Pah, all you BOV fairies :p **Runs**

I've run without a BOV for 6 months now. I've changed 1 turbo due to the oil seals letting go. The car had done 74k which is about the life expectance of the CT9 so I'm led to believe. The thing is with turbo's is that they are subject to so many variables it is impossible to pin a failure on one thing, such as running with no BOV. Exhaust gas temperature, fuel mixture, vibration, oil contamination, oil starvation, foreign object (Stone, bird, small children etc), wategate/actuator failure, the list goes on.

I've since been running a CT9b without a BOV for about 4 months (Save for a week or two here or there for a change) without any problems thus far.

Here's a vid taken ages ago on the CT9a with just mesh on the inlet and no BOV.


:rockon:

I'm going to make an intake system with a filter behind the bumper as it sounds a bit too harsh at the moment with the CT9b (It's louder than the CT9a).

volume wise imo the bailys isnt a patch on the forge nice loud crack like a whip, ssqv is also loud very unique

the ssqv has a lovely sound to it, very unusual sounding :)

well worth the £££. I had a bailey before it on my old car, and it wasn't of great quality. Used to hiss (leaking boost becuase it was starting to dump) far to early, causing it do "ssshhhhhhhhh" all the way down the motorway if you tried to do a steady 70mph...

Apparently most folk suffer from this, whether or not they notice. Plus, they're completely open on idle...

The ssqv is guaranteed not to leak under boost pressures Lmao at sophisticated I got an ssqv it sounds great I never get bored of it

I get this, thought i was the only one, i end up putting it on low boost so it dosent dump or hiss when im doign a steady speed. So BOV's such as the HKS/Blitz dont do this??? I would definalty consider changing my Baileys one if the others dont do this.... :):)
