The pump would not just provide more pressure overall just more pressure sooner. The pressure gets capped off at a certain point. Unless the "Wastegate" on the b35 oil pump pressure is higher then the b34. I can upload vid of where B34 oil pressure is capped off if need be. Usually in higher rpm applications you want to slow things down since the engine is overoiling or like on SR20's they usually put a larger water pump pulley because it starts spinning the water to fast. You can have too much oil pressure, and if you are already being overoiled then a B35 pump would just make that worse.nik77356 wrote:As I have previously stated in the original post, I would like to run a B35 Oil Pan and Pump. I want to do this for multiple reasons. The B35 Oil Pan seems a bit more conducive to adding baffles, as well as the B35 Oil Pump providing more pressure due to the smaller drive gear diameter. The biggest issue I see, is that the block I am using does not have provisions for the oil pump chain tensioner. Based on this thread: http://www.mye28.com/viewtopic.php?t=119354 I should be able to run the B35 Oil Pump using part number 11 41 7 577 655, as this chain has 44 links, along with the correct number of shims to get chain tension correct (part number 11 41 1 250 562).
I don't believe there are any differences in the way oil gets from the pump into the engine between older M30/M90s and the M30B35. Has anyone experienced anything different? I will likely mock this up later this week.
I also think the head restrictors might not be needed, just a good way to catch the oil. Although your motor will be a track only motor, so unlike me you won't care about oil delivery at idle as much. Hell you could just vent it to atmosphere at the valve cover like they used too leave all the oil in the head. You have to remember that M10 race motors run to 8,000-9,000 rpm. Do 7,000rpm M10 build get block restrictors? I would call Ireland or Korman and get their take on what you should add.
"wastegate" or relief valve I'm talking about
