how good is the STD b18c7 oil cooler?

i ran an oil cooler on my previous car, didnt get the chance to track it but on the highway i had to cover the oil cooler as the temp was getting pretty cool.

now thats in interesting implication

what happens there? If it is driven on the highway, it will cool down as there isnt much load on the motor when cruising...

i think engines need to be at operating temp, if it fails below that then the oil isnt doing its job of lubricating the internals...

someone can elaborate on that more

Yeh, mine seem ok. Don't think I have seen it less that 85 once its up to opperating temps.

You could set up a thermostat arrangement.

Its a good idea to let your engine warm up a little longer on cold start up too, as the Oil Cooler of course starts cooling once your driving an have air flow.

thanks mate, thats the answer i have been searching for from a million and 16 forums.. no one could tell me..

thanks man...

Im most likily getting temp guage to chep temp out .. scared now..:thumbsup:

I'm interested in this as well.

I'll be racing my car in motorkhana so it'll be going through short burtsts of hard driving and then it'll be sitting idle for a while and then turned off until my next run.

Do you guys think an oil cooler would be overkill for this type of driving?? Maybe a full sized alloy radiator would be a better option instead of the halfsize that comes with the car?? Seein as though the oil is cooled by the engine coolant??

Thanks

OK i have just read about MR spoon advising honda's dont need oil coolers on dc2r and ek9 la..

Mr spoon in a option mag said you are better off with no cooler as the honda designed engines can run at 140degrees and still redline with no issues..
the cooler is more trouble than its worth on a honda...

Dont kill the messenger.. this was gathered from honda tech

Yes, that info is correct.

I spoke to a reputable person that prepares race cars including hondas just recently. They did not even run a cooler in their DC2R and have had no problems.

Temps are apparently no probems, installing a cooler alone will cause pressure problems, especially in the top end of the engine where pressure is lowest. So yes, they will cause more harm then good and they are not needed.

I am taking my Cooler out this weekend. :thumbsup:

Sounds like i should stay away from oil coolers. !

what about a turbo B18C2????

i'd guess I'd need an oil cooler for that?

Well cause the oil is flowing through the turbo i guess you'd be exceding the expections of the standard cooling system.

I'd think you would have to upgrade for a turbo setup. Wait for someone else more knowledgeable to post tho. lol
