I saw 900 degree manifold temps regularly at the track, all with a beanie on. The car has done 6 hard track days and daily driving for many years without issue.

As long as the CHRA is water cooled you should be fine.

Thanks for clearing it up. When I baught my beanie off hpiab they said remove it after hard driving and whilst racing to reduce the risk of damage to bearings. I thought why sell me that if it Can damage the turbo.

[Manuel Kasko]

yeah exactly, what would be the use of it if you aren't using it to reduce the heat when the turbo is at its hottest

[AngryRB]

Whats the go with HPC? when I had my manifold and housing done I really couldn't tell the difference, I mean even if temps are down

1000c to 800c for example, its still bloody hot, retaining that extra heat might even cause the manifold to crack from the inside

out?? Maybe on a track car it sounds plausible but on a street car things wouldn't get hot enough??

Aparently beanies can lead to internal bearing damage if left on and raced with. No idea how. Hpc coating increases thermal efficiency in the turbo which leads to better response. Plus if you hpc coat it silver the chicks will flock... hard. But in all seriousness when I do go a steampipe manifold ill be hpc coating the manifold and turbo housing. Looks good, doesn't get that rusted look from heat, serves a purpose.

This. Just do it and rest assured it's an asset to your build. I've always HPC coated my exhaust components (if the wallet permitted I'd do the entire system ) but my turbo manifold, ex housing and dump pipe/wastegate plumb is all coated. Granted, it is still hot (but greatly reduced) and you can feel that under the engine bay... but consider this... what would it be like without it? Whilst off, definitely beneficial if you can afford it.

But he already has a beanie, so it's a total waste of cash. I would only ever recommend it for mild steel exhausts to prolong their (short) life.

DEI Beanie and DEI Ti wrap the dump (for stainless) is the best shield against heat I have found so far, and I have used most other styles of heat barriers.

[LTHLRB]

Im not saying it for heat shielding. im saying to hpc coat it to retain the heat inside the turbo exhaust to improve thermal efficiency. Yes it helps shield heat but im aiming at the heat retention in the turbo. i was running a turbo beanie untill a poorly made oil line burst and filled it full of oil. now it wont stop smoking. its like i have bob marley under my bonnet.

Hmm iv hit a wall! I bought what I was told was a gt3076 .82 rear but it does not seem to fit the wheel?!?

Here are some pics. What have a bought and maybe my turbo isn't what it should be?!?

[LTHLRB]

Is there a part number you can give to garrett to clarify?

[DriftSquad]

This is from my turbo

[Lithium]

That's a proper anti-surge GT3076R core- the turbine housing will not be a GT30 one...

[DriftSquad]

The new one I bought anyway of knowing what it is?

[GTScotT]

Do yourself a favour and ignore what the tag on the core says for a moment... Measure the turbine at its largest diameter and see if its 60mm or 56.5mm.

ARTZ had a turbo from a reputable resaler which was labelled a 3071, but when we measured up it had a 56.5mm turbine and a 76mm T04S compressor. It was more likely they had rebuilt it and simply neglected to update the tag. Or built a custom turbo from whatever they had around... Who knows.

[DriftSquad]

I don't have it with me. Is it possible the one I bought was hiflowed?

[GTScotT]

Its possible that its for a 35R, as the housings are identical on the outside. You should still measure your turbine though.

Once you measure the turbine you will know if you A: have the wrong turbo for that housing, or B: have the wrong housing for that turbo.

You must measure first.

[LTHLRB]

isnt A and B the same thing but worded differently? If the turbo is wrong for that housing that means that housing is wrong for that turbo.

[GTScotT]

True: the photo's clearly show its wrong. SO, the task is now to work out what housing he actually needs and who's responsibility the wrong housing is.

In A: the seller did nothing wrong and OP needs to wear it or ask nicely to return, in B: seller needs to give OP a refund as he misrepresented the product.

the risks you run buying miscellaneous car parts. some stuff wont fit or wont be right. happens to the best of us

[discopotato03]

Highly likely a EWG housing for a GT3582R , probably the easiest thing is to measure the ID of the housing and if it comes out a little over 61mm that sort of gives the game away . A GT30 turbine from memory measures ~ 54.9mm at the exducer (outlet diameter) so a matching housing would be that plus clearance .

[AngryRB]

taking bets on gt35 housing.. lol

did they say it came off there gt30 or they just had it randomly laying around?
