Anyway, the tubes are now composite and go to the stock dynamic chamber

replacement to get some more weight out.
Dynamic chamber? Is that like a plenum? What does it look like? Do I need
one of these in a turbo system or does the intercooler do this job?

I think the dynamic chamber is a Mazda invention. Tracy is an advocate. Others say they aren't necessary for airplanes. I don't know but I'm retaining it for now. I have a complete '88 turbo engine out of a car on a test stand, it also has a dynamic chamber. It is located between the throttle and the tuned intake runners.
When I make the composite replacement I may try just a plenum first since that would be easier to build, then I will know if it is worse, the same, or better than a dynamic chamber.
