Stainless steel intercooler pipe.

Is there a downside or any potential issues of using stainless steel for my intercooler charge pipe from turbo.

I run full 4" intercooler pipework which reduces into a small section of 3.5" to the turbo via a V-band flange.

The reason I ask is, I already have a 3.5" stainless v-band flange sitting in my toolbox so all I need to buy is the bit of pipe, instead of having to buy an alloy v-band and a pipe.

 

Cheers

There's no problem at all in using stainless steel for charge piping. The only disadvantage is that it's heavier.

And it's much harder to form a flange to it's end preventing hoses to slip off.

i normally just run a thick bead of weld around the ends to create that raised section to stop hoses pulling apart

Hi Tim

 

I also already did so. But first it's hard to melt a weld bed to the end of a thin cross section. And although @ my tuned diesel car the hoses always slipped of, 'til i took a hammer and forged a flange to each end rising 3mm at least.

are you using tig or mig?

 

when i did mine i Tig'd it using a 2mm wire and low heat, just enough to melt it onto the pipe over actually it bleeding away in the weld pool.

 

Another trick is if your having serious pressure holding problems is to weld 2 little boses, 1 on each pipe and then connect it with a bar that bolts into place. This means the silicone is just holding the air inside the pipe creating a seal and the metal bar is stopping them pulling away from each other and out of the silicone connector. Did this on some of the drag car setups on every silicone connection, never had a problem as we had same issues as you with hoses coming apart over 2.5bar of boost pressure.
