Check here for some ideas:

12.29@115MPH...1.89 ON PILOT SPORTS..120 trap speed should get me in the 11.70's range i hope..

hope to pick up .5 tenths and 5 mph with a tune....

you should be golden, thats pretty good for a car that ways ~ 4800lbs with driver....

post some timeslips when you are done, or even better a video clip.

i'm trapping 114-116 now and i can't any faster than 12.30's stock.. with a good tune will i see lower 120's trap speed???

Yes you should most tunes add around 50whp

You realize you are in Eurocharged territory, why not set up for a dyno tune and TCU. You'd be surpised the gains on 600s are more than 50rwhp. You will need drag radials to get decent traction, I've learned street tires become a waste of time. With a tune and tires you should see mid-lower 11's with 120-123 mph. The sl600 record car is close to breaking into 10's with only ecu/tcu and drag radials. The guy's not even a good driver!!!!(benz-o-rama) Actually its in his blood, he's very good and alot of help as well. Good luck!!!

THANKS...seems i got a monster to unleash...

Lol....yeah, I'm still learning.

OP, if I recall, my best time on street tires (all season) was an 11.2x I think. It's very hard to launch a tuned V12TT on streets. Pointless, really..

Get a set of DRs....it makes you a better driver than you really are.
