Brake Ducting and Cooling

[J. Fast]

Well, the frame rail idea is good, but holy cow would it require a ton of work to do. I had the hose and ducts in hand and started in on it. The square hole is just shy of 2.5" in diameter. I popped the rivets on the 5mph shock mount inside the rail. Looked down in there and ugh, there's more in there. A few pieces of folded steel in various configurations. Not only that, they are no where near air tight. Could it be done, yes. In a day without major mods in a pretty structural area, no. It was a risk I wasn't willing to take.
Sooooo....
I decided to build scoops or deflectors instead. Something I see on the open wheel cars all the time but somewhat adapted to our cars.

From the side, something like this... It just takes the air going under the car and pushes over into the wheel well, right at the center of the hub. Seemed to work great with a very simple hair dryer test.

Other side, same deal. Close, but not too close. At full clock it just hits the edge of the raised lettering on the tire. (not that I ever have this car at full clock, ever)

The whole thing hangs down about 2.5 inches lower than the crossmembers. (about the same as my 4" exhaust at the resonator)

Let's hope it works. If it doesn't, the next step will be to get air to these things. Getting it to the hub is tricky. My old ducts were 1"x4" oval. (aka, tiny)

Here we go again with the air under the car thing. With a splitter air will probably not ever see those shrouds. Be better off going back to the hoses.

So what's structural about aft the front strut towers? Pretty sure nothing unless you have a crashbar? Don't even need the front motormount or the front crossmember. Was a full day to build actual functional brake ducts proven to work on a championship cup car too hard? I don't get it?

Sometimes solutions take hard work and time. I keep seeing quick and cheap fixes and this cycle of failing over and over because it would require hard work or take too much effort and time to fix it right. Why not just put the time in out of the gate so you can spend it doing something else later?

Those shrouds won't work on racecar with undertray Erron. You have to physically direct air to them. As a matter of fact, you have to consolidate and direct air to everything you want cooled. You can't just throw your thumb out and say, "go that way".

Please don't be offended by my criticism, E-Dogg, we're good friends. You gotta quit hitting the "easy button" and put in the hard work for the results your after. Don't worry, my car is done and yada yada yada... I'm going to put a whoop on you at the track if you run this cheap fix stuff, watch.

I will post up how to convert our frame rails into functional brake ducts. Mine are done. When I get some time I'll snap pics and post a writup in this thread.

It's well below the splitter horizontal line. Holy hell, do you listen?

Yes, I'm tired of working on the car. I want to drive it, not bench race it for the next year.

Excuse me? Quick and cheap fixes? You haven't even raced, once, ever. How do you know what works and what doesn't? I'm so done with this.

Tell that to Porsche. It was their idea originally. They'll work, watch.

Too late, I am offended. Are you really challenging me to a race? Holy hell, YES! You can't buy talent.

Jer, I'm tired of the 2nd hand knowledge from hanging out in race shops being taken as gospel. It's just silly, saying this won't work, or that won't work. If we don't try nobody moves forward and really, this is no different than the deflectors that the MR or GTR, or GT3RS, or any other factory race car comes with. These are even lower into the airstream than the stock variety. Why do you post negative stuff but then call me and discuss it? This is also the reason, from now on, I'll keep my posts over on a forum that has open, positive discussions. At least you could say, "that might work".

Good. I won't be here to read it.
See ya...

Can you direct me to this forum? I for one find your posts rather beneficial...

You speak as if I haven't built with you, bled with you, and been there in real life to witness all the little details always being left out and not discussed. I've been witness not by what bits are carefully shared on the internet but infact in person, and for many many years. All the time that's past I've just sort of "observed" and kept lots of note to self "hrmm's" and "interesting's" that've all led up to my very observant and well founded opinions regarding the global picture of things.

You bet I ask Bob and Dax questions, I'm not building things over and trying this and that. Its one time. I'm not going spend thousands for one session and maybe 10 laps. I'm building to win, not just to say I was out there to turn out laps. Fix this and that for the time being, that's not good enough for me.

I've always been real and for the longest time, silent. Now that I've observed, and by my own accounting witnessed, does that mean I can't voice my observations and opinions? I know you Erron, not just internet snapshots. You lnow me, why would you talk down to me like this?

Too late, I am offended. Are you really challenging me to a race? Holy hell, YES! You can't buy talent.

Being competitive? Is that really what this this comment was all about? Is that what it will take for me to have a voice? I am prepared to hit the track and have covered all my bases. So let's open em up, run em wild, and go have fun!

Good. I won't be here to read it.

After all that I've done and gone out of my way to do for you, that's it? Okay? I'm going to go back to work and scratch my head as to why we can't discuss things out in the open and why sometimes its okay to be wrong, and why you would say something like that to me, anywhere?
