The journey to building a reliable 700 horsepower HEMI engine begins with a solid foundation. A strong bottom end is crucial for handling the power and stress associated with high-performance applications. In this article, we will explore how to strengthen the bottom end using quality components from Manley and Mahle.
Understanding the HEMI Engine
The HEMI engine, known for its distinctive hemispherical combustion chamber, provides excellent performance and efficiency. However, to achieve 700 hp, modifications to the bottom end are essential to ensure durability and reliability.
Key Components for Strengthening the Bottom End
- Connecting Rods
- Pistons
- Crankshaft
- Engine Bearings
- Oil Pump
Connecting Rods
Upgrading to high-performance connecting rods is essential for handling the increased power. Manley offers a range of connecting rods designed to withstand the rigors of high horsepower applications.
Pistons
Mahle pistons are known for their strength and lightweight design. Choosing the right pistons can help increase compression and improve overall engine performance while ensuring longevity under high-stress conditions.
Crankshaft
The crankshaft is the heart of the engine, and upgrading to a forged crankshaft can significantly enhance strength and reliability. Look for options that are specifically designed for high-performance applications.
Engine Bearings
High-quality engine bearings are critical for reducing friction and ensuring proper oil flow. Manley offers a selection of bearings that are tailored for high-performance engines, providing the durability needed for a 700 hp HEMI.
Oil Pump
A high-performance oil pump is essential for maintaining proper lubrication at high RPMs. Upgrading to a performance oil pump can help ensure that your engine receives the oil it needs to perform reliably.
Assembly Tips for a Reliable Build
Proper assembly techniques are just as important as the components themselves. Here are some tips to ensure a successful build:
- Follow torque specifications carefully.
- Use assembly lube on all moving parts.
- Ensure proper clearances for bearings and pistons.
- Double-check all components before final assembly.
Testing and Tuning Your HEMI
Once your engine is assembled, it’s crucial to test and tune it properly. A dynamometer can help you measure horsepower and torque, allowing you to make necessary adjustments for optimal performance.
Break-In Period
During the break-in period, it’s essential to monitor oil pressure and temperatures closely. Follow the manufacturer’s recommendations for break-in procedures to ensure the longevity of your engine.
Conclusion
Building a reliable 700 hp HEMI requires careful selection of components and attention to detail during assembly. By utilizing high-quality parts from Manley and Mahle, you can create a strong bottom end capable of handling the power demands of high-performance driving.
