Our valves have been a highly sought-after product, but due to the intensive assembly process, it has been hard to keep them on the shelves, which in turn causes frustration among our customers. To address this issue, our team has worked diligently to redesign the BPV to make the assembly process more efficient, while also \u003cstrong\u003eimproving its manufacturability, performance, and overall reliability.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat's New for Version 2?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRedesigned the internal piston to eliminate the potential failure points we saw in our V1 design.\u003c\/li\u003e\n\u003cli\u003eAdjusted tension of the internal spring to better suit the operating environments we've seen after further testing and development.\u003c\/li\u003e\n\u003cli\u003eUpdated the design of the main body for a better CNC milling finish.\u003c\/li\u003e\n\u003cli\u003eExchanged the internal brass piston from V1 for a lighter weight hard aluminum piston, resulting in better valve response.\u003c\/li\u003e\n\u003cli\u003eRemoved the inspection port which was primarily used for quality control, but it is not required with the new design.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn testing of stock bypass valves, we saw repeated internal leakage at boost levels as low as 8psi in the FA20 and 19psi in the EJ variant. As always the case with GrimmSpeed Products, we focus on \u003cstrong\u003eform AND function\u003c\/strong\u003e, and these units are no exception. We aimed to create an \u003cstrong\u003eextremely durable bypass valve\u003c\/strong\u003e that could hold double the pressure of the stock unit, while still being a stylish part that compliments the other GrimmSpeed Parts under your hood.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Design\u003c\/h3\u003e\u003cp\u003eWe started the ground-up design with the valve body and base for each popular fitment. Both are CNC-machined out of billet 6061 aluminum alloy for its strength and light-weight. They are then anodized in either a black or red finish to give them a brilliant appearance, provide corrosion resistance and match other GrimmSpeed offerings. Compared to the stock cast unit on the EJ STI and plastic construction on both the 08-14 and 15-21 WRX platforms, \u003cstrong\u003eGrimmSpeed Bypass Valves not only stand out, but are guaranteed to stand the test of time.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eVersion 2 replaces the original brass piston with a lighter hard aluminum piston for improved valve response. Our piston seats onto an internal O-ring to create a perfect seal, \u003cstrong\u003eeliminating boost leaks common in OEM and cheap aftermarket BPVs\u003c\/strong\u003e. In order to make sure this could keep up with high power levels, we chose to use a massive 38mm diameter piston\/sealing ring for the ability to dump pressure quickly. This is especially important on high boost applications to keep the turbo from sustaining damage and the BPV maintaining leak-free operation. A precisely-tuned steel spring alleviates the need for any tuning or adjusting of the valve, \u003cstrong\u003ewith no engine tuning required to run the unit\u003c\/strong\u003e. Buna-N O-rings were the next logical choice due to their resistance to degradation from fuel and oil exposure. In addition, all of our O-ring grooves utilize a single dovetail design for superior retention. This guarantees the O-ring will not fall out and has the perfect crush for sealing the body together. To top things off, we employ a swivel fitting on the valve to make for easy installation and accommodate best-routing on custom setups. A GrimmSpeed signature branding badge graces the top of each unit so that everyone will know you chose the best valve in the biz.\u003c\/p\u003e\n\u003ch3\u003eQuick Specs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCNC-Machined 6061 Aluminum\u003c\/li\u003e\n\u003cli\u003eCorrosion resistant anodized finish\u003c\/li\u003e\n\u003cli\u003eOversized 38mm anodized aluminum piston for superior flow\u003c\/li\u003e\n\u003cli\u003eSwivel air fitting to aid in install and for accommodating custom setups\u003c\/li\u003e\n\u003cli\u003eNo tuning or adjustment required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSubaru WRX 2015-2021\u003c\/li\u003e\n\u003cli\u003eSubaru Forester XT 2014-2018\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.youtube.com\/watch?v=P-zjTcB8ALo\"\u003eGrimmSpeed Bypass Valve Install Video\u003c\/a\u003e\u003c\/p\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":67600349397299,"sku":null,"price":284.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0256\/5855\/6497\/files\/grimmspeed-v2-bypass-valve-red.jpg?v=1790877188","url":"https:\/\/www.circuitspecr.com\/products\/grimmspeed-version-2-bypass-valve-red-subaru-wrx-2015-2021-subaru-forester-xt-2014-2018","provider":"Circuit Spec R","version":"1.0","type":"link"}
