SV52 Blow-Off Valve by Go Fast Bits.
Why do we use a piston instead of the more common diaphragm design?.
Strength and reliability is the primary factor, something that a diaphragm simply cannot match in a high-boost BOV environment. Diaphragms have their place (we use them in our wastegates), as they offer low friction and good sealing capability. However, a rolling diaphragm is only designed to receive a net pressure on one side, which essentially “inflates” it against the walls of the chamber in which it resides, exactly how it is used in a wastegate.
However, a BOV is exposed to frequent pressure reversals – every time you accelerate and lift off.For a diaphragm, this means it is repeatedly collapsing on itself under boost, then inflating under vacuum. Eventually, this leads to diaphragm failure. A piston on the other hand is immune to this issue, and will continue to operate under the most extreme pressure, temperature, and cyclic conditions.
Features
- Monobloc body design.
- CNC machined from a single aluminium billet.
- The anodized piston bore creates an extremely hard and low-friction surface.
- 300 PSI Boost Pressure.
Benefits
- Standing only 86mm tall (including the weld-on adaptor), the SV52 is 10mm shorter than the nearest competitor, AND flows more!
Please Note: Suits engines with manifold vacuum ranging from 5-22inHg (17-74.5kPa, 2.5-11psi vacuum)
Applications
- Universal.
