Over-Cooling Solutions

ResIpsa · 10-16-2009, 11:16 AM

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!.....

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.

Big oil cooler, Mocal thermostatic sandwich plate.

Outside Temp 50~55

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

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

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.

Valentino · 10-17-2009, 07:47 PM

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.

Let me re write it.

I was sleeping when i replied

Does it make since now?

ResIpsa · 10-18-2009, 02:27 PM

Do you know of any tape that can withstand the heat?

I guess I could use a roll of header wrap.

Valentino · 10-21-2009, 01:24 PM

I found a couple of tapes. Haven't try any of them, but they seem to withstand the heat.

Dontcha think taping is kinda ghetto? Just make a snap on metal shield that you can put on and off through the grill or the top.

Silicone tape used in powdercoating will take the heat though I'm reluctant to even mention it..
