The Honda S2000 remains one of the most iconic sports cars of the early 2000s, celebrated for its razor-sharp handling and high-revving F20C (and later F22C) engine. However, even the most dedicated S2000 enthusiast eventually craves more power. Forced induction—specifically supercharging—offers a reliable path to transform the car's naturally aspirated character into something substantially more potent without sacrificing the linear power delivery that makes the S2000 so engaging. This article provides an in-depth look at the power gains you can expect from the Edelbrock E-Force supercharger and other top-tier brands, along with the critical supporting modifications and tuning required to unlock the full potential of your S2000.

Supercharging vs. Turbocharging: Why Go for a Blower?

Before diving into specific kits, it's important to understand why supercharging is the preferred forced induction method for many S2000 owners. A supercharger is mechanically driven off the engine's crankshaft, typically via a belt, meaning boost is available immediately at any RPM. This results in a power curve that feels like a larger, more powerful naturally aspirated engine—no lag, just immediate thrust. Turborcharging, while capable of higher peak numbers, introduces lag and heat management challenges that can alter the car's driving dynamics. For street-driven cars that see occasional track use, a supercharger's linear, predictable power delivery is often ideal.

There are three main supercharger designs: roots, twin-screw, and centrifugal. Most S2000 kits use either a centrifugal supercharger (like Jackson Racing and Kraftwerks) which behaves like a belt-driven turbo, or a twin-screw supercharger (like the Edelbrock E-Force and Comptech), which uses meshing lobes to compress air and provides instant boost across the rev range. Each design has unique characteristics affecting power delivery, heat output, and installation complexity.

Edelbrock E-Force Supercharger: The Premium Twin-Screw Option

The Edelbrock E-Force supercharger is widely regarded as one of the most complete and well-engineered kits for the Honda S2000. Designed specifically for the F20C and F22C engines, it features a unique twin-screw (Eaton TVS) rotor set and an integrated air-to-water intercooler housed within the intake manifold. This design keeps intake air temperatures low, reduces heat soak, and allows for consistent performance during extended driving sessions. The kit includes a high-flow fuel injector upgrade, a reflashable ECU calibration, and all necessary hardware for a clean installation.

Real-World Power Gains with the Edelbrock E-Force

When properly installed and tuned on 91-93 octane pump gas, the Edelbrock E-Force supercharger delivers impressive results. On a stock engine with no supporting mods, owners report wheel horsepower gains of approximately 100-120 hp and torque increases of 80-100 lb-ft. This typically brings the S2000 from around 220 whp (stock) to over 350 whp at the wheels. Some dyno runs have shown as high as 370 whp with a 3.12-inch pulley and premium fuel. The torque curve gains are particularly noticeable, with peak torque arriving much earlier in the RPM band, making the car feel significantly stronger in everyday driving.

It's worth noting that the Edelbrock kit's power gains are slightly more conservative than some centrifugal options at lower boost levels, but the torque response is flatter from 3,000 RPM upward. For a street-driven car that rarely sees the top of the rev range, this is a major advantage. The integrated intercooler also means less power loss from heat soak during spirited driving compared to many other kits.

Installation and Tuning Considerations for Edelbrock

Installation of the Edelbrock E-Force is considered straightforward for a skilled mechanic, but professional installation is strongly recommended. The kit requires no cutting or drilling—it bolts directly to the intake manifold. However, you will need to upgrade the fuel pump to a higher-flow unit (Bosch 044 or similar) to maintain proper fuel pressure under boost. The included ECU calibration is a good starting point, but custom tuning using a standalone ECU (like Hondata or AEM) is recommended to squeeze out maximum power and ensure drivability. Many owners report that a custom tune adds another 10-15 horsepower and improves part-throttle response.

Jackson Racing Supercharger: The Centrifugal Powerhouse

Jackson Racing has a long history of developing forced induction systems for Honda engines, and their S2000 kit is no exception. This is a centrifugal supercharger that uses an Eaton TVS R1320 or similar rotor assembly mounted remotely, with an air-to-air intercooler (or air-to-water on later kits). The Jackson Racing kit is known for its high-quality fabrication and ability to produce very high power numbers with the right supporting mods.

Jackson Racing Power Gains

On a stock engine, the Jackson Racing supercharger typically delivers 70-90 whp gains, bringing the total to around 300-310 whp on low boost (6-7 psi). However, this kit is designed to be highly scalable. With an upgraded pulley, larger injectors, and a high-flow fuel pump, owners can see 110-130 whp gains, pushing to over 370 whp. The centrifugal design means boost builds gradually with RPM, so power delivery is linear, though not as immediate as a twin-screw. This can be an advantage on tight tracks where you want to modulate power more precisely.

Jackson Racing offers both non-intercooled and intercooled versions. The intercooled kit adds a front-mount intercooler and improves consistency during hard runs. On a properly tuned car, the Jackson Racing kit is known for its reliability, with many owners reporting over 100,000 miles of trouble-free operation.

Installation and Tuning for Jackson Racing

The Jackson Racing kit requires more assembly than the Edelbrock unit, as the supercharger is mounted via a bracket and driven by a belt from the crank. Installation typically takes a full weekend for a DIYer. Custom tuning is essential—the supplied calibration is too conservative. Most shops recommend a Hondata FlashPro or AEM Infinity ECU to dial in fuel maps and ignition timing for maximum power. Upgrading the clutch is also recommended, as the stock clutch starts slipping around 320 whp.

Comptech / CT-Engineering Supercharger: The Proven Classic

Comptech Superchargers (now CT-Engineering) were among the first forced induction systems for the S2000, and they remain a solid choice. The kit is a twin-screw (Eaton M62) design, mounted directly to the intake manifold, similar to the Edelbrock. The design is known for its robust build quality and smooth power delivery. Early Comptech kits were non-intercooled, but later versions include an air-to-water intercooler system.

Power Gains and Character

With the intercooled Comptech kit running 8-9 psi, owners typically see 80-100 whp gains, translating to roughly 300-320 whp on a stock engine. Torque jumps by about 60-80 lb-ft, with a strong surge starting at 3,500 RPM. The twin-screw design provides excellent low-end grunt, making the car feel much faster in daily driving. Some owners have pushed the kit to 10 psi with a smaller pulley and race fuel, achieving over 360 whp, but this requires upgraded injectors and a tunable ECU. The Comptech kit is known for its durability—it uses a high-quality Eaton rotor pack that can last tens of thousands of miles with proper maintenance.

Installation and Supporting Mods

Like the Edelbrock, the Comptech kit bolts directly on but requires tuning. The older non-intercooled versions are less tolerant of aggressive timing and should be upgraded with a cooling solution. Many owners retrofit a front-mount intercooler or water-methanol injection to keep intake temps under control. A clutch upgrade is also advisable for any car producing over 330 whp. Professional installation is recommended to ensure proper belt alignment and pulley tension.

Other Notable Options: Kraftwerks and Vortech

Beyond the three major players, Kraftwerks offers a centrifugal supercharger kit similar to Jackson Racing, typically producing 80-100 whp gains on low boost. Their system uses a Rotrex C30-94 centrifugal unit, which is quiet and efficient. Vortech also historically produced a kit for the S2000, though it is now discontinued; used systems can still be found. These kits generally offer similar power levels but may not have the same level of support and refinement as the Edelbrock or Jackson Racing offerings.

Factors That Influence Actual Power Gains

No two S2000 supercharger builds make exactly the same power. Key variables include:

  • Engine condition: Compression, leak-down test results, and valve adjustment greatly affect power. A healthy engine will make more boost and more power reliably.
  • Fuel quality: Premium pump gas (93 octane) is a minimum for supercharged cars. Higher octane (race fuel or ethanol blends) allows more timing advance and boost, yielding up to 20 more horsepower.
  • Intercooling efficiency: Air-to-water intercoolers (Edelbrock, later Comptech) maintain lower intake temps than air-to-air setups, especially during sustained driving. Heat soak can reduce power by 10-20 hp on a non-intercooled kit running back-to-back pulls.
  • Supporting modifications: A high-flow exhaust (test pipe, cat-back) and cold air intake can add 5-15 whp. Upgraded fuel injectors and a high-flow fuel pump are mandatory for any boost over 8 psi.
  • Tuning quality: A well-calibrated tune by a reputable S2000 tuner is the single biggest factor in both power and reliability. A poor tune can cause detonation, limiting power and damaging the engine.
  • Climate and altitude: Boost levels are relative to atmospheric pressure. At higher altitudes, superchargers produce less absolute boost, but power losses are proportional. In hot climates, intercooling becomes even more critical.

Installation and Tuning: A Step-by-Step Primer

Installing a supercharger is a major undertaking that should not be rushed. Here is a high-level overview of the process for a typical S2000 kit:

  1. Prep the car: Ensure the engine is in good mechanical condition. Perform a compression test and valve adjustment. Upgrade the fuel pump and injectors as recommended by the kit manufacturer.
  2. Install the supercharger bracket and drive system: This involves removing the intake manifold, installing a new bracket, routing the belt, and mounting the supercharger unit. Torque all bolts to spec.
  3. Plumb the intake and intercooler system: For intercooled kits, install the radiator or intercooler core, coolant pump (if air-to-water), and piping. Ensure no leaks exist.
  4. Connect fuel and electronics: Fit larger injectors, install a boost-referenced fuel pressure regulator if required, and wire the intercooler pump and any boost controllers.
  5. Install the ECU and tune: Use a Honda FlashPro, AEM standalone, or reflash service. Load a base map from the kit supplier, then log data and iterate to optimize fuel and timing. This step is best done on a dyno by an experienced tuner.
  6. Break-in and verify: After tuning, drive the car gently for at least 50 miles to ensure everything is settled. Monitor fuel trims, knock counts, and oil temperature. Re-check all bolts and belt tension after 100 miles.

Professional installation typically costs $2,000–$3,000 depending on the kit. Custom tuning adds another $500–$1,000. These costs are part of the overall investment but are essential for a reliable, powerful result.

Realistic Expectations: Dyno Charts and Street Performance

To set realistic expectations, consider this: a well-sorted S2000 with an Edelbrock E-Force kit (on 93 octane, with a custom tune) often produces 320-340 whp and 220-240 lb-ft of torque. That's a 50% increase over stock. A Jackson Racing intercooled car at 9-10 psi can make 340-370 whp with a torque curve that climbs steadily to redline. The Comptech falls in between, with about 320-350 whp depending on boost level. Remember, wheel horsepower numbers vary between dynos—Dynojet figures tend to read 10-15% higher than Mustang dynos. Always compare apples to apples.

On the street, a supercharged S2000 transforms from a sweet-handling momentum car into a genuine sports car that can outrun most modern performance vehicles. The immediate torque makes corners more thrilling, and the extra power on straights is addictive. However, the car's chassis and brakes may need upgrades to handle the added speed—consider stiffer springs, better dampers, and a brake pad upgrade.

Common Pitfalls and How to Avoid Them

  • Ignoring fuel system upgrades: Stock injectors and pump are maxed out at around 330 whp. Lean fuel delivery can destroy the engine. Always install a high-flow pump and larger injectors when going beyond base boost.
  • Using a generic tune: A one-size-fits-all calibration may be safe but rarely optimal. Each car has slight differences in compression, airflow, and fuel quality. Invest in a custom tune.
  • Not upgrading the clutch: The stock clutch begins slipping around 320 whp. A stage 1 or 2 clutch (e.g., ACT, Exedy) is mandatory for anything above 300 whp.
  • Neglecting cooling: The S2000's radiator and oil cooler are marginal for boosted applications. Consider a larger radiator, oil cooler, and a high-flow thermostat. Monitor coolant and oil temps during heavy use.
  • Overboosting: Using a smaller pulley without supporting mods (fuel, tuning, intercooling) leads to detonation and engine failure. Plan the build holistically.
