9whp being the max seen.
but there is more than just boring out to 62.5mm
the shaft was cut in half and the arrow edged the butterfly plate
im pretty sure there is a picture in one of my album here.
edit; to see the true power potential of this mod , the intake tube,specificaly the MAF tube has to be bigger than stock to maximize the Hp gain.
the OEM MAF tube size is 60mm with the big MAF sensor in there so there is a restriction ,,, the MAF section has to be able to flow more than what it is at the TB to see the result.
