has anyone put dual oil coolers in thier car?

im thinking of changing front bumpers and going with dual coolers off to the sides.

I have a FMIC, AC, and thicker core Koyo radiator- cooler oil is essential to a rotary motor so dual coolers out in front all on thier own would not only cool the oil better, but I would imagine it would allow a little more airflow to the rest of the components.



I also know the stock oil cooler is pretty efficient so im wondering if any of this is even worth the hassle?

there's a giant right up on teamfc3s I'll pull it for u

here yah go buddy

as long as the stock cooler gets good air flow i think its fine.

cool write up, but no before and after comparisons to see if all that work is worth while or not

it has that bad=ass cool factor though x10

overkill for a street car imho rob..

It will definetly work, my only "issue" with that setup, is that the oil coolers only fit without the hard plastic bumper.

That car is not on the road yet. Just like the coolers, its getting a ton of other customs things done to it.

It will be running one of the higher end Motec units, so I think some good oil temp numbers will be available once all is sorted out.

PWR now makes a drop in replacement that is really nice.

the stock fc oil cooler is a beast, tons of other cars use the fc cooler as an upgrade unit. i think the biggest thing fc guys skimp on is ducting, all the FD guys spend tons of time on ducting of the FMIC and Rad and it makes HUGE and NOTICEABLE differences i say just get some sheetmetal and rivets and do some real ducting work and youll be fine.

Run Dual FC coolers and be done with ! ! !

I don't think you need to upgrade your oil cooler unless you are running 400+ HP.



FWIW that dual oil cooler setup on teamfc3s.org looks cool. But would be crap on the race track. A small bump and you would have destroyed one and causes a oil leak and loss of oil. Last thing I want to do is not finish a race because I got tapped or someone tapped me right where the oil cooler was.

I also think it's overkill, a little extra airflow to the motor would suffice: I.E. vents but I'm into that ****.

everyone throws vents and ductwork around, but I cant recall one person actually doing it.



when you look under there aint a whole lot you can do as far as venting goes

I know the thread is getting a little old, but I would like to be more talk about oil coolers (dual vs single) and what is possible with venting and ducting.

best (simplest) is to add a little flap under the cooler (like an 80's gm car) so the oil cooler air comes from under the car.



the other things you can do are to seal off the radiator opening, so the air that goes in the nose HAS to go thru the coolers, we did this with cardboard and duct tape on the racecar back in the day



you can also seal the oil cooler to the stuff around it.

Or you can get a lip spoiler that has an opening in the bottom and duct it to the rad/oil cooler area. I did that with my Corksport "Odura" (?) lip.

any back to back testing with no other changes?

do you happen to have a oil temp gauge?

I have VDO oil temp taken in the pan and water temp taken at the water pump, but cooling isn't an issue on the street so back to back testing would be useless. I did it so that I'd have more airflow at the track and I can run as hard as I want as long as I want with no cooling issues, but I've got not much more than stock power. I still could do with getting the temps down a bit (they get up to the 230 range), but they're not at the concern levels. Another way to get more airflow is to run a vented hood like they do on the C6R Corvette LeMans racers. This can help by lowering the pressure in the engine compartment and giving the air somewhere to go, which will help drive more airflow through the coolers. Also, sealing up any way for the air to go around the rad will help with water cooling, and you could try ducting around the oil cooler.



Many road racers use two stock FC coolers plumbed in parallel in the mouth, usually one in front of the other, which isn't ideal, but it's so oversized that it's more than adequite.
