My Turbosmart Kompact plumb back BOV just arrived, it's amazingly solid compared to the light plastic factory unit.
Now I just need to source a replacement 34mm boost side inlet tube (sent an email to Turbosmart already) so I don't need to keep using the dodgy reducer that currently fitted to the factory BOV......
Interesting variation on the function compared to the factory unit too. The factory BOV has airflow running into the side of the piston whereas the Turbosmart unit runs towards the top of the pistion. The factory way of doing it, I would have thought, would make the piston prone to sticking with higher airflows (pushing the piston sideways against the wall of the BOV) and is probably why it has some difficulties with higher boost levels.
Anyway, I'll wait until I hear back from Turbosmart about the replacement 34mm fitting before installing the new beastie.
