Default Project Twin-Charge (turbo+supercharger)

***See my new, less ghetto build here:***
http://www.rs25.com/forums/f7/215008...running-5.html


Here's a quick video to give you an idea of what it sounds like: I'll get some better videos later.
1997 Subaru Outback: Twin Charged, 1st gear - YouTube


I though I'd start a new thread for this one, since it's different enough from the SC alone.

Everything is pretty much done, just tweaks here and there to make it daily-drivable.

List of stuff: (short)

Stock EJ25D (9.7:1)
Eaton M62 (from my old build)
JC Sports turbo kit w/TD04
CX FMIC
Emanage Ultimate
STi Yellows
E85/91 maps
Turbo XS RFL recirculated
Turbo XS knocklite
Exedy Stage 1 clutch
Lots of other things

Assembling everything:


Finally put together:





I'm running E85 with this setup, mostly as a safety factor until I can get it tuned up right.

The boost this setup produces is pretty insane, I've seen as high as 14 psi, even with a large boost leak. I picked up a Turbo XS knocklite to monitor knock, but I definitely won't be pushing anything until I figure out how to lower the boost.]

Emanage Ultimate, Innovate LC-1 wideband. I use the DIP switches on the front to switch between 91 OCT and E85 injection tables.

The same M62 I used in my old supercharger setup. That thread is still around somewhere.

I get about 19-20MPG on E85 around town, and about 23-24 on 91 in town. Highway is 26-28 depending in speed.

This still on a stock 2.2? Great work! Hats off to you sir!

Why have the turbo feed the supercharger and not the other way around though?

It's actually EJ25D, with newish short block. If you look closely, you'll see that this is actually a BG Legacy.

Reddevil, on NASIOC, was the inspiration for this type of plumbing, and after searching around and looking at other twin-charger setups, I found that this was a pretty common way to set it up. I don't fully understand the dynamics of it, but it works.
