The 3.2L engine pictured here produced 380WHP @ 7980 RPM and produced a peak of 325 Ft/Lb Torque @ 6000 RPM. This was all using mild cams, a stock airbox, and our engine technology of 7 years ago.
The torque of the S54 is a big advantage Vs. the other BMW inline 6 engines. Torque was at a minimum of 310 Ft/LB from 3800 RPM to 7700 RPM without VANOS!
