With the SS rated at 173 HP, I assume that's at the crank. Lucky to get 160 at rear wheel stock. Bump that 50/65 HP, that's about all you can get to the ground without feathering the throttle if running the twistys. It will make hard line acceleration up to 60 MPH at the edge of breaking loose or possibly breaking loose. The large number HP would be fun at 90 MPH and then hitting it, but that's usually about the fastest I tend to go on a regular basis. Most of my riding is 0-80.... even 0-65 honestly. 225 RWHP would be likely all the fun I'd need to keep me happy, and could be done keeping reliability.
If DDMWorks pursues in this direction, put me on the list of wanting it.
As i said before Turbo/SC have no appeal to me due to my driving style but if DDM were to do something like this and improve the NA crowd i would do it in a heartbeat as well.
