Yeah what he said!!!!!!!!! And you don't weigh 230!Weight is huge for 60' times...takes a lot of power to move a big guy on a big sled...I'm 245 in my leathers, have a z1 turbo with a NOS shot, with NOS coming in 1 sec. into run, was running 1.36 - 60'....NOS coming on 1/10 sec after launch, 1.29 - 60'....put a young lady who is a 105 lbs lighter on it...no changes...1.19 - 60'...moral of the story??? Just drive it and have fun, and work on consistancy, win some races!!!!
