I wanted to know if anyone has seen the effects that a Oil cooler has on oil pressure.... I think this time around, I am going to need one to drive around town.. but i need my oil pressure!! Thanks
Anyone monitor before/after Oil Pressue with a Oil Cooler??

X2. I have a line on an aircraft/AN line one I might install. It gets HOTT in this 'hurr desert!
I'm putting my oil cooler next week. Right now, my oil pressure with a 98 cooler bolt with NO stock cooler but just an air to air cooler, I get 2.3.2.6 bar at 1000rpms. So around 33 psi or so, full engine temp. Not sure on oil temp yet, I will find out soon though.
So, when I do connect my oil cooler I'll let you know. They say the main difference is that it takes longer to gain pressure when you first start up.

I have noticed no (-) change of oil pressure on mk3's and mk4's when I have installed oil relocation kits with air-air oil coolers.
One word ACCUSUMP!!!! Never spin a rod from lack of oil again!!!!

I'm not worried about lack of oil... just trying to figure out a way to keep temps as low as possible and oil pressure up.

With MK4's as you know they cool oil with hot coolant.I don't think its a good idea. As for street use oil coolers do a great job of keeping oil temps down as long as they are placed in a spot where they will get sufficent air flow. Not stuck behind a huge 4-5 inch intercooler that will rob it from cool air.
And BTW most of a engine/turbo wearing times are on start up, now a pre-lubing system will cut bearing wear down alot. As I said Accsump. It's insurance I think anybody with a high horsepower engine should not be without.

I am asking these questions .. so i can see if i can make a 1/2 filled motor work on the street... where oil temp is the only issue.

The rule of thumb is 10psi of oil pressure per 1000 rpm....just fyi.

Ive heard that too, but it doesnt sound right. I had 10 psi at idle, in an sr20det, and I was told by several people this was ok.

1/2 filled should not be a problem, being only 1/2 filled your still running some coolant............right??
Size and placement of the cooler is the key.........if you get a large enough one, one to run a small fan to help always have a consistent amount or air flow running through it (like at a long stop light or just on a oil temp that you feel comfortable with) you will be fine.

It was partially filled block per emails I exchanged with Ryan about a year or so ago.

1/2 filled is a known problem with oil temp. With a half filled block, there is no coolant running through the bottom of the block. i dont have a "stock" oil cooler and I have not had good luck with the sandwich adapters...
I would run a oil cooler... but with a high perfomance motor... as you should know oil pressure is key. I may install it to see what pressure is.. if its to low.. i will try something else.
