At least 1000nm, but very difficult to reach that.
Max power issue comes from engine working principle.
With same true fuel injection rate 3500 => 4000rpm, you get at least 50-60 "free" hp.
In my car, good burning principle collapses just before 3500rpm, and there is no hp rising effect any more to 4000rpm.
