Les, what are the measurements on yours? Primary diameter, primary length and collector diameter? From what I understand the primary diameter with 75% volumetric efficiency should be smaller than our port size which is 1.5"... It sounds crazy but anything much bigger than 1.5" is loss.

Solid would probably do better too, I like the hoseclamps but maybe my welder can bracket the shield, fixed, just above the primaries with little contact... That way the clamp isn't touching the pipes as much, transferring all of the heat to the shield.
