I have an Escort Mk2 with a 360bhp yb on it, and was thinking of preparing it for track days, Does anybody know what size of oil cooler would suit a yb at that stage .

I was going for the largest found and then use an oilstat sandwich plate but due to limited space maybe i will look for something that is just a bit more than enough.


Thanks Guys

A few years ago i wanted oil cooling too, but really didnt want to go changing everything and spending loads of money.
So what did i do?
I found a rather heavy duty looking heat sink, not literally heavy, but could do a good job of sapping some heat away. It was about 5or6" square, with 2to3" tall fins standing off it, and i set about bolting it to the bottom of my sump, using computer heatsink compound that sets like cement to make the perfect join. The heatsink needed a little work on the flat face to make it fit my sump nice and snug, and the sump had a captive nut welded in place to take the underhanging heatsink. When it was bolted on some fuel tank sealant was used on the captive nut to stop it leaking. Jobs a good'n! It noticably took longer to warm up, and the fans almost never cut in. Its important i think, to have the veins of the heatsink lengthways with the car to accept the high speed air underneath and make a good heat exchange. Just... God help the cat if ever you run one over, it'll come out the other side like mince meat.

Be aware though, if your gonna do this, you mustnt take liberties with speed bumps. It wouldve been better im sure if i used 3 bolts to hold it on. I think it took a knock underneath with my spirited driving and started to leak a drip or two here and there. I reckon this could be a half decent race mod if its done professionally, cos it was noticable i tell ye, even on the standard pants temp guage.
