this i know.i was just asking who new the 8ab's w/ power-inc pipes.i looked in the tech-sectoin & there's no info.just the 89L's w/ power-inc.thanks thowe
Try it. Might be right on the money. Need snow to really test though. Still trying to sort out a set of drag and flys here but only took 3 months to get the helix in from dalton.
center dump pipes are real low rpm, its the end dump ones that are the higher rpm. Theres a good bit of info on the pipes here youll just have to use the search option on power inc pipes.
Dont expect alot with the center dump pipes

.we will have to give a shot.i guess the wight's are 49'grm's.what about bigger rollers will bring the R's down to 8100?.& thanks again.

bigger rollers add rpm to both engagement and shift speed. To lower the rpm youd need to use a softer primary spring if you dont want to add weight to the clutch arms.
