As fuel demand increases, the additional load required to drive the pumps places significant resistance on the exhaust cam and VANOS system. At extreme power levels, high RPM, and heavy load, the VANOS system can struggle to maintain the commanded exhaust cam position.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eRather than modifying the factory VANOS system to increase its operating range, our 5150 S58 Exhaust VANOS Full Elimination completely removes exhaust VANOS adjustment and converts the exhaust camshaft to a fixed mechanical timing position.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThis solution is designed specifically for dedicated race engines where consistent and repeatable exhaust cam timing is more important than variable camshaft operation.\u003c\/p\u003e\n\u003ch3\u003eWhy Eliminate Exhaust VANOS?\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003eAt extreme power levels, exhaust cam movement can become inconsistent due to the increased load placed on the system.
