DeusEx Posted January 11, 2005 Share Posted January 11, 2005 Hey guys, Does anyone know where i can get a custom airbox/plenum style made up for my triple webers (in AUS) or anyone in the Hybrid community who makes these and would be willing to ship one? Heres an example http://www.classiczcars.com/forums/attachment.php?attachmentid=6864 http://www.classiczcars.com/forums/attachment.php?attachmentid=6865 Thanks Quote Link to comment Share on other sites More sharing options...
NZeder Posted January 11, 2005 Share Posted January 11, 2005 Have you checked out http://www.tweakit.net/shop/ (Australian Site) they sell all kinds of stuff might. I know I have seen on this site a setup for twin carbs so they must be able to get the airboxes for a triple setup. Found it on their site check here http://www.tweakit.net/shop/product_info.php?cPath=57_49_50&products_id=143 Quote Link to comment Share on other sites More sharing options...

Guest 240zJake Posted January 11, 2005 Share Posted January 11, 2005 I'd say just bust out the fibreglass and goto work maybe use wood as the mold in case you want to make more... Quote Link to comment Share on other sites More sharing options...
mark Posted January 11, 2005 Share Posted January 11, 2005 I made one years ago. Turnes out pretty good. Used a flat thin piece of aluminum and cut tabs and bent it in a bench vise using 2x4's as a break. Used the carbs as a template and hole saw to cut openings for them. Front bolted on the box thru the carbs where the air filters used to go. I mocked it up in card board first to get the dimensions right. Used JB weld to seal the seams from the inside. (an epoxy) Only took a few hours and it was cheap. Mark Quote Link to comment Share on other sites More sharing options...
preith Posted January 11, 2005 Share Posted January 11, 2005 Not the best pic, but I was trying to get the air filter in front too. I just bent mine out of 6061 .040 aluminum. The backing plate is 1/8". I had a K&N backing plate which I used as a pattern. Just hole sawed the inlets and fine tuned with a die grinder. You could probably get away with just bending up more of a box shape than mine, but I needed the clearance below the bracing. http://zdriver.com/gallery/data/500/30883006094-R1-035-16-med.jpg Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted January 11, 2005 Share Posted January 11, 2005 Here is what I am looking at for a forced induction set up on my sk racing carbs. I am planning on using 4x4 aluminum tube stock with addapter plates on each carb. http://zacksz.homestead.com/somehotz.html Check this out now Quote Link to comment Share on other sites More sharing options...
DeusEx Posted January 11, 2005 Author Share Posted January 11, 2005 Havnt got a bigger pic by any chance Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted January 11, 2005 Share Posted January 11, 2005 Here is a drawing of what I was planning to build. I am planning on running velocity stacks on the carbs, not shown. My carbs have a 9" or 229mm take off for the intake and carbs, so the 4" - 102mm tube stack will work. Quote Link to comment Share on other sites More sharing options...
preith Posted January 11, 2005 Share Posted January 11, 2005 I just made one piece for the entire width of all three carbs, sandwiched in between the air horns. At least on my Mikuni's there was no need for additional clearance. Quote Link to comment Share on other sites More sharing options...
heavy85 Posted January 14, 2005 Share Posted January 14, 2005 I've made an aluminum baseplate and sandwiched it between the carbs and airhorns and made a template for the box but there's a few details I haven't yet worked out. First - how to seal the box against the baseplate. Second - how to hold the box to the baseplate other than zip ties or bungee cords. Third - how to secure the hose to the box. I'm thinking in the first issue to use some type of soft rubber lip seal if I could find something that would slip over the edge of the box. On the second issue I'm thinking of using a long bolt or threaded rod kind of like a stock airbox. The hose connection is the biggest unknown but I'm thinking if I could find the lip seal stuff I could make the hose cut-out a tight fit and line it with the seal for a 'press fit' with the hose. Others who have been there what's you suggestions? By the way the TWM is actually $360 for the three carb one! Thanks Cameron Quote Link to comment Share on other sites More sharing options...
preith Posted January 14, 2005 Share Posted January 14, 2005 I wish I had a digital camera, but I used these latches, 2nd pic down on left: http://s2.pegasusautoracing.com/086.pdf I then welded some tabs perpendicular (basically a T tab) on the top and bottom of the backing plate to hook the latches in on one side, and hold the box centered on the backing plate on the other. I bent the box up on a brake, and simply bent the edge over 90 degrees, so about 1/2" in parralel with the backing plate. Quote Link to comment Share on other sites More sharing options...
