  • vmount idea

    heres a crude idea i have for my vmount set up



    pink is the perminant frame

    black it the bolt on section so the tube front is removable

    gray is the intercooler and rad

    and thin black lines are the ducting i created a duct after the ic to hood and devided the duct to create sepreate feeds into the rad and ic

    I like it.

    I've been looking into a vmount setup so I can go with a bigger radiator and retain ac.

    There are a couple of drift cars on motoiq that have tubed radiator and core supports with vmount setups.

    I'll see if I can find them.

    I don't care about a sanctioning body, so no worries there.

      for drift where most of the airflow is created by a fan, this is OK

      for a road race car where the air coming in the front of the car is used for cooling the fins need to be aligned to the airflow, so you would (IMHO) need a rad and intercooler with fins aligned to be parallel with the ground (and therefore airflow) at installation.

        Well I have this interesting issue where my car runs cooler when sitting, but warm when cruising on the hwy. In fact, to keep temps down I turn on the puller fans on the hwy...

        I'm planning on going to an even bigger radiator, but don't have any extra room in the engine bay.

        And of course I'm adamant about keeping AC.

        I figured a v-mount would force the air through the rad and ic at speed... Maybe not as efficient as straight through, but on the other hand the radiator wouldn't be blocked by the intercooler.

        I guess my other option would be to go with an air to water intercooler, with the exchanger in the trunk area. Thats more moving parts and more stuff that can **** up tho.

        ok I was mistaken, there's a tube front area on both of these cars but neither is vmount:

          A bit of tilt on any heat exchanger is preferred as it stalls the air flow slightly to get a better heat transfer. A V-mount promotes this obviously if it is properly ducted. Drift cars used to run V-mounts half a decade ago. Now a days, they are just in oem locations. I couldn't tell ya if it was a JDM trend and turns out it doesn't work well, or if it was because a traditional setup worked just as well and had easier repairability during a front end crash.

            abit of tilt isn't really what's being discussed here though

              I'll do whichever promotes better cooling.

              I guess copying dai's setup would make the most sense.

              For some reason I thought a vmount would be more efficient. I didn't think about what tower posted as far as parallel flow.

              I guess this begs the question on how much tilt is optimal...

                In cooling you don't want to stall the flow of the fluid. Even if the air has less time to absorb heat, a better flow will always result in better cooling.

                Also bigger the difference in temperature, the faster the heat transfers. So if you warm the air around the heat exchanger, the difference wouldn't be as big.
