I'd like to now this too.. What sets the redline in a turbo engine?

Also, 3rd turbo might be used to reduce lag.. I'm thinking of a very tiny turbo just to reduce lag..
The way 3 turbos can possibly work if the engine is an inline 6 and the exhaust firing sequence would match up with each turbo (2 exhaust outputs per 1 turbo), this would result in absolutely no turbo lag and an rpm line max anywhere BMW decides ( probably lower than M1 redline since power would come early.
Another scenario is a triple scroll turbo that basically does the same thing but much less power.
I doubt there will be a V6 scenario, since 3 turbos on a V6.. lol. No.
What ever it is, it will have good fuel economy and power across the band.
