I did indeed visit Ramair on Monday and work on the one piece filter is progressing although running a bit late. I was shown the computer model and they have followed the basic shape I gave them. Latest is that the tooling will be ready early next week and hopefully a prototype will follow a few days after.
The replacement bear-claw mentioned is also not intended to be a power producer. The idea was not to act as an air ram but just allow cooler air to the filter, and look good of course.
