Am I missing something here ? it appeared to me that BeauMan's original query referred to the full size replicas which I understand are under construction.
If that is the case Genghis I find it hard to see how they are going to get the weight and power even remotely close to the
250hp/2000lb limits you mention.
The first A model FW 190 weighed 3850 kg (8487lbs) and was powered by a 1550hp radial.
How much would that engine alone, or a modern equivalant, weigh ?
