What I am trying to get at is....it's very likely that this is only a little piece of something that is much bigger and more expensive so some may want to strap on their seatbelts to know that the whole system is thousands, excluding the mechanical work (if they cant' do it themselves). Not tyring to be a "downer" at all...just want to get a bit of a clearer picture.

In another thread, Richard posted a dyno shoot showing 25hp and 13lb/ft gain at the wheels
