This is an awesome little tool I found on dragtimes.com that converts times from one track to another based on conditions. We are always talking about different scenarios and power lost etc, etc. now if we can take note of all of the factors day to day track to track we can just punch in the numbers and the calculator will correct for conditions. Attention: Any Mod, this should be a sticky in the Drag Racing forum Only drawback is that you will have to convert your 1/8th mile time to 1/4 time.
