With the smallish fuel set up you've got I wouldnt go more than 500 at the wheels (the biggest limiter is your pump).

The engine though should be able to hold 800 without much stress. As long as the brging clearances were kept on the loose side you should be in for a hell of a ride. The biggest killer of RBs is the oil clearances, most builders make them too tight. And FYI the stock clearances are too tight for a high winding, high power engine. I hope your builder knew that. If he did stock clearances, dont go over 500 engine hp for at least 10,000km.
