considering that this manifolds uses the stock runners (as do Rons) how much different could my manifolds numbers be from Rons, providing of course that I have a smooth transition from the plenum to the runners (which I do) We all know that the factory design is easy to improve on from a performance standpoint, not mention cosmeticly. So it stands to reason that this manifold will do wonders of improvement. All the key ingredients to a high performing manifold are here in my manifold. As I have mentioned before, in a perfect world, I would make the 7M manifold with straight runners and velocity stacks protruding into the plenum. But givin' space restrictions, its next to impossible. For risk of another discustion about this, I'll say this now, its pretty well known by those who know this stuff well, the runners furthest away from the throttle body get less air flow (scavanging) There is little that can be done about this, so we do what we can by increasing plenum volume, to make the air more plentiful, and tapering the plenum to hopefully increase velocity to the back cylinders, and of course make the transition from plenum to runners as smooth as possible. All things that are part of my manifold design. Wow, that was a mouthful, sorry.
The runners farthest from the tb or at the end of the plenum tend to get more airflow, not less.
Nice looking manifold, BTW.

Just to give ya a pointer if you use a thicker base you can make nice ports much easier. Like this:
As for the straight off the header I have a setup with velocity stacks that I am working on, search on SF for a post about velocity stacks internally there is a very interesting post about it! Mine will actually be having fully custom built runner that come up to a 90 and sit the housing upright but or I may actually go almost 180 to make the runners longer! But that will come down the road. As well you do not have to go so far outside the box to not copy someone. A manifold like this I recently built is something new in that it retains alternator and A/C but is the short runner tappered design. This is something different from anyone esle yet combines a lot of ideas from others:
You will amaze yourself with the ideas you can come up with by having input and ideas from others and then putting your own flair on it!! Best of luck, let me know if you have any questions or and I got a proposition for you about the Alt Brackets!

I've got a lot of ideas for FFIM's as well, this was just one that I thought of, made, and was happy with. I've got an idea for one thats pretty wild, way different from any conventional designs. I don't own an MK3 myself anymore, so I just have limited interest on how far I wanna go with these. I don't want to spend a bunch of time and money just to show off, and have something for people to google at. Be careful with the runner length and bends, if you are going for a torque monster it should work out well, but you might loose some HP on the top end. Its really cool that we can all gather here and chat about this stuff. I love the useful input. If we all put our heads together on one project, we could have a truly amazing outcome. Keep up the good work Seth.
P.S. hit me up via PM on your propsition on the brackets.

means a lot coming from the man himself! thanks Ron, and thanks for the correction as well.
Seth, here is one I did for a Honda, the intire runner is a true velocity stack, not just added to the end of the port. Could do something like this for the 7M but not sure if there would be enough room back there? But still have my other top secret idea for a future build.

Where do you live? I've got my connections here in Oregon, but wouldn't do you any good unless you're local. Most any machine/fab shops could sell it to you, or any place that sells steel, hell even a welding supply store could send you in the right dirrection.

www.Onlinemetals.com is decent but I have never really searched it out. Of course I live in Washington which is where they are so shipping is reasonable! HTH

Very cool Man,
Mine is going to be upright to allow for alternator kept in place just lowered. But that thing would be wicked.
