Turbo insulation

[Maxgq]

I was stuffing around on Ebay and stumbled upon this http://www.ebay.com.au/itm/Turbo-Ins...ht_1825wt_1138.
I've seen this sort if stuff in magazines but never really heard of it on a patrol, whats the deal? is there actually and benefits? It says that the turbo spools faster, is that true?

The turbo heat beanie helps keep engine bay temps down but also keeps the turbo hotter, the wrap is good for stainless steel to make it cool slower so it doesn't crack but on mild steel it causes cracks. Its really only worth it if your heat shield is missing IMO

Not worth it. Ceramic coating is the way to go.

Anything you can do to maintain heat in the system upto the turbine is good.
More heat, better corrected gas flow for more drive on the turbine, so yes it should spool a little quicker and be more effecient.
I have everything wrapped, including my exhaust for about half its length.
Ceramic coating does the same thing.

Do you have any issues with the wrapping retaining moisture? While the point you make is good I have seen exhausts wrapped in that turbo beanie exhaust insulation stuff and once wet holds onto a bit of moisture and the exhaust condition goes down hill. I know it's only minor but something to think about possibly.

To be honest I have never had a exhaust on long enough to notice anything.
Changing turbo on the weekend, I will have to unwrap the dump, I'll have a look.
No issues with moisture, it all dries fairly quickly once running.

I know its a different situation but on the generators at work the have that wrapping on the dump and exhaust (which is flexy pipe), and in less than 18 month and about 5000 hours of service the flexy pipe has pretty much desinterated. The flexy pipe is a lot thinner material, so at a guess a decent exhaust should last a fair bit longer??

Marty, what kind of turbo are you getting???

Hmmmm still Garrett based on a 2871.
Billet 71mm compressor wheel with extended tip, normal 6x6 blade configuration not full blade style.
Modified 53.9mm (standard GT28) turbine wheel.
Hopefully gain about 2-400rpm in spool and about 10-15% in airflow.
Hopefully have 30-35psi by 2000rpm, and pull like a 14yr old from 1400rpm instead of the 1700rpm now that it really gets into it, that's the goal anyway.
Not chasing HP really just torque, but if it makes a extra 20hp to give me 300rwhp, happy days.
750nm+ is the goal really.
Fingers crossed.

What engine is it?

[Bambill]

TD42.

Off topic from your question, sorry about that.
