Another thing I noticed is that the engine's sound itself (not the turbo) as also changed since getting the intake, what I could best describe as being 'more pronounced', as if the sound quality has increased or something. Or maybe it's ever so slightly louder. Or maybe just placebo  :stupid:

On a side note, the cone filter must be bouncing of the hot coolant pipe right next to it, as the plastic body of the filter looks like it's melted a tiny bit there.

Speaking of diverter valves, I still have the original diverter valve on the turbo (the rubber seal one), I was offered by the mechanic who rebuilt the turbo a Chinese Rev D one for €50 to 'hold boost better'. I declined his offer after he said there was nothing wrong my current one, and I also wasn't confident the one he was offering was good quality.

I read that the rev D one hold boost a bit worse but is much more reliable, so why would he suggest Rev D has better performance? I'd be more inclined to get the Rev G if I have performance in mind. Is the original diverter valve really that bad?

Yeah that's normal as the entire induction system has changed.

I've never had any problems with Rev D diverters but the GFB DV+ is the best one to use, but does need periodic maintenance.  He's probably recommending it because being plastic, it doesn't split like the A and G. There is no performance advantage between A, D and G but the GFB DV+ does improve off-boost response a bit.

@Pudding I want to take back what I said earlier about the sound not being so audible from the outside.

I had a friend drive my car in a parking lot while I stood outside and yes, it's absolutely audible, much louder from outside than I had anticipated.

So yes, it's Chavvy, but I still love it :smiley:

To be fair, the Bugatti Chiron Pur Sport makes all kinds of whooshes, chuffs and pshhhhts, and people love that about it, so consider your car a pint sized Chiron  :happy2: :grin:
