In Europe the 2000 Solex was rated at 145 Hp and the 1600 at 90 Hp.
The 67½ 2000 I know of in Sweden is rated at 135 Hp DIN in the car
registration document. It's a factory Solex car sold new in Switzerland.
The 240 Z was rated 140 Hp in Europe vs. the US 151 Hp SAE Gross.
The difference between gross and net hp SAE is usually 10-12% on older
Japanese engines. The difference between SAE net and DIN is usually
1-3% higher for DIN because of a slightly different test procedure but
sometimes the SAE net Hp can be higher than DIN.
Power is measured at 25 degrees C for DIN and 80F(?) for SAE.
