Top mounted Oil Cooler Problems

[Flash]

Has any one fitted an after market oil cooler to the factory intercooler location on top off the engine & had oil pressure problems?

I have heard all different opinions & under stand there is two oil pump sizes & heat soak problems etc etc.

I would like to here from some one who has actually done this with the standard oil pump & if they have had any oil pressure Problems?

This is a race car with modifed sump & remote filter etc & is not used on the road.

Rowan (5UBZRO) has his oil cooler mounted up there on his race car - drop him a PM and see what he says about it. As far as I know he hasnt had any issues...

555sti's was an off the shelf oil filter relocation kit that just happened to be long enough to plumb up on top. xecuta may have more info on it

seen a few track / rally cars with them mounted on top??? they wouldnt do it if it was a bad idea?

The only bad thing I could think of is maybe the oil may drain out of the cooler everytime the engine turns off, but maybe not as you would probably have to let air in to the system to let it drain out (i.e pulling the oil filter off)

what about installing a check valve (one way valve)

Just wondering what the problem with that would be?

only problem i could think of would be filling up with oil & checking it? have to measure & making a new mark on the dip stick or something wouldn't ya?

After speaking to the boys at Possums I have decided to give it a go. They have had a few cars in their work shop with this mod & they are fine.

Also their gold rush car is still running the smaller std pump with twin oil coolers in both front sides with only -8 lines & 80 psi of pressure.

So I am going to give it a go!

I have now made the Aluminium mount brace & an Aluminium air deflector under the bonnet scoop. The cooler is mounted with the fittings on the top so it won't drain out.

I have also made the cooler easy to remove with the lines on or off so I can move it out off the way to get to stuff & also drain the oil out off it.
