He made the intake for the RP968 as well.. Real class work!

Yes, most definitely!

I designed a 16v intake along with fuel rail etc. Not as fancy as a fully CNC-machined intake but with great care taken to the dimension of the full radius bellmounths, runner length etc to maximize power. I'd say it's race proven with 672 rwhp at 1.5 bar
We had several made, I have one left for sale.

Results speak for themselves. You have an esteemed admirer for this. :-)

Duke,
nice piece!
Do you know if the injector holes are drilled at any angle, or are they vertical (perpendicular to the flange)?
I have another 4v intake here and they seem to be about vertical...

Duke:
Can that intake work with the factory 968 MAF or do you have to use a standalone (eg VEMS)? And will sanding down the welds compromise the strength of the intake? I am interested for my 968.
Thanks

There are two parts to this - bell mouths and stacks.
The length of the stack is critical to the RPM range you want to maximize. Is a resonance circuit that is tuned to a particular frequency.
The Bellmouth is there to try and impedance match the runner to the plenum for less resistance (OK - i'm using that term non-technically!).
You can play with both to get what you want!

You'll never find a conclusive answer but the general idea is that stacks sticking into the plenum are to get a desired overall runner length while short on plenum packaging space (can't move the plenum 2" to the right but you can make the runners stick 2" into the plenum).
And idealized bellmouths can pull air around 180* from the entrance point (from "behind" the bellmouth) which wouldn't be possible with a flush stack.
I made my 16v intake with stacks into the plenum more for construction reasons.
