Over-Cooling Solutions

[ResIpsa]

I was hoping to start a thread for all of us with oil coolers and live in colder climates. Who would ever think that over-cooling would be an issue...

Even with my Mocal thermostatic sandwich plate I am having trouble getting my oil temps to 180 degrees. This morning was especially cold (42 degrees) so I devised a simple, if not ugly, solution.

I took some painters tape and taped up the 2nd and 3rd grill. This worked well and it was much easier to get around 175 to 180 degrees on the way to work. I imagine i will have to tape up more of the front grill as it gets colder.

Keep in mind I copied ModShack's fang cold air intake. Those with the stock setting or any intake above the radiator might start choking the air intake to the motor.

you've just found One of the reasons the track cooler is not recommended for the street. More is not better (except under track conditions).

I noticed on a long road trip last weekend (60 degree temps) that even my standard sized cooler was running 175-180 degrees...

If you read about how the thermostatic plate works, you're pumping oil to the cooler all the time. It's the level of bypass that varies with the thermostat, but there is always bleed to the cooler. Make yourself a cover for a portion of the cooler to reduce it's efficiency.

(See page 5 for the final soluition to this issue)

Yeah, I am already devising a piece of sheet metal to place over the front of the oil cooler. I'll just remove it for track days.

And ModShack thanks for all the work that you do on this forum. Did you see my variation of the fang vent cold air intake?

What happened was that I forgot to order an extra set of flanges from aircraftspruce and needed to come up with a spur of the moment solution. I just massaged the 2.5 inch tubing and ran it straight into the air box.

That should work!

Thanks BTW...I saw your Mod.

I didn't pull those pass throughs out on mine because I lke to do mods that can be returned to stock with minimal time and effort. Regardless, the end results are the same. Hope it's working well for you!.....

Hey I learned something! I always assumed they shut it off completely.

+1 rep

EDIT: meh, you are repped-out for now, rep'd you yesterday =:O

What should I do?

You are in AZ....Dunno how cold it gets there, but you may find if the temps dip below 50 degrees you might have a hard time bringing the oil up to temperature particularly at speed on the highway for any length of time.(this is where the Thermostat is advantageous)

Had the oil cooler for w while now. Even if it is 70 degrees outside it takes the oil 30 minutes to reach 180 degrees. Generally the oil never gets above 170 degrees on my way to work in the mornings, and if it is really cool outside it will not pass 160 degrees.

I have the Stillen "race" oil cooler FYI.

I just want to know if shelling out $90 for the Mocal thermo plate will be a waste of $, if the temps wont change much or enough for it to be justified?

Yeah...The race cooler is too big....I'm sure the thermostat would help. I brought up these same concerns when Stillen announced the "Big" cooler with no upgrade on the plate...This is why they advertise it for Race applications. The cooler needs to be sized correctly....Even more important without thermostatic control....as you've found..

I am hoping since I live in Arizona, I wont have this issue. Having the Stillen Race oil cooler installed tomorrow.

hahahahahahahah this thread is great. it's just great in every way. thanks for the post op. I live in socal and am seeing 240+ degrees normally. I sit in traffic quite a bit and i can literally feel a butt dyno of -20 hp from the heatsoak. I can only wish it was that cold but i guess that's why the grass is always greener on the other side.

"Heatsoak" in the context of oil-temps has almost nothing to do with power-output.

Big oil cooler, Mocal thermostatic sandwich plate.

Outside Temp 50~55

Sixth gear on the highway 160 - 165. 170-175 fifth gear

I'd love to see a mod for controlling oil-cooler airflow...something like metal venetian blinds in front of the cooler with a control stick that you turn coming up through a hole into the engine bay. It would be a sweet way to avoid having to pull off the front fascia to adjust it.

To ResIpsa, Why don't you tape the cooler instead of the front grill. the car will love you, and it will look nicer with out it.

Just an idea.
