That's interesting higgi. Any chance we can get closeups of the auxiliary ports?

 

NZ,

 

Insides ? I will try to take better pictures tomorrow

 

I'm very interested in this setup for exactly the reason Blue TII describes. I'm not sure if the flow characteristics of the Euro LIM are good enough or if I really need to be looking at a custom LIM. That's why I really want to get my hands on one to study and, if necessary, modify to suit. I would like to run an aggressively ported aux port with a set of Euro endplates or, more likely, a set of US endplates with a fixed insert to give the end of the runner a nice radius.
So, anyone got a spare Euro LIM?

 

If you're going that far with the secondary and auxiliary ports then you're also going to need to enlargen the LIM runners to port-match them. This would require custom larger butterfly valves in the auxiliary runners. So this isn't as simple as it sounds.

You guys are assuming that the butterfly valves are superior to the rotating sleeves, yet not a single person can offer even a shred of proof either way. From the pics I've seen, I seen no obvious flow advantage.

I think some of the people interested in going to the butterflies are interested in doing so in order to monster port the Aux. port or add a bridge to it in which the rotating sleeve becomes difficult to incorporate.

Need a new LIM to optimize this, but you could have a streetable 6 port that was a monster on the top end.

LIM is for lower intake manifold I envision a fully divided 6 runner manifold system like the Rennisis working the best. After modding my intake manifolds I think it is actually probably easier to just make your own instead of working w/ stock pieces.

 

Yeah, I know what LIM means..

But the butterflies are in the LIM, so if you need a whole new custom one, then there not much point in getting a Euro LIM, which was the whole point of the thread.

 

Yes, we agree that a new LIM would be needed to optimize a wild aux port set-up and the thread title is about butterfly conversion, but there is no reason we shouldn't discuss alternate butterfly conversions. Besides, how many people optimize their set-ups?

Higgi posted a pic of the irons and members asked for a more detailed view of that- it was obvious to me they wanted to see the champher of the aux port back wall as the 6-port style is a 90 deg dead end.

Anyways, hopefully our banter will keep this thread toward the top so Higgi can find it and insert those detailed pics...

 

Worse than a simple 90 degree dead-end, the end of the US-spec aux port is a recessed dead-end with the rotating sleeve installed. It's pretty deep with the sleeve removed...
The pics that Kim posted looked like they showed the end of the Euro aux port pretty well. It looks like a pretty nice radius! However, I'm not convinced that it would be easier to get Euro-spec irons in the US than it would be to remove the rotating sleeve and make an insert to give the end of the port a nice radius.
Could one of our European friends post the diameter of the aux port opening of the euro LIM? I'm not really getting a sense of scale from the pics, and I think that being able to compare diameters would really help.

 

which by FE i assmue you mean SE....

 

 

FE=RX8

 

In Europe RX-8 is SE

 

do you know where to get one of these for the second gens?
