I've had alot of calls on how much hp gained from porting.Cannondale heads definately have big gains that can be made over stock.
On quads with stock modified airbox(included in porting) 7hp gain +-1hp
Quads with open filter setup 9hp gain +-1hp
Bike I've not dynoed yet but would say a 7hp gain+-1hp its definately a seat of the pants difference.
Dyno results have been extremely consistant.Look in dyno section to see hp per engine size and mods.
