Which oil cooler mounting location is best?

[Payne]

Looks like I have 4 options for air to oil cooler mounting-

1) between the radiator and the frame
2) behind the frame behind the radiator
3) at an angle in the space between the A-Arms
4) horizontally in the HE space where the HE mounts on the 300s

I'll be running a 8x11x1.5" Oil Cooler. The big question is how effective will it be behind the radiator. My instinct is that at 60+ MPH, really the only speeds that I'll need the oil cooler to do any work, I'll get plenty of air through the radiator, so I won't see a huge difference over ambient going through the oil cooler.

My instinct it option #1, so that I can guarantee that the air gets through the oil cooler without a lot of ducting. I worry that with 2,3, and 4, air will just move around the oil cooler and lose effectiveness.

Thoughts?

Thanks,
Jason

Option #1 - use the radiator mounting tabs to mount the oil cooler between the frame and the radiator. Will be tight but fit okay:


Option #2 - mount behind the frame. Probably build an AL shroud coming off the back of the A-Arm mounts to ensure air gets through the cooler.


Option #3 - on the 45, pulling air from beneath the car. I worry about how to shroud this to get effective airflow:


Option #4 - the stock HE location. I worry about damaging the cooler, and getting good flow of air to it

If you mount it behind the radiator I'd put a fan on it. The aftercooler radiators used on the GM engines didn't do that good up there cooling the air to water intercooler but would probably be ok for a oil cooler.

Another option is besides the engine. Tom at unique fab makes that mount
