So I went to dyno my Z3 1.9 at my engineering school here in Finland today. Got some nice power figures 152 hp & 185 Nm with only minor modifications that you can check from my garage page! ( 140 hp & 180 Nm as standard)
Also learned a lot about dynoing cars today ^_^
ps. The torque is actually 189 Nm when you calculate out the ETY-standard conditions. Then you actually have the torque the engine produced when tested, even if it doesn’t show in the graph itself.
