So I've been trying to install my new oil cooler setup for my Time Attack car, but I'm a little stumped.

I had everything hooked up and was trying to prime the lines, however when I was turning the car over I wasn't seeing any oil coming out of the oil cooler lines, or my turbo feed line which is off the stock oil sender location.

I have the mocal sandwich adapter, and I'm not sure which port should be going to the top part of my oil cooler, and which port should be coming from the bottom. I have my oil cooler mounted on the side.

Here's a couple of pictures maybe someone can help out?

 

Your style Mocal adapter has a thermostat on it, i think it opens at 180*F. So you wont see any flow till then.

Bingo. Great piece.

 

Yes that's correct, however I'm a little that I may or may not have the in and out ports installed correctly.

Since the unit is not closed before 180F it's 90% closed 10% open. Is there a correct way to hook the in and out ports up?

 

No, it doesn't matter which port of the adapter goes to which end of the cooler. Cooler is symmetrical. This assumes you are not going to remote filter and just going straight to cooler. Oil comes out of the oil pump into the center of the adapter and into the center of the filter and then out from the circumferential holes in the filter to the adapter outside.

 

Does it make a different if the cooler is mounted like the picture above on its side? I know the oil is under pressure, my only concern is that the oil would be coming into the bottom of the cooler instead of the top and having to work it's way up against gravity, causing more of a pressure drop.

Thanks for all the help guys

 

Top picture - Bottom Port = OUT to oil cooler
Top picture - Top Port = Bottom picture - Bottom Port = IN from oil cooler -> Filter

 

Doesn't matter in any way. Connect bottom or top of cooler to any port on the adapter. The oil pump makes over 80 psi, which is enough to push the oil anywhere you route it. Only issue is the size of lines, and pressure drop of the cooler. If you use -10 lines and any normal sized cooler, you won't have a problem. Like I mentioned, the only time you have to be careful about routing is when you use a remote filter, and then you want to make certain that the pump output goes into the middle of the remote filter. For just routing a sandwich adapter to a cooler, there is no difference which way you route it. If you want to reduce the pressure drop by 1/10 of a psi, you can route oil outlet from the block to the top of the cooler and the outlet of the cooler at the bottom to the return side, but it really doesn't matter. The gravity difference over 12" in height from top to bottom of cooler is totally irrelevant compared to the pump pressure.

 

That makes sense. I wound up going with -8AN lines, and noticed a small drop in pressure. I may increase the size of the lines to -10AN. I thought when I was first designing the setup that a smaller line would help reduce the amount of pressure drop, but it seems that it's the opposite.
