You do know that element tuning documented this a long time ago when they first started building the FA. They have a few threads on here but they don't ever go into their solution as they say it is proprietary. They were making enough pressure to support 9k RPM boosted.

Please link where they talk about beveling the oil gallery into the bearing groove.
Thanks ahead of time.

I have 90lbs of oil pressure at 8000rpm with 210f oil temperature I have enough for 9000 rpms just don't have cams to benefit turning that high.

As I said, they don't say what they did cause they claim it is proprietary. The title of your thread is "more proof that the #3 main needs modified." I am pointing out that this has been common knowledge for a while.

It is nice to have someone openly document everything they did to improve oiling for this motor.

I agree, but why not add it to the thread he already has so it is in one place instead of creating another thread :iono:

Yeah. I'm not a fan of "shhhh... seeeecrets" I see exactly what you're talking about in that screen cap. If I were to go for any extra torque, my first step would be to reproduce your work. Thanks for sharing!

That and this motor does not prioritize oiling the mains which compounds the issue.

I saw where your restricted flow to the heads(well, primarily the driver side) but not where that change was made.

It's the title of the thread that illiceted my ****ish response. I read that and went, "no shit."

I appreciate all the info you have posted, at your own expense. My goals are significantly different than yours but along the same lines. I will be posting the teardown and buildup of mine once I have accumulated all the parts. Remember, work is not without criticism, and I expect a lot once I post up mine. :cheers:

Can someone please explain what's going on here?
I have no idea what I'm looking at in the picture in the OP

To simplify the above explanation. The crank rides on 5 main bearings. Main #1 feeds oil to rod #1. Main #3 feeds oil to rods 2 & 3. Main #5 feeds oil to rod number 4. So the idea is to improve the supply of oil to main #3 as those rods commonly spin bearings as the main has to feed two rods as opposed to the others just feeding one.
