rubber intercooling bend sucking together

[greymatta]

I got a super six which I am trying to get running and I put a rubber bend on the intercooling and when it is running the bend sucks together I thought the air is forced through not sucked through so even if it is somehow blocked shouldn't it expand?????

No. This is common at idle or low engine speeds due to vacuum pressure, not boost pressure. How soft is the joiners you've used and how much are they sucking together?

I had the same problem on a SR20DET.. between the turbo and IC Piping (before the intercooler).. made it solid welded pipe - problem solved

Get some better silicon bends. Would hate to see how much they balloon under boost.

Pretty much flat

Yeah it was all welded and I had to modify it slightly and putting the rubber bend in was the quicker option but I thought there was something wrong for it to do that but if it's normal I will just re weld it cheers

The BYE boys have an internal metal bend that they put inside the silicon elbow.
