Journal Bearing Vs Ceramic Ball Bearing Turbo

In fact some professional drivers of garrett ball bearing turbocharged engines report that they feel like they are driving a big normally aspirated engine.

Journal bearing vs ceramic ball bearing turbo.

Back in the early turbo days turbo lag was so bad that drivers used to hit the throttle a full 1 3 seconds before it was time to accelerate as. This driving style allows my non ball bearing journal bearing turbo to negate the advantage of the ball bearing turbo but i get the reliability of the journal bearing turbo. I do believe that on a lower boost application you can strike the right balance between size and response but on a larger high hp setup with larger turbo. This produces an improved response that can be converted to quicker 0 60 mph speed.

However a ball bearing cartridge is the latest affordable ball bearing technology providing much momentous performance enhancements to a turbocharger. This is a teardown and rebuild of both type of turbos step by step. With the garrett ball bearing cartridge the rotor group is entirely supported by the ball bearings maximizing efficiency performance and durability. As we know the journal bearing has long been the strength of a turbocharger and is still currently used within most turbochargers.

In addition oil flow for ball bearing systems is required to be lower than that of full floating hydrodynamic bearings. Journal bearing vs ball bearing. 1 longer cool down time for journal bearing turbo. The old days are over.

Garrett ball bearing turbochargers spool up 15 faster than traditional journal bearings. Seeing the difference in how easily a journal bearing spins vs a ball bearing isnt quite fair when you are doing a bench comparison since you arent running hot oil through the journal bearing.

My con reasons to using a journal vs ball bearing are as follows. Check out our newest video.
