Oil cooling on a 16v track car

Just gauging peoples thoughts on oil coolage when using a valver on the track. I suspect that it would be a good idea to fit a oil cooler rad, but would it be better to retain the heat exhanger plate, or remove that completely, and just have a sandwich plate and remote rad?

Anyone?

Also, can anyone recommend a good donnor for a remote oil cooler rad? Mk1 Golf?

Experiment and see.
I tried both setups without any dramas.

I think my problem is I try to get everything right in my head first, and don't think about experimenting. I'll see what happens with the standard setup first

I use a mk1 take off had some hoses made up to run an audi diesel oil cooler under the battery in the old IC cowling. Seems to work very well. Oh I did this so i could keep the water cooler as well and run the full size G60 oil filter. Water cooler gives you a cooling option when sitting in traffic on hot hot days.

any ideas how much energy the standard heat exchanger can transfer?
What do VW/audi use on the TT 225 type engines?, do they bother with oil coolers? Most VW's seem to use one kind of heat exchanger or another, can you get a bigger one to fit a KR/9A/PG block?
It might be just as good to simply fit a twin fan larger rad from a passat/VR6 or air con car.
I'm assuming the block is cooled mainly by the water jacket and providing the water temp can be kept down the oil temp will reduce proportionately?
For extra protection, fully synthetic oil should cope with maintaining lubrication at higher temps/revs.

I've used the take off plate off the old Volvo 740 turbo and cut the metal lines to suit,Lancia delta int. is a very good rad. which i now have but very fragile as it's all aluminium so go carefully when tightening the large end nuts.The volvo or saab 9000 turbo cooler rads. are also good.
I reckon that the e36 Bmw m3's oil cooler rad. has to be the ultimate in design but they never 'appear' on the 'used' market..

Dave and Graham have knocked up a new extension piece that allows you to retain the existing factory water sandwich plate as well as bolt on a mocal of similar.

For pure track use a stand alone mocal has to be better as you will always have airflow over it, there is a chance running the water cooler on track will just assist the heat cycle between oil and water temps, raising the overall engine temp in the long run.
