    I'd like to introduce you to DEI (direct exhaust injection)

    Alright, this guy is pretty stupid, but..... just read this:

    Ok. I didn't want to mention it but I was thinking about turbo charging my Vette. I got to thinking about it and how in efficient even turbos are (compressor efficiencies of about 80% at best).

    Since a turbo's function is to pressurize incoming air and force it into the upper motor, and turbos are driven by high pressure exhaust gas created from the combustion process, couldn't I just bypass the turbo altogether and route my headers back into the throttle bodies?

    Since I have CFI, I could balance the DEI (direct exhaust injection as I just coined it) by feeding one header into each throttle body. Yes, the charge air wouldn’t be that cold, but it would be under a hell of a lot more pressure.

    I attached a quick sketch below:



    There are still a few things I need to work out:
    1) How do I get the CFI aircleaner to fit in a way that hides this plumbing?
    2) Does anyone make a V-band clamp that will bolt an exhaust header to a CFI throttle body?
    3) What pinion angle should I use in my rear-end? I’m sure there will be a noticeable difference in torque output.

    What do you guys think?
    His replies are great too:

    agreed. This is absolutly rediculous. I wonder what these guys are thinking when they come up with stuff like this.

    Well, it is Nebraska...

    This is such a bad idea, there is no control over the reaction, you could have unlimited power.

    Kind of like pluging an extension cord back into it's self, your going to blow shit up, don't mess with stuff like this.

    Where does the intercooler and Blow-off valves go? Also what about the wastegate, you have to control boost some how?

    Not only an idiot, but look at his signature: his Corvette does 15.2 in the quarter mile? My car will do mid 14's all day!

    Yeah if I had a Corvette that was that slow I'd be pretty desperate for more speed too. But wow! This is the automotive equivalent of eating your own poo.

    IT IS BRILLIANT

    Have i really understood what this guy is REALLY on about ?

    He is trying to feed the waste gases back into the engine, like a straight pipe into the air intake ?
