Building a 600+ Hp C5 Corvette Z06: Camshaft, Heads, and Forced Induction Recommendations

by

The C5 Corvette Z06 is a legendary vehicle known for its performance and handling. With the right modifications, it can easily exceed 600 horsepower, making it a thrilling ride for enthusiasts. In this article, we will explore the best camshaft, heads, and forced induction options to achieve this power goal.

Understanding the C5 Corvette Z06

The C5 Z06, produced from 2001 to 2004, features a lightweight aluminum frame and a powerful LS6 engine. It is equipped with a 5.7-liter V8 that initially produces around 405 hp. However, with the right upgrades, this engine can be transformed into a powerhouse.

Choosing the Right Camshaft

A performance camshaft is crucial for maximizing horsepower and torque. When selecting a camshaft for your C5 Z06, consider the following:

  • Duration: Look for a cam with a duration between 220-240 degrees for optimal performance.
  • Lift: A lift of .600 inches or more will help increase airflow.
  • LSA (Lobe Separation Angle): A tighter LSA (around 112 degrees) can improve throttle response.
  • Texas Speed Stage 2 Cam: Known for excellent power across the RPM range.
  • Brian Tooley Racing (BTR) Stage 3 Cam: Offers a great balance of power and drivability.
  • Comp Cams XFI RPM Cam: Designed for high RPM performance with a strong mid-range.

Upgrading Cylinder Heads

Upgrading the cylinder heads is another critical step in achieving 600+ hp. High-flow heads can significantly improve airflow, which is essential for high horsepower builds.

  • Ported Stock Heads: A cost-effective option that can yield significant gains.
  • Aftermarket Heads: Consider brands like AFR or Trick Flow for high-performance options.
  • Flow Bench Testing: Ensure your heads are flow-tested to verify performance gains.
  • AFR 205cc Heads: Excellent airflow and power potential.
  • Trick Flow 235cc Heads: Designed for high RPM applications with great torque.
  • Texas Speed 225cc Heads: Great for both street and track use.

Forced Induction Options

Adding forced induction is one of the most effective ways to achieve over 600 hp. There are several options to consider:

  • Supercharger: A centrifugal supercharger can provide a linear power band and is easier to install.
  • Turbocharger: Offers the potential for massive power but requires more complex installation and tuning.
  • Roots Blower: Provides immediate boost and can enhance low-end torque.
  • Whipple Supercharger: Known for its reliability and power gains.
  • Procharger P-1SC: A popular choice for its efficiency and performance.
  • Turbonetics Turbo Kit: Offers a high horsepower potential with proper tuning.

Tuning and Supporting Mods

After upgrading your camshaft, heads, and adding forced induction, proper tuning is essential to maximize performance and ensure reliability. Supporting modifications may include:

  • High-Performance Fuel System: Upgrade fuel injectors and pump to support increased horsepower.
  • Headers: Long-tube headers can improve exhaust flow and overall performance.
  • Cold Air Intake: Enhances airflow to the engine for better combustion.

Conclusion

Building a 600+ hp C5 Corvette Z06 is an exciting project that requires careful planning and execution. By selecting the right camshaft, heads, and forced induction system, along with proper tuning and supporting modifications, you can unlock the full potential of your Z06 and enjoy an exhilarating driving experience.
