Factory diverter valves are often built to a budget, compromising performance. Upgrading to a performance diverter valve, like the Vr7, offers significant advantages in terms of boost response and overall engine efficiency. Let’s explore why an upgrade is crucial for maximizing your turbocharged engine’s potential.
Why Choose a Performance Diverter Valve Like the VR7?
Turbosmart’s VR7, and other performance diverter valves, leverage advanced engineering and superior materials to surpass the limitations of factory components. This results in improved sealing, faster response times, and enhanced boost control, ultimately leading to a more powerful and responsive driving experience.
Boost-Balance Technology: The Key to VR7 Performance
The VR7 utilizes Boost-Balance Technology, a unique system that relies on pressure differential rather than solely boost pressure to actuate the valve. This allows for the use of a lighter spring, resulting in lightning-fast response times. Furthermore, because both sides of the piston are subjected to equal boost pressure during acceleration, the valve remains firmly closed until intentionally released. This ensures that all available boost is directed to the engine, eliminating lag and maximizing power delivery.
Positive Seal O-Ring: Ensuring Leak-Free Performance
The VR7 incorporates a Viton O-Ring on the valve face, creating a positive seal against the valve body. This crucial feature ensures leak-free operation, maintaining maximum boost pressure under all conditions. This airtight seal contributes significantly to improved boost response and overall engine efficiency. This robust design ensures consistent performance and long-term reliability.
Vacuum and Smoke Testing: Understanding the VR7’s Design
The VR7 can be vacuum tested using a high-flowing mechanical vacuum pump. However, hand-actuated pumps are insufficient as they cannot replicate the airflow experienced in a running engine. Due to its unique design, which prioritizes sealing, speed, and flow, the VR7 is not suitable for smoke testing. Its reliance on a positive seal O-ring, rather than a diaphragm, eliminates the need for this type of testing.
Horsepower Handling: The VR7’s Unwavering Performance
The VR7’s Boost-Balance System ensures that it can handle virtually any level of horsepower and boost. The valve’s sealing capability actually improves with increasing boost pressure. However, extremely modified engines might reach the bypass flow limit of the valve, potentially leading to compressor surge. In such cases, a remote-mounted valve with higher flow capacity might be necessary. However, the VR7 will never prematurely open or vent due to excessive boost or power. The VR7 delivers unwavering performance, regardless of your engine’s output.
