Thanks for posting the picture Mark! This past weekend while testing @ Buttonwillow we came off track & the brakes were cooking.. So more than ever now we will be working on ducting.. This is a great way to get air in the front!

Matt opened up the rail and capped off internally and added a curved piece to turn the air. 18 X 11 wheel no problems lock to lock.

With the Anvil lower front valance it is wide open for brake ducts. We squared off the end of the frame rail and removed all the bumper bracket holes. Then added front duct that pull of the opening in the lower valance.

Now that you guys figured that I can post the rest of the pictures when I find them.

With Carbon Ceramic Brakes you need a lot of air flow to cool the brakes. Especially when you are making 875 HP. They don't have much thermal mass so much the cooling needs to be by air flow.

This is the general idea.

The lower valance is open and the outer courners are brake cooling ducts and the center is for the heat exchangers.

I was expecting animation with narrative from the science guy.

Nice work.

Very cool.

A lot more holes to plug in an OE sub, but it might be doable.

Someone needs to con Mark or Paul into posting pictures of the rest of the hand fabricated duct work Matt did for the front brakes. They are a real work of metal art.

Mark, Is it safe to say that a majority of the cars on this site would see a disadvantage to this set up? I distinctly remember Wilwood telling me that many don't get enough heat in the brakes to make them perform at the top of their capabilities in our segment.

I expected that some of work you did on the new Z28 would trickle down into your new 69..

What are your thoughts on traction control for these old hot rods? Currently researching Racetronix & Bosch Motorsports ABS..

I'm inclined to believe that cooling would help Wilwoods A LOT. When I ran their brakes on my Camaro the aggressive street pads faded quickly, and the track pads worked right up until the time I boiled the brake fluid. I'm probably about ten development cycles behind Mark though, but stainless or better pistons and some cooling look to be an improvement.
