How much heat can braided hoses handle? Would the be suitable to use for the turbo water lines?
Any ideas? Thanks

im using these on my car also shane...im sure they are a lot more resistand to heat than normal rubber!
Sorry no real help 
I'l wait to see what you're informed

That's what I'm planning on using for mine, & I guess it comes down to the exact composition of the braided hose that'll determine the temp it can take, but I'm pretty sure any of it would withstand greater heat than rubber hoses. Braided lines are prolly most often used with hydraulics, which gets damn hot!
OK, just looked at an Earls catalogue, & their braided hoses are up to 300*F and they're rubber hose is 250*F.
EDIT: 300*F is only 150*C, how's that, less than I expected.
I also just checked out a speedflow catalogue, their braided hose & their rubber hoses are good for 300*F.

300F thats only 150C roughly  I'm sure a turbo would be getting hotter than this?

sure, if the line is touching the exhaust housing ormanifold then the heat will be MUCh higher then this. Howevere since it wont be touching the line will be more then enough for the job.
Another thing. Oil temps shouldnt be this high either. so nothing to worry about there.

So I should run an air gap between the braided hose and the turbo water flange?

I use braided on my oil lines for the turbo, no problems, i also use adr approved braided brake lines aswell.

Yeah I'm not too worried about the temp of the oil really. I'm just worried about where the hose attaches to the flange on the turbo, and also having the hose running close to the turbo its self.

I would also like to use braided hose for my oil lines as well but because the feed and return are on the same small flange it might be a little hard to make them fit
Got a photo of your setup?

Oooh, so you've got a ball-lick of a water inlet I guess, how does the water hose attach to the flange that bolts to the turbo? Is it just a rubber hose, beaded tube & hose clamp or what?

Yeah its a ball lick one 
On the turbo there is a small oval shape flange that is bolted on. On that flange there are 2 tubes welded to it, one in and one out.

how much are braided break lines.. ae86.. and a shop that stocks them.. or do like toyota stock some?

Nah to my knowledge no toyotas came out with braided lines?
All my oil cooler, remote kit hoses etc are all gonna be braided

Whether a line is braided or not has no effect on heat capacity or resistance. That is up to the material inside them.
Typically, the braiding is primarily for increased protection of the hose (against rubbing or harsh environment), assists in reduction of flex (why they are better for brake pipes - although for road cars they are not worth the price difference), and lastly, bling factor.

Your wrong. The stainless braid absorbs the heat and dissipates it into the rubber hose. A braided hose will break down before a standard rubber hose in an environment where heat is a problem.

You are partially right, I stand corrected.
What I was referring to (and I didn't state it that clearly ), is that depending on the spec of the inner liner material (be it rubber or teflon - I have both types that are ex-aircraft) as to what heat it can withstand. The temp ratings are meant to be the fluid that they contain, not the environment that they are in.
That is usually a spearate spec, and also one of the reasons that you can get heatproof sleeves/material.
Then again, you can get those super-blingy sleeve kits from Autobarn

I knew what you mean  I just want to use braided lines because having bare rubber lines sticking up off the turbo would look crap.

Hi Gang - Thought I would share the final completion of my crazy oil cooler set-up that is going on my 20V Turbo.
I ran the car for first few hundred miles without an oil cooler and when I dyno'd the car, the oil looked like it had turned to water, so I challenged myself to build something unique, aesthetically pleasing and extremely effective.
This project took about two months and the cost was considerably more than I anticipated (it always ends up that way!).
There was ALOT of planning required for this project, which is why it was time intensive.
I made all the braided hoses at home with the Earls fittings, and you have to be VERY patient doing this type of work as the aluminum Earls fittings cross thread, scratch and gouge very easily, also you cannot overtighten them. So patience is a nessecity.
This set-up will easily cool 500hp so is more than adequate for my Turbo 20V. I even made provision for an oil thermostat, so that oil is not too cold especially when the weather temp is cool.
Well enough blabbing, here are all the parts and pieces before the install:
Here is a picture of the spin on adapter that goes to the block, I had these elbows hard welded for ease of access and convenience
Here is the inline oil thermostat with 1\2" NPT and #10 hose couplings
All fittings were 1/2" NPT or #10 AN ends, which are the same size the NASCAR teams use on their oil coolers. This is the size to go with if you do any type of long spirited driving (especially in 90+F summer temps) or have a moddified 4AG that you rec the crap out of. 3/8" / #8 will be OK as well for a NA engine.
Here is a pic of my new Oil Cooler:
I re-drilled the oil cooler to be able to mount it to my Honda Del Sol B16A radiator, this rad is a light weight twin core, all aluminum with a constantly running electric fan:
Here is the drilled radiator to mount the oil cooler, it was a fluke that the radiator and the oil cooler were almost identical widths, if it was not, I would be making more aluminum brackets!

I drilled my battery tray to mount the relocated oil filter
(Battery relocated to trunk)
Here is the spin on adapter mounted to the block, I had to drop the engine mounts to be able to turn and tighten this adapter and support the motor on a scissor jack - pain in the backside! You can see the wastegate flange in the top right of this picture. The other oil line in this photo is the oil feed for the turbo
Here is everthing mounted and tightened down, getting ready to check for leaks(In the picture below you can see my oil distribution block for the gauges)
I polished the intercooler while it was off the car:
Next to do is to hook up my oil pressure and temp gauges, I have a oil distribution block I custom made for this duty, and I will have that done very soon.
Hope that helps anyone contemplating such an install. Please note that you can do this install for less than half the cost, if you use brass fittings with barbed ends and regular black oil hose and hose clamps. Also having a turbo charged car increases the complexity of this install.

Horn 
With your setup Allan, the filter is down and out of view so the standard rubber hoses dont make things look ugly. With my turbo it sits up high and the lines stick out like dogs balls.

Mounting it up high sucks you will end up with oil everywhere when you change your filter, no mess and no fuss this way, not only that I want my engine bay to look nice and stock when Mr officer requests I pop the bonnet

If you worried about the heat from the turbo having an affect on the braided line dont be as i said no problems here, plus my braided line is pulled about 20-30mm away from the core of the turbo becuase of the fittings i need to put it on. This is the same in every case. As long as you dont use generic braid over rubber lines for fuel (cause it eats through that rubber after a while) then you should not have a problem. You would need proper braided FUEL LINE, it looks similar and probobly is the one used in the pictures pasted above.

Sorry I wasnt talking about the oil filter, I was talking about the water lines on my turbo. They stick out above the engine so using standard rubber hose will make it look like poo.

spends all that time and money on a 20v turbo conversion, and a horn looking\effective(or seemingly) oil cooler and the bloke cant even dish out for a trolly jack
i might be being unfair to the old scissor jack, but i just dont trust them....not at all(this comming from someone who used to change his oil with one side of the car propped up by a scissor jack and the rear on a slight down hill :/)

the hose temp rating is for its internal/fluid temp, and that'll just be your water temp. i think you'll have to get with the manufacturer for specs for its outside temp limits & working environment.
the metal braiding/mesh is for abrasion resistance and/or to increase the working pressure & burst strength, and is not a heat shield, thought it partially acts like one & must help some.

3/8" is -6AN not -8AN
