I always thought of doing this mod too. But my question isnt necessarily a question of WHERE, as your looking to get that filled. My question is, is it effective?
I am setting my suspension up for AutoX, my engine is already Stage4+++++, and I think in addition to that since there will be alot of rhomping on the car at somewhat low speeds a more effective oil cooling system is in order.
I was thinking of something along the lines of an off the shelf transmission fluid cooler from vato-zone or advance to keep things simple. like a 12x6" cooler mounted in front of the radiators.
Now really, is extra oil cooling necessary in my application? Im setting up for AutoX as mentioned, most my driving is 40miles/day highway commute in Louisiana where the lowest avg. weather is like 30F and highest is 110F.
So a very important application question im thinking about is if this cooler is all mounted up and seeing 30F (and the 70MPH wind chill!) will the oil be inefficiently cold?
Should the system be bypassed in winters?
What are yalls thoughts? Be sure to answer the OPs question too if you can as my question is so a hi-jack (but doesnt deserve its own thread as its along the lines of OP)
