Hey all, on my Subaru I noticed I have a whistling sound when from 60km an hour onwards, below that I don't hear it. I used to hear it from 80km onwards but now it's 60km. It does seem to get louder then plateau's, I thought maybe it's the wheel bearings but I got them replaced about 70,000km ago, unless the mechanic put cheap ones on. What would you guys lean towards it being? Also when going over small bumps and especially when I'm turning the wheel on bumps I can hear like a twitching sound I think from the rear passenger side, maybe the strut? 

I know the rear of the car itself has been squeaky probably since I bought it (separate issue), but I've never fixed it as I generally don't have people sitting in the back and it's not overly noticeable unless I go over bumps with people in the back or if I'm driving myself but turn into a carpark ramp to go up the parking.

You seriously want us to attempt to diagnose odd sounds over the internet?

To be fair something like every second engine issue thread starts with a recording of odd noises happening in the engine bay, no? In that sense I'd say having a recording would be good for a start.

Yeah, but when it's happening at 60+ km/h, good luck trying to get a recording that we can hear anything over the wind roar.

Could still be wheel bearings. Or a diff? Dunno if that's a whistle, probably more a whir.

Sounds like the rear is unrelated? Hard to diagnose anything with the amount of info though. YOu could get under the back and just check everything is tight ?

Bearings got replaced (could have been cheap ones, though I am leaning towards it), will get it checked out one of these days. Doubt it's the diff, can't hear it on passenger side only driver side.

      Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 🤔

      If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.

      In the US almost everything is E10. It can't exceed 10% by much or fuel systems have trouble adapting. At the same time because MTBE, MMT, and TEL are all banned they need as much ethanol in it as possible to boost octane.

      I was mostly jesting. In my experience (and probably only my experience) the R34 GTT physical airbox space is actually too small to flow the amount of power it wanted. By sealing the box, I made it so it could only be fed by the ducts themselves. So you can seal it up and get nice cold air which IS good, but at a certain crossover point: More Hot Air > Less Cold Air I don't think you're at this point. In my case merely ducting the hot air intake with a very focused set of ducts counteracts the fact it's in a V8 engine bay. More cold air obviously best. The solution looks great.
