I've seen a sandy brown engine running 236 bhp IIRC, they were the basis of the 206 WRC engine, so yeah, 330 bhp with a 34mm restrictor 85mm liners and 88mm crank (1997 cc)
have seen those WRC engines taken to 550 bhp with larger restrictors on rallycross car (yes, they are still restricted!! 45mm afaik)
