i wasnt too sure if this is a repost or even possible but just wondering if anyone had any views on if porting the intake was possible and if there are any gains in hp from doing it.

has anyone done this? or see any tech articles about doing this??

you can't port plastic there homie, now if you are talking about the plenum then yes you can port them, don't know if its really worth the effort cause it won't gain you that much.

ya i know you can port the plenum and the TB for like a awesome 2hp. but i wasnt sure if that plastic one could be or not. i figured maybe if it was thicker then maybe but i guess not.

yaaa and the worst part about having those plastic intakes is when they crack. screwed me over, and i didnt have the money to buy one like the typhoon.

What about porting my stock manifol? Do you think that would be good for me to do?

The main problem with the stock intake is not the size of the runners, but the length and shape of them. Factory manifolds are designed for good drivability and emissions at all rpms. So even if you could port it you wouldn't notice much. I recently picked up a used typhoon on ebay for $400 and spent 2 hours porting and polishing it. Should make some nice HP for not a lot of money.

Well I found this after I asked the question:

http://www.musclemustangfastfords.co...bullittintake/
Bullitt Blast Performance enthusiasts know one way to increase power is to improve the airflow to the engine. If you own a 4.6 2V, it means installing an '01 Bullitt intake manifold. Unlike the plastic intakes found on all '96-present GT models, the '01 Bullitt manifold is cast aluminum which gives it some advantages--first, because it can be ported, and second, because if you run nitrous, there is a much smaller chance of blowing the thing into a million pieces should your engine encounter a dreaded nitrous backfire. Another attribute is the shorter, yet larger, runners. If there is a downside, it is the weight. The Bullitt intake weighs about 35 pounds, which is about twice the weight of the plastic one.

I've heard mixed reports, everyone wants to try out all these new intakes, but how much hp can they actually put out?

Hell, I port matched my stock (plastic PI) intake with some router bits made for wood just to even up the entry into the ported heads. I don't know if it really mad a difference, but it inly took about 30 minutes. Just be careful not to get in there to deep. That plastic comes off fast.
