Is it illegal to add a supercharger to a car?
The short answer is no, it is generally not illegal to add a supercharger to a car in most jurisdictions. However, there are some important considerations and potential legal implications to be aware of when modifying a vehicle's engine and performance.
Understanding Supercharger Legality
Superchargers are aftermarket modifications that increase a vehicle's engine power and performance by forcing more air into the engine. While superchargers are legal to install on most production vehicles, there are a few key factors to consider:
- Emissions and Emissions Testing: In many regions, vehicles must undergo periodic emissions testing to ensure they meet environmental regulations. Adding a supercharger may affect a vehicle's emissions profile, potentially causing it to fail emissions tests. Owners should check local laws and regulations before making such modifications.
- Vehicle Registration and Insurance: Some jurisdictions may require that modified vehicles be re-registered or that owners notify their insurance providers about performance upgrades. Failure to do so could result in legal issues or coverage problems in the event of an accident.
- Safety and Road Use: Significantly increasing a vehicle's power and performance can affect its handling, braking, and overall safety. Owners should ensure they can safely operate the vehicle and comply with all traffic laws and regulations.
It's important for car owners to research their local laws and regulations before making any major modifications to their vehicles.
Potential Legal Implications
While adding a supercharger is generally legal, there are a few scenarios where it could potentially lead to legal issues:
- Emissions Violations: If a supercharged vehicle fails emissions testing, the owner could face fines or other penalties.
- Unsafe Driving: Reckless or dangerous operation of a highly modified vehicle could result in traffic citations or criminal charges, depending on the severity of the offense.
- Insurance Complications: Failing to notify an insurance provider about a major engine modification could lead to coverage problems in the event of an accident.
To avoid legal issues, car owners should always prioritize safety, comply with all relevant laws and regulations, and communicate openly with their insurance providers about any significant vehicle modifications.
Can I add a supercharger to my car?
Yes, you can install a supercharger on a stock engine, but there are several important factors to consider: Engine Compatibility: Ensure that your engine can handle the increased power and stress that a supercharger adds. Some engines are designed for forced induction, while others may require modifications.
Is it illegal to modify your car?
Jurisdictions often make modifications illegal if they can create safety issues for the driver of the vehicle, other road users or law enforcement officers. Modifications that affect the roadworthiness and safety of the vehicle itself are almost always illegal.
Can I put a supercharger on a stock engine?
When building an engine for supercharging (other than for racing), it is generally built for low to mid-range torque and power. This is similar to a stock engine. And because a stock engine can be used with a supercharger, it would be just as easy to operate or maintain. This makes it less exotic and more practical.
What makes a car illegal?
On the outside of your car, street legal requirements include ground clearance, emission control systems, tires, brakes, bumpers, license plate, lights, hood, and windshields.
Can you legally supercharge a car?
Superchargers with a California Air Resource Board (CARB) Executive Order (EO) number are considered “street legal” in the states that mandate CARB emissions guidelines.
How much HP will a supercharger add?
A supercharger can increase an engine's power by 50 to 100 horsepower. On the other hand, a turbocharger can increase an engine's power by 70 to 150 horsepower.
How much HP does a supercharger add?
On average, adding a supercharger will give you a supercharged horsepower boost of about 46 percent with 31 percent more torque. That's some neck-snapping gains!
How much does it cost to install a supercharger?
The Cost of Building an EV Charging System Like the Tesla Supercharger
| Cost Element | Average Cost (USD) |
|---|---|
| Hardware and Installation | $10,000 – $50,000 |
| Power Supply and Grid Upgrades | $20,000 – $100,000 |

| Total Cost | $60,000 – $350,000 |
What modifications do you have to declare?
Yes, every car modification must be declared to your car insurance provider. Even changes that seem minor—such as those that don't affect how the car drives or improve safety and vehicle control—still need to be reported.
What makes a car not street legal?
On the outside of your car, street legal requirements include ground clearance, emission control systems, tires, brakes, bumpers, license plate, lights, hood, and windshields.
