Full flow oil system, is this bs or what? Options

[kdfoust]

I'll be getting my case back from RIMCO pretty soon and I'm thinking about the oil system. I'm planning to run a 30mm Schradeck (sp?) pump. I've read a number of threads about "full flow" oiling for TIV engines and I guess I don't get it.

For full flow on a TIV you do what?
Plug or modify the oil filter bypass valve that I've circled below? Then what?
Modify the oil pressure relief valve (new spring I guess) to accomodate higher pressure? Then what?

At what pressure does the stock cooler blow open like a pan of Pop-Magic pop corn?

TIA,
Kevin

Method 1) Plug the existing oil filter bypass valve. Compensate on the oil pressure relief valve with a stronger(stretching exisiting also) spring.

OK... the oil filter bypass valve is just a safe guard in case the filter becomes plugged. All modern filters have this function built in and if you have a major failure (such as a flat cam) it will send metal shards straight to the bearings. There is less chance of this happening with the filter bypass disabled.

The stronger pressure relief spring is to compensate for the increased oil pressure of the 30mm pump.

Method 2) Some sort of external plate or plumbing that takes the factory filter housing away and sends oil to an external filter and/or cooler. Does this mean that you've blocked off the factory oil cooler and completely rely on the external cooler?

No, you can do this without removing (the function) the factory oil cooler and have an external filter and/or cooler.

On the upright conversions that Jake does, he uses a Gene Berg pressure relief cover (part # GB 239), this cover makes sure that the oil pressure never exceeds the burst point of the cooler.
BUT this cover is hard to use with a stock engine mount (the part that bolts to the case), as it's in the way.

I plan to build a new (modified) mount to get around this problem. Then you do away with the stock filter housing and use a plate or fitting to return the oil.
