R&D continues at a rapid pace. This morning the Hyperflow guys took more measurements off my car and I left them with a spare OEM TMIC that Matt graciously loaned to us.
They weren't wrong about being able to "rapidly prototype" a new product. They plan to have the end tanks machined and a mock-up produced within the next day or so for test fitting.
Then we'll have to wait for around two weeks until the cores arrive from the US.
The cores are a good example of their attention to detail. Cores that use extruded pipes with integral internal fins are available here, but a core that uses the same fins on the inside that you see on the outside is more efficient, but not available in Aus. So we'll wait for the more efficient ones.
I'll post a photo of the mock-up soon.
