bahtenduh Posted March 27, 2009 Share Posted March 27, 2009 Hello everyone. I'm hoping to get a little insight on a project i'm working on. I am making a forward facing upper intake plenum for my RB. I was looking at Monzter's intake build and see that there are some very knowledgeable guys here so maybe i can get some good ideas. Here is the baseplate bolted to the lower runners. I am going to make the plenum out of carbon fiber and will have a flat portion around the perimeter of it that will be bolted to the baseplate. It will be 3/8"-1/2" wide and i will be making a retaining "ring" to distribute the clamping force and even out the load. Hope that makes sense. Here are a couple pics of this. Cross-sectional view. Top down view of what the retaining ring will look like. The grey dots are the fasteners. I don't think i will need as many as i have drawn if i use the retaining ring though. Here are some pics of the wooden buck/mold i made to show the plenum design from a few angles. I will probably be making another out of foam to make the layup process easier. Wood is kinda heeeaaavvvy. Plus i am hoping to get some feedback from you guys about the design of it anyway. I also noticed in Monzter's IM he used diffusers inside it and that is another area i would like some advice about. Anyone with some ideas to keep flow even to all cylinders would be really appreciated. Matt Quote Link to comment Share on other sites More sharing options...
The love of JDM Posted March 27, 2009 Share Posted March 27, 2009 I have no experiance in helping you out but that is a really cool idea and something I would be interested in down the rd after everything was bench tested and #'s ect if you decided to sell something like that.

Challenger Posted March 27, 2009 Share Posted March 27, 2009 I beleive someone already did this for a RB. Looked awesome. Search for cf intake or something. Quote Link to comment Share on other sites More sharing options...
bahtenduh Posted March 28, 2009 Author Share Posted March 28, 2009 Just found the thread you were referring to i think. Hasn't been tested on the motor yet though i guess. Quote Link to comment Share on other sites More sharing options...
Challenger Posted March 28, 2009 Share Posted March 28, 2009 Is it the thread where he used a router to cut the holes and then made the carbon fiber piece to fit on the side? Quote Link to comment Share on other sites More sharing options...
bahtenduh Posted March 28, 2009 Author Share Posted March 28, 2009 Yeah he has a build thread going and looks close to starting the motor up. Plenum looks really good. I was going to do it like that but got a lot of feedback about using just adhesive and changed my design. I think the big drawback is the surface area of the part that will be bonded. I actually got some response from the company that makes (or made) the CF intake manifold for the Honda B18 (AIR) They are working on one for the Toyota MR2 now. Another reason for using mechanical fasteners as opposed to adhesive is the ability to change the plenum design and maybe add some diffusers to the baseplate to direct flow evenly to the individual cylinders.
