The 0 to 100 figure is not from a Dyno Sheet but in real world conditions with a stop watch so i guess it could be on the higher side by not more than half a second and i say this because i did four runs and there was a friend with me in the car, added wieght. But yes testing it on the Dyno is the next logical step. There is one with a friend in islamabad and i guess its time to go see him.
By the way an amazing job with th that Mark II with a 2JZGTE
Take care mate
