And I've heard the same.hellsing said:the misfiring system is kinda wierd, what i was told is that a sparkplug is place in the down pipe along with a fuel line
and when ever the blow off valve kicks in the fuel is shot into the down pipe igniting from the sparkplug and allowing the turbine to constantly spin so you have no turbo lag but thats just what i was told.
I know this. I was kidding....mostlyjeffg said:Basically anti lag is just a modification to you spark timing at off throttle.
The anti-lag system cuts spark when the throttle is closed but does not cut fuel. This allows unburnt fuel and air to enter the turbo manifold. When it comes into contact with the hot turbine blades of the turbo, it burns, causeing expanding gas and therefore keeps the turbo spooled up.
This is not something you want on a street car. It is incredably loud (backfires), and very hard on turbos. Ball bearing turbos will fail very quickly. The WRC guys run special thrust bearing packs in the center section of the turbo to keep them lasting the entire race. Even then, you wonder why the WRC turbos have quick disconnect oil lines.
