Aluminum vs. fiberglass? Anyone made one similar to Diamond Aircraft's two-part plenum? Reason for change--running ok except hot weather CHTs go to 425+ on a couple cylinders despite injector sizing changes on my IO-540 with Lasar and proper baffling. Please no comments on the IO-540--I just like excess power! Don Schmiesing Seattle 110 hours on 417DS
