oil starvation prevention

[Serge]

Steven warned me when i got my subaru that i should get a baffle for the oilpan.

So far ive been okay, then again i'm ran a 205 street tire all race season, but i think this spring i'll invest into some sort of solution to prevent possible engine damage (engine is crap to begin with, and i'd like to hold off a swap for as long as possible), as i might be going to a sticker street in a 225 size, maybe even an R.

so what are my options going from cheapests to most expensive?

Just run an additional litre of oil. You will be fine on an NA.

[LaszloT]

Where exactly is wazoOO, lol.

[JoeT]

The destroyer of ring lands on an NA engine is the oil that recirculates into the intake. Run a catch can at the very least prior to recirculating the blowby.

The routing should go from the valve covers to the catch can, then from the catch can to the intake.

never had a prob on 11 years of 2.5rs.... summer/racing, i just made sure i was on Full mark for oil / did more oil changes frequently.

ran years on r's especially 225-50-15 v710's and ra1 at track.

[JoeT]

But but Robin.. He's faster than you.. (JK JK) ;-)

[Lloyd]

Is a catch can free for solosprint or does it fall under the "emissions non-compliance" mod area?

I should probably set one up for next year - I only intermittently recall how bad that crankcase goop must flow crawling along those straights.

4.8 AUTHORIZED MODIFICATIONS – ZERO PIP VALUE

4.8.1 ENGINE & TRANSMISSION

.4 Catch tanks, oil filters, fuel filters and oil coolers on the engine, transmission
and final drive housing may be modified.

[Lloyd]

Awesome!

[STeveD]

Certainly, oil starvation on the turbo Subarus must be worse than on the N/A's. Blowby gases can make oil more reluctant to drain into the block.

The other potential difference, Robin, is that Serge drives MIR. Turn 3 is nine seconds of G-loading. You don't find that at Shannonville, St. Eustache, DDT, etc.

Driving style has an effect, too. Someone who shifts earlier to rely on torque in the corners holds lower revs through the corner which could empty the oil pan 50% slower than someone who prefers high revs.

[Lloyd]

I'm lucky, turn 3 is the "correct" direction for my engine to turn (which points the wrong way, of course, but little victories)

[Serge]

well, depending on how we finalize the wording on the tire/fender rule (something we've been banging away on), i might get by next year with my old wheels, so i'll be on 205's

catch-can it is!

[Lloyd]

Yeah, I'm wondering how that would turn out.

I get how it might be hard to measure, but it changes things around somewhat...there are some winners and losers.

ie,

Winners: vehicles with no camber, ie stuff with live axles

Losers: cars with wide wheels (wheels pull the sidewall out beyond the tread face),

Not really the end of the world though

[valheru]

On my n/a build I will be running a 2 QT Accusump with the 35-40 PSI electric valve, this should keep any oil starvation issues at bay.

[Navigator]

Rear oil gallery plug near where the turbo would sit is the ideal location to T in the Accusump.

[valheru]

I've been recommended by Canton Racing, the makers of the Accusump, to go with the sandwichplate install, that way the oil going into the reservoir is always filtered.

Any special reason to go with the rear oil gallery plug?
