Pics to follow in multiple emails,
due to list size limits.
I bought most of my stuff from
http://www.siliconeintakes.com/
and
http://www.verociousmotorsports.com/
Also, check ebay for both mandrel bends and silicone bends.
There are several sites with pretty good prices.
Silicone Intakes' mandrel bends are much cheaper than their
silicone bends. For same-size couplers, you can just buy a
length of hose & cut it into couplers (see radiator input
pic).
I had no luck bending thinwall AL tubing myself, even if I
packed the tubing with sand prior to bending & used a Harbor
Freight hydraulic pipe bender. However, if you can stand the
loss of flow area, AL electrical conduit is relatively easy to
bend without collapsing it (thicker walls).
Silicone hose seems to cost anywhere from $5 (1") to $20 per
foot. Tubing looks prettier, but a continuous run of silicone
hose isn't that much more expensive and it can get done in
minutes instead of weeks. Ask me how I know....
