All cars have egr systems on them now, not just the firebird.

To me all it looks like those high school kids have done is create an expansion chamber, which anyone can already buy and/or make. Sure, it's great that they did it, but it doesn't sound like anything revolutionary to me.

Wouldn't it be just as efficient to run a tube from the exaust to the intake, and then turn the a/f down slightly on the carb?
