External oil cooler

I checked in the knowledge base and found nothing. At Samba there was a lot of conflicting info so what are you guys who live in hot spots running and where is it mounted.
Moving to teh hi desert in Oregon this week and 100F in Jul, AUg, and Sept is not unusual.
Thanks

Ralph, there is a thread somewhere about me installing one behind the drivers side wheel. Summit Racing has the sandwich plate adapter or go between the engine and the oil filter and you simply run lines from that location straight over to the oil cooler.

I personally wouldn't waste time or money on the electric thermostat switch for the fan and would elect to have it run all the time instead. The oil only goes through a tiny bit until the sandwich plate mechanical thermostat reached 170 and opened up all the way to let oil really flow through the cooler.

Derale is the name of the unit and it will fit in the location you want. It is the 16 pass thin compact unit there is only one like this. Don't buy the 8 pass unit as it is not going to do the job you want it to and also isn't any cheaper. Once you get the unit you will be able to pretty easily figure out how to install it. You want to set it up so that the fan is "pulling" air through the cooler as this is suppose to be more efficient.

How come nobody likes the front of the car with one or two saab or rx7
(short and wide) coolers mounted in direct airflow.
1. it would be at or below sump level so no dry line worries
2. add volume to your oil supply
3. we all know that psi is equal throughout system
???????
Why do what everyone else does?

That's a great thought Bruce!!! I'm with you on that one!

I put my cooler in the front under the battery box. added a channel along the drivers side to carry the lines to the front. On warm days the car would run very hot up to 230. Now on 100 plus days or stop and go it says in the 190 to 210 range.

I've got mine in the driver's side rear wheel well. Oil filter is also mounted hear. Units are easy to get to and with about 6 ft. of braided lines. Oil temp doesn't get near 210 F. I rarely get to 210 on my 18 mile freeway runs to work.

BRuce and Larry:
My car had a cooler way up front and since IMs have a frame the lines ran thru it--HOWEVER the engine builder did not like that little oil pump pushing the oil the length of the car. OTOH, since it was all hooked up it would have been nice to try tho and see if it made a difference.
I will try mounting one near the back.
THanks for all your thoughts guys.

John :
WHat brand cooler did you get? Did it include the sandwich plate between the engine and the oil filter. I am having a hard time visualizing all of this. Does the oil go to the cooler before returning to the oil filter?
Give me yoiur thoughts on this set up. It has tubular lines which I have heard are not the preferred. I realize this set-up has no fan but since I am only looking for a 15F drop in temp I thoiught this might suffice.

15 degrees of drop is going to need a fan, I doubt you will get the CFM you need without the fan

Thanks Stevan. I will get one with a fan. On your long thread that I read, Eddie said the cooler that fit over the filter was spozed to reduce temps by 12%. That would be all that is needed but it appears you do not agree and of course those kinds of claims come thru marketing not engineering.

Mine an RX7 unit mounted in the front...

Brian:
I saw your set-up in an earlier thread. My car had a cooler in front but my engine builder would not warranty the motor if it had to push oil all aboiut 15 ft, so I took it out.
I found a local tech here in Bend and told him that the heat was causing my car to run up to 230 on warm---90F+ days. He said that is normal for Bend and not to stress over it. I am bringing it to him for a driveablity check and have him go after the temps with a lazer thermo.
I like your frugal attitude but I do not have your skills...welding etc.

Stevan:
I found the Devan cooler in my Summit cataloque but the sandwich plate was specific to FOrd or Chevy. What did you use.

I just told them that it was on a VW engine and they seemed to know exactly what I needed. And the one they sent me threaded right on where the filter threaded on, then I bought a filter that was a little shorter to make it easy to take on and off without hitting the fresh air tube that goes to the heater box.

Some people have special braided stainless hoses made, but used the rubber high temp hoses that came with the oil cooler and it worked just fine.

Make sure it is the Derale thinline unit, 16 pass and it will tuck up in behind the wheel well perfectly. I ran 4k miles with this set up and never had a single problem with it.

Steven:
I will call them on Monday. Thanks for your follow-up on this thread.

Summit is open 24/7. I ordered the Derale fan kit. The sandwich adapter was the lower one listed in teh catalogue---for FOrd and \Chrysler and "most imports" It certainly was a lot simpler than buying a new oil pump, cooler kit, connecting and mounting hardware that was the option from a VW on line shop.
I will do a benchmark test as soon as it is installed, say THursday or Friday of next week.
RIght now 90F outside crusing at 3500rpm brings me up to 230-240F. I was told by local guy with lotsa experience that around here this is not unusual but that is little comfort to me. We shall see. I am hoping for nothing over 210F as some of you have reported.

The old filter style you used may be to long after you put in the sandwich adapter, just take the old filter to the local parts store and tell them you want the shortest version of that filter. It will make taking the filter off easier then it was before you put the sandwich filter in. Buy the best quality full flow filter they have and you will have no problem at all.

If this isn't enough then will have someone put on a 356 fan pulley to get that fan moving faster and you should be cool enough at that point.

Ralph:
I have a 72 pass Mesa oil cooler (I think it was an Empi part) and a standard external oil filter stand. Braided line goes from the oil pump to the filter, then to the cooler and back to the case. Simple set up. I built plates with bolts welded through them for installation in the engine compartment and plates with stand-off or risers on the wheel well side to allow some airflow across the back-side of the cooler. No fan or thermostat. My engine temp rarely gets above 210 F. I'll snap some pictures if you want.

My engine's a 911 so pushing the oil up to the front is standard fare. I think it also depends on the size of line....the bigger the line the less it has to push. Within reason...

There was very little skills involved...the braided stainless cut with a fine tooth hacksaw, the threaded connectors go on with a couple of wrenches, the welded parts I took to a shop as I dodn't want them to leak, the alum shroud is just sheet alum found at the dump (cut and paste link below), etc...
