Re: Building a 10,000 rpm NA engine.
Sorry it took so long Harvey had to make some parts for the factory on the mill.
Your answer,
The 2 galleries along the top are 14mm diameter, the one feeding the back bearings is the same length all the way throught to the back. No real reason why the back would run short of oil.
The outlet behind the pump that feeds the oil filter and bearing is 15mm.
I think the issue is flow.
If you think about it and I am remembering what Adam said about the oil pump. The cosworth is the same size as ours.
MY THEORY
I think the numbers tell the story a pump rotor of 12mm being 2mm more then the 4 cyclinder means the pump only has 20% more oil.
The EG33 has 7 bearings 2 more then the 4 cyclinder at 5. This means in simple terms the engine has 40% more bearings or bearings area. The even more bad news is it has 50% more power so how is 20% more oil going to do the job. A dry sump is the only way out of this one. No wonder Matt and other had bearing issues.
