bullet proof lube system

[tyrannix]

this is my plan.... but it just occured to me, this might be overkill, because the CA already has a built-in oil cooler...

for high boost application 18+ psi

remote dual oil filter system (one normal for down to 20 micron, then another filter for 1 to 20 micron) with a temp switch for an air/fluid oil cooler, then a 1.5 quart oil accumulator .. to allow a lower level of oil in the pan = increased power from less drag on the crank?

is this overkill? ... planning on getting into auto-x with this car ...

and then if i use this setup, i should be able to cut the oil cooler out of the engine coolant loop, to help keep engine temp down (using a stock radiator, and except when the system was dry, i never saw the temp get above half on the meter, actually just below half.. it goes there and stays there.

i wouldnt recommend running less oil in the pan, you might starve the motor turning sharp on the autox course,

[fanta]

I'd go with an oil cooler and an upgraded rad.

[Not_a_sr]

stock temp gauge is junk! you can be well overheated and still show middle on the gauge. i dont think my stock gauge really goes above the middle till 130deg C

also cheap upgrade DSM radiator with dual, dual speed fans. its huge and i actually only run the smaller fan on the lowest setting and it keeps the car cool. i was in a drift event in 90deg weather for hours and never had to turn the car off to cool down.

[biosehnsucht]

my fans turn on at 198F right now adn its still dead center in the gauge, stock gauge is crap.

one of these days I want to find a way to hax it up so that it can be useful..

Thats what I did in my DSM. Worked like a charm.

(yes, I did edit the quote a little :P )

oil starvation wont happen because of the accumulator (it stores and automatically plumbs in whatever amount when oil press drops) i was going to go with a 1.5 quart model and run .75 quarts low in the pan ... with all those hoses and stuff (remote filters, oil cooler and then the accumulator) id think it would be somewhere around 7 quarts in the system total

forgot to mention using elec fans too... is the water temp sensor really that bad? i ran dual fans on it for about 2 months before i stripped the car

and ive started a little creative airflow project in the engine bay

but back to the subject... is all of this overkill, or would just an upgraded radiator handle the oil temp anyway.... i mean the engine has a built-in fluid-fluid oil cooler... and i never had a problem, but i never ran the car hard for more than about 20 mins at a time

does anyone have a reference on the efficiency of the stock CA oil cooler(s) (there appear to be different models of the oil cooler that ive seen) ?

the temp sensor is great, its the gauge that is the problem, if you hook a consult or techtom up to a KA or SR(or my CA using a SR ECU) you can see the temp, its really accurate. the stock temp gauge however is horrible, once it reaches the H, you motor is already toasted. nissan did this because normal consumers dont want to see the gauge moving around, that would worry them.

I can confirm this for the KA24 as well. Best sensor that will ever crap out on you when you need it. haha, seriously, it is designed well and accurately measures the temp within about 2 degress, if I remember the test readings I got from my last NA build. I am told by my old tuners shop they are exactly the same type of sensor as the CA too...

The real question is how well does the CA18DET ECU read the sensor?

[tyrannix]

well, i just did it, bought all the components for the "bullet proof oil system" .. oil cooler, dual filter remote mount system, and oil accumulator, with a bunch of hose until i build braided stainless for them too

ill post results on cumulative oil temps and pressures during cornering once i have them installed and working (and my engine installed )

-CJ

edit> and ill look into a water temp gauge if my powerfc tells me things that the cluster gauge isnt telling me... good call

[CA19DET]

just weld a baffle into the pan so that the pickyup is always fed oil from the accumulator to the small box that you create around the oil-pick-up... i like the sound of your set-up... very interested, if you can remove windage and keep a adequate amount of oil around the pick-up, and lower temps - you would be golden.

[float_6969]

If you're worried about windage, just lower it down a couple of quarts! I'll bet you'd be suprised how long that motor will run with the oil pump sucking air!

[tyrannix]

if plumbed correctly, the accumulator is only activated when pressure drops, then it plumbs oil directly into the pressurized system... i guess that means it goes after the pickup..... i havnt really figured where it will go yet, wont be able to do that until i have all the parts sitting in front of me

it might do just like you were saying, and shoot it down into the oil pan, but that wouldnt be a guarantee that it will start circulating... as in a hard auto-x corner or something, where a direct plumbed line would go in tandem with the oil pump...

again.. i need to see all my new toys in front of me before i figure out how they will all work together

[tyrannix]

holy crap

i received all the hayden stuff today...the oil cooler is rediculously huge, and the filters... the normal filter is as big as commercial ones can get.. it looks about 4 inches in diameter ... then the bypass filter is just as big around, but twice as tall

ill post up pics soon, this kit is HOSS.. the whole thing will probably give me another 50% oil capacity (this is without the accumulator, havnt received that yet)

ill be able to put a bowl of salad under the pan when i change my oil....

i showed some of the guys at my shop today... they laughed.... saying the oil will be cleaner coming out then when it went in

[Dattebayo]

the oil will be cleaner coming out then when it went in

I could be missing something, but isnt that the point of all this?

[ca18detdrift]

I know heat kills the engine/components, and its always better to have a higher cooling capacity than a stock one. But...do you honestly need all that cooling capacity for auto X? I mean most of the auto X runs over here in las vegas are about 40 sec - 70 sec per run, then there is about a 20 min down time waiting in line to run again. (then about 2 hours of working the track lol)

[CA19DET]

preventative maintenance is key with a turbo motor

[tyrannix]

yeah, the cooler is only part of the kit (and its got a thermal switch, so only when it needs it) its mostly for teh remote mounted dual filter systemthe normal filter gets everything down to 20 microns, like a normal system, then the bypass filter strains out 20 micron down to 1 micron sized particles... when combined with the oil accumulator, this system will keep the engine flowing with cool oil under almost any conditions (even sideways or whatever, the accumulator plumbs in up to 1.5 quarts into the pressurized side when there is a loss of oil pressure

this is one of the things that will keep the engine running a long time (if everything else goes as planned)
