Starting values are examples. Enter your measurements; results update as you type.

Method & assumptions

Ideal proportional absolute-pressure estimate. Assumes unchanged charge temperature, volumetric efficiency and losses. Actual required boost depends on compressor heat, intercooling, exhaust backpressure and engine efficiency.
