There are a few that are over 200bhp, yoof for example.

And 7k on the engine? What did you do to it?

~185bhp give or take a few ponies for different rolling roads, providing you've had it mapped that is and the cam's is 252/276 Schrick.

A true 200bhp isn't hard to do, bolt a K03 onto your engine and you'll be over 200.
