It appears as though the fiesta st is equipped with a Borg Warner k39 turbo. Has anyone been able to find a compressor map for it yet?

Ive looked for that info aswell with no luck. Its a relatively small turbo that is also used on vw/audi tdi's.

It would be nice to find a gas engined equivalent to know what it's efficiency max's out at.
