    pardon my ignorance, what motor is in the Z4M?
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    That is right, a beautiful NA masterpiece of a motor with a flat curve.

    We need to translate that torque curve (proportional to the whp)
    over to the turbo S54 builds.

    Ummm, that dyno doesn't look right for a s54. How is it making more torque than horsepower?

    The torque may be in a different measurement than pound-feet on the graph. Yes, I know what it says on the right hand side.

    Edit: Actually, I am pretty sure that is Newton Meters used for the peak numbers.

    Those are solid numbers for an N/A S54. Usually if I'm not mistaken it takes headers to get to get to 300rwhp. I'd like to see a baseline

    I'm sure that is a euro car which already comes with nice headers that don't have the cats built into them...

    That should be correct, probably only the US that got that damn cat built into the header.

    I'm still interested in what measurement is being used for the "torque"...

    good point, I only took a quick glance and didn't realize this was a vehicle from overseas.
