Instead, you can connect your crankcase to both the intake manifold (for a strong vacuum source under low engine load) and the turbocharger intlet (for a venturi vacuum source under boost) at the same time. The dual check valve will ensure the source with the strongest vacuum will actively evacuate crankcase gases, while holding up to 300 psi of boost pressure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe clean air inlet (or vent line) to the crankcase can be completely sealed off to maximize crankcase vacuum, minimizing crankcase pressure. Reducing crankcase pressure will result in less windage and drag on the rotating assembly, increasing horsepower to the wheels. If allowing some clean air to vent the crankcase is still desired, a non-venturi vent line can be connected to the intake piping with a restrictor valve (see Improved Racing part # \u003ca href=\"https:\/\/www.improvedracing.com\/catalogsearch\/result\/?q=FO-06R\"\u003eFO-06R\u003c\/a\u003e).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0629\/9556\/2683\/files\/DCV-DUAL-OPEN.jpg?v=1769436444\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0629\/9556\/2683\/files\/DCF-SINGLE-OPEN.jpg?v=1769436470\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eUltra-Low Flow Restriction\u003c\/h2\u003e\n\u003cp\u003eMost check valve designs - including poppet check valves, ball check valves, diaphragm check valves, piston check valves, and others - are restrictive, resulting in a pressure drop across the valve even when fully open.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eImproved Racing's check valves use a flapper design, originally developed for military jet engine turbines, that swings completely out of the fluid's flow path, adding virtually no flow restriction.
