The Chevrolet Cobalt SS is known for its performance and tuning potential, particularly when it comes to forced induction. Among the popular options for supercharging the Cobalt SS are the Whipple and Edelbrock superchargers. This article will compare these two systems to determine which one offers greater power gains.
Overview of Supercharging
Supercharging is a method of forced induction that compresses the air entering the engine, allowing for more fuel to be burned and thus increasing power output. There are various supercharger types, but the two most common types used in aftermarket applications are roots-type and twin-screw superchargers.
Whipple Supercharger
The Whipple supercharger is a twin-screw type that is known for its efficiency and ability to produce significant power gains. Here are some key features:
- Power Output: Whipple superchargers can significantly increase horsepower, often adding 100-200+ hp to the Cobalt SS.
- Efficiency: Twin-screw designs are more efficient at compressing air, leading to less heat generation and better overall performance.
- Installation: Whipple systems are designed for relatively straightforward installation, with detailed instructions and support available.
Performance Characteristics
One of the standout features of the Whipple supercharger is its ability to maintain boost pressure across a wide RPM range. This results in strong performance from low to high RPMs, making the Cobalt SS feel more responsive and powerful during acceleration.
Edelbrock Supercharger
The Edelbrock supercharger is also a popular choice for Cobalt SS enthusiasts. It features a roots-type design, which has its own set of advantages:
- Power Output: Edelbrock superchargers typically add around 50-100 hp, which is less than Whipple but still significant.
- Torque Delivery: Roots-type superchargers provide instant torque, which enhances drivability and responsiveness at lower RPMs.
- Installation: Edelbrock kits are known for their ease of installation, often coming with all necessary components.
Performance Characteristics
The Edelbrock supercharger excels in providing immediate power delivery, making the car feel lively during everyday driving. However, it may not sustain power as effectively at higher RPMs compared to the Whipple.
Comparative Analysis
When comparing the Whipple and Edelbrock superchargers, several factors should be considered:
- Power Gains: Whipple generally offers more horsepower than Edelbrock, making it the better choice for those seeking maximum performance.
- Torque Characteristics: Edelbrock provides better low-end torque, which can enhance everyday drivability.
- Heat Management: Whipple’s design is more efficient, resulting in lower intake temperatures and consistent performance.
- Cost: Pricing for both kits can vary, but Whipple systems tend to be more expensive due to their advanced technology.
Conclusion
Ultimately, the choice between Whipple and Edelbrock superchargers for the Cobalt SS depends on the driver’s performance goals. If maximum horsepower and efficiency are the priorities, the Whipple supercharger is likely the better option. However, if immediate torque and drivability are more important, the Edelbrock supercharger remains a strong contender.
Both superchargers can transform the Cobalt SS into a more powerful machine, and the decision should be based on individual preferences and intended use.
