Some friends tell me that fitting an oil cooler will result in some loss of oil pressure. Is this true?

If it is, how much oil pressure will I lose? Is it significant and can it lead to problems?

Sorry if this topic has been discussed before. Any help/advice/comments would be appreciated.

Thank you.

 

Yes, it will result in a loss of oil pressure but probably not enough to worry about.

I just checked Acuraautomotiveparts.org and apparently the Type R and GSR oil pumps are the same....and the Type R has an oil cooler. It's not some crazy oil cooler, but it's there, so basically I wouldn't worry about it.

 

It's true that whenever you lengthen the path of oil flow, you will lose some pressure, this is true with everything else as well. You'll get more pressure loss using a cold air intake vs. a ram air, you'll get more pressure loss using a large radiator vs. a small one, and you'll get more pressure loss running a large front mount intercooler vs. running a small one in the engine bay. It's all a matter of how much pressure loss are you willing to take, and is the tradeoff for another benefit (in this case, reduced oil temperature) worth it.

 

Has anyone measured oil pressure before and after fitting an oil cooler? I know it depends on many factors including condition of main bearings, size of cooler, etc. but it would be good to know.

 

I don't think it would really be all that notable unless it was a particularly large oil cooler. All you would need on a Honda motor is a small cooler anyways, so I wouldn't worry about it at all.

don't forget that the gsr also has a oil cooler. it's not a air cooled type but instead uses the coolant from the engine to cool it down a bit.

 

Hmm, sorry for not including this earlier, but I am talking about a 1.8 litre engine with a 1.0 Bar turbo, with a conservative size intercooler about 20 x 25 cm.

After reading about oil coking in a turbo, I've had a phobia about oil temperatures.
