|RedSStreak||Wow I spoke too soon on the go boosted thing. I love how none of your toys stay the stock slowpokes that they were.... When you quarter it, please let me know the ET time|

This setup was built for my higher altitude and 91 octane, and was a auto, and now a geared auto. These things were limitations presented to Andy at ADM, and would cost us some power, as a tune for 93 Octane and/or better meant Andy would have added more timing, and made more power. Also as everyone knows, auto's dyno lower, and a geared one even lower.
With that said Andy at ADM blew us away.... He did this entire build in 2 days, kept the car for a 3rd day breaking the engine/gears in, ensuring no leaks or issues, as well as street tuning and data logging..
Chantilly gave me these numbers, looking at the graph you will see the pre dyno numbers and the post, notice the car now redlines at 6800rpm and notice the new hp at redline as oppose to the pre redline hp number:
Now Chantilly roams around hunting her prey, the only clue might be her fat 11 inch rear wheels with 315's, other then that, she looks normal, especially with the stock exhaust on..

the car is a A6 auto...
New 3:45 rear end gears were installed.
ADM fuel pump/system installed
Tranny and engine tuned by ADM via HP Tuners.
When everything was removed, the car was just a shell, no engine, no tranny, no rear end, no gas tank. Total build time.... 2 DAYS.
Chantilly sitting pretty on ADM's dyno, Chantilly was dirty from the drive to the Dallas area, and also from being disassemble and then reassembled, and yet her paint looks wet and fresh:

2.9l Whipple fitted:
Install complete and she fires up, car now has 3:45 rearend gears, ADM fuel system;
ADM stealth boost guage, looks factory and keeps the car looking sleeper and stockish, I have never been a fan of the pillar guages:

Old L99 VVT camshaft, crappy lifters, cam phaser removed:
assembly begins, notched pistons lowering compression looking real
Bolt the heads on using same head gaskets as the ZR1 LS9 engine.

Engine teardown begins, Pistons and cylinder walls after 12k miles:
GT11 Boost friendly camshaft for a LS3 conversion.
Lingenfelter LS3 CNC ported complete cylinder heads with light-weight hollow stem intake valves and heavy duty inconel exhaust valves that are designed to be durable even under extreme high temperature conditions seen with supercharged or turbocharged applications.
LS3 cylinder heads are precision CNC machined on a 5 axis CNC machine to ensure that tight tolerances are maintained. The Lingenfelter CNC porting procedure is a computer controlled machining operation that duplicates details from a finished Lingenfelter hand ported cylinder head. The port and chambers are carefully designed to provide the best combination of high flow capabilities across the entire valve lift range. The Lingenfelter quality control procedures include sectioning sample cylinder heads to confirm minimum wall thicknesses.
Following porting each head receives: Precision 3 angle valve job to maximize flow & provide extended life, CC checking chamber size for correct compression, surfacing to insure deck flatness, deburring, pressure testing, professional assembly, setting spring height & checking all tolerances, and serial number:

Chantilly needed new spark plugs...
When I get a new car that I know I will demand more power from, I tend to wait a year or so, give the car some time to see if any warantee issues might pop up... put atleast 10k miles on it....
Chantillys time came....
Long tube 1 7/8 headers were installed, Cold air intake, CNC machined throttle body, all cats and mufflers removed, and a tune... that only netted
366hp and 386tq.... which is far short of my standards...
So off the car went to ADM Performance nearby Dallas..
They did a pre dyno and netted the numbers above, which matched my local dyno within a few hp, as SAE numbers probably should.
Now was time for the teardown... Andy of ADM was presented with a tough goal (as I had target numbers) and hit him with limitations, such as the car is a auto (which always dyno lower), the rearend needs gears, the setup must be 91 octane friendly, car is to loud, put the stock exhaust back on, and a time limitation..
Chantilly on the lift after all fluids drained, hoses/wires removed:
Entire drivetrain on its way out:
The car wound up being a shell, and one wondered if she would ever live again, as the engine, tranny, rearend, gastank were all removed..
With the drivetrain on the ground, the dissasembly and engine build can be done while Chantilly safely sits high above on the lift..
