Rollerbearing turbo

[Blue Mule]

pros and con please

 

[Barryd]

Much faster spin up over one with a 270 or 360 deg bearing.

Much less lag

Supposed to be more reliable.

VERY EXPENSIVE compared to conventional bearing turbos.

hmmmmmmmmmmmmmm

anyway

Roller bearing turbos comes with 360 degree thrust bearing, or they should do.

Anyway, benifits are increased response and reduced spool up time.

Reliabilty, well in a way they are, as a plain bearing turbo especially one thats got a crap oil feed with groove the shaft in no time.

 

[Blue Mule]

And construction wise, whats the main difference between rollerbearing and normal turbo?

 

[Chris_H]

centre housing is machined out to fit the roller bearings in basically.

 

[Blue Mule]

Are those roller bearings made on ceramic basis?

 

[Chris_H]

not usually, you can get then though. Like ceramic wheel bearings etc you usually need to ask.

 

[jabba]

ceramics will pop with pissy amounts of boost thou so dont bother unless its a low boosting unit your after.

 

[Chris_H]

how so? Better tell the rally boys this new info! And tell them that their wheelbearings wont last either.

 

[jabba]

standard ceramics like ones on supras etc wont take the same amounts of boost as the normal equivilant.

the blades are lighter but no as strong so i hear from various sources.

ps rally technology is obviously gonna do better isnt it! ill give them a bell anyway thou.
