Your car is hooked up to the matrix. Seriously that's cool. You got any track footage available online?

Wow, you just beat us to it as we're in exactly the same process (brake ducts).
I see no ABS on your car. Do you thing that would still fit?

What size hose is that? 3"?

Nice ducting to brakes... giving me some ideas as that's where I'm at currently (brake ducting, wing and splitter)...

I like what you did there... Looks good man. On the brake duct units that mount to the backside of the spindle, did you make those or are they the ones at ISC? Also... Is there any reason you have the two ducts for the oil cooler dumping in-front of it rather than making a shroud and attaching them it 'directly'?

It is a trick. they are revalved Koni Sports with DIY extended travel sperical ball top mounts and 2-1/4" 700/400 hypercoils. They were rusty so I painted them.

Shock upgrade is high on my list when funds become available. These have worked well for a long time and years ago when I made the setup there wasn't much of anything available that was better.

I made the spindle mount duct units myself. I didn’t make a shroud for the oil cooler simply because I didn’t make one, I might do that in the future, Not sure how much it would help I think the hoses just dumping air in front of the oil cooler will help quite a bit over not doing anything but that is just an educated guess. Im planning to fill the gap between the front splitter and the front sub frame with an aluminum sheet.

I don't have a camera and I have never had one in my car on track. Yet another thing to eventually buy.

I agree on the dumping in-front is better than nothing at all. In my plans for my track car I am doing something similar only with a shroud and puller fan on the backside of the oil cooler to maximize the cooling potential of the exchanger. Looks good regardless.

Looks like I need to make a trip up north to check this car out in person. I hear there is an auto-x next month. If my car is sorted out, that might be a good time...

2.5" hose

I bought 4 of these.
NACA Ducts - 3" to 2-1/2" NACA Duct Adapter

I heated them and formed them and cut them to more or less fit two per opening on the GV lip spoiler, pop riveted them to the opening in the spoiler and black siliconed up the gaps.

The ABS sensor mounts directly where I have the hose connected. it would have to be a bit different with ABS.

He wont be at that autox because for some reason bob would rather be lapping at MRLS

Bob, i'm just about to pick up some spindles from Kurt to build very similar brake ducts. I helped fabricate some for my friend's Pro3 racecar that are similar but a little more to them and 3" instead of 2.5"

Also, i have been thinking about where to put a damned oil cooler and that was the exact spot that kept rolling through my head.

I need to talk to you about welding some aluminum. I need a better outlet on my compressor and i'm not paying 50-60 bucks for the ATP adapter.

I will be at the Alfa performance driving school this weekend the 21st at Bremerton and at SCCA autocross #1 on the 28th also at Bremerton. I won't make it to the first Chuckanut events in Bellingham on April 10th and 11th, I will be lapping at Laguna Seca instead.

I can weld on an outlet no problem.

Bob, you should turn your oil cooler over (inlet and outlet at the top). You aren't using all of it otherwise.

Damn. I've gotta get to work. You've got those Wilwood Mini Cooper brakes up front + all that ducting now. Trying to give Sav, Emilio & Bellwilliam a run for their money?

Gonna be at that April 22nd Alfa club day at Pacific?

I would almost be inclided to enclose the oil cooler to maximize frlow through it from the ducts, but then you would be missing out on the cooling from the rest of the air moving over it.
Something to think about I supose

Looks good though!

Yea I canít just look at it and tell which would be better without measurement or more in depth analysis And heck I've spent part of my working career modeling airflow through automotive cooling systems and in engine compartments.
