Din HP is indeed ( slightly) larger than SAE HP....therefore requiring "fewer" of these DIN HP for the same output motor power.

Wil, All kidding aside, 1 HP= 1 HP. DIN and SAE just use 2 (slightly) different measurements on the motor, ie. one measures w/ all accesories hooked up, one doesn't, or something like that. I forget.

The DIN figure will be higher than the SAE figure for the same powerplant, as evidenced by Porsches #s for 911s. The 2.4 911S was rated 181 SAE net HP @ 6500 rpm by Porsche, and I believe 190 DIN HP. (Source: The Porsche Family Tree , 1983. Official factory literature). :cool:

well according to Porsche.com

here the 911SC from 1980 is went from 180 to 188, and then in 1981-1983 it was 204 hp...

Euro spec, not US spec.

Those are all true figures.........., for the ROW (Euro) car. The problem is when people mix and match Euro and U.S. specs, it is no longer an "apples to apples" conversation. FWIW, I greatly prefer all of the 1980s 911s in ROW models.

This didn't scan very well, but here are official U.S. specs from Porsche factory literature showing all of the SCs @ 172 SAE net HP, 1978-1983:
