oil cooler question?
I have a ATI Procharger D1 and intercooler setup on my mostly stock 87, after i installed this setup i had some cooling problems (not unexpected) i have a 3.25 core Griffin radiator coming for it, it was order August 30, so i hope it will be here in a couple of weeks.
my question is what kind of oil coolers are you guys running? i am leaning towards "earls" unit part # 41910aerl which is a 19 row plate type oil cooler which is 5 7/8 high X 2 inches deep X 13 inches wide to be used with there billet oil thermostat.
I plan to mount it in front of the air conditioner condenser and behind the intercooler. do you think this is enough cooler to keep the temps down to around 190 or so? i do not race or auto cross, it is just a street car. but it does get very hot here in Atlanta.

I am running the factory (oil heater) that came on my '87. My coolant temps typically run right at 195°F, with a corresponding oil temp of ~210°F. During the very hot summer days and back to back runs, I will see coolant temps of ~210°F and oil temps at 220-230°F. I am however running a bit far from stock components.
What is leading you to the conclusion that you "need" an aftermarket oil cooler? What coolant temps are you seeing? What oil temps?

I used to work for Valvoline where they made motor oil in Atlanta and i was always told by the chemists and QAC guys there that anything over 212 would cut the effective life in half, every time it got over 212, but this was before they had the syntheytics.
Coolant temps on a hot day will run 230 with the oil 15-20 higher.
Maybe the new Griffin Radator will help, but i am not counting on it alone to bring the oil temps down much.
Thanks for your input. Greg

If you are running the ATI IC or even the high boost IC from ATI, then it is blocking a portion of your radiator's air. The feed pipe comes up on the R side in front of the coolant area, and the discharge feeds downward through the 3.5" elbow, MAF meter, and into the 2.5 feed to the TB. All of this along with the IC endtanks serve to block precious air from the AC condensor and the radiator. I am not sure how much air you are pushing with your blower, but I would gues that your IATs are still in the 150-190°F range. Think of what happens when you start increasing airflow (and thus boost) and the IATs go to the 230°F range.
You need to look at an IC that does not block airflow to the radiator. I still run the factory fan behind a larger Griffin (manual, HD) radiator.
Hope this helps,

Aaron, the ATI intercooler does block air from the radiator, and like you said heat it up.
Even with a different intercooler, in front of the radiator is the logical place for it to be mounted.
do you have any experience with the ram air setups from Ecklers that replaces the front license plate, it looks like that would increase the air flow into the ("plenum Area") in the radiator cavity?
I do plan on running the factory fan behind the Griffin unit, the one i have coming they say is good for 600 HP and is the biggest they make that fits in the stock location, so i hope it will take care of the coolant temps.
I have thought about mounting the engine oil cooler horizontally with a scoop in a cut out in front of the left front wheel well at the bottom where the plastic shield is that keeps water and road debris, almost directly below the headlight, just to keep heated air away from the radiator.
I really do appreciate your help, i hate having to do things over because i made a wrong choice. Greg

Oil Cooler/Ram air duct
Hi All - I used the ram air duct that replaces the front license plate for additional cooling to the radiator chamber. This reduced the coolant temps by 15 -20 degrees in the summer. For this to work, a hole has to be cut in the plastic bumper and bulkhead on the front of the car behind the liscense plate area. I have a remote oil filter and oil cooler mounted in the left wheel well and under the car respectively. I am going to remount the oil cooler inside the radiator shroud, though. It doesn't work well where it is now. BTW - It really helps to turn off the AC on the hot days. (it sux, I Know) The coolant and oil temps are 20 degrees cooler with out the AC.
