just found this on my search for an osir carbon rear valance, but has anyone got these, do they help ? this place thinks they will add 5-7 bhp. also they have engine dog bone mounts, does anyone have them? and again do they help ?

pullys don't add hp they just make it more readily available. It's like putting in a lightened flywheel. the HP number is still the same but it gets the wheels faster
