I have 265rwkws in a ute and run 12.7@109mph on street tyres (stock SP3000 at 20psi), I believe the utes have an advantage at the strip because of the "live" rear axle and the way it puts the power to the ground, however too much can be a problem with wheel spin when launching, I find that stalling to 2200-2300rpm too much and get excessive wheel spin, stalling to 1700-1800rpm not enough next outing I will try between 1950-2100rpm, with that and everything else going right I hope to run 12.5
