bro,
may i know the setting of the adj. cam pulley? afraid that is setting for pick-up, not for top speed. nice mod u have there.
or myb u can try to clean the carburator.
or, change open pod filter
yup, might be the adj cam pulley is set for pick up which surely will sacrifice your to speed...another thing is your rear mufler, is it straight flow or 's' flow coz this also afect pick up and top speed..however, looking at your dyno sheet, u might need to tune (lean a bit) your fuel regulator to gain better top speed as well....(don't forget to use lighter 15" rim) huhu
to all sifu's out there..
Im asking this question on behalf of my brother. is there any subaru specialist in sunway that is capable in doing anything, (modification, repairs, etc.) to an impreza?
