[QUOTE="Posi, post: 15145461, member: 49592"] Here you go…and I "might" be putting my porting pictures back up soon in that thread. These pictures are from early on and they aren't what I sold as the finish inside it was better. You can see the porting though. I would recommend a 120 grit flap wheel for a 1/4" grinder to do your inside finish with and call it done. A smooth or mirror finish does nothing for power.

The male spots inside the plenum that are restricting flow can be cut down to less than what they are in height. To make sure you put a hole in the plenum you can simply use a wrench to tap on the plenum itself to hear when it's getting way to thin to cut on. I did that a lot and typically never broke through. If you do put a hole in it just clean it up good and put some JB Weld on it and you'll be good to go. [/QUOTE]
