Im in the process of making carbon fiber upper charge piping. Ive recieved quite a few IM's regarding the status on the piping. We are having trouble with the mold due to defects left from welds/bov flange etc. Presently im looking for a one piece upper charge pipe w/out a bov flange ( Any one know who makes one, or if you want to let us borrow one we will use to it make the mold and sent it back along with a CF pipe ) Once we get one we could have the mold done in a weekend Anyways heres a few pics of a little intake pipe we made for my m3 today (the charge pipe will be made out of better quality CF and have a lot more finish work, this was just shitty carbon laying around and sprayed with krylon clear, no finish work done )





Also the quality is not perfect on this pipe (cosmetically), its the first pipe we have made, they will get ALOT better as we make more The pipe is VERY strong, my 250lb friend jumped and stomped on it for a good minute straight

 

might want to try a CAI, if you're looking for a flangless "charge pipe"

not a bad idea...

 

Mpir3 I sent you a PM

very interesting, keep us posted

 

yes, very nice, keep us updated

VIDS!!!

 

great to hear, keep us informed

 

the greddy kit doesn't have a bov flange on the charge pipe

 

looks pretty good, wonderin how it looks with everything under the hood !

like a carbon fiber pipe next to a motor?

 

oh how i love carbon fiber.

 

very nice mpir3. you wanna sell some to me for $50 shipped

you should be able to figure out who this is...

 

unless you are using RTM; why would you want to have the outside the smooth surface and the inside the rough surface? Yeah it may look pretty but it wont flow near as well and will be very turbulent...please give detials on the layup process that you are using.

its not RTM, im personally not doing any of the work, My friend and his father make noses,wings, diffusers, etc for formula atlantic/continental and zetec cars. I'll try to have him post about the layup process...

 

whats the status on these?

I hope you mean it the other way around. Turbulance on the inside surfaces is a good thing to keep up the velocity on the interior of the tubing. It's the concept of the golf-ball dimples. Bad turbulance (which is what you are thinking of) actually happens in the bends. When, you're trying to force the air, with said velocity, to alter it's direction in such a confined area it tends to create turbulance that slows the total velocity of the air. This in turn causes a lower mean velocity of the entire charge pipe system. This is why you need larger pipes when you get into the larger HP #'s. Also why a 3" exhaust is better.

That is if it's not hgely rough, but I doubt it. Sorry I didn't see his reply to this, so NVM...

Back OT - Nice fibers

 

looks pretty sweet. wonder how much it'll cost tho?

 

Turbulance is NOT a good thing for flow EVER. The dimples on golf ***** are there to keep the boundry layer from seperating from the golf ball as it spins though the air. Key word is spins. Turbulance doesnt produce higher air velocity either. Higher velocity air normally makes the air more turbulant but not the other way around. The only place where you want turbulance is in the intake runners after the fuel in injected to promote better fuel atomization. You want as laminar flow as possible at all times, except for the one mentioned above.

 

I'm also still very interested in the charge pipe. Please keep us posted.

This is the explanation of laminar flow and turbulant flow. This is for a golf ball, but does describe both types of flow and what they are good for.

 

nice

 

That is a terrible idea. So, you're just going to clamp rubber or silicon hose to a little piece of carbon fiber? Why?

You can't buy CF and custom fit it to your application and weld it up like you can with aluminum or steel. You can't weld a BOV flange on.

Is it worth paying 10 times as much to make your life tougher, all for a little "bling?"
