East Coast Supercharging Twin Turbo Build
All of the details and the backstory on this build will be set forth further below in another post. Too much to write and I still need Alex to send me all the photos from the build.
After finishing (another) the season with the same old build (Stock LS2, ECS Paxton 1500, ECS Cam, ECS Stage 1 Fuel System, Kooks headers and mid pipe, Z06 exhaust (with Mild to Wild), RPM Level 7 TR6060 (regular ratios 1 - 4, ZR1 5th and 6th), ECS Trans Brace, CF driveshaft, Mantic 9000 twin disc clutch, MGW Short Throw Shifter, RPM Stage 4 ZR1 Differential, and many and other supporting bits and pieces, while at the Slipstream Racing Events driver's dinner the night before a roll race event, Doug and I started talking about getting a little "more" out of the current setup. By the time the dinner conversation was over, we agreed that all of the stuff in front of the torque tube had to go and that we were going to build a front mount twin turbo set up for the car. I am sure that there were some times over the days leading up to today that Doug wished he sat at another table. I know Chris (and probably Alex) wished he did..........
After Alex, Doug and Chris did some rethinking of the original concept/setup, it was decided that the car would be a front mount (down low), air to air intercooled twin turbo set up using PTE6466s strapped to a LME supplied 427 (Dart Next II aluminum block) stuffed with a billet crank, forged internals, topped with All Pro 12-4 heads and a LME billet intake. ECS decided to run a Pro Efi 128 with all the bells and whistles. The car retained all factory creature comforts and now sports a new stereo with 3200 watts of Zapco power and speakers/subs from Hybrid Audio Technologies. It is running on pump and meth for the street with a choice of either e85/98 or pump/meth mixed with a health dose of MS109 at the events.
The engine bay was reassembled (for the last time) late last month. The fenders and hood are still off and the interior is half together. This past week, Doug got to tuning.
The first pull on their DynaPack yielded in excess of 1000 whpr at 15lbs (10lb spring in the waste gate), pig rich with no timing on pump and meth. When Doug leaned it out, the next pull shut down the dyno.....
ECS put in a 7 lb spring (we need less boost as cutting boost in the first Pro Efi line of defense for traction control) and re-ran the car, this time on e85. First (and only pull thus far on e85) pull made 910/800 at 10 psi on a conservative (relatively speaking) tune. I am looking forward to the car getting dialed in, fully tuned, then raced this year - SRE, WGF and other events - while it will see a fair amount of street use (to and from the office, some other car related events).
Can't wait to see where ECS takes the car from here once Doug turns up the boost. There is likely to be a swap to a power glide at some point in 2018 for 1/4 mile passes (then back to the manual transmission).
Big thanks to Alex, Chris, and Doug for undertaking the build and as well to their head tech Ed for all the wrench work it took to get to this point.

Thanks. Finally done. Now comes the tuning and testing and so on and so on. I will be at the SRE 4.21.18 event for shaking it down, getting used to it (its been a while since I have driven it) and datalogging stuff before we turn it up at the track.

Just to nip some of the PM's in the bud, no this will not be made into a turbo kit for sale, but thank you for your interest. 
We originally went in with the plans to do so but this system is simply too complicated and custom.
It is a shame though, we would have liked too. This is the highest HP per lb of boost build we have put out of ECS.

ECS really squeezed 10lbs of crap into a 2 lb bag to get this done. Packaging is tight and many items were relocated - fuse box, battery, a/c compressor, just about every line under the hood and a bunch of wires. Invaded space in the wheel wheels, behind panels, behind fenders, and behind the dash for mounting all kinds of things like the Pro Efi and interface pieces, fuel system, meth system, various coolers and other odds, ends and electronics. A dry sump oiling system was added, using up even more real estate under the hood. Then, just to add to the challenge of squeezing more stuff into this already tight package, I asked them to include a fire suppression system in the car and then had them hide that bottle too (its the size of a 10lb propane bottle). Hell, even the subwoofer enclosure is under the car and resides where the mufflers used to be (false floor in the trunk, very stealth - targa roof still fits) and the front mids/his are mounted in custom carbon fiber A pillars while the Pro Efi controls are hidden from the eyes of the wife, child and valet parking attendants.
With the hood closed but the doors/trunk open, the car appears to be stock.
