Oil Control In Rb's For Circuit Drag Or Drift

[MutatedHero]

Which valve did you go for on the Accusump?

[fatz]

Solenoid linked to ignition

[MutatedHero]

Which PSI did you pick? Or you went with the electric valve and not EPC?

[JimmyRickard]

Is anyone else doing extended sumps other than Hi Octane?

[fatz]

Yea I will have a flashy one soon

[JimmyRickard]

Who's putting it together?

[fatz]

Cpc will have the first shortly

How is the routing on the hoses?

I'll mirror the same question and ask specifically what you are doing with the oil fill cap vapors?

[fatz]

Filler hole to sump drivers side

Catch can 2 to sump drivers side

Catch can 1 to electric pump to passengers side sump

Hey everyone, just setting up my rb30det neo at the moment, I have set up 2 -10 outlets from my cam covers on my catch can and a single -10 on the bottom of the catch can to the sump on exhaust side there has already a rear head drain mod that's been done to my engine but the return to sump ends up above the windage tray on the inlet side, wouldn't this be holding any oil trapped in the hose? should I relocate it to under the windage tray?

Also the front head drain on the exhaust side runs into the sump directly below the turbo oil return on the block, would I be best to put this line into the block and have the turbo return directly into the sump. (this line runs well above oil level) or the other way around.

Cheers in advance

Head drains are not drains. The intention is not to have oil flow down them so much as adding area for sump gases to flow upwards. We still want the oil to flow down through the block drains. If you had read this thread you would have gathered that.

Therefore the rear "drain's" return above the windage tray is not a problem, and is in fact perfectly fine, as the main requirement for the location of that end of a "drain" (actually the source end of a sump breather) is that it be above oil level.

Ditto front.

I have a 25/30 neo and flog the absolute shit out of it and it doesn't breathe a single drop of oil.

I used a single 1.2mm restrictor in front feed and blocked the rear. I drilled out the standard baffles in the cam covers, put fuel cell foam underneath and put them back in. I also used a screwdriver to enlarge the standard drain on the factory baffles.

My sump has 2x -10AN fittings welded to it ready to go if it ever starts breathing hard. But as it is right now it's perfect and the cam cover baffles are reasonably cheap and easy mod.

Also, as you are calling it a 'head drain' you obviously haven't read the last 10 pages of this thread. It's very worthwhile.

accusump was a winner at wakefield

no more flashing low oil pressure warning light on heavy braking

real test will be at ec when its loaded on a left hander

How many of you are run in gapless rings? I only seem to hear good things about them and I've even heard that they pressurise the sump a lot less.

I'm not an expert but if someone wants to add their expertise to this I would appreciate it.

[djr81]

Not many people run them. When I was buying rings I was offered them but didn't take it up because I wasn't familiar enough. THey promise to offer very little blow by which would be a huge gain for an RB26.

Pacific Engine Parts are fans of them. Give them a ring 03 9737 0717

I recently tested a 10 year old RB30 Single cam with 40,000kms on it. Had 0% - 1% leak down. Just about ripped the guys arms off when he was holding onto the bar holding the crank still. (I put 150psi into the cylinder).

They are impressive. I think when building an engine these should be considered
