I've been following the various threads on HDF about the 120R. I am in the unhappy position of having a bike it won't fit, so I can envy the performance these things give, from the safety of the sidelines!
I've taken data from this Pro-Charged dyno curve and combined it with a dyno curve published in the Touring section, which makes for an interesting comparison. The red lines are for the Pro-Charged bike, solid lines are torque and dotted lines are HP. Essentially the Pro-charger comes into its own from around 5,000rpm.

interesting overlay. Where did you find the original 120r dyno you used? The procharger allows you to ride the motor like a regular 120r unmodified, untill you choose to put it up into the boost....then you ride it like a hayabusa......

There are several 120R threads in the Touring forum, it was one of several that have been posted. I must say that as a long-standing Harley owner the stock 120R, well tuned like the data here, would probably be enough. The thought of unleashing the super-charged one is mind-boggling!
John give me a call tuesday with a different cam and pulley and my dagula 2:1 220 hp is at your finger tips hint hint. It will bring your power higher right from 2000 to 6250 maybe 15/20
