[QUOTE="TurboX2, post: 14895098, member: 60153"] Unless he asked for a max effort race port there's a very definite limit to how much time and effort is beneficial and cost effective on a thin wall plastic intake where you can't reach most of it anyway. An experienced porter at a race shop should be done in an hour or two with a quick cleanup to the ends of the runners and t.b. inlet. Those who spend hours polishing things to a 'perfect' finish don't understand that the air doesn't care about pretty and there is a boundary layer of air in the walls of a runner that doesn't really flow, so that mirror finish does nothing for performance over just smooth. There's also a huge difference between doing it the first time where you are feeling out the process, and someone who does it for a living and knows exactly what to do and is efficient about it. My own opinion is that doing it yourself or paying ~$150 or so is cost effective, for $450 difference you could have a Cobra Jet setup instead that will make as much power (or more than) the ported Boss and has more potential.
