The most mysterious Anti-Lag System Uncovered - Renault's DPV

Donut media made a video about Turbo ANTI-LAG & how it works, but here is one you've never heard about - the Dispositif Pre*rotation Variable - or short "DPV" engineered by Renault's engine genius Jean Pierre Boudy.
It's a very clever way to spool up a turbocharger, maybe just as clever as the Subaru “Jet Engine” - Rocket Anti-Lag - but with less flames, much older and based on the Russian Swirl Throttle.

"Forced Induction Performance Tuning" by A. Graham Bell

In case I've missed to credit someone or something in the video, let me know and I'll add it here.
