W2A Intercooler

Has anyone had any experience with the PWR tubular water-to-air intercoolers?

I've been looking at the capa one. You can fit it where the battery lives. The only issue you get with w2a coolers no matter what sort, is heat soak. But this can be overcome with a 10litre+ water tank in the circuit

According to the Repco performance catalogue, the PWR units are half the cost or less of the CAPA one, IIRC a kit with a 6" dia by 8" length unit rated at 600hp is $1,695 or so. These can mount closer to the throttle body too.

EBsixOnBoost on the forums, runs a W2A cooler.. ditched the Air to Air one for it. He's dipping into the mid - low 11's now. Stock motor apart from turbo cam.

Yeah the capa one is well overpriced, but there is a mob that sell the exact same item on ebay for a lot less. Advantages of a W2A over A2A is less pressure drop, and if there is enough water in the system temperatures are kept a lot lower then with a front mount a2a

But theres also methods of keeping cool a FMIC to, kits from Iceman and the like which give water sprays, hydrogen cooling around it, butane cooling even. Gets to the point where your cooler gets frost on it.

Laminge is running one on his ts from memory

Ive sold a Few of these Kits whilst working at the Parts Shop .. The Price of the PWR ones compared to the CAPA ones is Sound .. as the Quality , Extensive Testing , and Size of the Cooler are Second to None ..

There shorter than your normal Intercooler piping too so the Lag from turbo setups its cut down a bit..

was talking to a fellow yesterday about this exact topic
he is on the forum somewhere cant remember his exact nick on the forum LOL

but he is a cooling system specialist
and said a W2A is better for superchargers over turbos as SC produce less heat and can handle the amount of heat being exchanged
as the surface areas are different inside the cooler

where as A2A has a larger surface area to soak the heat out of the charge air etc and are more effective for turbocharged applications etc etc

ill direct him to this thread later when i see him online

The same ones capa import and sell are sold through a mob in Brisbane on ebay for around $500. Equiped with a large air cond condenser to cool the water back down and a 10 litre water tank, these are a much better option over frount mount air to air. This sort of setup will keep your temps lower and only have a 0.5psi drop

Well i'm no longer called a cooling systems specialist, more a consultant now :P

As for what i used to specialise is, its more to do with the radiator and engine cooling side of things... But i have learnt a great deal over the years in regards to forced induction and the strain it put on the engine cooling system.

Water to Air requires a good sized cooling core in order to transfer the heat, without it cooling enough, then it becomes pretty redundant and you will have power loss... BUT Water to Air can produce really good HP when used in the right way... I'd recommend it in area's that can get rather hot... in cooler places, an Air to Air would suffice... but these are still determined by the function you are putting the car through... Qty's of turbo's and sizes still play a large part in this... 2 turbo's can cause a problem with plumbing and put to much strain on a Water to Air system.
