This is what the AMS kit did. If you look it up, there are still pics of it on the interwebs.

Remember, you agreed to be a test subject for this thing once I get it sorted out.

By the way, I got the pictures you asked me about. Using the Dodson sump, I figure the more air through the radiator the better. The new cooler looks like this.

It still has the SPAL fan on the back.

The last time I had it on the track (with 50 degree F temps), I didn't need the cooler. I sure did need brake cooling.

And, AMS has to get some return on investment with sometimes cheap Evo guys that are used to big things for not much scrilla. Engineering a moulded part that won't likely fit all Evos...that won't cause some sort of legal trouble...that cools hot brakes for 0.0037% of customers...

I just spent 12 hours building an ugly piece of plastic that will need 2 lbs of Bondo just to work for my car. With the cost of carbon and labor to produce one part plus all ducting and other things...good grief, who could make a marketable product out of this??

Excpet AMS just used an aluminum pipe. There wasnt anything crazy with ther brake cooling system other than there custome dust sheilds. Thats about it.

If you have Dodson sump I think that you don't need any cooler so far. I would log temperatures with it turned off, but pretty much there should be zero usage of it.

I love your cooler idea. And I'm desperate to be a test subject for your brake set up....once my car actually get GET ON TRACK, I'm sure I'll be cooking my brakes silly-style

The fabricating in this build is amazing. Those stocks you made were absolutely gorgeous. If you don't mind me asking, what's your day time job?

Sometimes I wish I had a 'day time' job...I wouldn't be sitting on a plane right now going from LGA to ORD. Some call me a consultant.

I can answer the grade school kids question about what he is going to do with math, well, statistics.

I have made some progress on the tunnel for the passenger side but still have to figure out how to make it into a mould. It seems straightforward but by the time you get vaccum pumps, plugs, holes, and pipes figured out, not to mention female from male, things get complicated.

Crap, I just know Morricus is going to quote that last sentence.

Well, it is not my idea. I stole it outright from a conversation with Eric at Kosmic Motorsports. I think they might be working on a comprehensive solution that works with the Dodson sump.

Look up Rooduct intermedate brake cooling ducts on fb. They make ducts with fans.

I kinda think its overkill for my application

I see are ducts for Subaru, Nissan, and Mazda but nothing for Evos. It looks to be the right idea.

I worked some on the duct that routes air in front of the engine.

I don't know if it matters much that the duct is somewhat boxey. I guess it would make more sense for at least the ends to curve around smoothly.

Thoughts??

Dude, you're an engineering freak! These look perfect. I'll take two.

I'll have that thing looking swell with a few coats of paint. Thank goodness for bondo.

The thing is...how to convert this to a hollow duct isn't obvious. It would be good to avoid a seam in the construction. If I had a 3-d printer, I guess it would be simple enough.

One approach I can see is to build a mould to exactly replicate the pattern I have now. Then, I could form the piece in paraffin and wrap it in carbon fiber / kevlar and vacuum press using an infusion. Once cured, the duct could be heated and the paraffin poured out.

 

[Mnemuth]

I guess another option would be to make mould that is the reverse of the pattern and use an inflatable bladder to compress the carbon fiber from within the mould. One advantage to this approach is that the outside of the duct would be nice and smooth.

This could be done with vacuum, I believe, if one set it up correctly.

 

[Mnemuth]

In order to clean up the inputs to the duct, I applied some wax as a release agent to the inside of a piece of 3" PVC pipe.

It is a good idea to pull the pipe off before the plastic is completely cured.

I took some time to round the ends of the duct.

The kink in the middle could be smoother (on the right side in the picture above), so I might do that as well. I took some measurements and it appears that there is no loss of cross sectional area using the duct.

I need to do a test fitting next to make sure the clearances are good and take a look at mounting points. Also, I have been considering whether it makes sense to fabricate a duct (3" pipe) from the front to avoid using flexible hose.

You sir have mad skills. You are on a whole other level. Nice work!

Everything looks awesome

I am also interested in being aguinea pig

Exactly what I was thinking reading his posts and why know one has responded with suggestions. Nice job man, some serious talent.
