Transmission shifting over 8500 rpms

[Tensecs2fame]

I know this is a problem our cars, especially on larger framed turbo builds. What if we were able to attach a magnetic particle brake to the transmission's exterior input shaft? It could be controlled via AEM to only work when the clutch is in

Heres where I'm thinking

Heres a video of the brake in action



EDIT: Ignore the time it takes for the brake to release, I'm sure theres alternatives out there
