OK, the Blaine Fab duct plenums are ready to order. Patterns are made, production alpha fits fine, materials are in stock, I'm cutting and welding all weekend so kits will be ready to ship next week.

All aluminum, TIG welded .100" and .065" thick 6061

New ARP hub fasteners included

3" stainless steel hose clamps included

The plenums will fit all known brand hubs EXCEPT the Timken newest wide body hub. I recommend SKF brand hubs.

Install is no more difficult than a hub swap - in fact easier, since the hubs do not need to be removed

Plenums fit tightly (approx 1mm clearance to rotor) to the entire inside diameter of the inner rotor cheek, forcing the cooling air into the internal vanes where it can cool both inner and outer rotor cheeks.

Cooling air also circulates around the hub, and the aluminum plenums act as heat sinks for the critical bearing area of the hub.

Accepts standard 3" brake ducting - ducting not included. Since most cars will already have ducts of some form installed, ducting is not included in the kit, but is available as an option, or may be sourced locally.

Immediate releases will be for 2 models: the LS1 caliper on LS1 upright, and C5 / base C6 caliper on a LT1 or LS1 upright using Trackbrackets or similar brackets. Duct plenum kits for other popular brake packages will be released soon. Custom and one-offs available, contact me for a quote

Each kit includes a left and right pair of duct plenums, all hardware necessary for the application and two 3" stainless steel band clamps.

Standard kit pricing:

LS1 on LT1/LS1: $355 plus shipping and CA sales tax if applicable

C5 / base C6 on LT1/LS: $295 plus shipping and CA sales tax if applicable

4th gen Fbody with Dulaney brackets: $355 plus shipping and CA sales tax if applicable

Payment via PayPal is preferred - call me at 831 427-3296, email, or PM me with model and ZIP for shipping quote, then PayPal to: ablaine (at) cruzio (dot) com

Recommended duct routing and things that help them survive:

shorten swaybar endlink till bar ends are parallel to track, then trim top of bolt end.

Wrap duct with gaffers tape where it passes thru the inner fender liner, where the tire tends to rub, and at the endlink.

Avoid full lock steering

squish the duct about 1/2" at the point where the tire will rub - add a wrap or 2 of gaffers tape here as wear happens

use wheel spacers to increase track width

Duct in pics has been in service for a full CMC season:

Not to hijack, but I wanted to report a favorable outing with Alans plenums which I ran at the recent NFME at Memphis which has a couple of hard braking zones.

I completely rebuilt my C5 front & LT1 rear brakes to include Alan's plenums on the front and Carbotech pads and they performed flawlessly. I never had even a tinge of fade with ATE Super Blue fluid.

I just love stepping on the brakes and knowing they are all in.....

I had passengers for all of my runs and they all commented on the sure braking.

Now its back to work on the brake hop however......

Thanks Alan.

I've added 3 new versions of the Blainefab duct plenums for popular aftermarket 4th gen front brake setups:

Wilwood 140-7190 6 piston SL6 with 12.9 x 1.25" 2pc rotors

Stoptech ST-40H 4 piston with 332 x 32mm rotors

Baer/Alcon with 13" x 1" rotors

YES - Definitely call Jason... :-) His TQ arm will solve all your braking woes... and you'll even like the better handling and accel from it too :-)

Anything available for ls1 Camaro with the Prospeed (Porsche caliper and rotor)kit?

Yes, I've built several duct plenum setups for the ProSpeed brakes. I include upgraded 12mm hardware for the bracket attachment, ref: http://www.frrax.com/rrforum/index.php?sho...=10173&st=0

$295 complete with all mounting hardware and a pair of SS 3" duct hose clamps.

Thank you, Bock! Feedback is always welcome, especially the good kind!

Finally put mine on for the last race of the year this weekend, especially since we're at Eagles Canyon.

Fantastic kit and I look forward to putting the car on it's nose. More good feedback on Monday.

Rediculous.

I had some brake fade in the last race at the Hallett event in June and since I was going to flush and re-pad, I put the ducts on while it was apart.

Raced this weekend at Eagles Canyon and although several folks had some fade issues, I had absolutely none. Carbotech XP-10 in the front, stock in the rear and running fresh Castrol LMA. Pedal felt better through the weekend than I ever remember over the two years racing the car.

Simply fantastic; why did I wait so long to put them on?

Another satisfied customer.

Hi Alan. I'm interested in your your 14" Baer setup. That should suit my custom 14" Brembo setup. Put me down for a set please with shipping to 30041.

Ilario - Yes, I can make duct plenums for your Brembo brakes - I'll need 2 dimensions:
- The inside diameter of the inner rotor cheek
- The depth of the rotor, from the face of the inner cheek to the hub mounting face

PM sent on cost and payment

Thanks Alan. Pricing is fine. I'll try get those dimensions to you within the next five/six days or so.

See updated pricing on the LS1 brake duct plenums, post #1 of this thread. They are the most labor intensive to construct, and I would rather discontinue them since most users now have moved on the C6 or Wilwood or Stoptech brakes. I will leave them on the available list for a while, but at a higher price that reflects the build labor. I hope that this will shake used sets off of garage shelves and back into the market.

None of the models of duct plenums will fit the latest Timken wide body hubs. I have tried to develop a reasonably efficent manufacturing process to accommodate those hubs, and it is not happening with the tooling I have at my disposal. I recommend SKF hubs.

[Pranav]

Alan, I know we talked about the SKF hubs a while back.

I've had some setbacks on the car so still inconclusive if there is any significant improvement over the Timkens, but at this point I can still recommend them as "equals" to the Timkens, especially considering you can get them with warranty at Oreilly under their masterpro line now.

Oreillys "Precision" brand has factory dimensions and is working well for me.

Different parts come in the box, so far a MOOG and a National. Both have done better than any Timken I have run.

Yeah, but if you look closely they all come out of the same factory in Korea that SKF get's theirs from. Everything about those hubs from the pics you posted are identical to the SKF I checked out at NAPA (under their most premium offering).

The nice thing is the bodies are smooth, narrow, and machine. The Timkens look like someone melted up some British cars and poured them into a mold made of leftover cement or something lol.

I just want to get through Hallet with what I have, then probably convert to 3rd gen style hubs over the summer.

[JimMueller]

I've replaced my hubs with Timkens the last few years, and replaced one just a few weeks ago. How can I distinguish widebody Timkens?

[Midnight02]

Likewise, I went with the Timken hub during my last swap and would love to know how to determine if I have the "widebody" version.

Guess I could order a set of the ducts and if they don't fit, then I know! (IMG:http://www.frrax.com/rrforum/style_emoticons/default/banghead.gif)

All hub bodies used to be cylindrical in shape, then Timken came out with a slightly tapered, wider at the bolt flange, version. These would fit the duct plenums with a little trimming. Then they changed to a more wider at the bottom, more tapered shape body. These do not leave enough flat space to adequately anchor the duct plenums, and in use do not show any substantive improvement in service life over the earlier versions.
