You might want to sort out your gear ratios a bit for your Murcielago and 911 Turbo cause even with Stage 3 components they should still be able to hit 250mph quite easily.
Upcoming drag projects:
-My own 2006 Ford Mustang GT set up (which currently does about 7.3 seconds and can actually get close to 250mph)
-My own Dodge Charger R/T set up (which currently incomplete can manage 7.03 seconds!)
-My Supra set up for Wheelie competitions
