Air to air intercooler in D pillar ideas please!

[goffoz]

This is a project I'm working on this week also.
So far this little scoop,

plus adding some engine compartment tin and splash shields. and a big bash plate, has reduced my engine temps by about 10deg....don't have a IAT temp sensor yet
No pics of the tin yet, still working on it. I will seal, and duct the drivers D pillar down to the max low pressure...just forward of the tailpipe.
..opening will be a greater volume than the scoop and face rearward.should create a large low pressure
We'll see

....for lower road speeds there will be a fan on the IC

Thats a good looking scoop. What is a good low pressure area? I thought I would use the D pillar and funnel/duct it to the I/C, where it is then doghoused to the I/C. If I understand; then it's from here the air that exits through the I/C needs to be duct to a low pressure area"?"

.just forward of the tailpipe. ..theory at this point...we'll see Very Happy
when I get it ducted I'll throw my pocket anemometer in there and go for a drive

so thats in the area where the PS pump is with a water boxer?

I have a very simple solution to increase airflow through a pillar mounted intercooler; simply mount the intercooler, seal around it, mount a tapered shroud over it and connect your fresh air intake tube to it, that will draw fresh air through the intercooler, cooling it. Simple.

Hi,
here u can see my solution in a 16 Syncro with AAZ and watercooled turbo.

Feel free to insert the pics into ur awnser.

That's a classic hot air intake system...kinda self defeating. You want to draw your intake air ahead of the IC, or from the other pillar

Hello all.. Just reading along and I have something a little different in my TDI set up that seems to be working well. I have my air intake on one pillar, in this case the right rear where the original intake was. Then i bring it across the back of the engine compartment to an air to air intercooler on the left rear pillar. I have an digital temp gun and I seem to be getting good temps. Air comes in hotter than it goes out the other side which is what I think I want. Now I know I cant pull that temp gun out while driving at 60mph and check but I have checked immediately after stopping and it still holds the variance. I had a variety of performance issues but it is running really solid now. I have added fuel coolers, oil and gear oil coolers in various places that have also helped. The shop just completed a new pipe from intercooler that has better bends in it but I seem to roll fine even during a summer day at 75 with the AC on. Not sure if this helps but it is my experience. If any one thinks this is flat out a bad idea and I can get better performance otherwise I would love to hear about it. I have the van off in at the shop for storage over the winter but i could have some pics sent ...

The Mack Maxidyne diesels (1960's and 1970's) used compressed bleed air from the turbo to drive a small air-powered turbine that drove the integral fan in the intercooler air-box. Nice design in that higher boost drove the cooling fan faster and vice versa. No pesky electric fan for the Mack, nosiree . . .

Does anybody have pictures of the body modification s necessary to vent to the rear or underneath (is this a low pressure area)?

Would the fan sit on top of the Saab intercooler and pull air into itself and through the intercooler or would it be better to put it under the intercooler? Maybe doesn't matter?

To defeat the pre-heating of the intake air, you could install a water methanol injection system above the charge cooler in the pillar. It would cool the charge cooler, the intake air and keep your EGT down too. Just saying...

So I was looking at this for my TDI.

Is this what you are thinking?

i thought i would post up a few pics of how my intercooler is shaping up

internal division to balance cores equally

better idea here

mock up

position of fan sensor

kit form

fast fwd

used the cad cutter to make the inlet flange mount as its 10mm conical,this is important as a flat plate with a stub would render it likely to flex in and out and over time possibly cause fatigue cracking

here the fan mount is welded to the end tanks and the 90' fold is sufficient to prevent movement that could be an issue, also the fan is now securely fixed via SS rivnuts/capheads and is i think a decent way to do this.

and so we have this

so now i will place it and make a simple effective mounting for it

Very nice craftsmanship.
Post your results when you get a chance.

I have a WAIC unit (Frozen Boost)I am just now hooking up. My fan is about the same size as yours but it's cooling water.
