heat exchanger

[Guest]

can one of these nice shiney alliminium radiators from trademe be used as a heat exchanger for the water to air setup...using a rs legacy pump??

[DRFVDR]

yup

could use any radiator u want

connecting pipe work will be only issue

will doing this on my RX when i install the water to air intercooler in it

[Guest]

oh sweet....that saves me from buying one of the frozen boost heat exchangers and getting ripped off on shipping.

I asked this same Q in tardme...and some guy who seemed pretty know it all'ish said you couldn't. But I'll give it ago anyway. Thanks

[DRFVDR]

that is why the CLUBSUB forums are so much betterer

we spin a different sort of bullsh*t

mostly we know wot we doin

[Guest BLST!C]

Or at least we sound like we do.

Just make sure that whatever you use has a bleed point at the top of it.

[wildturkey]

yeah nice little mod that one. I've heard (duno if true or not) that running a bigger radiator at the front increases the overall efficiency of the water to air system. Let us know how u go with it

Buy another heat exchanger from a wreck, take your existing one and that one to a radiator shop and ask them to cut off the endtanks of one of them and integrate the two.

It's been done before and MRT used to offer this as an upgrade and thats the method they used for a larger heat exchanger.

I was wondering Can 2 oil coolers be used aswell??...Also If I do end up using a bigger heat exchanger would a hi flow pump like a bosch pump be required or will I get away with using my original one. Looking at a heat exchanger about the size of MRT's ones.

[Guest]

be wary of the speed with which your coolant flows through your larger radiator. more flow does not equal higher efficency.

i would recommend doing a google search on some of the science involved in the heat transfer aspect of water to air systems. If you increase the flow velocity or flow volume, and your coolant passes too quickly through your larger radiator, you will get less temp drop, irrespective of the larger size. I agree with increasing the size of your radiator as an improvement, but you need to match, radiator size and pump flow carefully.

It's exactly the same as the old "running no thermostat in your engine to cure over heating" BS. it acts as a flow reducer to extend the period of time the coolant spends in the radiator being cooled.

IF YOU WERE USING THE STANDARD PUMP THEN IT WILL BE FINE.... I BET YOU WONT EVEN TELL THE DIFFERENCE THO.... IT MAY DROP INTAKE TEMP BY 2-3 DEGREES......

Agreed, my post was in reference to 1992-RS's question about a hi-flow pump. I believe the factory set up when running correctly is quite adequate. I have heard benefits from fitting a storage tank between the radiator and the intercooler however.

This gives a larger storage capacity of cold water to provide to the cooler, before water from the radiator starts to cycle back through. If ya know what i mean.

[DRFVDR]

That would work pretty well as a larger capacity will always be better,and then you could include a container to hold ice/dry ice for xtra cooling if needed

so after looking for something to suit my needs in New Zealand Iv decided to go with the frozen boost heat exchanger from the US...its not a bad price $373 NZD and thats including freight. They have changed freight companys and the freight is cheaper than before so ill be sure to buy one of the following

-------------------------------------------------------------------------------

the first dimensions are: (inches)

26x7x2

second:

24x12x1

all im left with is a decision...Im leaning toward the 2nd one what do you guys rekon?
