Thread: Intercooler hi pressure side Elbow?

It may, the softness may be ok, but one consideration could be that it shows age coming on and with that there is the increased chance of delamination in the layers of the rubber. The inner layer can lift if torn, or balloon if pin holed and effectually plugging the hole(this is often described as being sucked in, they may be talking about this). The ballooning can be very frustrating in that your first couple of inspections it may be hard to pick up.

Soft hose's regardless of delamination are discussed by racers etc who are chasing splits of a second... if the rubber swells on boost you are technically wasting time and energy pumping up rubber,,, instead of burning rubber.

In our case if the rubber has become soft enough to suffer any real swelling, it will eventually place enough stress on the cohesion of layers, that may lead to blockage.

I think a lot of people change the hose when they detect sponge... Contact Dullbird (I think) she was selling some silicon hose, which is a popular way to go (I think...again TIC)

If you're going to replace your turbo elbow, try pricing a silicone version - mine's holding up well after 2 years:



ps: you might need to trim it a bit.

Great thanks for info Duff, some are asking around the $160-$180 mark for two hose's , call me tight if you like but I cant see the value there.

But I have a young mate I know through work who has been in the hot 4 game playing with mods on wrx, evo's etc and he has a heap of stock left over from when he had a workshop, so I might get lucky in getting a cheap elbow , not sure about the top longer hose though, but it isnt any where near as soft as the elbow.....

Cheers langy, thanks for pic, are the clamps called "T" clamps? where you able to sorce the other top hose aswell?

Any one know the size of the elbow hose (diam) off the top of their head.

51mm (2")

and FWIW I prefer SFS or Samco hoses. They generally have more (4 ??) layers of braid than the cheaper silicone ones so cope with higher pressures better.

Suggest that you contact Mike (Tombraider) on this forum re silicon hoses. I bought some off him about 6 months ago to fit the TD5 turbo and intercooler.
