A member on club was/is selling their ride on ebay, and they had this pic of a very nicely installed front-mounted oil cooler. Not sure if it's full flow or not.

Here's the listing (no affiliation):

near the tranny, but, unlike the one above(post #10) I didn't mount it parallel to the trunk, it's at an angle to let more oil stay in the cooler and to let more air above it... the back bracket is lower... I'll try to remember to snap some pics

I am getting clooser to installing my oil cooler. I am now gathering my last few parts and am wondering if those with a fan on the cooler are using a tempature switch to turn the fan on? And what switch is being used?
I don't want to put a switch on the dash or even worry about turning the fan on. So a switch that is controlled by the oil temp is what I am looking for.
The pelican article list several switched, but after aquick web search the switched no longer seem to be avaliable.
thanks

I went switched, not thermostat. 1 less thing to fail... where I am only in the coldest weather would you want it turned off... so it just stays on... I put the switch in the engine bay. if the car is running, the fan is on... I didn't want it to try and cool oil that is already too hot. and a thermostat is one more thing to fail.

Elephant sells an adjustable fan switch (160 to 200 F). In use here on a 3.2. This car a factory -6 that I didn't want to hack up. This is just a street car so cooling requirements are not so high. Seems to do well. Temp measurements using an infrared thermometer are erratic, but there seems to be 20F difference in vs out.

For Papa Smurf, we have the cooler mounted to the floor in the front trunk, with the air coming in the front bumper, through the shroud, through the cooler.

Pros and cons -

Pro - the air is heated AFTER it is leaving the front compartment space, so the shroud, and hence the front trunk, do not get hot.

Con - In effect, as in any 914 GT cooling set up, you are forcing hot air under the front of the car creating lift - exactly opposite of what you want in a race car. I have really started to notice the lack of downforce I have. For a street car, no big deal, but for a race car....not good.

I am considering moving this cooler set up to Huey (street car) so the front trunk area does not get so hot. For Papa Smurf, I am thinking of putting a normal front mounted cooler, and ducting into the wheel wells (similar to how a 911 cooling works)

this set up works really well. Engine is a high compression 2.2 with 200+/- hp, redlines at 7300 rpm. Both Nadine and I have driven it on the hottest days at the track, back to back runs, and temp never got above 200.

EDIT #1: Added picture and filter part number

EDIT #2: This location works great for a four cylinder car. However, putting even the biggest cooler (12" x 11" Setrab for example) under the trunk will work for around town when running a 3.0 six, but not so much at the track.

I've used the Derale Atomic Cool on 2 different application mounted next to the transmission with excellent results. There was at least a 20 deg drop in oil temperature if not more. What's nice is that the kit comes with a temperature switch.

I use the relay to enable the fan off of the + side of the coil. Main power for the fan comes direct from the battery with a waterproof fuse holder.

The sandwich adapter has a simple bimetallic spring that allows oil to flow once it reaches 180F. I also modified the oil filter mount to eliminate the spring loaded ball (so oil doesn't bypass through it due to the increased pressure drop of the oil cooler) and use a Baldwin B228 filter with an internal relief. It is the same length as stock, but a smaller diameter to clear the engine bar. (Save your breath, yes the filter has less area than the factory filter. It is more than sufficient for regular oil changes (IMG:style_emoticons/default/KMA.gif))

Oil cooler is installed. I mounted it under the rear trunk, ran the cooler lines through the engine compartment, added a thermostaticly controlled fan.
I am able to keep my oil temps down around 180 to 190 with the fan running. I pulled the fan fuse and noticed the temps climb into the 210 range. I am pleased with the outcome.

My next part of the project will be to add a small LED in the oil temp gauge to indicate when the fan is on. But it may be a while....

Heres a hardline setup I made for a 912E... The customer wanted the stock front mount 911 oil cooler setup. Used a Mocal sandwich thermostat.

I dont like the idea of dumping hot air from tehoil cooler back in to the engine bay, that adds hot air to the cooling system and air intake. the idea is to dump the heat from the oil outside of the engine bay. Not put it back into the engine.
