I’m building a MNR VORTX with a tuned duratec, hopefully I’ll have around 230ish bhp, and it’ll be a road legal track day car.
My question is, do I need an oil cooler? It’s got a wet raceline sump, and the old fiesta st150 oil filter mount heat exchanger thingy. Running this requires fitting pipes and teeing into the coolant circuit which is a pain. Alternatively, I can buy and fit an oil cooler. Is it worth going the oil cooler route, am I likely to see high oil temps on track without one? I’ve been looking at the thermostatic oil coolers, as I understand the oil can run too cool with a non thermostatic one. I have a coolex water radiator with the fan on the engine side, so an oil cooler would have to go on the front of my rad. Would a 16 row one be about right?

I've got one on mine as when it was hot the oil pressure dropped so fitted an oil cooler, but it turned out to be a bad earth. Is it required - not for me as I only drive it on the road. On the track maybe?
