    I'm thinking about using a stock depth cast aluminum pan on a 2004R. I don't want a deep pan because of clearance under the car. Hot Rod did a side by side test and found the aluminum pan dropped the fluid temps about 10 degrees. Has anyone here used one or have a comment?

    Yeah, it's a good idea, and they seal better as well.

    What Larry said.

    I fitted a deeper pan and it's still not the lowest thing under the car. Adds fluid capacity and it all helps cooling. Oh and it no longer leaks! I also junked the supplied paper gasket for a Moroso one.

    The B&M pan I used also has a temp gauge port.

    Cheers

    I’ve got a larger cast alum pan than stock on my 2004R but it isn’t too deep or low hanging. I don’t have any good pics of it but it’s been reliable.

    Thanks - sounds like the way to go!

    I have a pan from Hughes Performance.

    Ground clearance is about 41/2" w/ empty car. I guess that once I have headers installed, they will have less ground clearance.
    Don't know about the temperature, as I have no temp. gauge installed and on top have a separate oil cooler.
    Hope that helps.

    That does hang down a bit low I’m not sure if I would like that. I will have to check the height of my pan.

    will come up a bit once I have the aluminum heads underneath the hood :)

    I would worry about a big bump cracking the aluminum, then the fluid is
    soon gone. Steel more likely just gets bent. I spend my money on super
    duty (cooler) 4 row radiators. good luck, Bruce Roe

    Bruce - which cooler did you go with?

    Lately have had to order my big 4 row radiators as near custom
    brass and copper, no aluminum here as I could not do any work
    on one. The internal coolant to trans fluid cooler is all I use. An
    external trans cooler is another way to increase the total capacity,
    but at the the cost of temperature controls, possible rubber hoses
    leaking, more stuff I manage to do without. Sometimes a modest
    front radiator fan has been used, primarily to help when sitting
    idling (esp with air cond), or to continue to aid cool down after
    shut down. Not for on road use. good luck, Bruce Roe
