Just something I'm pondering. Probably won't work but thinkin about doesn't cost anything.
I'm considering an oil cooler for a new larger type IV (2270). I need to do rust repair in the hell hole this winter and I'm cosidering lowering the battery shelf and moving it toward the firewall. This could give me enough room to mount a cooler with a fan above the battery.
The positives 1)near cool air, 2)easy to plumb, 3)relatively inexpensive
The negatives 1)don't know if it will work 2)probably have to remove it to get to the battery PITA, 3)it will dump warm air on the battery.
Let me know what you think

Well, you could solve the battery problems by simply moving that to the front or rear trunk (which has already been done many times.)

Dumps hot air into the engine...very bad.
Done a lot of research...mesa with a fan..chuxters method (rocker vents), this and that...always come back to the front mounted cooler.
I think the front mount with a thermostat is the best method.

Yea, the front mounted cooler is the way to go.

this brings me to an interesting question.... on a car such as the 930 or a boxter, could you utilize the side vents for an oil cooler or is all that air for the rear brakes and engine?
and, could you use a 911 fendermounted oil cooler?

Nothing works "great" unless it is front mounted and has air passing thru it.
The last thing you want to do is pull heat off of oil cooler and dump it into the engine compartment to add more heat to the cooling air for the engine.
We have several people in this area running 2 oil coolers under the engine lid with multiple fans and they cant figure out why the car still gets hot..

Thanks for all the advice.
I'm convinced, not in the engine compartment.

If you were set on putting a cooler back there I would put it in the wheel-well. No reason it has to source or exhaust air to/from the engine compartment. But, like they've said: front is better. Too bad it's costly and a hassle.

Oil collers need AIR FLOW!!!
Kinda simple, really.

I did install a Setrab Oil Cooler in the location where the A/C compressor used to be, beside the battery tray. The Oil Cooler was fitted with a SPAL cooling fan (pull configuration) discharging downwards. Also installed a thermostat on the oil line before the Oil Cooler and oil adapter sandwich plate.
The Oil Cooler helps when the car is at a standstill or idling. Does not help much when the car is racing fast at the freeway

I got this today,, the best place for this to be mounted in near the engine compartment correct?
Brad Roberts
Jul 24 2003, 12:14 PM
I mount them up front... but most people are mounting them near the engine.
The whole idea is to have a bypass for the oil until it warms up. The oil coolers dont like to see 100lbs of oil pressure.
I cant prove to myself that one position is better than the other. Your still running the same amount of line to and from the cooler.

And did you know Don Haney (914 guy who used to live in Claremont)

To run an oil cooler up front, you need?
Sandwich adapter between the filter, oil cooler, lines, thermostat.
How much more oil do you need to put in? (ball park number)
Is that thing posted in the pic above a splitter that lets the oil bypass the cooler until the thermometer warms up enough to open and let the oil into the cooler?

Its a oil cooler thermostat, basically does what you said above. My cooler is mounted in the front.

or is it "fixed" ...

I don't think you can set the temp. for this to open but not sure, this one is designed to open at around 180 degrees.

I hope you are not running this thermostat on a 6 if its a 4 its OK but NOT for a 6.

No its a 4,, 76 2.0

Stratplayer, where and how much for the Mocal
PP's price seems a tad high.
StratPlayer
Jul 24 2003, 02:12 PM
Cheapest I could find was from Performance Products, $119.00 + shipping. I think Pelican wanted 124 for the same thing.

I mounted the thermo near the motor......why?
It's a bit easier on the oil pump.
With the thermo in the front, the oil pump has to push cold oil thru 15-20 feet of oil line to return it to the tank....with resultant higher back pressure.....vs 6-8 feet for the set-up near the engine.
I'm not a big fan of the Mocal thermo either. The pressure relief in the Troutman thermo saved my motor from my stupidity. The Mocal doesn't have this feature.

What's wrong with running this thermo on a -6?
MJHanna

:
http://www.rennsportsystems.com"A related issue is the oil thermostat. The Factory-style oil thermostat is a very special device. This regulates oil pressure, as well as oil temperature, to and from, the front auxiliary oil cooler. The pressure relief function of the Factory thermostat ensures that the inlet side of the oil pump is never starved due to the pressure drop in the long lines to the front cooler. Aftermarket oil thermostats such as the Mocal unit do not have this feature and you risk starving the engine of oil pressure during peak pressure demands.
We strongly recommend only using the Porsche thermostat or the Troutman thermostat since they both have the same internal architecture and use the same Behr element."

Brad,
I can take a picture and post it. Yes, I met Don Haney at Pelican Parts. Really cool guy, helped me at PP when I was buying parts there. Nice red 911 too. Have to attend one of their swapmeets one of these days.

I've seen one engine oil cooler I liked..... not the most aerodynamic solution... but cheaper and effective...
A local guy rigged a cooler in the engine bay. It clipped onto the inside of the engine lid for street purposes.. (yes, hot air in the intake)..
but the lines were a little longer than that.. when he showed up at Drivers ed. events, he had rigged a mount to screw in to the factory ski rack holes under the targa bar. The cooler popped out of the engine bay and attatched to this mount... Basically standing up above the roof. Full air flow.. not aerodynamic, but full air flow with short lines.

what if one were to do a 'corvair' style trunk lid. put louvers/scoops and mount the cooler back there. the air would have to exit somewhere.......(just thinking outloud)
brant
Jul 25 2003, 09:40 AM
lots of people do...
but full frontal air is still better.

They exit the air in between the rear tailights when the coolers are mounted in the trunk.

Where do I get the sandwich adapter ? how do I get air to the upfront cooler when there are no holes in my 74 SE Air Dam ? Can I use the coiled copper tubing from my bourbon still to cool the oil?

Maybe a stupid question, but I've been called stupid more than once, so it doesn't hurt so bad anymore. When woud you say you need to invest in one of these oil coolers? I figure in a stock 1.7 that its probably not worth the effort. When does it become worthwhile or perhaps necessary?

when your oil temp exceeds 230F in the service it is intended for.

Do I really need an extra cooler? At ~80mph on the Freeway, motor turns about 3200 rpm, and oil temp guage is about 3/4 way up.

Sadly, Don is no longer working at Pelican. I don't think he even has anything to do with the D&G swap meets any more.
