Don't think Harvey Gibbs had any problems until he went over 700bhp and 8000rpm so had to add a second pot or something.
Pretty sure his 600bhp engine only had the simple wrc breather set up though.

Mike Rainbird will know for sure, so would be worth a pm.

I think it was AG who told me that over 500-600bhp they are not the best and chuck oil out or something along them lines

On a 2.0l they're perfect, the last engine in the escos was 613bhp at 8k rpm and often past the 9k Mark with not a whisper out the breather!

Move onto the 2.2l and they do struggle and something extra/different is needed
