than roots.

Centrifugal

The other option is a belt-driven centrifugal-style supercharger. Centrifugal superchargers look similar to 3.6 Pentastar turbochargers, and sit alongside or in front of the engine rather than on top of it. They use an impeller to draw in air to be compressed in a small compressor housing, called a volute, and the centrifugal force of the air pushes it into a diffuser. 

The diffuser converts the compressed air from low-speed and low-pressure to low-speed but high-pressure. It is then sent to the intercooler, throttle body, and intake manifold, and into the engine.

Centrifugal blowers offer the greatest power potential, but struggle to make low-end torque like a roots or twin-screw blower. Centrifugals are also usually the easiest to fit to an engine, as they are smaller and fit under the hood easier.
