Capacity vs oil cooler

oil cooler.
the turbo by its self creates more capacity because of its oil lines, and an oil cooler also creates more capacity.

so with a bigger pan you get more capacity and marginally better cooling due to increased surface area.

with oil cooler you still get increased capacity plus you get a large increase in cooling due to sirface area. the cooler has 2 positives, the pan has 1.5
 
I agree. The size of the sump will only delay your time to peak normalized temps and perhaps buffer the transitions over your power output. It won't prevent it from reaching any given temp under sustained conditions.

If your rad is big enough to handle the cooling load of your planned performance output, I'd recommend an oil:coolant exchanger over an air:oil exchanger. The density and flow differential trump the temp differential by a good bit.
 
mmm good question. someone recedntly told me that the trans cooler is normally not under pressure. so i dont know if it would real with oil pressure ot not.
 
if you can do both, go for it; larger capacity oil pan and oil cooler will keep the temp. lower. The use of synthetic should also lower temps.

That is odd that you mentioned synthetic, the owner of Modular Power House has advised his turbo customers against synthetic oil saying it caused more blow by and smoking in turbo cars. I don't listen to much he says and plan on running AMSOIL anyway but just thought it was odd he would make a statement like that

That is odd. Synthetics here are highly recommended on here on forced induction vehicles as they handle heat much better than dino.
 
Looks like I will be doing both sorta, I'm going to do the cooler, but since the turbo will be mounted low getting them to drain above the oil level in the pan would be an issue, so there will be a catch can for the oil to drain from the turbo into and a pump to send it back to the pan. 6qt pan, 1qt catch, plus lines & turbos should have me just shy of 8qts
