It features an arrangement of Viton o-ring seals unique to GFB.\u003c\/p\u003e\u003cp\u003eDESIGN\u003c\/p\u003e\u003cp\u003eWhy do we use a piston instead of the more common diaphragm design?\u003c\/p\u003e\u003cp\u003eStrength 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.\u003cbr\u003e\u003cbr\u003eHowever, a BOV is exposed to frequent pressure reversals \"\" every time you accelerate and lift off.\u003cbr\u003eFor 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.\u003cbr\u003e\u003cbr\u003eThe unique mounting method of the SV52 is one of the ways weve been able to save unnecessary bulk.\u003cbr\u003eBy eliminating the v-band style mount, the piston and its venting ports can sit much lower, which reduces the overall height to a number others cant match.\u003c\/p\u003e                \u003cp\u003e \u003c\/p\u003e        \u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFeel free to contact us at info@mlperformanceusa.com should you wish to double check!\u003c\/p\u003e        \u003cp\u003e \u003c\/p\u003e        \u003ch4\u003eCompatibility Check\u003c\/h4\u003e\u003cp\u003eTo ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch.
