I made up a carbon fiber intake manifold and I've cut the stock intake manifold down to basically the flange w/ injector bungs.

I'm having a hell of a time figuring out what kind of epoxy I need to use to get these parts successfully mated together!!! argh, anyone have any experience with this can point me in the way I need to go??

 

A construction type of exopy paste is the only thing that i can think of that would come even close to working and it is made for concrete. Product is by sika (i think).

only thing i can think of.

 

Go to shop that builds racing shells (boats). I have a friend that works at one and they bond ALU to carbon all the time.

V13(0,1)5 is supposed to be the shizznite but i dont know if you can buy it yet.

I assume you mean the stuff they use to hold like the aluminum railings and all inside the boat frames, etc??

I've thought about that stuff but wonder how it will act under higher heat and long term heat cycles that it will have to deal with under the hood.

hmmmm

 

Dude i didnt know you hung ot here..lol..oh and me?.i do too..LMFAO.....anyways..what ive seen work good is to mold through the flange and build it up on the head side of the flange...(you can cut a recess in the flange to make it flush) but im going to make it the size of the flange and sandwich it between the head and the flange...my injector bungs will be on the flange and ill use a plyable sealer from the flange to the runnders that way if it exspand or flexes like stuff does in extream enviroments itll be able to give...................Hal

 

I understand what you mean, I just know that endyn doesn't do it this way and I'm basically trying to find out what epoxy they use without asking them directly (since I know they wont tell haha).

figured this might be a good alternative in the future after I'm done with my first manifold. you know, something to play with in my spare time.

Endyn doesn't build that manifold. They sell it and had some R&D into it. Another company actually builds it. Not saying that they don't know what is used though. Just clearing some things up.

 

on most that are made like that the will machine a groove in the Flange and a small ridge on the runners then pop the flange into place along with Epoxy that way there is a mechanical bind...i just wasnt sure how well i could copy that with out CAD machines and under 25-30PSI of boost........................Hal

 

shouldn't be hard if you make your "woodie" mold right

 

SUPPOSEDLY they don't use anything at all. When the first pics of that manifold came out, they said it was a compression fit and nothing else. Sounds like BS to me but that came from one of the designers here on HT I believe (may have been another board). Do a search and see if you can find the threads on it.

 

well i could mold the ridge area into the runner but im laying the mat over the mold and as i make it thicker itll change the shape and not be right then im back to shaping it and such but the reciving part in the head was my concern............Hal
