Thread: Radiator & pump suggestions for WTA intercooler

Just like this one:

It may be worth double checking this, I have one of these and there is a clearly visible plug in the header tubes to pass refrigerant back and forth, through fewer tubes at each pass. Still better than a R12 one though.

Yes, I noticed while you were typing that's at least a dual pass. I had a dead one for a while (holed core) but the scrap dealer got it.

Whether it's worth trying to convert one to single pass is another question. Long drill down each tank, weld in some fittings etc.

This may or may not help, but maybe try and talk to some of the L67 guys (Holden Commodore Supercharged V6 + USA vehicles) they have been running w2a setups for a while. I'm currently running a MACE Engineering w2a in my supercharged commodore with about 15psi. It's a very basic heat exchange which works great, but will have to grab the brand on the pump. I've listed a few websites that explain and may help about intercoolers and pumps.

I relise these are a different engine and differernt scenario, but the information on heat exchanges and pumps should be helpful. I will list some more as I remember then.

Gotta remember, that unlike a petrol, a diesel is on boost ALOT of the time, so really need to overdo the WTA setup, mine is rated for 800HP on a petrol engine

True, I can understand the demand these engine have compared to a petrol engine are alot greater right off the mark. I will say though I am impressed with the heat it does take out of the supercharged air on my setup.

Also has anyone thought about a combination of both a2a and w2a? It might be overkill but was just interested/wondering.

Edit: sorry probably getting away from topic there

I was given a verry simple and effective system its a small car ally rad with about 30mm outlets and the WTA intercooler all i need is the hoses and a pump it also come with a wiring harness and presure switch in the I/C plenium to switch the pump on .
My plan is to mount the rad on the underside of the RHS fender as far foward as possable and fit a air scoop at the front of the guard and to fit a shroud on the underside with a thermo fan to also help draw air at slow speeds .
Its all a pipe dream at the moment as im still colecting bits but it should not be long now before i start to play with it i now have a turbo and manifold set up to try and with some of the great tech info ive read from this section i think i may well be on a winner i hope

Is that a real rating or an "ebay rating"?
The WTA intercooler I've got (garage ornament, 3 years and counting) can be found on ebay with power ratings from 300-1000hp.

As far as I'm concerned hp ratings on intercoolers are BS. There are two main questions:
Can it pass the airflow you need without a serious restriction yes/no?
Can it cool enough for the boost pressures you intend to run yes/no?

There's another important question too: Can it keep water out of your intake? I still need to pressure-test my one.

No, some of us don't purchase rubbish

So you own personal experiences with intercooling is?.....oh that's right, sitting in the shed

Oh, I've stoled Vern's puta
