Eventuri Chevrolet Corvette C8 ZR1 Hard-Top Convertible Black Carbon Intake System
$3,595.00
The Eventuri Chevrolet Corvette C8 ZR1 Hard-Top Convertible Black Carbon Intake System represents a comprehensive re-engineering of the LT7 intake architecture, delivering performance gains rarely achieved from an intake system alone. Developed from the ground up using advanced CFD analysis, dyno validation, and iterative prototyping, this system addresses the inherent airflow limitations of the OEM design while significantly increasing volumetric efficiency and turbocharger response.
Building on Eventuri’s proven C8 Stingray and Z06 systems, the ZR1 intake introduces a significantly larger intake architecture unconstrained by the factory trunk panel. By eliminating this restriction, Eventuri was able to design a high-volume, organically shaped intake system paired with enlarged turbo inlet tubes, each offering approximately 30% greater internal volume compared to OEM. This increase in cross-sectional area reduces pressure drop, allowing the turbochargers to achieve target boost levels more efficiently and earlier in the RPM range.
The OEM airbox, derived from the LT6 Z06 platform, becomes increasingly restrictive when paired with the higher-output LT7 engine. Eventuri’s solution replaces this with a fully carbon fiber intake system utilizing their patented Venturi housing technology. This design optimizes airflow velocity while maintaining laminar flow conditions through the intake tract, reducing turbulence and improving charge consistency to each turbocharger.
Engineering and Development
CFD analysis was conducted extensively to refine internal geometry and airflow behavior. The intake transitions turbulent upstream air into a smooth, linear flow path through the MAF sections and into the turbochargers. The result is increased velocity without sacrificing flow stability, ensuring consistent and repeatable performance gains across the entire RPM range.
Dyno testing was carried out in a controlled environment using a stock C8 ZR1. Baseline runs were conducted at stabilized temperatures, followed by installation of the intake system and repeated runs under identical conditions. Even with higher ambient temperatures during post-installation testing, the intake delivered substantial gains, particularly in the mid-range around 5300 RPM.
System Components
- Carbon Fiber Double Venturi Filter Housing
- Bespoke High-Flow Dry Cone Filters (ISO tested)
- Carbon Fiber Inlet Ducts with Neoprene Sealing
- Carbon Fiber Turbo Tubes (30% increased internal volume)

- Laser-Cut Stainless Steel and Aluminum Brackets
- Custom Inlet Flanges for sealed cold air feed integration
Patented Venturi Housing
The core of the system is Eventuri’s patented double Venturi filter housing, which merges dual airflow paths into a centralized high-volume chamber. As airflow transitions through the housing, the gradually reducing cross-sectional area accelerates velocity while maintaining laminar flow characteristics. This principle, similar to a velocity stack, ensures efficient air delivery to each turbocharger while minimizing drag and turbulence.
Thermal Management and Airflow Control
Carbon fiber inlet ducts channel ambient air directly from the side vents into the intake system. These ducts are sealed to the filter housing using a neoprene gasket and multi-point mounting system to prevent heat soak from the engine bay. Combined with sealed inlet flanges and flexible hose connections, the system maintains a consistent supply of cold air under all driving conditions.
