I was just wondering how you port the inside of the runners? And how hard is it to do? Does anybody have any before and after pictures? Sorry if this has already been discussed but i did a search and found nothing.

<div class='quotetop'>QUOTE </div><div class='quotemain'>thanks for the pics, how'd you port it? Did you use a die grinder or the acid stuff?</div>
It was done with a dremel and some special long bits to get all the way inside.

Yes it can where there is a single valve. But when you have multiple valves you have the "hump" that begins the division of the air flow leading to the multi valves. Extrude honing will remove this hump. That may not be a bad thing if you are also porting the head and remove the hump on the head side. However that is not what I did so instead of having the airflow run smack into the face of the hump on the head side as others have done who have ported their IM, I left it in place so as to not add turbulance.

I would seriously caution anyone attempting to port and polish if they have never done it before. I would not "practice" on you IM or any other part of your engine. It takes some experience and skill to do it without f'n something up. That is why I had a friend who has lots of experience do it for me.

How much would it cost to have an OEM IM ported AND polished like that?
I saw the Extrude Hone website, but for $340 + Shipping, I'd prefer to spend the extra $200 and get an AirRam, I mean, I don't doubt Extrude Hone could be a great job on a IM, but it's so expensive that it get's the price too close to a professional-made sport intake mani with bigger plenum like an AirRam...
However, if a job like the one in the pics could be done for less than $200 (for the job itself, not including shipping) it could be a very good alternative... wouldn't it?
