INFO ON TURBO BLANKET [beanie]

[threedogs]

After info on the pros and cons of fitting a turbo beanie, I think it would be better for the AUX
battery ,keeping down the under bonnet temps,
does it alter EGTs at all and what about long term use can it harm the turbo at all

I've thought about one for a while too. I'll be following this.


The only negative that I am aware of is one instance an oil leak saturated the beanie which eventually caught on fire and wasn't able to be extinguished.

Did you end up finding out what size you need? I could see it raising the EGT's, but only ever so slightly because the turbo would be hotter with a beanie on its head. While it would help with under bonnet temps I think the OEM metal shroud does better than nothing.
If your worried about the aux battery, I would make a heat shield for that instead.
Did you know that Nissan made a plastic cover for the batteries and it had an air ducting tube running from the inner guard to the cover? Been thinking of getting one for my Aux battery and then covering it in a heat reflective something or other....

Do you know how long it took me to figure out what exactly that tube does ??? lol

As for the main topic...
I don't know about this. I mean, this beanie thing will just retard the heat dissipation from the turbo, making the turbo even hotter hence higher EGT's ??

I'd be too scared it will cook the turbo and you would have to have a turbo timer but IMO a battery is cheeper to replace than a turbo

I've run a turbo beanie for a couple of years with no drama and i was doing 11 and 12 hour runs with only fuel and food stops now i've taken the beanie off the schwitzer and put it on the kinu 18g.

That cover doesnt fit the bigger batteries, I have one,plus no good if snorkle fitted no tube
as for the size as the turbo is only small I think
the 150mm x 50mm one will fit about the $50 depending

@ Sherro any down side using one on a daily driver ??

Just been reading some comments from the WRX guys and the SRT Dodge boys.
seems trapping heat in a turbine is good as hot gas spools faster
As for trapping heat they say turbos are designed to glow white hot
and Id guess many here dont even see their turbos orange, me included
to make the most of it they recommend ceramic coating one side of the turbo
and wrap the dump pipe in exhaust bandage.
one guy has had one beanie and 4 turbos so they are built to last

More reading tells me its Thermodynamic meaning the more heat
you retain in the system the more energy you develop,
Anyway after what the WRX guys say I brought one
might even wrap the dump pipe after reading about Thermodynamics

Any heat lost to material is lost energy. A beanie helps but it's not quite as effective as ceramic coating. I would do both if finances allow.

As for turbos glowing this is not great. Yes they can deal with it but shit will eventually melt. Glowing turbine housings mean high heat which mean high pressure pre turbo so again you are losing that energy as all it is doing is heating up your manifold/turbine housing.

was only saying that as no one here would get temps that high I would think,
it would only happen under high rpm race conditions I would imagine.

I read somewhere of a DIY high temp coating but cant find it Doh
