Anyone thought of using a Turbo blanket / cover?

[tigtsi]

Hi All,
I haven't found anyone on the forum who has used or thought about using a turbo blanket / cover.
For those that don't know - it is put over the exhaust side of turbo and will keep underhood temperatures down and help keep heat contained within the turbo, helping it spool quicker.

13 years ago i used the Thermotec exhaust tape on a Jap import turbo conversion and it kept temperatures down alot, but didnt know about the turbo covers then, dont think they were widely available??

I have just rediscovered the Thermotec brand and thought the turbo covers could be an option. The link below is for a T3-T4 sized turbo - obviously too big for standard Tig turbo - BUT they also sell a generic kit that supplies the shielding material to cut down to suit your application. There are other brands around.

Just thought of some possible problems: The turbo would take longer to cool down as the heat isnt disepating??
and life of turbo maybe shortened due to excess heat?

I haven't had a good enough look at the Tig to see if it has its own metal heat sheild??

Thoughts anyone?

Thermo-Tec : T3-T4 Turbo Cover

I bought one for my TDI early on, then learnt about the perils of keeping heat in for the diesel VNT turbo's. The factory exhaust shield in my TDI is plenty good enough, helps deflect the heat without encasing it. I decided upon the strength of the stock setup to sell the beanie I had.

I haven't got one.

However i don't have any issues with the factory turbo and heat even with stage 2 and no blanket.

Hi Team_V,

It Could give you a bit extra grunt from your stage 2 with cooler intake temps and a quicker spooling turbo! - I have thought about using the heat shield material on the air intake tube that runs directly above the turbo.

Stage 2 is already on the limit off too much to handle for road use in a manual
Not sure it would help with the turbo spool up as it starts to kick in around 1750RPM and goes on full song from around 2500.

I just figured it was a thing they did on Jappo cars with huge turbo's that have a lot of lag.

Would be interested to see any data you get if you have one though.

You are probably right about mostly Jap cars with Turbo's the size of your RPF1's sitting up high in the engine bay! I remember my Jap conversion was a dog box if you didnt take off with enough rev's. Boost would hit you around 3500rpm++

Found this quote (from below link) interesting to possibly confirm my thoughts on turbo longevity using the blanket.

Thermal Products

"As these Blankets are designed to retain heat within the turbo, it may be benificial that the blanket be removed for vehicle "Garaging" as retaining the heat without the water/oil circulation may cause long term reduced life for the turbo (this is particularly relevant when used with non-water cooled plain bearing units). Although there is no documented analysis to support this theory... (we don't beleive this to be the case based on our testing and analysis)"

Probably better off keeping the intake piping cool by putting some reflective heat shield around it rather than dealing with the turbo blanket.
