Carbon Fiber SRI/CAI anyone?

I dont think its good idea for CF hardpipe, there might be leaks. Steel is still a better choice for hardpipe.

Actually steel is NOT the best material.

I like stainless myself. Aluminum is nice too.

Actually metal is not the best material. Again I have asked several engineers here at work and all say the same thing. Plastic is best. It will conduct less heat. I would also venture to say CF is also better than metal.

 

[vindication]

yes, cf better. look at top end cars and racecars. you see cf in their engine bays

^ what he said

I have figured that CF hardpipes with integrated steel components at either end (only where they connect, or at least on the side exposed to the heat of the turbo) would be the best compromise, giving you the look and the performance of the CF while ensuring that the portions under the greatest stress (where connections are made) are all steel. My $0.02.

Hum, if just for looks, we can just put 1 layer of CF on top of our FMIC, whould that work?

I am one of the tester for Riles CF CAI system, I am starting a new thread to report my finding on his CAI. I will keep updating everyday.

i'm soooooooooo buying one. thanks riles !

Just got it installed
here is the picture

Lookin pretty sexy! That's the blue kevlar weave right?

Damm I can't see the pic....they block personal space at work.

 

[daedalus]

looks very nice. I dont really like the blue weave, but what ever makes ya horny.

I would be intrested, but is there any way that the weave can stay straight instead of kinda shifting around like its twisted? I"m not sure about the manufacturing process hes using and if its just not possible.

Either way. Looks really nice, and I cant wait to see the SRI version.

We are working out the little bugs with the testers right now. I have to change a few small clearance-type issues before the sales start, so I am going to make another test intake (but I'll just put it on my car, we don't have to wait for another tester to receive it) to make sure I can work out all of the bugs.

daedalus- its tough to make it perfect, but I will definitely do my best!

The whole point of carbon fiber is that is has a tensile strength similar to steel with 10% of the weight.

She's too skinny...I think I'd break her.

I'm thinking more along the line of compressive strength here. Where each pipe is clamped to a fixed structure (i.e. the turbo outlet and the FMIC/SMIC inlet/outlet) the pipe will be subject to both tensile, compressive, and hoop stresses since one structure is relatively mobile and the other is relatively fixed. Since the clamps need to be tight to minimize the likelihood of leaks, the component of the sum total of stresses experienced at the outlet-pipe junction will be high. If you put a steel sleeve/collar only at that point, the portion of stress that is attributable to the compression of the hose clamp is significantly reduced. Hose clamps = compressive force, boost pressure = hoop stress forces, motion of pipe relative to fixed turbo and FMIC/SMIC = tensile force. All contribute to fatigue of the pipe. Reduce one part and the pipes are better able to resist the remaining forces.

In response to that concern- I'm going to be adding extra layers of fabric around the edges (about 1" long) to provide strength against being crushed by hose clamps.

The testers seem to be doing well. I will have the redesinged SRI made by Wednesday of next week, keep an eye out for pics!
