i haven't had any problems with my oil or water temps even with an fmic until i installed my greddy turbo kit. at night my temps are fine but oil can go up to 220f. during the day water goes up to 200f but oil can reach 240f+ just cruising! and it doesn't help that the turbo is oil cooled only.

i have an extra oil cooler and planned to run a parallel set up but my concern is the drop in oil pressure. would an aftermarket oil pressure regulator be necessary? and would i have to use more oil with the added capacity of another oil cooler?

 

Well of course you will have to add more oil, you increased the capacity. No your oil pressure will not change.

I will be running rx8 style oil coolers here when I upgrade. Passenger side designated for turbo and driver side additional system cooler.

 

The stock OPR seems to work fine even with a dual, parallel set-up.
We run it in our 20B.
hIGGI also runs it in his car (and his friend's FC's).

that's good to hear. just this morning i saw the oil line from the front cover was partially pinched at the radiator support. and i just had some an lines made and they look like they would flow better. i'm going to see if that alone will help my temps but if not i'll go with the dual oil coolers.

 

i prefer serial setup with both thermostats working....but both works fine

 

serial setup?

 

i do too and it would be easier to plumb. but after searching it seemed like parallel was the way to go. higgi are you running a serial setup with no ill effects?

 

Parallel means much less pressure drop.

 

^^^^^^ Word ^^^^^^

After all I have read, and have been explained, paralell is the prefered method. Not as easy to plum, but more efficiant. Less drop in pressure, better overall cooling.

 

i run serial and i have no ill effects, however i have upgraded pressure regulator

 

I'm reading "serial" thinking "series" correct? We run two stock coolers parallel on the EProd FC. Our plumbing was made easier with a remote oil filter set-up. It had two in and two out so we used one in and the two out to the coolers. From there we just went to the front and back of the engine(we've gone external for the front to back transfer with a dry sump system). The biggest thing besides pressure drop with a series system is the difference between the air temp and oil temp on the second cooler isn't as great = less efficient cooling. It may or may not be a big deal on your set-up, definitely easier to do.

 

I'm curious. Where are you reading the oil temps from? Under the oil filter using an adapter? Or pan temperatures?

 

i'm getting my temps from an oil filter adapter.

 

Maxthe7man is the guy you want to talk to on this. He has done a lot of expirementation with the oiling system, and measured pressure drops accross various cooler configurations.

 

Does anyone have pictures of a dual cooler setup?

 

I don't think the pressure drop from parallel oil coolers should be an issue. If you look at the lubrication system schematic and specs in the FSM, you'll see there are actually two oil pressure regulators. One is between the pump and the oil cooler ("oil pressure control valve", 156psi rating) and the other is between the oil cooler and the oil filter ("oil pressure regulator valve", 71psi rating). I may be wrong here, but to me that 156psi rating implies the oil pump is capable of quite a bit more pressure than what you normally see on the gauge, and so the lower resistance of the parallel oil coolers result in less pressure at the engine. The only way to know for sure would be to measure the pressure in one or both of the oil cooler lines. Anyone keen?

 

I was going to try this a few nights ago but I need to ditch the ac first. Now I have another FC oil cooler that I was going to hook up. My question is did you relocate the stock oil cooler down further or did you just install the second one right on top of the stock one? Please fill me in.

 

i was thinking about putting a second one where the stock TMIC goes... i dont have a whole lot of room in the front with my big fmic and custom radiator, but my hood scoop is still functional... can anyone think of a reason why this wouldnt work?

It's a bad idea for the same reason why it's a bad idea to put an intercooler there...

 

Just some FYI that isn't all that relevant: I've a temperature gauge in the pan and one on the oil filter pedestal. On the whole, the factory oil cooler drops the temps b/t the pan and filter assy about 15 degrees F.

 

do it how the japanese do it. mount it right on the bumper.
