What can the 5.5 really do?

The Porsche tuners I've called agree that the tranny can hold up to a lot of abuse as they have thrown more and more power at it, and it still holds up.
I think at 130mph we'll be at the limit for our drivetrains, realistically. I know DerekFSU is there now but he's already he said "he doesn't give a F if it blows up" while I think the rest of us do. 130mph is FLYING and right there in Enzo/CGT territory so it's really nothing to scoff at.
Again, I know our trannies aren't weak, but to get a 4000lb car to run 130mph traps is just insane on a production drivetrain.

So what is the formula to get an 11.5 sec car?
-Weight reduction (You can get this car down to 3850 without any compromise to luxury)
-Wheels -40
-Brakes -34
-Light weight battery -40
-Remove Spare -50? (I have not weighed the spare, just a guess)
-Remove under hood insulation (It can and should be done, it will not compromise the paint) -5-10
-Boost (Marcus, how much can this blower put out?)
-Transmission (It will hold for this trap easily)
-Heat Reduction (FMIC or TMIC)
Then we go for the 10's

If we had a CF hood that would take away more weight from our E55 sled. By the way I think we would be VERY hard pressed to knock off 40lbs off the wheels unless you stuck with a 19-20lb rim and stayed with an 18 in. Btw, what out there looks half decent and weights under 20lbs?
This is how I knocked out 225 lbs from my S4 Audi. I was about to go with 18lb seats but then it would have lost its luxo audi feel.
- 25lbs exhaust system incl DPs
- 50 between tires and rims (18 inch SSR comps @16.5 lbs each)
- 25 brakes
- 40 light battery
- 25 CF hood
- 40 battery
- 10 misc crap
- 20 lightened flywheel
+10 FMIC
