Yes, CF. The inside diameter varies. You really need them to fit clsely but a large gap will not kill the effect. Just getting air in there is better than no ducting

 

Well, I know of three people (including myself) so far interested in ordering the ducts. I guess we need two more orders...

 

Are these going to be for stock rotors?
I am interested but I want them for M2 racing AP brakes.

 

Actually, they can be made for any brake setup you might have (within reason). It should be no problem for your setup...

 

Then, I am in for a set.

 

Nice! We are up to 4 now... Just one more!

 

I know others commented, but damn, those are some stratospheric speeds. I don't think that I have ever heard of anyone going faster on the straight at Summit than they do at VIR.

I saw an indicated 160+ on the straight at Summit Point once. From the passenger seat of Cam Worth's 3 rotor it was pretty exciting. (the fun part was passing 3 cars in the braking zone).

And I agree with Brad, hope to see you on track there this summer.

 

Yeah, I was surprised too. I did a couple of events at Summit before going to VIR in this car for the first time, and I was expecting that I would be getting higher speeds on the back straight at VIR than the front straight at Summit. Not so...

It has to do with the turns leading onto the straights. At Summit, you come onto a very long straight from a very fast, straightforward corner. No real complexity there. The front straight at VIR is really a constant turn, coming out of hog pen, which is a fast complex, but not the fastest section in my car (the car is constantly rotating the entire time through, so it keeps me on my toes with the throttle). If I were more aggressive through hog pen, I am sure I would hit a higher top speed than I have on the front straight, but I still don't see it matching the front straight at Summit. Summit's front straight really is straight...

As for the back straight at VIR, just think oak tree. Then it is not surprising that the front straight turns out to be faster. And that is easy to forget, until you hit the track!

So if you think about it, it really isn't that surprising that the "faster" straight is Summit, given the car.

And as for the speeds in general, to reiterate yet again, 2600lb wet with 400hp. Pretty obvious now, yes?

 

To get back on topic (once again), we have 4 people "signed up" for these backing plates. We just need one more person, and we have an order. For those who are in on it, I heard back from Nick about the setups that you guys told me you intend to run the plates with, and he can make the plates for all of them, no problem.

Minor request - anyone who has questions on the setup of my car or speeds on track, please PM me and don't add further clutter to this post! This thread is supposed to be about brake ducts for the FD, as the subject implies.

 

At VIR Full, the front straight top speed is about 5-10mph faster than the back straight. I don't look at straightaway speeds often, it's about cornering and exit speed anyway.

 

I agree. That is about the difference I see between the two straights as well.

I am a "twisty" kind of guy also - not very interested in the straight-line stuff! I have the most fun keeping at the limit on the corners. That's where the adrenaline is! The straights are breaks, good for a quick rest of the muscles, checking gauges, etc.

 

Sign me up for a set. I assume this is for the backing plates only and I have to fab my own duct tubing.

E-mail me payment details at rx73rdgen@aol.com

 

Nice! We have five - now we can make the order.

John, yes, these are the backing plates only. Which brake setup do you need the plates for?

 

Am I too late? I want a set too.

 

Sorry, I've been very busy for the last few weeks, and only just got around to calling Nick.

So he is going to deal with each of us ordering the plates individually, as far as collecting money, getting shipping information, getting any necessary details for fitment, etc. He needs names, daytime phone numbers, and shipping addresses for all of us.

I am supposed to email him all of this information, then he is going to calculate shipping for each of us, and get back to each of us individually with a quote. Then we can send in our money separately, and in the meantime, he will make the plates. I guess there have been some other inquiries for FD backing plates too, so he is going to make note of this purchase on his website for anyone who happens along.

So if you guys who are in on this want to PM me your name, shipping address, and phone number, I can send this info off to Nick and get the ball rolling.

 

Okay, I gathered everybody's information and compiled an email to Nick. He should be contacting each of us in the next few days to let us know what the total will be with shipping.

FWIW, anybody else who is interested can still get in on this buy. Probably best to contact Nick directly, though. I have already done my part!

 

What kind of lap times do you guys turn anyway (VIR North and full... and what the heck, SP and any other tracks you've been on)???!?

When you say "summer" at VIR with MADs, you mean this June, right? If so, please have that passenger seat in as I hope to find you!

 

I called Nick today to get in on the GB. He says that these ducts will be made from fiberglass, not aluminum like his previous ducts. I don't really care whether they are aluminum or not, as long as they can withstand vibration, heat, brake dust, grime, etc.

 

That's news to me - I asked about material in my last email to Nick, but I haven't heard back from him yet. Seems consensus is that he knows what he's doing, so I assume he has good reason...

As for lap times, it is common to associate high straight speeds with good lap times, but this is often not the case!

 

I just installed the old aluminum ones on my car (soon to be someone else's car) and took photos. I would like to post a "how-to", because I was furious there was no instructions...small details like...YOU NEED A 36mm SOCKET WOULD HAVE BEEN NICE!!!!!!!!!!!!!!!!!!! And a nice Grinder to shave down a steal knuckle!!!!! How about some air tools to remove the hub!

 

How do I post photos on this joint? It seems I have to post them to some other website and link them here...is that correct?

 

Here are the ones that i built for mine (pics are test fitted) One of the big issues to me was making them removable/installable without taking the whole damned hub apart. Hey BB, or Bill...you guys going to VIR in Feb? Looks like i might make it out of the desert in time to go now.....

 

No - just use the "Post Reply' button to get to the post editing screen, insted of the quick post box at the bottom of the thread - the edit screen will have an attach file field w/ a Browse button - browse to the file you wnt to attach and the submit the reply - there is a size limit so you may have to crop &/or compress the image to get it to up-load. To make the image appear in the post insted of just being a link, you have to edit the post & copy the link the forum created into an Image tag pair (use the "IMG" button & "Close Current Tag" button at the top of the edit window.)

 

That's a nice setup...did you use a 2" hose? That looks much better than the setup I have which uses a 3" hose making it a very tight fit for the routing the hose. I suppose I can use a step down adapter from 3" t0 2".

Where did you get the hosing from? The aluminum expandable hosing I bought from Home Depot doesn't hold up too well.

Thanks in advance.

cheers

I also installed aluminum screening to catch any rocks or debris, see attachment
