Small details like...keep a grinder handy would have been appreciated! Photo for your enjoyment...thank God I have a lift, I can't imagine enjoying this if I was under the car.

Don't get me wrong...I fully appreciate the ducts and hold tremendous respect for Nick to come up with this elegant solution and believe me...his duct is not easy to make. It looks dumb and basic, but there is no way to make such a duct easily, the least of which the big bend required to clear the ABS sensor, it must have taken some careful thought to be able to bend it and not crush the tube.

Next time...please include a list of required tools and instructions. Photo below for your pleasure...I am glad I have that big-ass hand grinder.

Damn I am gonna miss my car :(

cheers

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?



Doug your going to have lots of fds chasing you :)
10 before the straight at Summit is a very challenging turn for me.
Try to make it to some of the seat time events this year.



Wael,
Someone is sure lucky to have you busting knuckles for them
:D

Well, I finished installing both backing plates. Its a tough job because the bend in the 3" tube that becomes the moon shaped cresent is not shaped perfectly. This means a lot of reshaping is required as well as enlarging some of the bolt holes because they were made too precise.

Overall the setup is clean. The real big step forward came after spending a total of 8 hours figuring out how to shape the aluminum air ducting I bought from Home Depot as well as finding a good location to pick up the air. I believe the solution and routing I used will have the ducts on the car for a long time.

The biggest advantage about the 3" aluminum ducts from Home Depot's plumbing department is they can be shaped, so in some areas I made it ablong, and in others I was able to clear a bracket or two by dimpling the area that required clearance.

I took many photos but forgot the camera at the shop. I will pick it up tomorrow and upload some photos.

cheers

wael,
The hoses on mine are 2 1/2 if i remember correctly. My hoses actually came from an aircraft , but i think www.racerpartswholesale.com sells it as well.

Oh yeah, Wael, i emailed you in reference to a carpart.. PM me if you're interested in working a deal.
Thanks

Just an update for anyone that ordered brake ducts from N-Tech......The ducts are done being machined, now we just have to do some bending and some welding, and then they'll be done. Nick will probably have them done this weekend or early next week. Any questions, call him up or shot him an email.

wael.el-dasher@efini.net 04-02-04 02:05 PM

Two months! I can't believe how long this is taking. There is no reason why this whole thing wouldn't take a week to do, from material delivery to finished product.

Hey, I've had to wait 7 months to get brakes from M2 Performance... so it could be worse!

wael.el-dasher@efini.net 04-02-04 06:10 PM

I waited 1.5 years to get my first brake ducts :) To think I overnighted a check and was first to send payment...

cheers

have you guys seen my ducts? mines are cf and cheaper then these ;)

DrPJM1 04-03-04 10:34 PM

Let me get this straight: if I run a dedicated brake duct to a custom backing plate I may not need a big brake upgrade?

Shawntx76 04-03-04 10:40 PM

and not to mis guide this thread any more but on spike tv i saw they had a kit to paint breaks .... anyone got good info on that?

yes and no, yes only if your current brake system is in good working condition, if your current brake system is lacking, brake ducts will not really help you.

that would be to make your calipers pretty :)

DrPJM1 04-04-04 08:58 AM

I'm easy on the stock brakes but have found them fading a little after repeated laps. Switched to Hawks but they dust up a storm. Switching to EBC's when I finish up the Hawks.
Sorry to come in late to this thread but:
how much for the backing plates in Kevlar for 2.5"-3" hose, and how much hose do I need approximately?

whoa, bended and welded? i though these were gonna be made from fiberglass or something as listed above

in anycase, mines are made from carbonfiber or carbonfiber & kevlar or 100%kevlar and are only 150 dollars, if anyone is intrested in buying a set, let me know. i have already made a set for bigisland7 and have pics of the finished product, pm or email me with your email and I can send you pics.

P.S. Mines have a larger area so that it protects from debrie like the stock sheilds do :)

rx7even 04-04-04 10:04 PM

Wael: There's a great reason. It would probably take a week unless the machine shop making the backing plates made a mistake and had to redo them, taking their sweet time with the whole process. I've been there everyday and got the same story everyday.

Skunks: I'm not sure how the fiberglass thing came into play. The 350Z brake ducts N-Tech offers are made out of fiberglass (very trick looking piece too), but the RX-7 ducts are not. Maybe there was a mix up in information somewhere.

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.

I was under the impression that your ducts only directed air at the rear face of the rotor? Where as the N-techs were a tight fit with the rotor, directing the air into the veins and nearer the bearings.

they do direct air in to the veins but mines also has a larger area to protect the inside face of the rotor from rain/water and debrie.

Nick later told me that he switched from Fiberglass to metal. That's fine with me-- I'd rather have metal than Fiberglass or CF, unless I knew that some type of fireproof resin was used in the product.

Mr. Stock 04-06-04 09:39 AM

Anybody know what type of metal?

SHPNOUT 04-06-04 10:40 PM

probably cast Iron...........:-)

SHPNOUT 04-06-04 10:40 PM

Or Aluminum............

bros0000 04-07-04 12:45 PM

The ducts I purchased from Nick's previous iteration are made of aluminum, no doubt that's what these will be as well.
