 I need to make a short flexible coupling tube that will connect the
intercooler in my car to the turbocharger intake tubing. I need an odd shape
elbow the is about 3" diameter on one end and 2.5 " on the other end, all
together about 5 inches long. I was considering using kevlar cloth wound over
a foam mold and bonded with two part polyurethane or silicone. The
construction method would be as if I was making a rigid structure out of
fiberglass but since it needs to be somewhat flexible I do not know what
materials to use. The maximum air temperature that the turbo spits out could
be close to 300°F There will also be some oil in the air. The tube has to
withstand internal pressure of up to 35 psi transient. Normal internal
pressure is up to 20 psi. Any suggestions will be appreciated.
