Thanks Ranch
Unsure how much I could gain out of intake systen they don't seem to be too restrictive and flow nicely .
Throttle body - maxbore are willing to upgrade 75mms to 78mm.. not really worth it
Diet time yes !!
There isn't a huge amount I can do however I was thinking lighter wheels and shedding the large style rear muffler would help .

DSC, TRAC-DSC or no DSC?
Raise the revs while holding the car on the brake pedal or just boot it when the lights go green?
Foot flat to the floor or ease the revs in gently?
Let down the tyres or run at the normal pressure?
Any other tips?

Well, I ran my XKR on the same night as Steve.
DSC off completely, big smokey burnout to warm up the tyres, boot it on the last yellow.
Actually launched OK, even without the LSD, I also did a couple of 2.0 60ft's, a 1.9x once too.
Mind you I had brand new Michelin Pilot Sport 4S 295's on the back, which would have also helped.
Tyres are very important for traction...

-Put shifter in DS .
-Hold down dsc button for approx 8-10 sec a chime will indicate it's turned off .
-Paddle shift down to first so you can heat up the tyres with a lengthly burnout
-After heating up the tyres the transmission would have shifted up to 3rd so put back into 1st via paddle shifter
-At the line dial up the revs just before you break traction then release brake pedal and depress accelerate (I went approx 50% throttle for approx half second then fully depressed)

Also I never heated street tires. They tended to just get slicker. Quick bunny hop after the water to rub anything off the tread and pull up to the line. 'No water' on the windshield keeps the tires from getting too wet. I had a set of cheap meaty Fulda's on my '93 stang that would launch like ET streets. My 60' times were never great but the car pulled hard in the top end, 11.73 @ 119 mpg with a 400 hp torque built 302. 10-1 comp with a very mild cam and 5 psi of Paxton helping.
Single track is just asking for the right tire to break loose easier. Again, clean get away so you can get on the throttle hard. Top end speed says HP, Low ET equal efficiency. Our combos will not be efficient.
