    Looking at the type of coolers, it is nice for the cooler to have inlet and oulet, right next to each other as on the cheaper tube in fin coolers. However, there certainly are some efficiency drawbacks to that type of cooler.

    Does anyone have an idea as to what the difference is in oil temp?
    Also, would oil pressure be affected significantly?

    Most oils are designed to work optimally at 100C. Not sure I would want to try and keep it that cool.

    I think the RX cooler is going to be too big, unless you do some extensive bumper mods. I measured mine and the space will allow around an 7x20x3/4" cooler.

    So, I am guessing you are indicating a measurement at the oil plug, is that right?

    Madness seems to have the best value right now, seeing as how they have the nice adapter plate.

    The t-stat is the big question, lots of differing opinions. Guess it all depends on the climate where you are at.

    I have held off getting one cause winters around here are actually cold.........:D. But am getting real close to just going for it cause of the summer temps we get around here and the fact that the OEM oil cooler can leak into the coolant.

    Thanks for the article miniconcarne, a nice quick read.

    So, when you install an aftermarket cooler, what happens to the OEM heat exchanger thingie with coolant running through it? Is that disabled somehow? Edit: OK see it in the instructions, the OEM unit is 'replaced', so it is totally out of the system.

    Scottinbend, the RMW kit is very similar to the Madness, same plate, or at least similar, but I think the cooler itself is a little larger. Can't tell from the RMW site though, not much up there.

    Yes, I do believe that the RMW one is larger, with a price tag to match. Not sure how important the size is for a daily driver with a few track days thrown in.

    After a long drive or hard run, is it oil or coolant that continues to circulate for five minutes. If it is the oil or coolant, will adding the oil cooler in any way prevent the circulation of whatever fluid through the turbo after shut down?

    Very impressive

    But I am not going to go that far. I just want a decent oil cooler, with a thermostat and will need to be able to measure temp and pressure.

    I honestly do not yet see a turnkey system available with all of the features I want. Also hoping to avoid tube and fin designs.

    BTW Nitro, what kind of temp deltas were you able to measure after the installation of your crazy-cool system?

    I'm definitely looking into this as well - oil temps on track get up to 260-275 according to my (now tapped into the oil pan) stock VDO oil temp gauge :eek6:

    Typically I do a day or a weekend like this then change the oil pretty much immediately afterwards...

    If I get the Madness unit without a t-stat, does that mean I'll never get the oil up to operating temperature in the winter?

    I am coming to that very same conclusion. I may have to end up piecing it together as you have done. However, I don't think I will need nearly as many pieces.

    Also, no problem on the data, I am just trying to understand what to realistically expect.

    So true......

    Defending oil temp deltas, sounds like fun:crazy:

    Nitro, I think you misread Marc's post. He is concerned about getting up to temp in the winter withOUT a T-stat.

    Definitely true that you will bypass the oil cooler if you have a t-stat and it is too cool. This is exactly the desired operation.

    Also, as far as location, I am planning to mount the cooler right in front of the AC heat exchanger, just like what RMW, and Madness recommend. I expect to get enough flow there. So, is there any reason why you did not automatically select that location?

    Is 180 F high enough to burm out the impurities and allow the oil to thin to the level it needs to flow well?

    I'm curious Nitromini, where do you take the reading from, before or after the long route to the cooler as all that hose in the air stream will have a cooling effect as well.
