Eric, you must elaborate on this. Are we talking about 2 injectors per cylinder?

Eric has a custom Forrester intake manifold for his (I'll let him tell his details). Keeps idle nice while being able to provide gobs of fuel because bigger injectors make idle fine tuning hard. This eliminates that, while being able to provide the right amount of fuel when using a monster turbo. The AEM EMS makes adding 4 extra injectors very simple to do.

Here is the Magnus model...

And here is another one. Not sure what Erich (different Erich) is using here, but it sure is pretty.

Wow, that Magnus one looks awfully crude, the injectors are pretty far up and don't look like they are aimed very well. Is your car acually running with two banks Erik?

Hehe...not running yet, but it sure does look cool! :D

I don't have any pics with me here at work, but I'll see about uploading some from home.

Sharp eye, Jon! :cool:

These aren't the best pics, but here's one (http://co.dsm.org/forums/vbpicgallery.php?do=big&p=72) and here's another (http://co.dsm.org/forums/vbpicgallery.php?do=big&p=73). The setup has changed a fair amount since then (COP, no strut bar, etc.), but I don't have any more recent pics unfortunately.

Wow, that looks killer! Them are some big lines :) Do they tee back together before the FPR or are you running 2?

The lines to each rail are only -6AN; I figure that's sufficient for whatever injectors I end up running in the long run (certainly enough for the 450s!).

It's hard to tell from the picture, but the lines 'Y' out of the fuel filter into each rail, and then enter the FPR from opposite sides (one FPR, single return line).

I took a few updated pics this weekend:

One (http://co.dsm.org/forums/vbpicgallery.php?do=big&p=81)
Two (http://co.dsm.org/forums/vbpicgallery.php?do=big&p=82)
Three (http://co.dsm.org/forums/vbpicgallery.php?do=big&p=83)

Still more clutter than I'd like, but at least the COP makes it a bit cleaner.
