i've got an oil cooler kit ready to install and a tranny cooler kit on its way. my problem is choosing which way to face the cores to get the best flow/cooling effect. my car is an auto r33 gtst.
i've really only got 3 options which ive drawn up to stop any confusion of what i'm talking about (sorry about my dodgyness, its 3:20am).
these are my thoughts on each option. i dont know how much pressure is inside the trans system so bear with me.
#1 will make the oil flow too quickly out of the core because of gravity + pressure, plus i dont think the trans oil will flow through the entire 19rows, it may mainly use the first 10 because of the low pressure in the system.
#2 might be ok as the oil will spend more time in the cooler as well as utilise the entire core. but i also think that the trans cooler will drop in pressure as its trying to push the oil out against gravity.
#3 im not too fond of. pretty much the same reason as #1.
i've seen installs using all 3 directions and im really not sure which one is the best, or even if my ideas are right, thats why ive come to you guys
the engine oil cooler should be fine to use #2 with as even on idle it has around 30psi of pressure, so it will utilise the entire core as well as have enough psi to get the oil flowing, whereas the transmission cooler has less pressure so im not too sure about it.
this probably isnt a huge deal to alot of you guys but its been playing in my mind for a few hrs.
