Its a fair cop guv....I was inattentive when I pulled the numbers from the wrong side of the graph.
It changes nothing though, the principles remain the same.
Increasing the RB clearance does allow an easier escape for the supplied oil such that the flow out of the bearings increases approx some fourfold (not double as you mistakenly noted - but I won't go on about it). The consequence being a 4% drop in oil pressure for the whole lubrication system.
Equally it remains correct that increasing bearing clearance will change (non-beneficially) the distribution of pressure over the bearing surface and increase the peak pressure. |
The peak film pressure will not be an issue at this clearance level. With the development t of the BE Bearings for the S65, no one reinvented the wheel and did anything that was experimental or risky. BE Bearings put the S65/S85 at a clearance level that is recommended by mechanical engineers, engine builders, bearing manufacturers, and is used by a vast majority of OEM's
The only concern with BE Bearings from the beginning was, how much of an oil pressure drop would be seen once the bearings were installed? With this data we have answered this question and the results are even better than what we expected.
You can keep prodding and poking all you like but all it is doing is making you look silly. You are suggesting that a rod bearing set at best practice clearance could cause some serious issue in an ICE.
