There is no factory supercharged CR-Z; the stock CR-Z uses Honda’s hybrid system to deliver about 122 horsepower in total. If you hear about a “supercharged CR-Z,” it refers to aftermarket modifications, and horsepower will vary widely based on the kit and tuning choices.
Factory CR-Z horsepower and the absence of a factory supercharger
The Honda CR-Z blends a 1.5-liter inline-four engine with Honda’s Integrated Motor Assist (IMA) hybrid system. The combined output is rated at about 122 horsepower, with the electric motor providing additional assist. Honda did not offer a factory-supercharged or turbocharged CR-Z option during its production years, so any boosted performance comes from third-party modifications.
Aftermarket supercharging: what to expect
Because there was no factory supercharger, any boosted CR-Z is an aftermarket installation. The horsepower outcome depends on the boost level, accompanying fuel system upgrades, tuning, and how the hybrid powertrain is managed. Below are representative ranges reported by installers and dyno tests.
- Basic boost (approximately 6–8 psi): roughly 180–210 hp at the crank
- Moderate boost (approximately 8–12 psi): roughly 210–240 hp at the crank
- High-boost setups (above 12 psi) with supporting upgrades: roughly 240–270+ hp at the crank
Actual results vary with the chosen kit, the quality of the installation, fueling and ignition tuning, reliability considerations, and how the hybrid system is integrated with the forced-induction setup. Some builds may require significant modifications to the fuel system, exhaust, cooling, and engine management to maintain reliability and performance.
Notes on hybrid integration and reliability
Boosting a hybrid-equipped car like the CR-Z involves more than just adding a supercharger. Many tuners factor in the IMA system’s role in power delivery, and some drivers opt to modify or retune the IMA to avoid conflicts between the engine and electric motor. Prospective buyers should consider warranty implications, cooling needs, and long-term reliability when choosing a boost path.
Summary
The CR-Z did not come with a factory supercharger, with its performance capped near 122 hp combined. Any supercharged CR-Z is an aftermarket project, and horsepower can range from about 180 hp to 270+ hp at the crank depending on the kit and tuning. Prospective owners should weigh the potential gains against reliability, fuel economy shifts, and warranty considerations.
