Not all supercharger kits are created equal. Choosing the wrong kit for your car—or for your goals—can lead to wasted money, tuning headaches, or even engine damage. That’s why doing your homework before you buy is essential.
This buyer’s guide will help you understand the key factors that go into selecting the right supercharger kit for your build.
Understand Your Performance Goals
• Before you shop, ask yourself: What am I trying to achieve?
• Daily Driver / Mild Build: If you want a little extra punch without sacrificing reliability, look for entry-level kits designed for stock engines at 6–8 PSI.
• Weekend Warrior: If you plan to hit the track occasionally, you may want a kit that supports more boost and offers better cooling.
• Dedicated Race Car: High-boost kits with intercooling and stronger fueling support are a must.
• 👉 Having clear goals prevents overspending—or underbuilding.
Choose the Right Type of Supercharger
• There are three main types of superchargers, each with pros and cons:
• Roots (or Twin-Screw): Delivers massive low-end torque and instant boost. Great for street cars and muscle cars.
• Centrifugal: Similar to a belt-driven turbo. Makes more power up high and is usually more efficient. Common for imports and high-RPM builds.
• Twin-Screw: Like a Roots blower but more efficient. Provides strong torque with less heat.
Consider Supporting Mods
• A supercharger kit is only as strong as the parts around it. Some kits include everything you need, while others assume you’ll upgrade supporting mods separately.
• Fuel System: Bigger injectors and pumps are often required once you go past 6–8 PSI.
• Cooling: Intercoolers (air-to-air or water-to-air) help control intake temps.
• Tuning: Make sure you have ECU support for your platform. Many kits include base maps, but professional tuning is highly recommended.
• Drivetrain: Can your clutch, transmission, or differential handle the extra torque?
Street vs. Track Considerations
• Where you drive matters just as much as what you drive.
• Street Builds: Prioritize reliability, drivability, and fuel economy. Look for kits designed for pump gas.
• Track Builds: Prioritize power consistency, intercooling, and fueling capacity. Water-to-air intercoolers and ethanol compatibility are common in race setups.
Budget Wisely
• Supercharger kits range from around $3,500 to $8,000+, depending on the platform and level of completeness.
• Entry-Level Kits: Perfect for daily drivers who want 40–60% more power.
• Mid-Range Kits: Include intercooling and stronger components for track use.
• High-End Kits: Designed for race cars or big power builds.
• 👉 Don’t forget hidden costs: installation, tuning, supporting mods, and maintenance can add up quickly.
Legal & Emissions Considerations
• If you live in an emissions-regulated state like California, make sure your kit is CARB-legal. Running a non-compliant kit can result in fines or failed inspections.
• Check for EO numbers (Executive Order numbers) that certify a kit’s legality. Many top brands now offer 50-state legal kits for popular platforms.
DIY vs. Professional Installation
• Some kits are designed for DIY installation with basic tools, while others require professional installation and tuning.
• DIY Kits: Usually bolt-on with step-by-step instructions. Great for mechanically inclined enthusiasts.
• Professional Install: Recommended for high-boost or race builds where tuning and fabrication are involved.
• 👉 If in doubt, let a pro handle the install. It’s cheaper than fixing a blown motor.
Conclusion: Choose Smart, Boost Smart
• The right supercharger kit can completely transform your car, delivering instant power while keeping drivability intact. But choosing wisely—based on goals, compatibility, budget, and legality—is the key to long-term enjoyment.
• When you’re ready to take the next step, explore available kits for your platform, read customer reviews, and talk to your tuner about what makes sense for your build.
