To help out a bit, I have 336kw at the wheels in my T, My mates LS1 has 245rwkw. Both are utes with low K's, 9/10 times he has a better launch than me (still have burnout 245's on the rear wich are hard compund though), but they are easy to catch after 2nd gear, wheel spin is the killer - my mate never seems to have this drama as his car isn't powerful enough to worry about spinning in 1st, second, mid third...
