Now now, BE is simply stating facts.
1) Sn/Al bearings are simply harder than Pb/Cu - this is easily verified as true. There is also a great deal of information about this available online that shows that Pb alloy bearings are superior to Pb free bearings (see attached from an RoHS exemption request made by Caterpillar)
2) Neither 088/089 nor 702/703 bearings offer adequate nominal clearance as per all major bearing manufacturer's recommendations for high RPM engines
3) 088/089 and 702/703 shells
can result in very tight tolerances based on the data collected and published
All of the data is available for your independent review. All of the raw datalog files were shared by
AutoTalent. The entire investigation was well documented and shared to the community.
As my old boss used to say" "In God I trust, everyone else show me data."
Happy motoring!
