Default factory hose upgrades (the braided stuff) anyone do this? Any reason why you shouldn't? Clamps?

I'm thinking about replacing ALL factory hoses with silicone ones and adjustable/reusable clamps.

So ignore for a moment all of the hoses in the Samco kit, the F-Hose, and the TBB.

I'm talking about all OTHER hoses, like all of the vacuum lines and such (black braided hoses).

I'm thinking of going with a silicone high pressure hose line, something thick walled and durable like this:

Any reason this would be a BAD idea?

Also, what are the BEST reusable clamps for varying hose sizes and where to buy them?

Thanks...

Default sounds like a good idea to me- but why? fitting them might be a pain though

Also, it may be an urban legend, but does silicone expand under heat?

Default wow...you'd have a real psychadelic rainbow motor :)...those are

some small hoses to put a reusable clamp on...if you can get away with zip ties in some locations, go for it...otherwise, you'll probably have to go with the crimp style clamps for hoses that small...as long as those hoses don't break off easily, that would be cool...i had some nasty piece of hose...(don't know the exact material)...but it was glossy and the stupid thing could be torn apart by hand...it's like it was made out of sugar or something....
broke like pixie sticks.

Default Why is cause the factory hoses are rated for certain pressure...

If I increase that pressure, I'm putting the reliability of the system at risk.

In the interest of "over building" the underlying infrastructure that the charge pressure in the S4 must follow, I'd then feel better about raising the charge pressure amount.

Also, the factory hose clamps suck.

Default Actually, I just mangled that stupid braided hose from the driver side BPV and was looking to

replace it. So I'd be interested. The only thing that I would guess would matter is keeping the volume and the length of the hose close to stock.

Default

Absolutely...the only thing I plan to change is the hose material (silicone) and wall thickness...

Default Well, why not chip your car at the same time...

Because that stuff will be as deadly to your warranty with our pissant norcal gestapo Audi reps...

no doubt about that, but I'm not talking warranties, I'm talking about reliability...

Default clamp info...

go to this site and search for "machine screw hose clamps", if you want the stock clamps search for "ear clamps"

If you are using the stock braided hose, you'll need the 6-8mm, you may be able to go up one size, especially if you have forge valves since the nipple is a bit bigger, but the 6-8mm will fit, just kinda tight. not sure what size for the thicker one on the passenger side...i just replaced that w/ a braided one...<ul><li><a href="http://www.mcmaster.com/">http://www.mcmaster.com/</a</li></ul>
