THE TRUTH About Ball Bearing vs Journal Bearing Turbochargers! (Robert at Forced Performance)

What happens here

The speaker then showcases a XonaRotor turbocharger, specifically highlighting its large water jacket designed for superior thermal management. This water jacket encircles the entire bearing cartridge, providing significant cooling capacity. This design enables the turbo to be operated at 100% duty cycle, as indicated by its pounds-per-minute rating, for extended periods (e.g., 24 hours a day, 7 days a week for a year) without premature failure due to heat buildup. This demonstrates how proper water cooling can address a major limitation of ball bearing turbos and allow for motorsport-grade performance.

Goal: Showcase a water-cooled turbo design and its benefits for thermal management.

section image of this you see how big that water jacket is it's one of the huge focuses of this product is dealing with 24-hour steady-state thermal loading um we this is we consider this a motor sports grade turbocharger so this could be operated in a motor sports type manner with full 100 duty cycle operation on boost pressure that's what the that's what the pound-a-minute ratings indicate you're you're being told what your 100 duty cycle operating flow rate for the limit for the turbo is so you see a turbocharger like this this is uh this is a 8269 64s these are very popular 800 horsepower turbocharger on four and five cell under six owner motors uh this turbo charger is 82 pound a minute that means that you could flow 82 pound a minute out of this turbo charger 24 hours a day seven days a week and we expect that it would still operate for a year that way that's pretty cool that's how big the coolant jacket is that's in it it deals with heat and it extracts the heat that good it's quite calculatable to know whether or not you can handle the thermal load or not i thought of my pay grade i didn't even know my turbo needed to be hooked up to water but it lasts a lot longer it'll last a lot longer does that did the tahoe have water lines running to it sure does i thought i wasn't sure if that was like us yeah i was like what is that because the prototype turbo that i'm using uh on the tahoe actually has a garrett 42r bearing housing so uh i'm using a ball bearing turbo on the tahoe just so i don't have anything else to worry about other than just dealing with what i'm changing aerodynamically and it's form factor compatible for both my first level 7875 uh fat form factor stuff and the mid grade 75 82 stuff for the next bump up those are both t4 flanged
