If this is for the BD4 it will have to be redone anyway.

Maybe Bob White would be interested in the idea below!

 How about a rectangular down pipe with a 90 degree twist?


Paul Lamar

Like always, just throwing out some thoughts aloud ( for the lack of hands
on possibilities, ...yet!)

I don't know how the arrangement of the evap cores will be, but Paul's 90
degree twist could probably be enhanced all the way into a horizontal
fishmouth across the lower rear edge of the engine bay or slightly below...!
If you get some ducting made from the backside of the evaps (...and for that
matter of the oil cooler as well), to match up with the fishmouth to use it
as an augmenter/extractor, to help pull air through the cores.
It is free for takes and if the exhaust helps pulling you can reduce the
intakes accordingly for drag reduction.......
Might not fit with a big radiator core across the bottom or the exhaustpipe
would have to be extended further aft of the radiator and its duct.
But for Bob and the evaps it should fit nearly below the whole engine
installation with some room left for ducting...

Did I miss something (except that I still didn't get started on
Rhino......)?

You got to get going on the Rhino 3D Tom so you can do scale 3D's of your ideas
to see if they fit :)
