Yes, you can install a nitrous oxide system (often called NOS or just nitrous) on a supercharged car. This combination, known as forced induction stacking, can produce immense power gains. However, it is an advanced and high-risk modification that requires significant supporting upgrades and a professional, custom tune to prevent immediate and catastrophic engine failure.
The primary challenge is managing the extreme cylinder pressure and heat. Both a supercharger and nitrous oxide force more oxygen into the engine, but they do it differently. The supercharger provides a constant boost, while nitrous delivers a massive, short burst of oxygen and fuel when activated. This sudden spike can easily exceed the mechanical limits of your engine's internal components like pistons, connecting rods, and head gaskets.
To do this safely, virtually every part of the engine's fuel and ignition systems must be upgraded. This includes high-flow fuel injectors and pumps to deliver the necessary extra gasoline, stronger forged internal engine components to handle the stress, and a more aggressive cooling system, like an upgraded intercooler, to manage the intense heat. The most critical element is the engine tune. A generic, off-the-shelf tune will not work; it requires a custom dyno tune by an expert to ensure the air-fuel ratio and ignition timing are perfectly calibrated for the combined boost.
The table below outlines some key considerations and potential power gains for a well-executed setup on a typical V8 engine.
| Consideration | Details | Supporting Modifications Needed |
|---|---|---|
| Engine Internals | Stock cast pistons/rods are prone to failure. | Forged pistons, connecting rods, and high-tensile head studs. |
| Fuel System | Demand increases dramatically. | High-flow fuel pump, larger injectors, and dedicated nitrous fuel line. |
| Engine Management | Critical for preventing detonation. | Standalone ECU or professional custom tune on stock ECU. |
| Cooling | Combustion temperatures soar. | Upgraded intercooler, high-capacity radiator, and colder spark plugs. |
| Power Gain (Est.) | A "sane" 75-100 hp nitrous shot on top of 8-10 psi of supercharger boost. | Can push a built engine to over 800+ wheel horsepower. |
Ultimately, this is a project for experienced builders with a deep budget, not a weekend DIY install. The potential for power is incredible, but the risk of a melted piston or a blown head gasket is always present.

As a guy who's blown up an engine learning this lesson, my advice is simple: you can, but you'd better build the motor first. Slapping a nitrous kit on a stock supercharged engine is a fantastic way to turn it into a very expensive boat anchor. The supercharger is already stressing the bottom end. The nitrous is like a sledgehammer hitting it. If you're not ready to invest in forged internals and a pro tune, just enjoy the power you have. It's cheaper than a new engine block.

Technically, it's possible, but the hurdle is immense. You're combining two methods of forced induction, creating a huge thermal and pressure load. The engine control unit (ECU) must be meticulously recalibrated to handle the transient fuel and timing demands when the nitrous activates. Without that precision, detonation—uncontrolled explosive combustion—will destroy the engine. This isn't a modification; it's a full engine rebuild project centered around reliability under extreme stress.

Think of it this way: your supercharger is like a strong, steady tailwind for your engine. Nitrous is like lighting a jet-fueled rocket booster for ten seconds. The key is making sure your car can handle the sudden, explosive shove without breaking apart. This means your fuel system has to be a firehose, your engine parts need to be forged steel, and most importantly, a tuning expert has to make sure the rocket ignites at the perfect moment. It's a wallet-draining endeavor, but the results are breathtaking if done right.

From a pure performance standpoint, yes, it's the ultimate power adder. The goal is to use the supercharger for your broad, everyday powerband and the nitrous for a massive top-end punch at the drag strip. But the cost is prohibitive. You're looking at thousands for the nitrous kit, then thousands more for forged internals, a fuel system, and custom tuning. For most people, upgrading the supercharger pulley or adding a larger intercooler is a safer and more cost-effective path to more power.
