    which of these water to air intercooler would have the best cooling effect?

    they are all the same price (150 US),and its for the isuzu county. they all fit (although type 16 would be hardest as i would need to move pipework).


    type 8



    type 16



    type 20



    which would have the best cooling effect?

    Andy, type 8 and 20 would I reckon be the better units due to their contraflow characteristics, personally I'd pick type 8.

    I have a type 8, but with both endtanks pointing in the same direction. It does a fantastic job filling the box it came in, has done it for three years now.

    Assuming the cores are the same size, then boost pressure drop from inlet to outlet will be higher (worse) for type 20 - smaller cross section area and further distance to flow.

    The tanks on type 16 are a little better for flow than type 8, but if 8 is easier to fit, then that is what you should use.

    That's because of the miracle of actually applying the science of economics. The higher the Chinese standard of living gets, the cheaper they can make stuff and still make a bigger profit.

    How come no-one understands this?

    cheers, DL

    In order to get cooling you need to have the air in contact with the core. At least with air to air ICs the idea is to slow the air speed inside the IC down and have the air in contact with the core for a longer period, usually done by having wide short coolers in preference to narrow long ones. Without a core you would get the least pressure drop however not much cooling would occur. Pressure drop is important however temperature drop is the purpose of the cooler, your selection needs to be based on facts which are not that readily available.

    Suck it and see
