Carbon fiber charge pipes
 
What are your thoughts of Carbon fiber charge pipes?

Do you think it will with stand Boost and high psi?

anything else you can think of. I'm thinking about building a set and moving my Bov to the intercooler...

Depends on how many layers you put on and what process to add resin. But i think I would work, expensive as phuck though.

gbrettin 11-08-2014 06:52 PM

I can't think of a down side other than cost.

Tony @ F.I and I had talked about this. He didn't see any reason why it wouldn't work. Hope you go for it would love to see how it turns out

It's the time that would make it costly, the materials wouldn't be too bad. Now if you're comparing price to metal pipe, then yes it would be costly.

if you pay some one to do yes but if you do it your self its very cheap just takes a **** ton of time....

I'm waiting to see if these guys are going to want to start the twin build but if not then i'm going to shoot for it....i'm going to order all the stuff tonight just got to get the time...they have these for the GTR and the sell for 2500 which is crazy....

i just hove to find out how to add the MAF housing and maybe the BOV....

Can be done easily but the expensive part would be the tooling. You could over wrap a very thin walled aluminum piece that becomes part of the final part to save some tool costs. This would also alleviate any leakage concerns should you end up with some porosity in the laminate. If you are familiar with composite processing you can make good parts without porosity. Even if you running 20 psi of boost, the stress in the walls of the pipe would be very manageable for carbon fiber. I don't imagine you would want the walls to be thinner than .03" just for stability. Fiber orientation is important if you really want to optimize the strength and weight but probably not a huge concern for a charge pipe.

:iagree:thanks for the input...i'm going to be using 12k carbon fiber sleeve. i have a plan to do it with out any aluminum even tho that was an idea but i want a 100% carbonfiber. if i fail i will just wrap with the sleeve over the charge pipe...

i'm going to do 4 layers of 12k which should be more then enough...everything is ordered....price was really good to...

Thickness is 0.03" that would be .12" that should work.

I would personally never run non-vacuumed wet CF charge pipes. Its not light, its not strong, and its not rigid. Personally I dont even consider it "real" carbon fiber. Like my Seibon hood... its more like fiberglass except the cloth was sub'd out for carbon fiber fabric. For the money, its just fine. But a "real" carbon fiber hood would be more like $3000 and it would be very rigid and very very light.

this well be vacuumed

post pics of the process. I wouldnt mind learning how to do it!

.12" sounds like overkill for a wall thickness. Carbon with 55-60% resin is a little more than half the density of aluminum alloys and I doubt your current pipes have .120" walls so you might not save much of any weight at that thickness. I would aim for .06-.09".

Ya I've done a lot more reading in to it I need to shoot for .003 to .006 for the best out come...I got enough carbon fiber the wrap my hole car ...lol.. so I plan to play around with weight and strength....I know for sure it's going to be 2 layers cuz I have to integrate the maf and bov into it...
