So I have a concept after seeing something I liked.
Companies produce carbon fibre intake pipework. Carbon fibre having approx 40x more heat resistivity than alloy this is good news. But problem comes when trying to add sensors etc...
So...I'm contemplating making a second skin of carbon fibre pipe that will effectively just slip over all existing pipe work.
Not only is it more heat resistant but there will be a small air gap between the outer skin and inner. This should reduce heat soak.
What are people's thoughts. I know we have some very bright people on here.
I was planning on using some guttering as a mould and knocking it up myself. Can't be that hard :-\
And should be relatively cheap.
I like the idea of this. Where did you get your inspiration from?
Sounds like a worthwhile experiment.
You'll need a small vacuum pump and bag to get a decent result, though...
Sounds like a good idea, carbon fibre always looks good.
"Can't be that hard" famous last words :)
I'd suggest do the maths before making the pipe. Should be quite possible to figure out flow rates and heat transfer to see if a warm alloy pipe is significantly heating the inlet air. I doubt it is personally.
I'm sure you already know but generally carbon fibre products are baked in an autoclave to cure the resin etc, if you don't pre bake it will it shrink the first time it gets hot?

I'd say that the amount of time that the air is in the pipe, the radiated heat from the pipe probably wouldn't do THAT much to the air in the way of heat transfer. But on the other hand..... an engine bay full of carbon fibre would look good...
Everything is worth a try but my gut says that with a small efficient turbo at low boost levels there will be no gains.
I like it. Go for it
Son and I were looking at remaking the stock metal heat shields in carbon fibre
Currently looking at pricing, probably be quite expensive, but will look cool
Yep love Carbon fibre in the engine bay. I've got a carbon mods cover it's mint
It was mainly the carbon fibre pipes that I thought about putting a slit in one side. But tbh I reckon makin my own could be a decent solution.
Thanks for the info on the baking. I'll look into this.
I plan on it being a very cheap mod so the finish will have to be best I can get unfortunately.
I reckon around the area of the turbo will be most benefit if any...failing that. I have a cool carbon bay :)
Have a go you might surprise yourself. If your using downpipe as a mould, if you need to make bends, fill the downpipe with sand blank it off both ends and gently heat with a heat gun and you can manipulate the pipe to replicate the bend, leave it to cool and you have a pre formed mould. I made an extension pipe for the air intake that went into the side scoops this way.
Well that's genius.
My only issue I'll have two sizes of pie but I'll just do it twice I guess.
Just bought some off cuts for a few who'd online so will have a look at what this idiot can produce. :)
Edit.
I'll also try and get some recorded results as it should be easy enough to remove and replace.
If you don't bag it, it will tend to crumble when a bit of heat gets into air pockets.
Mind you, once you've got the set-up for doing it, who knows what creative stuff you'll come up with?
Ahh. So it will structurally affect it if I don't rather than just give it a nice finish. That's a different story I guess :/

For cosmetic trimming etc you can just about get away without using vacuum or baking but if you want any kind of rigidity/durability then you definitely want to suck the resin into the cloth if nothing else.
