The Mopar 383 engine, known for its robust performance, can be significantly enhanced with the right upgrades. One of the most effective ways to boost horsepower is by upgrading to TRW pistons and Comp Cams. This article will guide you through the process of adding 50 horsepower to your Mopar 383.
Understanding the Mopar 383 Engine
The Mopar 383 is a V8 engine that has a storied history in muscle car performance. It was produced from 1963 to 1971 and is revered by enthusiasts for its power and torque. To maximize its potential, understanding its components is crucial.
- Engine Block: The foundation of the 383, designed for strength.
- Crankshaft: A forged steel crankshaft that provides durability.
- Heads: High-performance cylinder heads that can be upgraded.
- Intake Manifold: Essential for airflow management.
Benefits of TRW Pistons
TRW pistons are a popular choice among performance enthusiasts. They are known for their lightweight design and ability to withstand high temperatures and pressures. Here are some benefits of upgrading to TRW pistons:
- Increased Compression Ratio: TRW pistons can raise the compression ratio, leading to more power.
- Lightweight Design: Reduces the overall weight of the rotating assembly.
- Durability: Designed to handle the rigors of high-performance applications.
Choosing Comp Cams
Comp Cams is renowned for producing high-quality camshafts that enhance engine performance. Selecting the right camshaft for your Mopar 383 is crucial for achieving the desired horsepower increase. Key considerations include:
- Duration: The length of time the intake and exhaust valves are open affects engine breathing.
- Lift: Higher lift allows for more air and fuel mixture to enter the combustion chamber.
- Overlap: The timing of valve openings can improve performance at higher RPMs.
Installation Process
Upgrading to TRW pistons and Comp Cams requires careful installation. Here’s a step-by-step guide:
- Remove the Engine: Start by removing the engine from the vehicle for easier access.
- Disassemble the Engine: Take apart the engine components, including the cylinder heads and intake manifold.
- Replace Pistons: Remove the old pistons and replace them with TRW pistons, ensuring proper clearance.
- Install Camshaft: Replace the stock camshaft with the chosen Comp Cams camshaft, following manufacturer specifications.
- Reassemble the Engine: Put the engine back together, ensuring all components are secured.
- Reinstall the Engine: Place the engine back into the vehicle and connect all necessary components.
Tuning for Maximum Performance
After installation, tuning is essential to maximize performance gains. Consider the following:
- ECU Tuning: Adjust the engine control unit settings to optimize fuel and ignition timing.
- Dyno Testing: Use a dynamometer to evaluate horsepower and torque output.
- Fuel Quality: Ensure the use of high-octane fuel for optimal performance.
Expected Results
With the right upgrades, your Mopar 383 can see a significant increase in horsepower. Many enthusiasts report gains of up to 50 horsepower with the combination of TRW pistons and Comp Cams. This enhancement not only improves acceleration but also overall driving experience.
Conclusion
Upgrading to TRW pistons and Comp Cams is an effective way to boost the performance of your Mopar 383. With careful selection and installation, you can achieve substantial horsepower gains, making your vehicle a true powerhouse on the road.
