blowoff valve questions

[Dave Eaton]

a lot of the rally cars blow flame because they are dumping raw fuel into
the turbo using a special injector.  this keeps the turbo spinning - called
an anti-lag system.  usually accompanied by a machine-gun-like sound.

Ok -that is possible, but in my opinion ( and the local rally people too )
mass
and energy of that routed air makes it only theoretical? So You can see all
WRC and smaller cars blowing fire, because of the rich mixture in pipe.
That small blow spools turbo while the B/P is open out and the throttle
closed.
Also there is something rich allready, when the throttle again opens...
