yoeddynz Posted December 22, 2010 Share Posted December 22, 2010 I need two 50mm ID 90 degree bends to route my output from the turbo to the inlet manifold. I was thinking I could use radiator hose but as its a fuel charged mix, not just air, this could be a bit dodgy if I had a back fire etc. I went to super cheap (oooohhhhh the shame it it all) but all the silicone hoses are blue- I aint wearing that! I want black. Can I use rad hose? Any ideas? this is the setup.. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted December 22, 2010 Share Posted December 22, 2010 A radiator hose is designed to handle 15psi of water pressure with a generous safety margin on top of that so the handling of the pressure should be OK (you setup looks reasonably low pressure) The problem would be its solvent resistance.. If you are willing to carry a spare hose for when it does eventually shits itself then I say go for it and change hose when it does. At least you will be able to report back to OS on the longevity of water hose resistance to petroleum based products.. I reckon it would last a good 6 months to a year of moderately regular use.. perhaps even longer.. My reference is how radiator and heater hoses turn to jelly after a couple years of engine oil leaking on them.. Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted December 22, 2010 Share Posted December 22, 2010 you can get black IC pipes, look on tardme Ive always found it very difficult to get radiator pipe in the correct shape without kinking it which it doesnt seem to like.

mjrstar Posted December 22, 2010 Share Posted December 22, 2010 I reckon an evo 4 up turbo outlet hose MIGHT work in that spot. It should be easy enough to find one pretty cheaply, sadly my google skills atr too shithouse to find you a picture of the hose i'm talking about... I'd steer clear of the rad hose if at all possible..I'd say it would only a matter of time before it turns to cheese... EDIT.. Go trademe..

efp0wa Posted December 22, 2010 Share Posted December 22, 2010 Go to a truck wreckers and get some black indution hose bends? Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted December 23, 2010 Author Share Posted December 23, 2010 cool- cheers. Those black ones are ideal....but.... this is the budget build. I'll need two bends I think and its hard to stomach spending $80 on two bits of pipe. It is so easy to access and remove the bends I reckon i'll try rad hose first- maybe take them off every so often to check if they are going cheesy. Trouble is 50mm is quite big hose for a radiator? That evo setup looks like it could have bits that could be bodged to work. I'll try local wreckers and see what bits they have as well. what is the material that OE manufacturers use on cars? is it some blend halfway between silicone and radiator hose material?

Raizer Posted December 23, 2010 Share Posted December 23, 2010 Try a tractor place for tractor radiator hose, should be able to get 50mm stuff and its pretty cheap (well the 2.5" stuff I used on my old Subaru's intercooler piping was at least) Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted December 23, 2010 Share Posted December 23, 2010 rad hose is pretty fuel resistant but some cheaper silicone pipe will melt with the fuel. ive been using rad hose for my bike carbs for quite a while, hasnt gone hard or soft yet Quote Link to comment Share on other sites More sharing options...

fuel Posted December 23, 2010 Share Posted December 23, 2010 I use rad hoses for the soft pipes on my intercooler piping on the Eterna/Galant GT, but mind you they probably don't have to deal with fuel vapour, only oil pissing beyond the turbo seals haha.

drftnmaz Posted December 23, 2010 Share Posted December 23, 2010 if you put a rubber hose there it will collapse under vacuum cause its a suck-tho setup, so has high vacuum between the throttle and the inlet, it will expand again under boost but looks dodgy when you open the hood and see a hose all sucked in... it never stopped mine from working but i changed as soon as i saw it much better to make a metal pipe from offcuts and use a small piece of straight hose on each end. and yea truck/tractor rad hose is normally available in some pretty tough black stuff that looks like proper intercooler stuff Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted December 23, 2010 Author Share Posted December 23, 2010 rad hose it is then! I wasn't going to do the whole section in hose- just two bits at each end of a piece of tube. Tractor place- good idea as plenty of them about here is sunny hicksville. Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted December 25, 2010 Share Posted December 25, 2010 can get rad hose with a coil inside it too so it wont collapse (as much) Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted December 25, 2010 Author Share Posted December 25, 2010 all sorted now- made a steel pipe out of welders bends - simple, cheap, smooth, heavy.. Just need one more little hose join - will use a short section of rad hose. Quote Link to comment Share on other sites More sharing options...

yoeddynz Posted January 3, 2011 Author Share Posted January 3, 2011 oh yeah- heres what I built... No photos of it inplace as I have not mounted inlet manifold back in place. I need a sheet of gasket card - 1mm thick ish. Any recommendations on where to get? needs to be at least 280mm wide. Quote Link to comment Share on other sites More sharing options...
