Default Porsche intake manifold

Have read and watched some interesting articles on the Porsche intake manifold which would be relevant to our engines.

Keep in mind it's not a one size fits all in that you can pull the dimensions straight off the porsche piece and slap it on your EJ. There is a LOT of math involved to figure out ideal chamber dimensions, runner length, runner diameter and such.

While incredibly interesting I wonder if anyone who has made the expansion tank style intakes have run the numbers? In regards to Subaru aftermaket intake I know one dude who has run numbers on designs, but that's about it.

yeah I would have assumed that thing would have been super expensive bo to be able to get rid of all the piping and stuff should be as close to instant boost as possible

just fyi there is actually one for sale
