I find that for the throttle body plenum it works very well. You suspend
silicon rubber cores (I cast mine in bent tubing) in the plenum body void and
then pour in the polyurethane - it hardens in about 15 minute or less. you
pull out the silicone rubber cores and I use a hole saw to cut through from
the TB mounting surface to the tunnels left by the silicone cores, a few
inserts to take the bolt loads and I'm done.
