Thought some of you might find this interesting....

It's the torque-power curves obtained by a spanish magazine back in 1988 when testing the bmw 325i manual (m20B25 engine)



Hope you like it

EDIT: sorry, I forgot to translate it

Curva de potencia: power curve
Curva de par: torque curve
They also compare the official and actual figures. BMW published 171 CV DIN at 5800 rpm and they got 172.67. For torque, the BMW figure was 22.5 kg-m DIN (162.7 pound-feet) at 4000 rpm, they got 22.7 (164.4) at the same rpm. They said the engine had decent pull at lower revs, but really felt alive above 4000 rpm and it spinned easily to the 6500 rpm limiter (almost so easily they felt dissapointed to hit the limiter and wondered how much power it would develop at higher rpm)
