When you ask "what type of losses are we really expecting from an oil cooler in front of an intercooler?"
Well.... that depends on ambient temp/humidity/drive duration/driving style. Lets say I want to aggressively cruise the blue ridge parkway in the NC mountains with friends for 5 hours straight in the summer.. There's ZERO chance of "overcooling" so WTF should I cover half my intercooler OR should I look at another option to KEEP the best airflow to the radiator AND intercooler (also like many have said, im not sure I buy that theory on the grounds that in 99% of driving conditions thats just a non-factor)... basically why the same car can be sold for winter use in Fargo ND or Miami...

#1: My point is the OP is overthinking this a bit.
#2: That 2007 WRC rally car has a FMIC with a top mount air intake, but that doesn’t really matter because the point of the picture was to illustrate that the bumper doesn’t get peppered with mud like the sides that are behind the wheels. I could have used an Evo or something too where the FMIC is plainly visible, low and exposed.
The comment about overcooling was missed on you. The point wasn’t to say overcooling is a reason to put the oil cooler in front of the intercooler; it was to suggest that there is enough cooling available with the given area, so much so, that restricted air flow was sometimes preferable.
Remove overcooling from the vocabulary because I already conceded that idea had little merit. What loses to the cooling effect of the intercooler, or what losses to horsepower could be seen from putting an oil cooler in front of the intercooler, because the premise of this thread is that dirty (warmed) air will leave the oil cooler and hit the intercooler, apparently, significantly reducing the effectiveness of the intercooler?
Here is a HKS side mount intercooler. It requires longer oil lines, and it doesn’t get the airflow that a front mount oil cooler would get. It also blocks a good place for brake ducting, but it could be used. Some would say, “That’s...not great airflow.” All I’m trying to say is people shouldn’t create a bigger problem trying to fix a perceived problem that is more significant subjectively than it is objectively and that could in fact be worse.
