I was wondering if any of the turbo gurus can offer some insight on this for me; I've been pondering it for a while, but can't figure out if it would work or not.

One of my friends, who is a smart guy, was saying that he read an article saying that igniting unburned fuel at the end of the exhaust pipe can help keep the turbo spooled up during shifts, and other times that the throttle is closed. Is this true? If so, how does that work, and what's the best way to get it working? Inject fuel into the exhaust? Spark plug (rice!) in the exhaust? Extra fuel at low TPS readings?

I'm interested to hear some ideas on this one.

Thanks,
Stephen

 

Sounds like an Anti-Lag System to me. It's used in WRC. Also commonly known as a mis-firing system by Initial D freaks. Kills your engine! Do a search on google and you'll find plenty of info on it. I could be wrong.

 

As I understand it, it does not kill the engine so much as it does the turbo! (which may eventually kill your engine as well)

 

It will destroy your turbo. in WRC where they use titanium exhaust wheels, they have to be replaced after every race pretty much. That's the price you pay for wanting no lag

 

Damn straight.
