Help me cool my 20B
 
Ok, so the dilemma I am having is how and where to put my oil cooler with regards to cooling the car on the track. You can see where I have the intercooler mounted in relation to the radiator here (I am using an AFCO radiator standing straight up instead of the Fluidyne pictured, but same idea):

The problem as I see it is that my oil cooler is massive (Setrab, 18x11x2") and I'm concerned about getting enough airflow to all 3 coolers. In my NA application I had the oil cooler mounted right in front of the radiator.

My plan is to duct/close off the gap above the intercooler (aka. radiator panel), sides, and cut a wide additional opening in the front bumper above the main opening as shown by my MSPaint skills here:

Does anyone have any thoughts as to whether this will be sufficient? I'm not scared of hacking up any area of the car if it will help in the cooling process. All input welcomed!

Open up that air dam and use that area.

So this car is now for sale. Did the 20b ever run? Oil cooler installed?

I think I've actually decided to keep it and get it going (just closed the auction). I'm an irrational type of guy.

With any luck I should fire it up in the next week or so, but still not 100% sure what to do about potential cooling issues.

Ha! I knew you could'nt just sell that beast. You have got to get that thing on the track. :)
On the oil cooler, can it be put in horizontal. Basically build it into the floor pan, then duct air into and flow it under the car. You would only need say 1/2 the cooler exposed as big as it is. That would have been my plan but I have a first gen.
