I am approaching 500 myself. I took a run out to Bandimere Speedway tonight for a little M&G and watch a few of the local LX Forum guys do some runs with their Magnums. (No, the Daytona is staying on the sidelines until spring.)
FYI, Jim (Moderator) on FXForum pulled a 15.6 with a reaction time of .002! (temp was 50, humidity around 70-80%, altitude 6000') so that would probably equate to a mid to low 14 at sea-level. Had fun and got to actually meet some folks finally.
