More towing power??
All you'd really need for a blower is an exhaust with more flow. That, and I'd recommend a dyno tune, though I'm sure the supporting vendors also have good tunes.
And depending on the blower you get, maybe gears.
I re-geared for my blower (wish I had done it a lot sooner) because with 3.31 gears, my RPM were too low, as centrifugal blowers need revs to make boost, more so than roots-type or twin-screw blowers.
