Two oil coolers?
 

Anyone know if our pump can handle an extra oil cooler. Was thinking about adding a second.

Yes I ran two 34row coolers... it's over kill! My oil temps never truly got into operating temps unless it was 100* outside and I was beating on the car hard! Two smaller ones would do fine but two large 34 row coolers is too much capacity. The pump can handle it but it doesn't do you any good

So basically stayed at thermostat open temps Like 180ish or so?

Where did you have them placed?

In front of the radiator and behind my intercooler. They were centered in the opening

You may be able for find pressure drop (AKA ΔP (delta P) and DP) figures for the coolers.

If the coolers are in series, add the DPs to get total drop across the coolers. If total DP will leave you with enough system pressure, then all you have to worry about is too much cooling with two coolers.

If in parallel, use the parallel resistors formula (if DPs are the same, total will be half of the individual DPs for the coolers). Total will be less than the least restrictive (lowest DP) cooler, so, if either of the coolers will pass enough oil, adding the other will only decrease total cooler DP.

Just driving I'm around 160-180. Track I'm 230-260 so you see the need. Beauty is I can just reach down and throw a plate in front of one since all my hood latch stuff in the front is all removed.

I may add a second cooler since I still hit 240-250 degrees on the track with a 34-row. It's not a high priority, but on the TODO list nevertheless...

Well ive vented the nose for the CAI and air will reach the top of the radiator now and i got a CSF triple pass on the way so we'll see. If i cant stay sub 240 im adding a second cooler.

I would throw a 24 row in line. Mine was two 34 rows in line. The only thing I think I could have done was thrown a block off plate in front of one to help bring the temps up.

My 48 is like a 34 so ill keep that in mind.

So, im about do get this going....

Im looking at 2x 19 row setrabs that im going to hang sideways and hovering the fender wells vertically....

The venting - I bought a second 2015 nose used without the drls for a steal... i figure, the drl holes should supply sufficient venting along with some naca vents for the brakes... Im also adding 1 spal pusher fan per side. They will be controlled thermostatically via relays and inline thermo sensors @ 200 degrees. The Exhaust will go straight out the fender well via a grill that ill fab and house the suspended coolers with pp plastic as a form of shroud.

Plumbing - I plan to run it in series with a thermostatic bypass somewhere in the middle so its running on 1 until 180 degrees. Im planning on -10 an for the system since the coolers arent huge.

The oil pump will get swapped for another oem with a billet gear to handle the forced induction and extra oil capacity

Right now, i have a 34 row on a mocal thermo plate and -8an plumbing and no fan... in Denver summers, its just not keeping up with me, especially in the mountains... track is showing 250 degrees ( not over, since i back it off and go for a cool down lap when i see that.

The overall IATs are insane. I plan to drop in turbos this spring (should have been this month) and i want to clear up the radiator/ FMIC. This should do the trick along with a vented hood as a planned purchase for the spring.

Before doing all that, I'd explore ventilation to move hot air out and/or upgrade to a 72 row.

When I had the 2015 nismo bumper on engine coolant temps peaked at 237F and the oil was in limp mode territory in summer weather on the track. That bumper is just too restrictive IMO for track duty. You would need to make many holes in it for it to function.

Im assuming that you are responding to my post....

I will be evacuating the hot air directly out the fender wells as not to contaminate intake air and add to IATs...

I am trying to maintain an oem look to the car while solving the temp issues. Id prefer not to start adding on aftermarket body panels..

If it gets to that, ill end up upgrading the rad and possibly add a vented hood.

Vented hood. :tup: I put TrackSpec cutouts in mine. :tup:
