I have a common issue and I need some forum members with experience to chime in with their opinions.

I currently run a custom vmount setup but have struggled to find a position good enough for my oil cooler. Currently I have a ebay replica of the stock oil cooler after have my stock one sprung a leak.

I got a new setrab oil cooler 22" x 6" x 1.5" to junk the ebay **** and get better cooling, the present oil cooler sits behind the bumper and gets air from holes in the bumper pic below.

Last summer oil temps were a bit hot and did not drop with hwy driving so it's either shitty oil cooler *ebay* or shitty location oil getting enough air.

So I have a few choices
1. same location
2. Sandwich to rad lower part
3. Sandwich to rad upper part
4. Sandwich to lower part of intercooler





Below are pics of the oil cooler sandwich to rad and pics of space in between rad and intercooler.










Where do I mount my oil cooler for the best cooling and air flow?

 

I think you would be fine if you cut out the front rub-strip instead of trying to get the air through the holes in it.

On my Horizontal Mount IC I used the front rubstrip area as the entry for my IC duct and it had really good airflow.

Put some foam between the bumper and the oil cooler to fill the gap so all the air that goes through the rub-strip opening has to pass through the oil cooler.

 

Good point on the foam..... I personally like the holes.

I was thinking that the air was bouncing off the front completly and going over the bumper so I am not getting any air period creating some sort of negative pressure area.

While you may prefer the holes aesthetically you are right that they are causing most of the air flow to follow the body lines instead of entering the bumper there.
