I know the standard car has an oil/water heat exchanger but I have no idea how efficient this is ?
I'm intending doing more track days with my car and was considering fitting an oil cooler. As modern synthetics will run happily at 120C+ I wondered if an additional cooler was really necessary ?
Anyone have any 'track day' temperatures for oil before and/or after fitting an oil cooler ?

thanks

Andy

 

I have never monitored oil temps, but as far as I am aware, they do run substantially hotter than the water, more than 120degC I think. The std one works well, coz its compact, apparently helps the warm up cycle of the engine, and once warmed, does help to cool the oil. I do have a funny feeling that a proper oil cooler would help the life of the oil, and possibly contribute towards a longer big end life. After all, if people put aftermarket oil coolers on N/A cars, then how important would they be on a high power turbo car?????
N/A cars dont really ever make any power, except in a few extreme cases. I think an oil cooler would be a wise investment, especially for those doing a lot of track days, or very hard driving.

 

Andy,

if you look on the GGR site (www.grahamgoode.com), there is a piccy and a bit of info on the remote cooler they sell.

From what I have seen on here, oil temps generally don't tend to be an issue unless you go for a FMIC. Obviously each car is different, so an oil temp gauge is the first step.

If you do decide to do it, I would talk to Think Automotive who are the UK importer for Mocal - their prices tend to be more competitive.

Thanks

hi andy

with my scoob, per the front mount i was getting 95+ water temps and after the intercooler i was getting 105+

i have never measured the oil temps but i thought they will be higher than the water temps by about 10-15%.


so i fitted an oil cooler.

again i was runing 1.3-1.4bar with a VF 23 most of the time anyway.

at the boost level you are runing, you would think that your oil temps will be higher. maybe?!


i hope this helps

You are getting water temps over 100degC ??? I think you have a serious problem there. Does your FMIC not let any air thorough it???

 

At my last track day i also got water temps of about 102 degrees.

Doesn't help that the radiator is the last thing to get any air.
Condensor and front mount both in front of water radiator.

Thanks guys. Sam, I should have bought that oil cooler from you earlier when you had your garage clear out ! too late now.

I'm fitting an oil temp gauge tomorrow, the sump is conveniently empty after its Knockhill spill !!!

What is the recommended maximum temp for Motul/Mobil 15/50 ??
My bike engined car runs up to 135C and it has a big cooler

cheers

Andy
