I don't know what Hogan uses, but I would expect them to be at the top of the game when it comes to the epoxy they use. I have seen there intakes start to lose epoxy after only 3-4 dyno pulls. I think its the mismatching of materials that causes the issues more than anything in the lump situation. I agree, a lump made from the epoxy material completely might be a better solution if you are going to use epoxy at all.
