slinges

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

What youre buddy said is not true.

Igniting unburnt fuel in the turbine housing can keep a turbo spooled at the cost of very short turbo life. WRC teams have systems like that equipped on their cars.

But lighting fuel at the end of your exhaust has no practical purpose.
