I only get 12psi to 15 psi of manifold pressure now. The boost ran about 26.6 going up the mountains north of Redding. Normal coolant temp is 185-190 but will rise to 205-210 when running WFO. 2. The boost ran about 26.6 going up the mountains north of Redding. The C12 takes full advantage of the electronically controlled unit injection fuel system, resulting in an environmentally friendly engine with outstanding performance and fuel economy. To add another data point to your original question about boost - our C12 typically generates 22 psi boost under full load-full speed conditions. It doesn't pull in 10th much at all. Are these 700HP C-12? (28) Boost pressure sensor (29) Boost pressure The injection pump, the fuel lines, and the nozzles that are used in the traditional Caterpillar diesel engines have been replaced with an electronically controlled, mechanically actuated electronic unit injector in For accurate air intake system pressure readings, the MAP sensor will measure the amount of pressure inside the intake manifold. No obvious cracks around turbo. I have checked for leaks in intercooler and pipes. Two things to start with: 1. Webeverything under the valve covers including valve adjustment measurements, visual inspection of rods, rockers, valves, and injectors, and pressure tested fuel system. If a wastegate is fitted with springs rated to 7PSI, it will open when it receives 7PSI of pressure to the actuator. Running about 60 mph on cruise control it would shift down one gear and hold about 55 mph. When the engine is stopped, the absence of boost pressure allows the plunger to rise to the open position, which allows condensation from the aftercooler to drain out.
