Just wondering if anyone has upgraded to an aftermarket Blow Off Valve on their turbo? Obviously they're only usefull on manuals.
I saw an add today for Herrod's BOV and wondered what it sounded like? I know relatively all of them have the same effect, only sound differs. I'm after one (when XR6T is ordered), but don't like the schweppes performance ones (*psssssss*). I prefer the more subtle flutter sound. At the end of the day i'll be after one for it's performance attributes mainly, although they'll be less of an advantage on a low boost charger.
But is it effective? My old man had an S13 Turbo Silvia, they have a factory bov like all cars but it was useless. Still lag between gears.
Plus, i don't mind the sound of some blow off valves, just not the ricer schweppes ones....
Doesn't the throttle body stay open whilst the auto changes gears?
Sorry, I'm getting old.
My point was related to the original purpose of a BOV and the fact that it becomes useful when in manual performance mode in an SSS and you go hard then back off, the trans won't change up a gear like a regular auto, not the ricer effect of having the thing open everytime you change gears even if boost is low.

I don't have one yet, as you can see from my sig (will be ordering sson depending on this bloody BA2 rumour). You no doubt know but after market higher volume bov's are effective on manual cars because when you change gears, the throttle body closes as you release the accelerator and press the clutch. Thus causing backpressure in the intake system and flowing air back at the turbine slowing it down, so when you engage the next gear there is that second lag as the turbo try's to spool back up. I'm assuming because the XR6T is low boost, the factory bov is probably adequate, when you turn up the wick on the other hand, depending on the volume allowed to be expelled by the factory unit, a larger one will definately improve manual performance.
I appreciate everyones opinion on B.O.V's in general but no-ones actually answered the question...... I'm assuming this means no-one's changed theirs yet.
