Because they elimintate the oil they also eliminate the parisitic drag that goes with it oil cook and are more durable.
Do ceramic turbos need oil.
The ruby sapphire would be more resistant to impact and are also another 5 times harder than ceramic.
Well worth the money trust me.
This will seal very well.
Things to check if your turbo leaks oil.
There is a down side though.
In this video i talk about ceramic bearings and do they need lubrication which is kinda what the title says funny that.
Ceramic ball turbos precautions are not to allow impact on housing and to store horizontally.
Full ball bearing turbos do not need oil thats the whole point they use cermaic bearings instead of oil.
A lot of those cars run 6 bar of oil pressure low turbos and sump pumps.
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.
For a true seal the best set up is two gapless rings in separate grooves.
Thanks to all my patreon subs.
Couldn t take a photo for you guys.
Turbo systems are made up of moving parts which spin at incredibly high speeds and work under intense heat and pressure.
