Ceramic Turbines?

[tpunx99GSX]

Does anyone know of what turbos come with Ceramic Turbines? I was reading up on turbos on howstuffworks.com and saw that this is a good option because its lighter so spoolup is faster.

They are nowhere near as cool as styrafoam turbines.

Some Skylines had ceramic turbine wheels, as well as plastic compressor wheels.They are very fragile, and like to shatter

i was reading in one of my turbo mags, i think it was a skyline, or maybe a supra, i dont know, but they had to change to bigger turbos, cause the stock ones on this car like to shatter at about 13psi and higher. it would be good for spool, but not max power probably.

The Skyline BNR34 has a pair of GT25C100s which are ceramic Dual BB. Like said above they are for responce and spool. Nissan dealers offer a pair of Nismo LM turbos as an upgrade, they are metal. Draw your own conclusions.

Its the plastic compressor wheels that shatter at 12+ psi boost levels, not the ceramic turbine wheels

The EVO's I believe had this option at some point. As well as titanium shafts and compressor wheel. The titanium was for light weight and superior strength. The ceramic is not only for lightweight, but the main advantage was the fact that not as much heat would be transfered into the turbo. The heat would stay in the exhaust. And if anyone knows the theory of exhaust velocity and heat transfer (read up on exhaust wrap) you would see the reasoning. But I would personally think the extra cost would not neccesitate the possible power/response gain.

Similar to the EVO 7+ sodium filled exhaust valves.

I doubt very much heat is transfered into the turbo through the exhaust wheel, regardless of what material it's made of.Even if it did insulate somewhat, with the amount of heat conducted through the other parts it wouldn't even matter.Reduced mass is pretty much the only benefit of a ceramic turbine wheel

Yeah, the amount of heat transfered through the center housing is going to be way more than anything transfered through the turbo shaft.

Also the Buick GNX which was built by McLaren (sp?) had a turbo with ceramic wheels.
