can any one help me, i gotta mate who seams to think the mitsubishi evo 6 mackinen edition comes with a carbon fibre turbo...... i told him that it would burn up and fall apart within hours but he thinks its stronger than metal, even though when its hard pushed the turbo casing can glow red hot! now can any one back me up and say that you cant get a carbon fibre turbo, maybe a surrond for it or a cover but not a turbo. thanxs every one

You cant get carbon fibre turbos. They sometimes reach 900 degrees so I dont think it would last very long!! Maybe a cover.

The new Misti Evo Rally edition (or something) comes with an aluminium roof if that helps and they come with various CF bits.

does he actually mean a carbon based ceramic - that would withstand heat temperatures above the temperature of most metals and could be comressed and formed as a turbing wheel

y would it not be possible? F1 cars use carbon fibre brakes disks

Brakes don't reach the same tempersture as a turbocharger.

Carbon fibre is made by building layer upon laer of a carbon gauze into a resin mixture and then heating in an autoclave.

The resin will be a thermosetting plastic and won't melt again.

However I am 99% sure that the resin will start burning at turbo temperature and it could even catch fire!

Yeh but what sort of aerodynamics do f1 cars have.... they probably have cooling from high pressure channels of air.

I don't know, i suppose it is possible with very expensive f1 technology....like £500,000 worth of carbon fibre to do it.

What would be the point in fitting that to an evo....would it really make that much of a difference, it's not THAT heavy.

Also from an engineering perspective the carbon is going to insulate the turbo and thats not what you want either!

my view is that your mate has been fooled. on paper, you could make a turbo from carbon fibre composites, the materials used in the construction of carbon/ceramic brake disks are not what you'd use anyway, as these are formulated to resist abrasion and are designed to operate at very high temperatures only, when they are cold, there crap. if you could mould the required shape from carbon fibre, then machine it, then fit all the hardware into it so you could mount the exhaust manifold etc, then yes, in theory you could, but moulding the complex shape of a turbo housing would be an absolute nightmare, one which is virtually imposible to achive, and the weight saving you'd gain from a carbon fibre turbo housing would not be significant enough to justify spending the money developing it.
Carbon fibre is stronger than steel, if engineered correct, up to three times stronger, having said that, under the heat it would warp considerably.

Hope that clears it up,

Hows that interior Sam?

i dunno lads im not disagreeing with anyone but in f1 there making gearboxs and chasis, brake disks and pads out of this stuff

i know heat is the main issues here but i think its quit durable

having said that the brakes on a f1 car is only meant to last for 1 grand prix which is only 2-3 hrs so maybe the the turbos are not meant for everyday use.

Yup, the Evo extreme, and so im guessing Makkinen Evo came with ceramic coated turbine blades .
