Well... The news is: there is not any.
I was sent yet another prototype quite a while ago, which is quite suitable for production IMHO and solves the problems I discovered. It is still on my car.
I also sent back 6 other complete induction kits that all showed the de-lamination problem.
Since then all attempts to contact SAMCO / Sillflex about this matter failed.
I've spent literally weeks on this groupbuy now without buying myself

!
Status now:
1. There is an alternative prototype @ Sillflex that would be a proper solution for everybody who obtained the
turbo induction hose.
2. At least 6 people are now without their induction kit, and without any refund
3. I did not get the promised refund to cover the international shipping costs either
4. There is one owner
(luckily only one as i reacted fast enough i hope!!!) with turbo, intercooler and more damage, caused by the delamination of the hose.
5. None (none!) of the attempts to get the general manager of Silflex on the phone succeeded.
6. The limit of my patience and politeness and spare free time is now reached. If i do not hear from Sillflex by the end of next week, i will investigate in serious alternative steps that I can take.
I understand this is not the news we were waiting for. Let's wait until the end of next week to see what we can do.
Who knows, perhaps a miracle happens and Sillflex will come up with a solution that we all are waiting for!
