Has anyone successfully modified the OEM oil pump and housing?
With any high G-force applications (Drag, Road Racing) causing the pickup to be exposed, this eventually leads to the degradation and destruction of the oil pump.
Frontline fabrication has made a completely new pump, but I dont want to spend that kind of budget for a pump.

So the gear side faces eventually eat into the aluminium housing, causing the clearances to become too great and the oil pressure is reduced.
Jafromobile (https://www.youtube.com/user/Jafromobile/videos) covers these issues with his very informative video's.
This one shows the clearances being too large and the pump is junk:

So it seems - that oil starvation causes the oil pump to become damaged and eventually die, rather than oil starvation damaging the engine.

If we can develop a way to support the gears correctly so they can withstand some starvation with damage, this will prolong the life of the pump and ultimately the engine.

Any ideas?

 

There's not room to mod the factory cover.

You can use the ER under Drive oil pump pulley, and get a high capacity baffled oil pan like the Racefab or a Moroso.

 

Yup i've been looking into the English Racing gear, makes sense.
I've got a Racefab sump already also.

What about using 1G DSM straight cut gears to reduce the side loading on the housing also?

 

The straight cut gears aren't as strong.

I sent my oil pump gears to TRE and he detailed, shot peened and REM ISF polished.

With the ER gear and baffled pan you'll be fine.

 

How does the strength of the gears effect the pumps ability to live and not wear out?

I have access to ISF polishing, I can get that done.

What about hard anodising the oil pump housings? This would increase the wear resistance?

 

Another idea - external oil pressure regulator.
Would be easy to do and it means you can put the "excess" dumped oil wherever you like - like into the front winged section of the Racefab sump.

Here is an oil pressure scatter graph showing roughly what the oil system looks like.
You have the steep initial rise of oil pressure, this is the pump working with the regulator shut.
Then on my setup the regulator starts to open around the 2500rpm mark.
The excess oil is just dumped back into the pan, towards the rear of the sump (which helps no one).

 

You're over thinking this. I have two customer cars making 850whp running 9's revving to 9300rpm with the parts I suggested for the stock oil pump.

Do what I've suggested to the stock pump, or get an FF Fab pump, or go dry sump.

The only thing that kills the stock pump is it sucking in air. The issue is lack of baffling in the pan, and the pump spinning too fast and draining the pan (hence the underdrive gear).

Hard anodizing won't do anything, the steel pump gears will go straight through it if the oil film isn't there.

 

Yeah, I think that by the time you go through the hours and a$$pain of re-designing the stock oil pump, you may as well just buy an upgraded oil pump. But as letsgetthisdone says, you're probably better off addressing oil starve issues. Maybe just throw an accusump in there and call it good.
