[QUOTE=Irace86.2.0;3407695]Rallying is done on all surfaces including tarmac and dry dirt with no real difference to the bumpers, but generally mud isn’t an issue because the cars are racing staggered in a time trial, so there isn’t really a lot of traffic for mud clogging the bumpers.
Your point really doesn’t help the argument that maximal airflow is necessary. Apparently, according to you, rally cars need to avoid mud so much that they blocked off airflow, and yet, they are still able to successfully compete in rally racing with high horsepower motors and mud on the front with small openings. Those Group B cars were pushing 500hp. Just saying. Seems like all this fuss is for nothing, but maybe someone might want to fight for an extra 3-5 horsepower, or what type of losses are we really expecting from an oil cooler in front of an intercooler?
#1 i think you're overthinking this a bit.
#2 the picture you included has a top mount intercooler, which in all honesty server to suggest my original point and support my original theory. The top mount is in no way impeding air flow to a front-side mount oil cooler or the radiator in the middle.
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...
