You'll hear the BOV (properly referred to as the boost recirculation valve) "thunking" only when abruptly on-and-off the throttle...and usually only if the two sealing gaskets at the ends of the piston are worn. For steady state throttle while under motion, BOV's don't make any noise at all.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
