Test Drive Turbo Whine

One of the guys over here took a Supra for a test drive , Whine sound normal to you. I dont think it is as loud in mine

She is a Jspec 183km

That doesn't sound like mine but mine has a much lower mileage.

didnt sound like mine and i had 150,000 miles on them, before i went hybrid and mine have broken fins,is it me or do they come on late as well

Doe not sound like mine either, just sounds like the 2nd tubbie is coming in not the first

i thought it looked like the 1st come on strong about 3500 i thought it was abit late i might be wrong.

My bad, 2nd tubbie comes in at 4500 got mixed up

Maybe TTC mode?

Sounds a bit like the one I test drove yesterday. Its not TTC though, sounds more like the first tubby is on its way IMO.

To me it is too high pitched and I dont know about anybody else but the whine in mine is more prodominant within the first tubbie; once the 2nd tubbie goes online between 3500 rpm-4000, the whine is hard to hear (may its the waste gate, louder induction noise dampening it out)

This car the whine seems to get louder the higher you rev; but the whine is too loud and high pitched for me!

Id defiantly say its an issue/problem with the first turbo as the way you have described it points to that.

In the video nothing happens till 3500rpm, I reckon you dont hear any whine in the low revs becasuse not enough exhaust gas pressue is generated to spool the knackered Tubbie 1 but higher up the revs , the extra pressure spools tubbie 1. Due to it being knackered it whines like a Be-ach

Sounds logical?

It does yes but if it isnt spooling the number 1 turbo till 3500 then there's another alarming issue at work here, more than likely VSV's. Although 3500 revs for spool up is about right for a TTC mod.

Still doesn't get around the fact one of the tubbies is in pain

Just seen this in the check before buying a Supra guide off here; it ties in with how my car goes ; so the one in the Video ; something is wrong

When you drive the car, the first turbo should be noticeable as a whistle, and the 2nd

turbo should come in at 3800-4000rpm. You shouldn't be able to hear either turbo at high

rpm. The engine should be louder! It's normal to get a slight hesitation as the 2nd turbo

comes in but it should be very minor.

Good call VSV's ; all in all I think something is wrong with her and he needs to stay away unless he can get a Supra Specialest to give it the once over.

I don't think any of my turbos made that whineing sound and remember I murdered my original jap ones which were still boosting away albeit down on power

Mine whistles like a jet but ive got a really short induction pipe and an aftermarket filter

Not like that, that's sounds rough!

So mines not like that then? Cecil said they sounded different too, Dam my old ears

Probably a silly question but was the stereo turned on at the time? The whine sounds similar to the feedback you can get through speakers if the stereo is badly wired in.

No wasnt turned on ; its against the etiquette of test driving
