125-85 Holley 8.5 Power Valve
The 125-85 Holley 8.5 Power Valve is an essential component designed for performance enthusiasts looking to optimize their carburetor functions, especially in supercharged setups. This power valve is engineered with unique features that elevate your engine's performance, ensuring that your vehicle runs smoothly under various conditions.
Key Features:
- External Referencing Capability: The power valve references the intake manifold vacuum below the supercharger, allowing it to function optimally based on the actual engine load.
- Enhanced Fuel Delivery: Provides additional enrichment to the main metering system during load and low vacuum conditions, ensuring your engine receives the fuel it needs when it matters most.
- Prevents Boost Pressure Misreading: Without the external reference, typical power valves read supercharger boost pressure, which is not relevant to engine load. The 125-85 eliminates this issue.

- Includes Gasket: Comes complete with a gasket for easy installation and enhanced performance.
