Hydrodynamic Journal Bearing Units (oil cooled only)

These units feature the industry's latest technological advances in Journal bearing Technology. Magnum's units come with low inertia dual hydrodynamic  journal bearing technology. Manufactured out of high strength Copper-Tin alloy these "white metals" provide the highest scuffing and fatigue strength available while offering the lowest friction coefficient in comparable alloy groups.  Generally, this bearing technology offers two primary advantages for the high performance market. The first being a low price-point that best suits the needs of amateur racers and racing  enthusiast alike. Focused on wide open throttle response and serviceability this is easily the best option for the weekend hobbyist and street performance application.  When taking into account that once target boost is achieved, ball bearings of any kind offer little to no advantage in performance at full throttle. This is the clear choice for seasoned drag racers not relying on the transient efficiency that a track car would need for example when trying to get out of a corner rapidly . Another often overlooked advantage of the journal bearing CHRA unit is it's serviceability. Unlike a Ceramic Ball Bearing CHRA which in most cases is not serviceable due to its irreparable failure modes. As a result this technology focuses on meeting the performance needs of most racers while offering a low price-point and relatively inexpensive repair or replacement cost in wearing parts. It's no wonder these units carry the best warranty in our lineup and industry as a whole.

Hybrid Ceramic Ball Bearing Units (water and oil cooled)

These Magnum turbochargers are available with the optional water and oil cooled hybrid ceramic ball bearing CHRA. This technology is a step up from the entry level Journal Bearing Technology when quality, durability and performance are desired yet remaining price conscious is crucial. When it comes to Ceramic Ball Bearing Technology, they are not all created equal. This is Why Magnum Performance Turbos uses the highest quality Silicon-Nitride balls available in the industry inside its Angular contact Hybrid Ball Bearing systems. This low friction and ultra low inertia material reduces parasitic vibrations and lowers friction heat as well as lag in the CHRA. With high load anti thrust qualities it reduces thrust induced friction and stabilizes the thrust bearing increasing spool-up characteristics by 8-10% when compared to most hydrodynamic journal bearing CHRA. Ball bearings in general require significantly lesser oil supply and have been know to operate undamaged during long periods of oil scavenging. Hence whether "hybrid" or "cartridge style"  the longevity of ball bearing units is unmatched by even the most hydro-dynamic and advanced journal/thrust bearing units .
