Mounting Oil Cooler Between Fmic & Radiator

[tricstar]

ok, there might be nothing in it, but I would appreciate any input,, thanks

I'm about to mount a oil cooler and custom a/c condenser and panel between the fmic and rad they will basiclly get half the space each.....

my question is......would there be any benefit mounting the oil cooler on the passenger side, to keep the heat from it away from the cool side of the intercooler ?? or does the volume of air going through there mean it's not really an issue ??

not chasing 110% but just want the setup to be efficient..

thoughts ??, experiences ??

I opting for that spot as apposed to in the guard because I don't think it gets enough flow behind the indicator..

bit of extra info : its a big single putting close to 800hp, sees the track so oil cooler will get hot..

ideally mount the oil cooler with its own clear airflow.

putting an obstruction infront or behind it is going to affect the flow of air through it, i.e. air is more likely to change direction and go around your oil cooler than through it, because of the increased restriction.

if you must put it infront of the intercooler, you should check the temperature of the air after its gone through a fully loaded oil cooler, then compare it versus the temperature of the compressed charge passing through the intercooler at that point. what you dont want is the temperature of the air after the oil cooler to be above that of your intake charge... you'll end up adding heat to your intake charge (the opposite of what you want).

if you are confident this is not the case, then the best place to put it is on the hot side of the intercooler. more chance of the heated air after the oil cooler to still be below the intake charge temp. if you put it on the cold side, you run the risk of heating the intake charge.

if youre running 800 hp and seeing the track, i think you can afford to remove the indicator when running the engine at full load.

think about it. an 800hp build is worth a lot of money and effort. dont skimp on your cooling setup. if your indicator is in the way, look at getting some proper ducting made up to take air from the opening you do have and shrouding your oil cooler.

Mine is mounted on the passenger side just infront of the radiator (no aircon) seems to do its job fine there.

your right in regards to not skimping on the cooling setup, thats why I'm asking the questions.. ideally I would like the oil cooler to have its own air flow like behind the indicator, but I have another R33 GTR which came with an oil cooler behind the indicator, and when I'd go to the track I'd take the indicator out, after a couple of brisk laps it would be at 110 or over on a cool night ( maybe the cooler is just old and dirty,? ) it also has the air direction shroud....

so maybe a new more efficient one will be fine in that spot,?? it would also keep the heat out of the engine bay, which would have to be a good thing.. is that the general consensus ??

Titan-- I really do want to have a/c

mine is mounted on the driver side. Didnt really see an increase in engine temp in that location

My lack of AC isnt because of the oil cooler its to do with the turbo setup.

still lots of room for the AC there.

it can be quite a science to determine the best place to mount a cooler for airflow

ducting helps if it is set up correctly.

ideally you want the ducting to capture air, to create a high pressure zone infront of the radiator you're trying to cool. the ducting needs to be sealed around the radiator, or the air will prefer to bypass the high restriction zone by escaping out any unsealed areas.

the next important thing is to have a good airflow exit from the rear of the radiator. ideally you want to also duct the exit to a low pressure zone (i believe there are some low pressure zones around the wheel wells). if not, then if you have decent front aero, you can also vent to the low pressure area under the car.

cheers

I'm gonna put it behind the indicator with some directional ducting and cut out the front inner guard, and put some sort of lovue setup to stop road grim being flicked onto the cooler..

thanks for your help
