When it comes to high-performance engines, the debate between LS and HEMI is a hot topic among automotive enthusiasts. Both engine families offer unique advantages and potential for upgrades, especially when aiming for over 700 horsepower. In this article, we will explore the costs associated with upgrading to forced induction components for both LS and HEMI engines, helping you make an informed decision.
Understanding LS and HEMI Engines
The LS engine family, developed by General Motors, is known for its lightweight design and versatility. On the other hand, the HEMI engine, produced by Chrysler, is famous for its power and distinctive combustion chamber design. Both engines have loyal followings and distinct characteristics that appeal to different types of car enthusiasts.
- LS Engines: Lightweight, compact, and great for performance upgrades.
- HEMI Engines: Powerful, with a unique combustion design for high torque.
Cost Factors in Upgrading to 700+ HP
Upgrading either an LS or HEMI engine to achieve 700+ horsepower through forced induction involves several cost factors. Understanding these can help you budget effectively for your performance goals.
1. Engine Base Cost
The initial cost of the engine itself can vary significantly between LS and HEMI options. LS engines are generally more affordable due to their widespread use in various GM vehicles.
2. Forced Induction Components
To reach 700+ horsepower, both engine types will require forced induction components such as superchargers or turbochargers. The cost of these components can vary based on brand, type, and installation complexity.
- Superchargers: Typically range from $3,000 to $7,000.
- Turbochargers: Can range from $2,500 to $6,000.
3. Supporting Modifications
To ensure reliability and performance, supporting modifications are essential. This includes upgrades to fuel systems, exhaust systems, and engine internals. Costs for these modifications can add up quickly.
- Fuel System Upgrades: $1,000 to $3,000.
- Exhaust System Upgrades: $800 to $2,000.
- Engine Internals (pistons, rods): $1,500 to $4,000.
Cost Comparison: LS vs HEMI
When comparing the total costs for upgrading LS and HEMI engines, it is important to consider all the factors discussed. Below is a general overview of the estimated costs associated with each engine type.
LS Engine Cost Breakdown
- Base Engine Cost: $3,000
- Forced Induction: $5,000
- Supporting Mods: $3,000
- Total Estimated Cost: $11,000
HEMI Engine Cost Breakdown
- Base Engine Cost: $4,000
- Forced Induction: $5,500
- Supporting Mods: $4,000
- Total Estimated Cost: $13,500
Performance Considerations
While cost is a significant factor, performance considerations should also play a role in your decision. Both LS and HEMI engines have their strengths and weaknesses when it comes to power delivery, tuning potential, and overall performance.
LS Engine Performance
LS engines are known for their high revving capabilities and lightweight design, making them ideal for applications where weight is a critical factor. They also have a vast aftermarket support, providing numerous options for tuning and performance enhancements.
HEMI Engine Performance
HEMI engines, with their unique combustion chamber design, deliver strong low-end torque, which is beneficial for heavy vehicles and towing applications. They are also capable of producing impressive horsepower figures but may require more extensive modifications to reach the same level as LS engines.
Conclusion
Ultimately, the choice between LS and HEMI engines for upgrading to 700+ horsepower with forced induction comes down to personal preference, budget, and performance goals. Both engines offer unique advantages, and understanding the cost implications will help you make the best decision for your project.
