Power figures are SAE net unless noted SAE gross, DIN, or JIS. Early (1960 and before) German horsepower figures are almost certainly gross even if not marked as such. American horsepower appears to have gone to net about 1970. Multiplying JIS by .80 or .85 gives SAE net.
Engine capacities are quoted as single chamber capacity. Various bodies de-rate the RCE by applying coefficients of 1.7, 1.8, 2.0 or even 3.0 to boost the apparent size.
