BMW High-Performance Exhaust VANOS Modification
When building high horsepower BMW engines, the exhaust VANOS system can become a limiting factor, particularly in applications with increased fuel system demands.
Because the high-pressure fuel pumps are driven by the exhaust camshaft, increased fuel demand places additional load on the cams
