Oil pickup test results
Hi guys,
I finally got to do the oil pickup tests with the original 19mm (3/4") pickup Chris from Killer B sent me. I did the tests on the same day, same oil, same process. I changed the outlet pressure port to the stock switch location because it seemed more consistent than on the crank passage. Stock: Killer B 19mm (3/4"): Modified Killer B 22mm (1"): And this is the results graph: As you can see outlet pressures are close but inlet pressures not so much. Killer B's is good for most of the improvement and will probably have even higher inlet pressures when used in a stock engine with tight clearances. I think Killer B's will be enough for 99% of the people and for those using loose clearances with more flow it's not that hard to cut the 3/4" pipe and weld a 1" pipe in the same location (much easier that what we had to do). It's hard to know if it's worth it but any positive displacement pump will always perform better with a higher inlet pressure. That's why I would recommend to anyone to get the Killer B pickup which already does a lot in that regard. Any well fabricated less restrictive (straight 3/4" at least) will work, please don't think I have any particular interest with Killer B, but they were the only ones that had what I was looking for (and top quality) and Chris was kind enough to send me one for testing. My engine has about 50 hard laps in our local track and a lot of very spirited driving and sliding around, all with clean oil and filters afterwards so I feel confident it will endure whatever comes. Touch on wood

Hate to Necro a thread like this... But would like to know if anybody is using the Reimax High capacity pump in conjunction with the Killer B? I have minor timing cover porting, not as dramatic as OP but I'm building my motor to hopefully never open back up, and was curious your thoughts puting both those parts together along with maybe porting a lil further?

But my goal with this motor is to never open it back up ever again (knock on wood) even with 10-12 psi with flex fuel on my "go" map (7-10 on my "safety" map) that being the case im more than happy to get the upgraded pump, if it'll help me.... But I'm hoping not toooo spend much time north of about 6500rpm. Pickup tube for sure, and pump gears only if they play nice with the pickup tube. Sent from my Pixel 3 using Tapatalk |

Also grooved main and enlarged crossdrilling to .250 on #3 main of the crankshaft. 30 row oil cooler with its own oil pump. Probably forgot some of my mods. I have around 95lbs at 8000rpm at ~220f oil. I also run 10w 60 castrol TWS and the tall blue oil filter. The tall blue oil filter susposed to have the most filter area of subaru oil filters. gt4202r ~12 lbs runs extremely strong for such low boost. Last edited by solidsnake11; 09-26-2019 at 12:33 PM. |

I modified a scavenge pump from the WRX. Pump has 6an fittings welded to it. 6an welded to the oil pan, to pick up oil, then though the pump, oil cooler and then returns in the front cover. Last edited by solidsnake11; 09-26-2019 at 12:31 PM. |

This is a bleeder...
Quote:
This engine a bleeder. The image here that points the little pin that's pressed in in the above hole on top of the plunger it's a oil restrictor. It is a hollow pin that's pressed into the orifice just above the plunger. If you want to run a small experiment just cover the inlet hole on top with your finger and add some 30 weight oil into where here many feeds the turbo drain line. The oil will start coming out from the said pIN. I believe ot feeds the timing chain, however, thee amounts of oil that flows through the orifice or oil restrictor is pretty significant. And just like it the other restricting areas this could be addressed and it could tapped and drill. Maybe an oil restrictor being similar to a ball bearing turbo oil restrictor or smaller. Anyways thank you for Killer B I do have that pick up tube. Also, I did the Remax regular size oil pump and addressed many of The Kinks mentioned. Lastly, When installing the oil control valve, that little filter, its plastic frame should be oriented in such way that is not in the way of the oil path.

So the *15 location is where the OEM sensor is, but the *12 is where the hex cap is? Or is it something else? I'm installing an oil pressure gauge, but not sure if I should install it at the OEM sensor location, or the one at the top. At idle, how much pressure difference are you getting at idle? And at 6000 rpm, how much? Factory spec is 7.3 psi at idle and 73 psi at 6000 rpm. So.... will they translate linearly for the *12 location? |

When my motor went after recall I used an IAG short block and one of the reasons was the improvements they made to the oiling system. That along with the Killer Bee tube. Much more confidence in the motor now.
