Direct Exhaust Induction

Has anyone tried direct exhaust induction before?

Ok. I didn't want to mention it but I was thinking about boosting the integra. 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 found a picture someone drew when they did it on their car, well rather its a sketch. but same principles apply:




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?

Ive heard about this and did some research before. Looks promising. Nick and i have discussions about it all the time. Hence his name Nick4dei.

Lmao, I saw this on Jalopnik earlier. It's like the 25lb of sand through the engine all over again.

To port and polish?
Yea dude, you mean you never done it? Just start your car, run your intake into a bag of sand, preferablly 25lbs of it, and rev that damn thing up. It will port everything all at once, so much easier then that old school dremel technique. When your done don't forget to hook the hose up and wash it all out ;)
