How much HP does a cam add to a 5.7 Hemi Challenger?
Adding a performance camshaft to a 5.7L Hemi engine in a Dodge Challenger can provide a significant boost in horsepower (HP). Depending on the specific camshaft and other modifications, a cam swap can add anywhere from 20 to 50 additional HP to the Challenger's output.
Understanding the Impact of a Camshaft Upgrade
The camshaft is a critical component in an internal combustion engine, as it controls the opening and closing of the intake and exhaust valves. By upgrading to a more aggressive camshaft profile, you can increase the duration and lift of the valves, allowing more air and fuel to flow through the engine. This, in turn, can result in a noticeable increase in horsepower and torque.
The exact HP gain from a cam swap on a 5.7L Hemi Challenger will depend on several factors, including:
- Camshaft Specifications: The specific lift, duration, and lobe separation angle of the new camshaft will determine the power increase.
- Engine Modifications: Other upgrades, such as a cold air intake, headers, or a tune, can further amplify the benefits of the camshaft swap.
- Driving Conditions: The power gains may be more noticeable at higher RPMs, where the camshaft's influence is more pronounced.
It's important to note that a camshaft upgrade is often part of a larger engine modification plan, as the increased airflow and power may require additional upgrades to the fuel system, ignition, and other components to ensure optimal performance and reliability.
Typical Horsepower Gains from a Cam Swap
Based on the available information, a typical camshaft upgrade for a 5.7L Hemi Challenger can provide the following horsepower gains:
- Mild Cam: 20-30 HP increase,,
- Moderate Cam: 30-40 HP increase,,
- Aggressive Cam: 40-50 HP increase,,
It's important to consult with a professional mechanic or engine builder to determine the best camshaft option for your specific Challenger and driving needs, as well as to ensure the installation is performed correctly and safely.
