REFLECTOR: Flexible intercooler ducts

[Scott Derrick]

I need to make a few flexible ducts for turbo to intercooler, servo to 
induction system.

redline MAP is 37 inches with a momentary 40 inch allowance, I believe 
the pop-off is set for 42 inches.

Thats about 21 PSI tops.

I had though about using racing quality silicon radiator hoses, which 
are rated to about 29 psi at 300 F.

I have also considered flexible stainless ducting, like the Cool-Flex 
product.  Anybody using this?    My concern with using a flexible metal 
ducting is work hardening form the engine movement?  Should I be concerned?

Any other ideas on how to do this?
