AMS appears to be in the lead on the AWD E63 tuning path. Their current street tune with exhaust is 10.8 @ 128.

I'm a road course guy, so all this straight line stuff is a bit of a mystery to me.

Have not seen a PTTS around here, so no clue of actual comparative grunt.


And yes, give us a proper "build" thread. Compensation for time spent updating will be remitted upon completion. lol

 

Now if we talking tuned AMG - ya no doubt just awesome potential there with the 5.5 biturbo. AMS, Brabus, Renntech...

This concept doesn't excite you?:

 

Tuned PTT with upgraded turbos should come in close to the gemballa panamera. Although fvd claims their stage 4 is over 800 hp to crank so could be a little better:

0-125 in 9.6s so should run mid 10s quarter mile @ prob high 130s... 60-130 high 6s hopefully. The gemballa pani also does 187mph in 25s.

 

This won't be faster than an E63S with the same upgrade.

 

Agree...
