has anyone used of this...

my turbo sits close to the bodywork and looking to insulate it
i will be running quite aggressive als, launch control (anything else that causes excessive heat lol)

was also thinking about getting the hot side of turbo and exhaust ceramic coated

but the above is a cheaper option

 

they work well also decrease lag as hotter particles move faster, but reduce turbo life due to insulating the heat hence turbo components get hotter!

 

how does that work? - the company selling these itself does not make that claim, you think they would mention this desirable quality of the product if this is correct.

 

1. By retaining heat within the turbine, the hot and expanding gasses will have the effect of increasing thermal efficiency of the turbine design.
this first in the list on their site

 

so do the pro's out weigh the cons? how much is turbo life reduced?

would i better off ceramic coating or would i be achieving the same result

 

I read that but realistically how much improvement does this make to overall performance of the turbo, the reason I asked this is that if it was all benefit I would have thought tuners would be using such products more.

So the first question is the improvement in thermal efficiency noticeable? - can you feel it or measure it as a BHP increase, if so what kind of numbers are we talking here.

Why are tuners not using it more widely ?

What's the down sides of the product ?

 

My personal feeling on this kind of thing is that retaining the heat inside the turbo and exhaust components will cause a build up of heat inside the head which could end in valve failure, especially since CVH's run such huge valves.

 

downsides would be that the extra heat you putting into the turbo will deteriate the mechanicals of it quicker


thats about all i can see for now

 

o didnt think of that mr c


as a tuner then what would you recommend? c coating? heat jacket? or leave as is


i have heat shield where needed

 

we use these at work and they work very well

for 80 quid its a sound investment

 

im gonna go see tommy field so will ask his advice

 

Mark Shead has experienced bearing failures on roller-bearing turbos with these fitted.....

 

mine is roller bearing also


not a gt series but still

 

alot of people have experienced bearing failures on roller bearing turbos without one of these fitted

 

But not of the "fried bearing" type failure .

 

perhaps they could use some high temp plastic in the bearing cages

 

you say that as a joke but it could be done

 

No I did not use this on a RB turbo only a Journal bearing and it cooked it,
The BB turbos I use have been very reliable infact much better than rebiult T3/T4 turbo's.

I have one, mine was from AET Turbos though, as the Owens ones are way too small for my Turbo.

Know plenty of people who run em, nobody has had problems yet, and work well, but others have had problems.
Swings and roundabouts, same as most stuff.
