You can't just slap a blower on it, come on.
TTS has to develop a package for the 961, just as they did for the Thaiumph.
The Thaiumph kit comes with lower compression pistons and a different cam than the stocker.
There are probably other changes as well like ignition timing, etc,
That's why an experienced team has to develop the kit.
I sold off my R&D facility years ago.
I would say 6lbs boost should be good for 100hp or close to it.
The only issues I would be concerned about:
1. The bike would have to have a "fixed"clutch basket.
2. Given the few balancer failures, I would have it magnafluxed for cracks, then tuftrided.
I think the crank, and gearbox will have no problems handling 6lbs boost.
