This is where Keith needs to jump in. I think his premise was that with no boost being built (valve open and recirculating) there would be no drag normally associated as the compresssor tries to compress air. Thus, the turbo would just free-wheel and spin up in rpms. Net-net, less rotational mass to overcome when you do want to start generating boost = faster boost response.
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.
