Pro Alloy Intercooler

[Kenobi]

We've just started trading with Pro-Alloy at work. I went down and got a tour of thier small yet interesting units.

Just about to launch a few things onto my website and came across this:-

This sits directly infront of the rad? Surely thats not good?

or am i missing something?

Hmm heat soak, then again I run a similar setup well an intercooler in the grill area and charge temps are good but because it blocks alot of the rad you need a decent rad fan as the OE fan is really at it's limits when the air flow is blocked at the front.

They use twin Spal fans these kits. i bet they are better than oe im just worried about the intercooler blocking the surface area of the rad.

Could the rad heat up charge temps being that close or is that not a possibility?

Yeah but the twin tiny spals are mounted on the front of the intercooler so they have to get through the intercooler to get to the rad I still don't think it will cool enough really. I think Adam L ran one and could prob provide a comment on effects better.


Yeah heat soak would be a concern.

I've got the same set up going on my 5, twin front fans and a uprated fan on the radiator. With using a seperate oil cooler the radiator copes fine with this set up. But i'm goint to cheat a bit as fitting water injection to come in above 18psi. :cool:

That sounds really good. Good luck with it fella.

dont the intercoolers let the air flow right through it any way?:confused:

Intercooler does allow the air to flow through, but in fitting this intercooler the radiator has to be fitted nearer to engine and firstly standard fan is to deep. Also if stood in traffic there is no air flow and so intercooler will become heat soaked. So twin fans keep good flow of air through it at stand still. Alot of hassle in fitting but to the unknowing you have big intercooler and standard looking front end. Bought mine second hand of a lad who ran at santa pod a couple of times and he said it works well with no issues.

Know Wayne & Alex there really well and do a lot of work with them. Quality is top notch

I have found with any kind of setup where you are introducing a restriction in flow – (ie another radiator or intercooler in front of the main rad) that it is worth spending some time on the following key areas as the speed of the cold air is definably effected going through the I/C even a very well flowing one

Gap between the pre rad (charge cooler) or intercooler and radiator is sealed to stop the air going out of the sides before entering the main rad as the air is now slowed down and the pressure of the air. You want to use a sponge or sealant that can cope with the heat but also if possible reduce heat transfer. Remember air will take the route of least resistance

Ducting / cowling to the i/c radiator (just look at how well this works on the oe rad setup!

Where the air goes after the rad – on the vag conversion I had to get the front of the bonnet louvered to help get the air out due to rad so close to engine and this got the temps down but about 8 deg on track – there is some science to air flow so be careful as sometime how you think air travels is very different in the real world

On the vx I fitted an override switch on the fans to help also control heat transfer to the pre rad (I have CC)

Hope this helps a little?
