Scott Shafiroff Racing Engines Oxygen Sensors
|
Eight oxygen sensors are plumbed into the dyno headers and record for each dyno pull. These sensors record air/fuel ratio and Marshall can tune the carburetor to properly distribute fuel equally to each cylinder. That way the most power can be made when all eight cylinders are pumping the same. Most EFI systems use one 02 sensor installed in one collector to tune the entire engine. The eight-sensors method is far more accurate, but is also pricier. SSRE is serious about delivering the engine in perfect running order. View Related Article
