911 dual oil filter set up

911 tweaks · 04-24-2006, 12:14 PM

#1: has anyone seen or if familar with putting a twin (qty. 2) engine oil filtration set up for the sc? Will this impede oil flow a/o pressure? Does this make sense to do? Maybe an adapter that attaches to the oil tank or plumb out of traditional oil filter mounting location and go to a 2 filter set up...that maybe someone has already fabed? Any help here from you guys?

#2: Also, does the oil pressure build up systems offered that you establish BEFORE you start the engine help/worth the cost? maybe just install a fuel pump shut off switch which would be used when 1st starting the engine for the day...crank the engine for 30seconds? stop cranking...turn on the fuel pump and let system prime...start the engine? Just thinking here...any input and any additional info can be provided.
I am in the tweeking mode again!!! maybe leave well enough alone and get a life!

Why? Are you having problems with oil contamination?

I've seen these discussed in other forums, and while in theory it makes sense, the cost and complexity (ie more stuff to break) doesn't seem to be worth it. 30 seconds is a long time to crank an engine!

Are you tweeking or tweaking? Big difference, but it almost sounds more like the former than the latter.

thx for the quick response!! the car is not having any issues since it is a resto project in my shop. Just wondering if such exists since car will get new elephant finned lines; wide mouth front wheelwell cooler; new engine mounted oil coler; modified oil tank with fabspeed bottom baffel...basically I am paranoid of killing new/used engine that will be installed since orig. engine punched a hole thru side of case and I will replace all oil contacting things. #2 30 sec might be tooo much but any comments on presure build up before starting?

I'm running this setup, though this is not my car:

I truly believe it is overkill, but liked the idea. Should the motor blowup, I will save the cooler and thermostat. At that point, what's the difference, though??

The difference between tweaking and tweeking is not subtle, as I understand. I don't have direct experience with the latter, though I laughed pretty damned hard at the comment from Thom!

any concern about all of that plumbing in the wheelwell i.e. if a tire lets go a/o all of the road sh%^t they pick up and throw around?
any info on a 2 filter set up that would go in the engine bay?

Porsche oil cooling lines are always in the wheel well,even from the factory. I guess the risk is worth the reward. Do your homework by searching here in the archives.

Here's the accompanying oil console, same car by www.patrickmotorsports.com - check the gallery of photos.

That sounds like the filters are in parallel, since it talks about perfect for high viscosity oils?

I don't have that issue.

now we are getting warmer...any "PORSCHE" world input guys? I dont know where to put/plumb such a device and I would really appreciate any help fellow pelicans can chime in here with. Thanks again everyone for your help so far!!

DW SD- can you please explain more your response to the cb perf part that was posted by Jason @ pelican and what you mean by you dont have that issue? Thx alot

I have one of the Peterson filters as well, just before the oil cooler, on my 914-6. I don't know that its necessary, but it provides an easily inspectable screen, which is the primary reason I have it, the "no need to clean the cooler" after an implode the second (I mean, if your engine explodes, the need to clean a cooler is the least of your worries). Race teams use them as its not usually possible to clean a cooler at the track, but you can change a blown engine.

Used ones are 35 bucks on ebay, they have 12 an ends, both female, and some have a 10 an port for a gauge, mine is just capped.

Take a look at the dual filters used on the factory Rallye cars... 1. lots and lots of crud and nasty rocks thrown into the rear wheel well. 2. Very high engine loads. 3. Very important to win those races. 4. Must never never lose the engine ...

- What?? Can't find any dual filter setups there? Maybe, that means...

The provided link says perfect for high viscosity oils and a few other comments for which, I can only conclude that the dual filters are run in parallel, which would reduce head (similar to back-pressure) on the oil system.

As you know, actual oil Viscosity varies with temperature.

I live in a warm climate and don't have a problem with oil being too viscous. I do run 20W - 50, which is relatively high, but not given my average temperature here (I live near San Diego, CA). Coldest day this year was about 45 degrees and I didn't run my car. Average temp when I drive is 70.

Randy,
The factory has different criteria for setting up their cars than we do, as you know. Economy is just one major point of difference between myself and the factory. (IE...I can't (or don't want to) afford to replace an engine, and don't want to consider throwing my cooler away). In race applications, Longevity can be measured in hours, depending upon the race and being lightweight supercedes other things.

As I said, maybe overkill, but I'd bet that many of us are guilty of overkill or being overly conservative with these cars.

I don't get the impression you are being critical. However, I spent a few hundred dollars to try to ensure my engine gets clean oil. I spent far more to ensure it gets cooled oil.

Did I waste $$ and installation time? Quite possibly.

I am sorry Doug & Randy. I am not too sift with the computer...can you please show me the link to click on to see the factory/rallye info you are referring to showing the dual oil filter set up. thanks again

I think you've already seen it.

911 tweaks · 04-24-2006, 04:45 PM

yes I have seen this product. Is this what you all recommend to use for the additional oil filters? I could of sworn that I have seen a set-up porsche uses or maybe it was a custom job or maybe I was dreaming of perfectly clean oil flowing through the perfectly who knows how dirty used engine...at least what ever is going to flow loose from the innereds of the used engine it will be caught in the very efficient/redundant filtration system.

randywebb · 04-24-2006, 05:12 PM

I was joking -- or trying to. I do not think dual filters are needed. I can't imagine what you'd be doing to need them - sand rail maybe - esp. on fine powdery sand in Arabia.

"I'd bet that many of us are guilty of overkill..."
- Surely no one on this bbs would ever be guilty of overkill!

911 tweaks · 04-24-2006, 05:20 PM

just my way of trying to keep the oil as clean as possible pumpin' through the sc of unknown internal condition and to best position it for longevity...I can see the responses on longevity i.e. dont use it...this car will NOT be a garage queen...it will be USED but not ABUSED!!

No worries, I just might have solved yet another problem that didn't exist!!
