Dyno Results: How a $2,500 Cam Swap Can Boost Your Trans Am’s Horsepower by 50-70 Hp

by

The quest for horsepower is a never-ending journey for car enthusiasts, especially for those who own a classic muscle car like the Trans Am. One of the most effective modifications to increase horsepower is a camshaft swap. In this article, we will explore how a $2,500 cam swap can yield an impressive boost of 50-70 horsepower for your Trans Am.

Understanding Camshafts

A camshaft is a crucial component in an internal combustion engine. It controls the timing and duration of the opening and closing of the engine’s valves. By modifying the camshaft, you can significantly alter the engine’s performance characteristics.

Why Upgrade Your Camshaft?

Upgrading your camshaft can enhance your engine’s ability to breathe, allowing it to produce more power. Here are some reasons why you should consider a cam swap:

  • Increased Horsepower: A new camshaft can provide a substantial increase in horsepower.
  • Improved Torque: Along with horsepower, you can also experience a boost in torque.
  • Better Throttle Response: A performance cam can enhance throttle response for a more engaging driving experience.
  • Enhanced Sound: A more aggressive camshaft can change the exhaust note, giving your Trans Am a more muscular sound.

Choosing the Right Camshaft

Not all camshafts are created equal. When selecting a camshaft for your Trans Am, consider the following factors:

  • Lift: This refers to how far the valves open. Higher lift generally means more airflow.
  • Duration: The length of time the valves are open during the engine cycle. Longer duration can lead to more power at higher RPMs.
  • Overlap: This is the period when both the intake and exhaust valves are open simultaneously. More overlap can improve performance at higher RPMs.
  • Driving Style: Consider how you use your Trans Am. A camshaft optimized for high RPM performance may not be ideal for daily driving.

The Cost of a Cam Swap

The cost of a cam swap can vary significantly based on the components used and labor costs. Here’s a breakdown of what to expect:

  • Camshaft Cost: A quality performance camshaft typically ranges from $500 to $1,500.
  • Additional Components: You may need to purchase lifters, pushrods, and valve springs, which can add another $500 to $1,000.
  • Labor Costs: If you’re not doing the swap yourself, labor can range from $500 to $1,000 depending on the shop rates.

Dyno Testing: Measuring the Gains

After completing a cam swap, it’s essential to measure the performance gains through dyno testing. This process involves running your vehicle on a dynamometer, which measures horsepower and torque output. Here’s what you can expect:

  • Baseline Run: Before the cam swap, perform a baseline dyno run to establish your starting horsepower and torque numbers.
  • Post-Swap Run: After the cam swap, run the dyno again to see the improvements in horsepower and torque.
  • Expected Gains: Many Trans Am owners report gains of 50-70 horsepower after a quality cam swap.

Real-World Dyno Results

To illustrate the potential gains from a cam swap, let’s look at some real-world dyno results from Trans Am owners:

  • Owner A: Swapped to a performance cam and gained 60 horsepower, bringing total output to 400 horsepower.
  • Owner B: Experienced a 50 horsepower increase, achieving a total of 370 horsepower.
  • Owner C: With a more aggressive cam, saw a peak gain of 70 horsepower, reaching 420 horsepower.

Considerations and Recommendations

While a cam swap can provide significant performance benefits, there are a few considerations to keep in mind:

  • Fuel Quality: Upgrading your cam may require higher octane fuel to prevent knocking.
  • ECU Tuning: A tune may be necessary to optimize engine performance after the swap.
  • Driveability: Consider how the new cam will affect the car’s overall driveability, especially at low RPMs.

Conclusion

A $2,500 cam swap can be a game-changer for your Trans Am, providing a significant boost in horsepower and enhancing your driving experience. By understanding the components involved, the costs, and the potential gains, you can make an informed decision about this modification. Whether you’re a weekend warrior or a daily driver, a camshaft upgrade could be the performance enhancement your Trans Am needs.
