The figures MrBlonde gave are indicative of ideal runs and are a very good guide as to what a well sorted car can achieve on a good run. Not all runs are ideal and therefore other factors (such as wheelspin, pedalling, slow gear changes, backing off, car out of shape etc) will see variations on those guides. There are other figures that will give further indication as to how the run went, such as 330', 660' and 1000' times and speeds.
