Now I don't know exsactly how presure drop works I would like to know if someone cares to exsplain. But in a overlooked theory of it, I would see the first pressurised air pass the chamber and drop do to exspansion. After this void space is filled and presurised back up, would this mean there is no more constant presur drop? Where the drop only accurs in the firsts instance of the pressurised air passing the void space?

Just kidding don't get your panties in a wad
Read about plenums and wave flow. Do a search on those two terms and you'll understand the properties of the plenum and what happens under "VACUUM" not pressure. There has been two threads on plenums lately that were very infromative.

Venturi's principle applies here. Larger diameters in tubing reduce the velocity of a given air flow within. So what we have here is a large change in intake velocities if the port matching isn't done well.

So you're theory would hold, except that the pressure inside an engine's intake is constantly changing.

The FD TPS is a full range TPS.. The s5 uses TWO TPS's.. one low range and one Full range.. I don't know how you would wire it in..
Also.. Keeping the stock computer means keeping the stock AFM.... Thus, the AFM is creating a restriction in flow that is counterproductive to doing the third gen UIM swap
99% of people who do this mod are also using a standalone.. I don't really see much point in doing it if you are keeping the stock ECU...

believe it or not.. each manifold is just a littel different, you can make an adapter to fit the stud pattern, but, to get the most out of it, you really should match all the runners together and smooth everything out..
Also I'm going to scrounge an s5 LIM so that I have one for fitment purposes.. This whole idea of shipping something out that matches the GASKETT.. is pretty un-nerving. I'd rather make sure it matches the LIM!!!
So yeah. gasketss would be included

I just wanted to prove that you can make them yourself, rather than paying some goon in Japan 350 bucks and then waiting three months for it to get here!!!!!

I ended up selling the Feed adapter and port matching the two manifolds and using aluminum filler rod on the inside of the primary runners of the lim to fill the void, smooth the transition and minimize ovaling of the runner (uses fd gasket). This is simply the best way to do it. The next best option is to use filler on the outside of the primary runners of the uim, nut this does not eliminate ovaling (uses fc gasket). Some day i'll do a write up.
Nice work btw

I took some time to test the fitment and mount the adaptor the other night. Everything went pretty smoothly, and nothing out of the ordinary. We will post up some pics shortly.
I'm doing this for the Flow, the space it creates, and looks. Gives much more space to work with compared to FC UIM's. Looks are much better, IMO, when comparing it to FC UIM's. With the design of the FD UIM the runners are longer and are said to have a better flow than FC UIM. Plus, I will need all the flow I can get with my setup

Problem is.. Most of us lunkheads.. Me included.. don't have the equipment to do that!!!

******'-A i want fd manifolds so badly...my friend and i were just talking about this exact same subject tonight. Only, we have a metal fabricator for a friend...that owns a shop, that likes to do custom projects on our cars so we can get word out for his shop. needless to say, its a nice resource to have. I knew it would improve flow, but i wasnt sure how restrictive the rest of the fc intake (aforementioned stock afm) would be. i dont have a stand alone ems either...now it seems sucky...maybe if the rtek2.0 comes out (lucky me with the s4 T-II) if they have it compatible with map, maybe a new project in the future?? anyway, looks damn good, cant wait to get the necessary flow upgrades for the fd mani's. damn those things are hot.
