Damn, i wonder what BMW would have used in a situation like that, but then again - naturally aspirated engines... no forced induction
Yeah so when building the intake track for my supercharger (charged air from blower to the throttle body..) i used an Audi S4 biturbo upper intake boot. Reason being that it was molded the shape I needed, it had a built in integrated diverter valve vein and was reinforced.
All is true, EXCEPT, it's NOT reinforced silicone. It's shitty rubber. The Biturbos are making like 8psi stock between two turbos... I guess the load isn't as great as 9 psi supercharged. The hose burst right at the joint. I coated it in silicone so i could limp it back to school sunday night. It got me to school (huge huge huge vacuum adn boost leak). Threw CEL (maf sensor misread, 1215) all the way out, got like 8mpg for 60 miles because of this damned boot. So yeah, that's right, F- You AUDI S4!
I made a new one out of MIG welded steel. I will post pics tomorrow. Works much better, and MUCH stronger!

I can't wait to see the steel one. Good job flipping off the boot, by the way
Obvious difference to me is that it was designed to be 'sucked through' on a bi-turbo ... your words read as if you are using it to 'blow through' with a super .. so failure probably predictable ?

Seems like I remember from my Audi days that that's one of the first things they change out, I guess you know why. I think there's far better aftermarket ones.
Yeah, they're $129 for just that hose from Samco, the full kit is over $400

9psi isn't much for a rubber hose.
Was it second-hand? Given that it failed at the clamp-zone, it could have blown due to heat/age or more likely a pre-existing injury (being pulled off at a wrecker).
Alternatively, your charger might create larger peak pressures than the stock A4 setup. These wouldn't be necessarily reported on your gauge... I imagine it irons out the shorter peaks efficiently.

Oh well, you'll be much better off with your newer, stronger part.
