Default Turbo Shields?

Anyone using a similar titanium turbo shield as found on on this page? I called up the company and chatted for a few and they shot me a discount code for their turbo shield kits (tsdiscount) but am curious if they are even worth it. Their rep said the shield will actually help improve spool times, etc. But I don't want the sales pitch just the facts. Even with the discount its not cheap and how much will it impact underhood temps and would retaining heat actually cause the turbo to prematurely fail? I just dunno so am looking for a little guidance from the pros.

It won't increase any performance factor of the turbo, it will only make the turbine housing and CHRA hold heat longer. The turbine gets hot enough on its own, it doesn't need a blanket. I'm putting a brake duct hose pointed to my hot parts in the near future to help move air around them more.

Hustler is spot on. A heat shield can only protect something from heat damage.

A performance part? Hogwash.

Hustler is right.

While I've heard some argue that keeping the manifold and turbine housing at higher temps creates a greater temp difference across the turbine, and it makes sense theoretically, it's hogwash in practice in a dynamic situation.

All of the heat energy is created by combustion. The exhaust gases are moving at such a high velocity they hardly see any delta T from conduction with the hotside parts. While they do heat those parts, once at temp, and high mass flow rates, it takes very little energy out of the exhaust charge.

If you were optimizing performance for a motor in Formula 1 it would be worth investigating, but they don't use turbochargers anymore...

For those of us one the street and doing trackdays, increasing longevity of the turbo through lower surface temps is a better bargain.

Get a head shield to protect your plastic and painted parts though.

F1 never used the turbo blankets either. However they used v-bands, whcih makes my car on par with 1970's F1 technology. It also has 4-wheels.

Now he is going to rape you.


Turbo blankets did help me from melting stuff though. But I got mine cheap.
