The ruby sapphire would be more resistant to impact and are also another 5 times harder than ceramic.
Do ceramic turbos need oil.
Couldn t take a photo for you guys.
For a true seal the best set up is two gapless rings in separate grooves.
Ball bearing turbo cores have a restrictor in the oil inlet.
August 5 2013 turbocharged engines will require more frequent maintenance such as oil changes and fresh spark plugs though they typically don t require additional service.
This means that they need a constant flow of quality engine oil to lubricate the compression valve and intake and outlet fans to reduce wear and help them perform at their best.
In this video i talk about ceramic bearings and do they need lubrication which is kinda what the title says funny that.
A lot of those cars run 6 bar of oil pressure low turbos and sump pumps.
Because they elimintate the oil they also eliminate the parisitic drag that goes with it oil cook and are more durable.
Ceramic ball turbos precautions are not to allow impact on housing and to store horizontally.
There is a down side though.
By the time you notice its leaking there is not much hope for a cheap rebuild.
Full ball bearing turbos do not need oil thats the whole point they use cermaic bearings instead of oil.
Thanks to all my patreon subs.
Well worth the money trust me.
