[QUOTE=David88vert;39217780]Ok, let me make this simple, as a lot of people don't understand the difference in what they are measuring with the two types.

A normal Dig is for a set distance - typically 1/8 or 1/4 mile. You are measuring two cars being marked at the same starting point, and being given the same exact signal (usually from a 3rd party), and racing to a set finishing point. It's very controlled, and easily monitored for leaving early, and for which reaches the finish line first.

Rolls as they are being done around here are typically stated from a start MPH to an end MPH. This is not the same type of measurement. The cars are not actually at the exact same speed, the exact same starting position, and have no set finishing point. Even the start isn't the same, as the one signalling through honking knows the exact timing, and the other will have a slight delay before they even can physically hear the honk. It is not easily monitored for if they jump, or if they lie about reaching their stated finishing speed. They are simply comparing accelleration, but not in a fair manner where both have the same chance. One driver will always have an advantage over the other.

In order to make a roll race closer to the standards of a drag race, both cars need to maintain a set speed exactly next to each other up to a set start point (signpost, line on road, etc), and then race to a set finsh point (signpost, bridge, line, etc). A camera needs to be used at both start line and finish line to make certain that one driver does not leave early. Unfortunately, this effort makes it easier to just do what they should have in the first place - a dig run.



very true, cant have said it any better sweet mustang and bike btw!
Dig is the only way to go.
