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!

 

I don't think it is such a good idea to cut out the energy-absorbing portion of your bumper. You may want to check the racing forum to get ideas for better options. In general, you want about a 4:1 ratio between the heat exchanger core area and the inlet cross-sectional area.

 

The bumper is a fiberglass shell with a support beam behind it. I can modify the beam so that it still has some impact value, so that's not too much of a concern.

I'll post in the racing section, good idea!

 

I have a radiator, 2 oil coolers and an intercooler
Heres what i cut:
