So seriously, if you don’t follow this guy on at least one of your social media accounts, you can’t really call yourself a ‘car fan.’ I don’t believe in litmus test politics, but that’s my litmus test.

So anyway, this piece of automotive porn appears on my feed.

behold the V-12 Peugoet V-12 HDi FAP fap fap fap. For those who don’t recall, this was a rocket ship when it appeared. Low outboard turbos, short-line intercooler plumbing it had it all. And those swirling things.

Speaking of, what is the goal of those swirling things? Disturbance versus flow? I can’t recall seeing anything outside of a laser copier toner drum shaped like that.

I imagine it is to help with airflow in some way. Doubt Peugeot would ever tell you.

Maybe it is to direct a portion of the air into the inlet ports, seeing there are 12 swirling things, and 12 cylinders.

I agree it helps, but how.

They’re probably just a marketing gimmick.

Not really sure about the swirls, since you don’t need them for mixing. Also, all of your tumble / swirl going into the chamber is caused by the intake port shape. Only thing I can think of is they are actually longer runners internally that you can’t see in the picture.
