i tried porting the throttle bodies on the 998. they arent real smooth as they taper down from the inlet to the outlet so i blended out the sharp steps and opened up both ends by 1mm.
on the flow bench, they went from 145 cfm at 15" to 157 cfm. that is per throttle body.
i'll be putting a set on the dyno soon for a direct comparison but i am pretty confident that it will add a small amount of power.
