Understanding the Honda S2000 AP2 Engine

The S2000 AP2 features a 2.2-liter F22C1 inline-four engine, which produces 240 horsepower and 162 lb-ft of torque. It is renowned for its VTEC system, which enhances performance at high RPMs. To reach 280 horsepower, modifications are often considered, but understanding the engine’s capabilities is crucial.

Owner Experiences: Achieving 280 HP

Several S2000 owners have shared their experiences in attempting to reach the coveted 280 horsepower mark. Here are some insights from the community:

  • Engine Tune: Many owners report that a proper ECU tune can significantly increase power. Some have achieved gains of up to 30 horsepower with a quality tune.
  • Intake and Exhaust Mods: Upgrading to a high-performance intake and exhaust system can help optimize airflow, contributing to increased horsepower.
  • High-Performance Headers: Installing aftermarket headers has been a common modification that owners claim can help push power closer to 280 HP.
  • Fuel System Upgrades: Some owners suggest upgrading fuel injectors and the fuel pump to support higher power levels.
  • Dyno Testing: Many enthusiasts recommend using a dyno to measure horsepower accurately after modifications.

Real-Life Examples

Here are a few specific examples from owners who have successfully reached or approached 280 horsepower:

  • Owner A: Achieved 275 HP with a custom tune, a cold air intake, and a full exhaust system. They reported a noticeable increase in throttle response and power delivery.
  • Owner B: Reached 282 HP by adding high-performance headers and upgrading the fuel system. They emphasized the importance of a proper tune to maximize gains.
  • Owner C: Managed to hit 278 HP using a combination of intake and exhaust modifications along with a dyno tune, highlighting the effectiveness of airflow improvements.

Factors Influencing Power Output

Several factors can influence the ability to achieve 280 horsepower on a stock S2000 AP2:
