- Fuel Pump: $200 – $600
Exhaust System Enhancements
A high-performance exhaust system can improve airflow and enhance engine efficiency. Upgrading headers and catalytic converters can contribute to horsepower gains.
- Headers: $400 – $1,200
- Cat-Back Exhaust System: $500 – $1,500
Tuning and Calibration
After making hardware modifications, tuning is crucial to ensure optimal performance. A professional tune adjusts the engine’s computer settings to maximize power and efficiency.
- Dyno Tuning: $300 – $1,000
Total Cost Estimate
Now that we’ve broken down the components, let’s estimate the total cost for a 150 HP increase on a Chevy Chevelle.
- Engine Modifications: $1,800 – $5,200
- Forced Induction: $2,500 – $7,000
- Fuel System Upgrades: $500 – $1,400
- Exhaust System Enhancements: $900 – $2,700
- Tuning: $300 – $1,000
Considering all these factors, the total estimated cost for a 150 HP increase can range from approximately $6,100 to $17,300, depending on the choices made and the quality of parts used.
Conclusion
Increasing the horsepower of a Chevy Chevelle by 150 HP can be an exciting project for any car enthusiast. While the costs can vary widely based on the modifications chosen, understanding the breakdown of expenses can help you plan your build effectively.
