Oil system diagram, and oil cooler installation & routing Options

[stugray]

I would like to design a dry-sump type of system for my race car.

One thing I have found is that diagrams that show how the stock system works and how to modify it for other parts (coolers, dry sump, "full flow",etc) are hard to find.
So I made this diagram in Visio (CAD-like) so I can move parts around and ask the proper questions.

Does anyone have any suggestions or comments about making the diagram 100% correct before I start trying to modify it?

I could provide the original file, but not too many out there have visio.

My next step is to get out a spare case so I can see EXACTLY where these parts go, exactly what any adapter might look like, and identify where all of the galley plugs would be in the diagram.

So I went ahead and used the car for one season (part of one anyway) with the new coolers in the front.
It worked very well. Almost too good.
Even after a hard 20 minute race I rarely saw much over 220.

This is with the dual front coolers in under the headlight buckets venting through the fenderwells.

Hole through front with tunnel and holes through fender:

I have this currently just plumbed into the system with 12AN directly with a sandwich adapter at the oil filter.

Next will be to include a thermostat and remove the sandwich adapter.
And add an accusump oil accumulator.
I chose to go with Tangerine Racing's oil cooler block off plate.
It has 3/8 female pipe threads.
I converted those to 10AN between the engine and the thermostat and to the accusump.
The output side of the thermostat has 12AN adapters to go to the coolers.

Here's the bracket I made up to hold the (massive) thermostat with the associated plumbing.
I chose to include a one-way check valve between the engine high pressure input line and the thermostat.
Then the accusump feeds straight into the cooler block off plate.
So if I blow an oil cooler (most likely failure scenario) the accusump wont just dump all the oil out on the ground.
The check valve will force the reserve into the engine.

(It sure is nice to have a spare engine and stand laying around :-)
Here's a view as if you were laying under the car:

near the top of the pic is the line out from the engine to the thermostat.
middle line is routed over to the accusump.
lower line is the return from the thermostat, and you can see the check valve.

The middle & lower line combine with a tee and feed into the engine IN line (would have been out from stock cooler).

Here are some more pics:

Here's the side out from the thermostat where the coolers will go in:

I have had that mess up under the car and it will fit once the stock cooler comes out.
I also have to contend with Murphy's law: The absoulte perfect location for all of this plumbing is where the rear suspension ear reinforcement bar crosses the engine bay to the firewall.
Makes the placement very tricky...

I hope to put it on the car this winter, but no rush.
I'll get more pics as I do that.

I will also have to add electric fans to the front coolers, but I think I have just enough room left to make it work under the headlight buckets.
