The DB-605L engine was destined for this aircraft, reportedly developing some 1700PS for take off, without boost (designed for around 2000PS with MW-50). It was derived from the 605D and fitted with a two-stage hydraulic supercharger, probably developing around 1250PS at 9km, or 1700PS under boost at 8km. Combat at 5-7km would be in the order of the ASC engine, around 1800PS under boost at 5km, whilst at higher altitude it would really give enemy pilots something to worry about.

I'm guessing a top speed in the vicinity of 730km/h. Climb rate, I'd say would be the biggest design goal, probably 8min to 8km.
